Taurine is one of the most abundant free amino acids in the human body, concentrated in the brain, heart, skeletal muscle and retina. Unlike most amino acids it is not built into proteins; it sits free inside the cell and takes part in bile acid conjugation, the movement of water and electrolytes across cell membranes, and calcium signalling. Primabolics L-Taurine Capsules present taurine on its own, with no flavouring and no proprietary blend, in a capsule bottle that is Australian owned and manufactured. It is commonly used by active adults as a stand-alone amino acid or alongside intra-workout and evening formulas. Taurine turns up in most intra-workout and energy formulas, and the capsule is for people who would rather take it on its own, in the morning or beside an evening formula, than have it fixed inside somebody else's blend.

Product Strengths

Lets taurine intake be set on its own, apart from what an intra-workout formula already provides.
Single-ingredient taurine, with no fillers or proprietary blends.
Capsule format, so there is nothing to weigh or mix.
Unflavoured, so it stacks with anything else you take.
Australian owned and manufactured.

Taurine

What is taurine used for?

Taurine is used for everyday support of a healthy heart, which is where its trial evidence is strongest. Your heart muscle is packed with taurine, and a plain capsule or powder gives you the form the trials used.

Is Taurine right for you?

Taurine is well tolerated in trials, and most of the questions we get are about what it's really for. These are the questions our naturopaths ask in store.

A good fit if

You're an adult looking to support your heart health and you want the form the trials used
You'd like taurine without the caffeine and sugar in an energy drink
You're happy with a daily supplement and a steady, modest effect rather than something you feel straight away

Check with us first if

You take blood pressure medicine. Taurine affects the same measure, and the combination hasn't been studied.
You take insulin or other diabetes medicine. Taurine changed glucose measures in trials, so the effects could add up.
You're using a high-dose pre-workout with lots of ingredients alongside very hard training.

How the forms compare

Taurine capsule or powder. Best known for: The form used in nearly every clinical trial, usually at 1.5 to 3 g a day. Absorption: We found no study comparing forms. Blood taurine rose on 1.6 g a day in a 12-week trial. Typical use: Taken daily on its own, without caffeine.
Energy drink. Best known for: Regulated as a food, not a medicine, with a legal limit of 2,000 mg in a one-day quantity. Absorption: Not measured separately. Typical use: A quick lift, but reviews put that down to the caffeine and sugar rather than the taurine.
Taurine with caffeine (pre-workout). Best known for: In a network meta-analysis, the pairing improved anaerobic capacity and reaction time more than either on its own. Absorption: Not measured separately. Typical use: Before training. The evidence is mixed, and another review calls any extra benefit from the pairing implausible.
Magnesium taurate. Best known for: Sold as a calming or heart-friendly magnesium. Absorption: We found no human study. Typical use: Not a listed ingredient in its own right in Australia, and it won't give you the 1.6 to 3 g of taurine the trials used.

Common questions

Isn't taurine just the stuff in energy drinks?

It's the same substance, but the amount and the rules are different. An energy drink is regulated as a food and capped at 2,000 mg of taurine in a day's serving. A supplement is regulated as a medicine ingredient, with no cap on the ingredient. And the kick you feel from a can isn't really the taurine. Reviews of energy drinks put their effects on the heart and on performance down to the caffeine and sugar.

Does taurine help you live longer?

In mice and monkeys, a 2023 study in the journal Science found taurine extended healthy lifespan, which is why so many people ask. In humans, it's only a link so far. People with lower taurine tend to be older or less healthy, but that doesn't show that taking it changes anything. The researchers called for human trials, and the first ones haven't reported yet.

Is magnesium taurate a good way to get taurine?

Not if taurine is what you're after. The trials used free taurine at 1.6 to 3 g a day, and a magnesium taurate tablet gives you far less than that. Magnesium taurate also isn't listed as an ingredient of its own in Australia. You can take taurine and magnesium together, but that's two products doing two separate jobs, not one special form.

How much, and when

Reference values. There's no recommended intake for taurine. Your body makes its own from cysteine, so it's classed as conditionally essential rather than essential.

Typical supplemental range. Trials mostly used 1.5 to 3 g a day, which a large pooled analysis found was the most effective range. The best-known heart trial used 1.6 g a day for 12 weeks. Capsules in Australia are usually 500 to 1,000 mg, so two or three a day gets you to a trial dose.

Upper level. The TGA sets no daily cap on taurine in listed medicines. A formal risk assessment found strong evidence of no side effects at up to 3 g a day in healthy adults. Trials have used more, but the data above 3 g wasn't strong enough for a confident long-term conclusion.

Worth knowing. What you need depends on your age, diet and health, so talk to one of our naturopaths.

Food sources

Food first, where the diet allows it.

Meat, fish and shellfish: the main dietary sources. Reliable amounts per serve weren't available in our sources
Energy drinks: about 342 mg per 100 mL on average
Energy drink, legal maximum: 2,000 mg of taurine per one-day quantity

Before you start

If any of these sound like you, talk to one of our naturopaths or your doctor before you start.

Blood pressure medicines. Pooled trials show taurine lowers blood pressure, so an added effect is foreseeable. There's no interaction study, so talk to your prescriber.
Glucose-lowering medicines, including insulin. Taurine lowered fasting glucose and HbA1c in trials, including in people on medicine for type 2 diabetes. There's no interaction study, so talk to your prescriber.
Pregnancy and breastfeeding. There's no trial evidence, as these groups were excluded from trials. We don't recommend it.
Children and teenagers. We don't recommend taurine supplements outside clinical care.
A known sensitivity to taurine. Trials excluded people with it. Don't take it.
High-dose multi-ingredient pre-workouts with extreme training. There's one case of severe muscle breakdown (rhabdomyolysis) with kidney and liver injury, though it wasn't attributed to taurine.
Dose. The safety ceiling with strong evidence is 3 g a day in healthy adults.

The evidence, and its limits

Across 20 randomised trials in 808 people, taurine improved measures of heart function, with no significant side effects compared with control. (DOI record)
A pooled analysis of 34 trials found 1.5 to 3 g a day was the most effective range for heart and metabolic markers. (DOI record)
Seven randomised trials in 402 people found taurine, on its own or with exercise, didn't improve cognitive test scores. (DOI record)
According to the sports nutrition position stand, the performance effect of energy drinks comes mainly from caffeine and carbohydrate. (DOI record)
The 2023 lifespan findings came from mice and monkeys. In people, falling taurine with age is only a correlation so far. (DOI record)

How it works

Think of taurine as your cells' housekeeper rather than a building block. It isn't built into protein. Instead it floats free inside your cells and keeps conditions steady. It helps them manage their water balance and how calcium moves in and out, which matters in muscle that works all day, like your heart. It also helps handle oxidative stress. In your liver, it's joined to bile acids to make the bile salts you use to digest fat. In your brain, it acts on GABA-A receptors, the same calming signal system many sedatives work on. Your body makes some from the amino acid cysteine, so it's called conditionally essential.

The Australian rules

Taurine is item 4868 on Australia's permitted ingredients list (Schedule 1), and it's allowed in listed medicines with no daily cap, no limit on how it's taken and no specific requirement. It's also allowed in food, but only in formulated caffeinated drinks, where the rules are different: a drink can carry up to 2,000 mg of taurine in a one-day quantity. So an energy drink and a taurine capsule sit under two different laws with two different limits. There's also no permitted indication about blood pressure at all, so a listed medicine can't make one. Magnesium taurate doesn't appear as an ingredient of its own. Being allowed isn't the government endorsing any product or claim.

Read the instrument: Schedule 1, item 4868.
