The best vitamins for energy are the ones that fill a gap you actually have. That could be iron if your iron stores are low, vitamin B12 if you eat little or no animal food or you're over 50, or vitamin D if your levels drop through winter. Tiredness has many causes, so the right choice starts with yours.
Iron has some of the clearest research for tiredness, in women with low iron stores who weren't anaemic [1]. Vitamin B12 is one of the most popular energy vitamins. Yet it doesn't appear to improve performance unless you're low in it [2]. In people who weren't deficient, it didn't change thinking skills or mood scores either [3].
In terms of our top pick, we recommend Live More You Nutraceuticals Creatine Monohydrate Micronised. It's one unflavoured 5 g scoop a day of 100% micronised creatine monohydrate, for about 50 cents a day. It's sold as a sports food, so we don't make health claims for it here.
We've compared 9 of the best vitamins and supplements for energy from our Energy Boost Vitamins range of more than 100 products and our wider range. We looked at the research on each key ingredient, who it applies to, the dose, regulatory status, cost per day and customer reviews, to help you choose with confidence.
Always read the label and follow the directions for use. If symptoms persist, talk to your healthcare professional.
What Affects Your Energy Levels?
Feeling tired is a very common complaint. The cause is often everyday life: short or broken sleep, a busy schedule, too little movement, a patchy diet, or too much caffeine or alcohol [4]. Tiredness can also come from low iron or anaemia, sleep apnoea, an underactive thyroid, diabetes, stress, anxiety or depression [4]. That's why foundations come first and supplements come second.
Some people are more likely to have a gap. People who have periods, are pregnant or breastfeeding need more iron, and vegetarians and vegans may get less of it [5]. Vitamin B12 is more likely to run low in vegans, older adults and people taking metformin or stomach-acid medicines [2]. Strict vegans need a B12 supplement [6]. In 2011-12, just under one in four Australian adults (23%) had a vitamin D deficiency, rising to 36% in winter [7]. Gut conditions can also lower how much magnesium you absorb [8]; for gut support, read Best Vitamins and Supplements for Gut Health in Australia (2026 Guide).

Can Vitamins and Supplements Help With Energy?
Vitamins and minerals help your body turn food into energy, but taking more than you need won't give you extra. Nutrient supplements tend to help most when your body is low in them. If you've felt tired for more than 2 weeks and it isn't improving, see your doctor, because tiredness can be a sign of something that needs treatment [4].

Who Each Energy Supplement Helps Most
Most lists rank energy vitamins as if they work the same for everyone. The trials say otherwise: most of the clearest results come from people who were low to begin with.
| Ingredient | Clearest Results In | Little or No Effect Seen In | How Soon |
|---|---|---|---|
| Iron | Women aged 18 to 53 with tiredness, low iron stores (ferritin, the iron storage protein, below 50 µg/L) and no anaemia: fatigue scores fell 48% with iron and 29% with a placebo, a dummy pill [1]. A review of 18 trials in iron-deficient adults without anaemia found less self-reported fatigue in the 4 trials that measured it [9] | Quality of life, depression and anxiety scores didn't change [1], and fitness tests such as maximal oxygen uptake didn't improve [9] | 12 weeks in the main trial, which used 80 mg of iron a day as ferrous sulfate, with blood markers checked after 6 weeks [1] |
| Vitamin B12 | People who are low in B12, where fatigue is one of the signs [2] | People who aren't deficient: across 16 trials with 6,276 people, B12 didn't change thinking skills or depressive symptoms [3], and it doesn't appear to help performance without a deficiency [2] | Depends on how low you are, so ask your GP about a follow-up test |
| Multivitamins with B vitamins | Generally healthy adults in 8 trials lasting at least 28 days: perceived stress and fatigue were lower [10] | Depression scores didn't change significantly [10] | At least 4 weeks in the trials [10] |
| Vitamin D | 120 adults (average age 29) with tiredness and low vitamin D: a single 100,000 IU dose improved fatigue scores more than a placebo [11] | The trial only included people who were low, so it doesn't show a benefit for people with normal levels [11] | 4 weeks [11] |
| Creatine | Healthy adults doing high-intensity exercise [12]. In 15 healthy young adults kept awake for most of a night, a single dose of 0.35 g per kg (about five times a 5 g serve) improved processing speed [13] | Short reaction-time tasks after a mentally tiring task [14], and thinking tasks in young adults [15]. Research on creatine and lost sleep is still small [16] | Usually several weeks of daily use to build up stores [13] |
| Coenzyme Q10 (CoQ10) | 13 trials with 1,126 people, most living with a health condition: fatigue scores fell [17] | In the 3 trials of healthy people, the drop wasn't statistically significant [17] | 4 to 24 weeks, with bigger effects at higher doses and over longer periods [17] |
| Ginseng | General tiredness not linked to a specific disease, with a small effect. In 4 trials, formulas combining ginseng with other herbs showed a small drop in fatigue [18] | Across all 19 trials, the overall drop in fatigue wasn't statistically significant. Trials of ginseng on its own showed no significant drop [18] | 2 to 16 weeks [18] |
Who funded the research: Pierre Fabre Médicament sponsored and funded the iron trial [1]. The EMDO Foundation partly funded the vitamin D trial [11]. Forschungszentrum Jülich and RWTH Aachen funded the creatine and lost-sleep trial [13]. The Council for Responsible Nutrition, a US supplement industry body, supported the creatine position stand [12]. National Taiwan University Hospital, Taiwan's Ministry of Science and Technology and the Taiwan Society of Ultrasound in Medicine funded the CoQ10 review [17].
Check for a Shortfall First
A blood test from your GP stops you paying for something you don't need. It's also the only reliable way to know if you're low in iron [5]. Ask about these before you start.
| Nutrient | What the Research Shows | Ask Your GP About | Our Pick |
|---|---|---|---|
| Iron | If you're low in iron, you may just feel tired and run down [5]. Iron reduced fatigue in women whose ferritin was below 50 µg/L [1] | Iron studies, including ferritin, especially if you have periods, are pregnant or eat a plant-based diet | Ethical Nutrients Mega Iron, if your diet is low in iron. If a test shows you're deficient, follow your GP's treatment advice |
| Vitamin B12 | Fatigue is a sign of B12 deficiency [2]. Absorption from food can fall with age [6] | A vitamin B12 blood test, especially if you're vegan, over 50, or take metformin or stomach-acid medicines | Herbs of Gold Activated Sublingual B12 |
| Vitamin D | 23% of Australian adults had a deficiency, and 36% in winter [7] | A vitamin D blood test, also called 25(OH)D, especially in winter or if you're indoors most of the day | A multi with 1,000 IU, such as Herbs of Gold Womens Multi +, or our Vitamin D Supplements range |
| Magnesium | Your body needs magnesium to produce energy, and fatigue and weakness are early signs of a deficiency [8] | Your usual intake, and a test if you have type 2 diabetes, a gut condition or take long-term reflux medicine | Ethical Nutrients Mega Magnesium Glycinate 5 in 1 |
Your GP may also check your thyroid and blood count, because an underactive thyroid and anaemia can both cause tiredness [4].
What Makes a Good Energy Supplement?
Energy supplements vary more than most people realise. Five things separate a well-made supplement in our Energy Boost Vitamins range from an average one.
- Clear Australian regulatory status. Look for an AUST L number, which shows the product is listed with the Therapeutic Goods Administration (TGA) and made to its manufacturing standards. Sports foods and foods follow food rules and can't make the same health claims.
- A match to the gap you have. Iron helps when your iron is low, and B12 when your B12 is low. A product built around the wrong nutrient won't help, however good it is.
- Named ingredients and full doses. Every active ingredient should be listed with its amount, with no hidden proprietary blends.
- Realistic timeframes. Most of the trials cited ran for 4 to 24 weeks. Be wary of anything promising instant energy.
- A dose that stays within upper limits across your products. Vitamin B6 and iron appear in many formulas. Australia's adult upper limit for vitamin B6 is 50 mg a day [19], so check the total across everything you take.
Every product on our list was assessed against these criteria: dose, regulation, research and label content.
Comparing the Best Vitamins and Supplements for Energy in Australia
1. Live More You Nutraceuticals Creatine Monohydrate Micronised (Top Pick)
One ingredient, one scoop, once a day. Each 5 g serve is 100% micronised creatine monohydrate (200 mesh). It's unflavoured, so you can mix it into 150 to 250 ml of water or non-acidic juice as part of your morning. You can take it before or after a workout.
The 500 g tub holds 100 serves, more than three months of daily use. At $49.95 on 9 November 2026 (a sale price, down from $54.95), that works out to about 50 cents a day.
It's sold as a sports food, so we don't make health claims for it here. Don't have more than 1 serving a day. The pack says it's not suitable for children under 18 years of age or pregnant women. Sports foods carry the statement: Not suitable for children under 15 years of age or pregnant women: Should only be used under medical or dietetic supervision. Browse more forms in our Creatine Supplements range, or see Creatine Women.
"Live More You creatine has been awesome! Plus it dissolves well, unlike some."
Key details: 500 g tub, 100 serves | 5 g once a day | Micronised creatine monohydrate 5 g per serve | Unflavoured, no other ingredients | Sports food
2. Herbs of Gold Activated B Complex
The eight B vitamins work together in the chemical reactions that release energy from food. A review of their role in the brain argued that, without an optimal diet, taking the whole B group would be a rational approach for brain health [20]. PGT Healthcare, which makes multivitamin products, funded the review.
One capsule gives you thiamine 22.3 mg, riboflavin 18.3 mg, nicotinamide 25 mg, pantothenic acid 22.9 mg, vitamin B6 as P5P (pyridoxal 5-phosphate, equal to 15.95 mg pyridoxine), folate as levomefolic acid 400 mcg and vitamin B12 as mecobalamin 400 mcg. The B6, folate and B12 are in activated forms, which your body uses without converting them first.
It supports energy production, a healthy stress response and nervous system function. Adults take 1 capsule a day with food, so the 60-capsule pack lasts two months. Stop taking it if you experience tingling, burning or numbness and see your healthcare practitioner as soon as possible (it contains vitamin B6). If you also take Herbs of Gold Womens Multi + or Mens Multi +, adding this takes your vitamin B6 over the 50 mg adult upper limit [19]. Vitamins can only be of assistance if dietary intake is inadequate. Compare more in our Vitamin B Complex Supplements range.
"This supplement is easy to take, and as a vegetarian I feel it provides what I used to get from meat."
"Good value absorbable vitamin b"
"I found this product great value after researching online websites."
Key details: 30 or 60 capsules | 1 capsule daily with food | 7 B vitamins, including B12 400 mcg | AUST L 310449
3. Herbs of Gold Activated Sublingual B12
Vitamin B12 is found naturally in animal foods, so strict vegans need a supplement, and older adults can absorb less of it from food [6]. Fatigue is one of the signs of a B12 deficiency [2]. If you're not low, extra B12 doesn't appear to improve performance [2].
Each tablet gives you 1,000 mcg of mecobalamin, the active form of B12, and dissolves under your tongue, so there's nothing to swallow. It supports energy production, healthy red blood cell production and nervous system function, and helps prevent dietary B12 deficiency. Adults dissolve 1 tablet under the tongue daily. Vitamins can only be of assistance if dietary intake is inadequate. At $21.89 for 75 tablets on 9 November 2026 (a sale price), it's about 29 cents a day, the lowest cost per day on our list. Find more in our Vitamin B12 Supplements range.
"This is a superior b12 ..Xcellent product."
"Easy meltable vitamin b12 love it!"
"Long time user of these items. Still happy"
Key details: 75 tablets | 1 tablet daily, dissolved under the tongue | Mecobalamin (active vitamin B12) 1,000 mcg | AUST L 266757
4. Ethical Nutrients Mega Iron
Each capsule gives you 24 mg of iron as iron amino acid chelate (iron diglycinate), with 80 mg of vitamin C, mecobalamin (B12) 500 mcg, folate as levomefolic acid 200 mcg and vitamin B6 (pyridoxine 4.12 mg). Vitamin C helps your body absorb iron from plant foods [21]. Its permitted indications include relieving tiredness and feelings of weakness when dietary intake is inadequate, and maintaining energy levels and iron levels, including in vegetarians and vegans.
A blood test is the only reliable way to know if you're low in iron [5]. If a test shows you're deficient, follow your GP's treatment advice. Adults take 1 capsule daily with food and drink plenty of water. It's not for the treatment of iron deficiency conditions. Vitamins and minerals can only be of assistance if dietary intake is inadequate. If symptoms persist, talk to your health professional. Iron's adult upper limit is 45 mg a day from food and supplements combined [21]. Take iron at least 4 hours apart from thyroid medicine (levothyroxine), and know that reflux medicines can reduce how much you absorb [21]. Contains iron: keep out of reach of children. At $21.95 for 30 capsules on 9 November 2026 (a sale price), it's about 73 cents a day. Compare more in our Iron Supplements range.
"Can see a result in my energy levels"
Key details: 30 capsules | 1 capsule daily with food | Iron 24 mg, vitamin C 80 mg, B12 500 mcg, folate 200 mcg | AUST L 298872
5. Ethical Nutrients Mega Magnesium Glycinate 5 in 1
Your body needs magnesium to produce energy, and fatigue and weakness are among the early signs of a deficiency [8]. Older adults and people with type 2 diabetes or gut conditions are more likely to run low [8].
Each tablet gives you 200 mg of magnesium from magnesium diglycinate and amino acid chelate, plus zinc 7 mg, vitamin B6 (pyridoxine 13.66 mg), chromium 200 mcg and selenium 13 mcg. It helps maintain energy levels, helps relieve muscle cramps and mild spasms, and supports a healthy stress response. For daily supplementation, adults take 1 tablet a day. The label also allows 1 tablet three times a day for therapeutic use. That gives you 600 mg of magnesium, above the 350 mg a day adult upper limit for magnesium from supplements [22]. Only take the higher dose on your health professional's advice. High supplement doses can cause diarrhoea [8].
Stop taking it if you experience tingling, burning or numbness and see your healthcare practitioner as soon as possible (it contains vitamin B6). It contains selenium, which is toxic in high doses: adults shouldn't exceed 150 mcg a day of selenium from dietary supplements. If you also take Herbs of Gold Womens Multi + or Mens Multi +, adding this takes your vitamin B6 over the 50 mg adult upper limit [19]. Keep magnesium at least 2 hours apart from osteoporosis medicines such as alendronate [8]. Vitamins and minerals can only be of assistance if dietary intake is inadequate. If symptoms persist, talk to your healthcare practitioner. The 240-tablet pack, at $72.95 on 9 November 2026 (a sale price), works out to about 30 cents a day at 1 tablet. Find more forms in our Magnesium Tablets & Supplements range.
"Quality product, highly recommended it and a great price at Mr Vitamins."
"Easy to take, convenient large size"
"I prefer the tablets to the powder. Easier to get a constant dose."
Key details: 60, 120 or 240 tablets | 1 tablet daily | Magnesium 200 mg, zinc 7 mg, B6, chromium and selenium per tablet | AUST L 392403
6. Herbs of Gold Ubiquinol 150mg
Each soft capsule gives you 150 mg of ubiquinol, the reduced form of CoQ10 your body uses directly. It supports energy production and heart health, and acts as an antioxidant. Adults take 1 to 2 capsules daily with food. Do not take while on warfarin therapy without medical advice. It contains sulfites. The 60-capsule pack, at $58.45 on 9 November 2026 (a sale price), works out to about 97 cents to $1.95 a day. Compare more in our Coenzyme Q10 Supplements range, and read CoQ10 for Heart Health (and a caution on Statin Medications).
"a great product that really helped me with energy, vitality and a spring in my step."
"Since taking Ubiquinol I seem to have more energy. I would recommend this product."
"Seems good to me . Easy to take small capsule ."
Key details: 30 or 60 soft capsules | 1 to 2 capsules daily with food | Ubiquinol 150 mg per capsule | AUST L 307244
7. Herbs of Gold Womens Multi +
In generally healthy adults, multivitamin and mineral supplements lowered perceived stress [10].
This one-a-day tablet covers the B vitamins, including B6 50 mg (as pyridoxine), activated B12 100 mcg and folate, plus vitamin D3 1,000 IU, vitamin C 100 mg, iron 5 mg, zinc 10 mg, iodine 150 mcg, selenium 50 mcg and grape seed. It helps convert food into energy, supports energy production and general wellbeing, and supports immune health. Adults take 1 tablet daily with food, and the 90-tablet pack lasts three months for about 51 cents a day at $45.52 on 9 November 2026 (a sale price).
That 50 mg of vitamin B6 is the adult upper limit on its own [19]. Don't add Herbs of Gold Activated B Complex or Ethical Nutrients Mega Magnesium, which both contain more. Stop taking it if you experience tingling, burning or numbness and see your healthcare practitioner as soon as possible (it contains vitamin B6). It contains selenium, which is toxic in high doses: adults shouldn't exceed 150 mcg a day of selenium from dietary supplements. Contains iron: keep out of reach of children. Vitamins and minerals can only be of assistance if dietary intake is inadequate. If symptoms persist, talk to your health professional. Browse our full Womens Vitamins range.

8. Herbs of Gold Mens Multi +
The men's version pairs a full multivitamin with four herbs. Each tablet gives you B6 50 mg (as pyridoxine), activated B12 100 mcg, vitamin D3 1,000 IU, vitamin C 100 mg, zinc 10 mg, selenium 75 mcg and iron 3 mg, plus Siberian ginseng, tribulus, damiana and KSM-66 ashwagandha. It helps convert food into energy and supports energy production, and it's traditionally used in Western herbal medicine to relieve tiredness and feelings of weakness.
Men take 1 tablet daily with food. The 60-tablet pack, at $32.92 on 9 November 2026 (a sale price), works out to about 55 cents a day. As with the women's version, the 50 mg of vitamin B6 reaches the adult upper limit on its own [19]. Don't add the B complex or the magnesium on our list. Stop taking it if you experience tingling, burning or numbness and see your healthcare practitioner as soon as possible (it contains vitamin B6). It contains selenium, which is toxic in high doses: adults shouldn't exceed 150 mcg a day of selenium from dietary supplements. Contains iron: keep out of reach of children. Vitamins and minerals can only be of assistance if dietary intake is inadequate. If symptoms persist, talk to your health professional. Browse our Men's Multivitamin range.

Key details: 30 or 60 tablets | 1 tablet daily with food, men only | 24 vitamins and minerals plus four herbs, including B6 50 mg | AUST L 313488
9. Herbs of Gold Ginseng 4 Energy Gold
If you'd prefer a herbal option, this one-a-day tablet combines Korean ginseng, Siberian ginseng and American ginseng (each from about 1 g of dried root), with ashwagandha (1.5 g) and astragalus (4.5 g). It's traditionally used in Western herbal and Ayurvedic medicine to relieve tiredness and feelings of weakness. It's also traditionally used in Western herbal medicine as an adaptogen, to help the body adapt to stress. It supports energy production too.
Adults take 1 tablet daily. Asian ginseng may be unsafe in pregnancy. If you have diabetes or take medicines that affect blood clotting, check with your doctor first, because it might lower blood sugar and interfere with blood clotting [23]. If symptoms persist, talk to your health professional. The 60-tablet pack, at $33.85 on 9 November 2026 (a sale price), works out to about 56 cents a day. Browse our Ginseng Supplements range.

Build a Simple Daily Routine
A routine is easiest to keep when it's simple. Start with one or two products that match your situation, take them at the same time each day, and give them at least 4 weeks.
- Morning: stir a scoop of Live More You Nutraceuticals Creatine Monohydrate Micronised into your water or juice, and take one Herbs of Gold Activated B Complex capsule with breakfast. Together they cost about $1.07 a day.
- With dinner: take one Ethical Nutrients Mega Magnesium Glycinate 5 in 1 tablet. All three cost about $1.38 a day, or around $42 a month. Together they keep your vitamin B6 under 30 mg a day.
Prefer fewer products? Swap the B complex and the magnesium for Herbs of Gold Womens Multi + or Mens Multi +. Don't combine a multi with either of them, because the multi's 50 mg of vitamin B6 already reaches the adult upper limit [19]. If you eat little or no meat, ask your GP about your iron before adding Ethical Nutrients Mega Iron. Not sure which combination suits you? Book a Free Naturopath Consult, Online or In Store for help choosing.
Energy Supplements by Situation
Match the pairing to your personal circumstances, then explore our in-depth guides.
Best Vitamins for Energy for Women
Iron is the first thing to check if you have periods, are pregnant or breastfeeding, or eat little meat [5]. The strongest fatigue trial for iron was in women aged 18 to 53 [1]. A one-a-day women's multi covers B vitamins, vitamin D and a little iron together. Browse our Womens Vitamins range.
Best Vitamins for Energy for Women Over 50
After 50, B12 and vitamin D become more important to check. Older adults can absorb less B12 from food [6] and vitamin D deficiency is more common in winter [7]. If tiredness came with menopause, see our Menopause Fatigue Vitamins range and Best Menopause Supplements in Australia 2026.
Best Vitamins for Men With Low Energy
People who have periods need more iron [5]. For men, ask your GP about your iron before taking it. A men's multi covers the B vitamins and vitamin D in one tablet. Men over 50 should also ask about B12, especially if they take metformin or reflux medicine [2]. Browse our Men's Multivitamin range.
What Is the Best Vitamin for Energy for Seniors?
For older adults, vitamin B12 is worth checking first: atrophic gastritis, which reduces B12 absorption, affects 8% to 9% of adults aged 65 and over [2]. Magnesium is also worth checking, because older adults tend to get and absorb less of it [8], and so is vitamin D. Because seniors often take several medicines, check any new supplement with your pharmacist or GP.
Best B Vitamin for Energy
If a test shows you're low in B12, a B12 supplement on its own targets the gap. If your diet is patchy, a B complex gives you the group together [20]. Find more options in our Vitamin B Supplements range.
Vitamins for Energy and Brain Fog
Poor sleep is a common cause of tiredness [4]. Early research suggests creatine may help thinking during lost sleep, though there are only a few studies [16]. For more options, browse our Cognition & Focus Support range.
Vitamins for Energy and Stress
In generally healthy adults, multivitamin and mineral supplements lowered both perceived stress and fatigue over at least 28 days [10]. For a closer look at stress, read Best Supplements for Stress and Anxiety in Australia.
Best Vitamins for Immune System and Energy
Herbs of Gold Womens Multi + and Mens Multi + each give you vitamin D, vitamin C and zinc in one tablet. For the full immune comparison, read Best Supplements for the Immune System in Australia. If a cold has knocked your energy, see Best Vitamins and Supplements for Cold and Flu in Australia (2026 Guide).
Vitamins for Energy, Mood and Depression: What the Evidence Says
Tiredness can be a symptom of stress, anxiety or depression [4], so it's natural to look for something that helps both. Supplements don't treat depression. In generally healthy adults, multivitamins lowered stress and fatigue but didn't significantly change depression scores [10]. B12 didn't change depressive symptoms in people who weren't deficient [3], and iron didn't change depression or anxiety scores in women with low iron stores [1].
If your mood has been low for a few weeks, or you've lost interest in things you usually enjoy, talk to your GP. They can check for both the physical and the emotional causes of tiredness.
Vitamin B12 vs B Complex: What's the Difference?
- Targets: a B12 shortfall
- Examples: Herbs of Gold Activated Sublingual B12, 1,000 mcg a tablet
- Timeframe: depends on how low you are; ask your GP about a follow-up test
- Best for: vegans, vegetarians, adults over 50, and people taking metformin or reflux medicines
- Consider: little benefit if your B12 is already normal
- Targets: the B vitamins together
- Examples: Herbs of Gold Activated B Complex, 7 B vitamins including 400 mcg of B12
- Timeframe: multivitamin trials ran for at least 4 weeks
- Best for: busy days and a diet that isn't always varied
- Consider: vitamin B6 adds up quickly if you also take a multi
Which Energy Supplement Should You Choose?
Choosing the Best Vitamins for Energy
The best vitamins for energy are the ones that fill a gap you have, so start with a blood test for iron, B12 and vitamin D. Our top pick, Live More You Nutraceuticals Creatine Monohydrate Micronised, suits active adults who want one unflavoured scoop a day, at about 50 cents a day. If you eat little or no meat, Ethical Nutrients Mega Iron supports your iron levels when your diet falls short. If you're vegan, vegetarian or over 50, Herbs of Gold Activated Sublingual B12 is the lowest cost per day on our list. For one tablet that covers the basics, choose Herbs of Gold Womens Multi + or Mens Multi +, and don't stack them with other B6 products. Whatever you choose, read the label, give it at least 4 weeks, and see your doctor if tiredness lasts more than 2 weeks without improving [4].
How to Choose the Right Energy Supplement for You
-
Start with a test
- Ask your GP about iron studies, B12 and vitamin D, especially before taking iron
- If tiredness has lasted more than 2 weeks, ask about your thyroid and blood count too
-
Match the ingredient to your gap
- Iron for low iron, B12 for low B12, vitamin D for low vitamin D
- A multi or B complex when your diet is patchy
-
Add up your totals
- Keep vitamin B6 at or under 50 mg a day across every product
- Keep selenium from supplements at or under 150 mcg a day
-
Check the label category
- Look for the AUST L number on listed medicines and verify it on the TGA's ARTG register
- Sports foods such as creatine follow food rules and carry no health claim
-
Be wary of big promises
- Promises of instant energy, or doses well above the label

Energy Vitamin FAQs
What are the best vitamins for energy?
The best vitamins for energy are the ones that fill a gap you have. Iron has the clearest results, in women with low iron stores [1], and B12 and vitamin D help most when you're low in them [2] [11]. Our top pick, Live More You Nutraceuticals Creatine Monohydrate Micronised, is one unflavoured scoop a day for about 50 cents.
Which B vitamin is best for energy?
Vitamin B12 is the one to check first. It's more likely to run low in vegans, older adults and people taking metformin or reflux medicines [2]. If you're not low, extra B12 doesn't appear to improve performance [2]. If your diet is patchy, a B complex gives you the whole group together [20].
What vitamin deficiency causes tiredness?
Low iron is one of the most common. If you're low in iron, you may just feel tired and run down [5]. Low vitamin B12 can also cause fatigue [2], and so can low magnesium [8]. Low vitamin D has been linked to tiredness too [11]. A blood test from your GP is the way to find out.
What are the best vitamins for tiredness and lack of energy?
Iron, vitamin B12, vitamin D and magnesium are the ones to check first, because they help most when you're low [5] [2] [11] [8]. In generally healthy adults, multivitamins with B vitamins also lowered fatigue over at least 4 weeks [10]. See your doctor if tiredness lasts more than 2 weeks [4].
What is the best vitamin for energy for women?
For women who have periods, iron is the first to check. In a 12-week trial, women aged 18 to 53 with low iron stores had less fatigue with iron [1]. A one-a-day women's multi such as Herbs of Gold Womens Multi + covers B vitamins, vitamin D and a little iron together.
What is the best vitamin for energy for seniors?
Vitamin B12 is worth checking first, because older adults can absorb less of it from food [6]. Vitamin D and magnesium are worth checking too [7] [8]. Check any new supplement with your pharmacist or GP if you take regular medicines.
Can vitamins help with energy and depression?
Supplements don't treat depression. Multivitamins lowered stress and fatigue in healthy adults but didn't significantly change depression scores [10], and B12 didn't change depressive symptoms in people who weren't deficient [3]. If your mood has been low for a few weeks, talk to your GP.
What two vitamins should never be taken together?
Some combinations need care. Keep iron and calcium apart, because calcium may reduce iron absorption [21]. Also add up vitamin B6 across your products, because the adult upper limit is 50 mg a day [19] and many multis, B complexes and magnesium formulas contain it.
What vitamins should I take with omeprazole?
Reflux medicines such as omeprazole can lower how much B12 and iron you absorb [2] [21], and long-term use can lower magnesium [8]. Don't change your medicine yourself; ask your GP whether to check your B12, iron and magnesium.
Are vitamin B12 injections better for energy?
B12 injections are prescription-only and are used when a doctor has diagnosed a deficiency. If you're not low, extra B12 doesn't appear to improve performance [2].
Does creatine help with tiredness?
The research is early. In 15 healthy young adults kept awake for most of a night, a single dose of 0.35 g per kg (about five times a 5 g serve) improved processing speed [13]. A review found only five studies on creatine and lost sleep [16]. Creatine is best known for supporting high-intensity exercise [12].
How long do energy supplements take to work?
Most of the trials cited ran for 4 to 24 weeks. Vitamin D improved fatigue at 4 weeks in people who were low [11], and iron at 12 weeks [1]. Give a product at least 4 weeks before deciding if it suits you.
Is there a pill that will give me energy?
No supplement replaces sleep, regular meals and movement [4]. Supplements help most when they fill a gap, such as low iron, B12 or vitamin D, so a blood test is the best place to start.
