Dr Hydrate Electrolytes Watermelon is a refreshing watermelon flavoured drink powder in a 270 g tub of 30 serves, and one levelled scoop goes straight into chilled water. It is built on soluble maize fibre and mineral salts, including trisodium citrate and Himalayan Pink Salt, with L-glutamine, acetyl-L-carnitine hydrochloride, vitamin C, a B vitamin group, zinc and selenium. The colour comes from beetroot powder and carmine, which is insect derived, so this flavour is not suitable for vegans or vegetarians.

Electrolytes

Sweat hard, or lose fluid to a stomach bug, and water alone won't put you back to normal.

You lose salts as well, and electrolytes are how you replace them. The mix matters more than the brand. An oral rehydration sachet is built to a formula, while a sports powder is usually built for taste.

Is Electrolytes right for you?

Most people reaching for electrolytes don't actually need them, and the ones who do often need a different product than the one they picked up, so here's the triage our naturopaths run.

A good fit if

You're losing fluid through vomiting, diarrhoea or heavy sweating
You're training long or hard in heat and plain water isn't cutting it
You want an oral rehydration sachet for the medicine cabinet
You've been advised to shift your sodium-to-potassium balance

Check with us first if

You've got kidney disease, because potassium handling changes and oral potassium can accumulate.
You take heart or blood pressure medicine, particularly an ACE inhibitor.
You're buying for a young child or an older person who's unwell.
You're already on a potassium or magnesium supplement.
You're using electrolytes for cramps, where the evidence is genuinely mixed.

How the forms compare

Oral rehydration salts (ORS). Best known for: Illness. Vomiting, diarrhoea, and getting a child rehydrated. Absorption: Built to a WHO and UNICEF formula for sodium, potassium, glucose and osmolarity. Typical use: The only electrolyte format with a specified composition in Australian law.
Sports hydration powders. Best known for: Training and hot-weather sweating. Absorption: Composition varies enormously by brand; often built around flavour. Typical use: Check the sodium figure, which is the one doing the work.
Effervescent tablets. Best known for: Convenience, and a measured dose per tablet. Absorption: Dissolved before drinking, so no powder to scoop. Typical use: Watch the potassium per tablet if you're on heart or blood pressure medicine.
Ready-to-drink bottles. Best known for: No mixing. Absorption: Same salts, more packaging and usually more sugar. Typical use: Convenient rather than different.
Plain sodium chloride (item 4581). Best known for: Table salt, permitted listed with no conditions at all. Absorption: The simplest and cheapest sodium source there is. Typical use: Worth remembering before paying for a branded blend.

Common questions

Do I need electrolytes, or is water enough?

For ordinary days, water's enough. Electrolytes matter when you're actually losing salts. Heavy sweating, vomiting or diarrhoea. Drinking plain water after a big sweat replaces the fluid but not the sodium, which is the reason rehydration products exist at all. If you're not losing salts, you're paying for flavoured water.

What's the difference between a rehydration sachet and a sports powder?

The sachet is built to a formula. Australian law requires oral rehydration products to match the British Pharmacopoeia and the WHO and UNICEF criteria for sodium, potassium, glucose and osmolarity once mixed. A sports powder has no such specification and is usually formulated around taste. For illness, reach for the sachet.

Will electrolytes stop my cramps?

The evidence is genuinely mixed and we'd rather say so. Thirteen randomised trials gave an inconsistent picture, and a Cochrane review of 11 trials found magnesium unlikely to prevent idiopathic or night-time cramps in older adults. One trial did find a benefit. If cramps keep happening, that's worth a conversation rather than another scoop.

How much, and when

Reference values. The NHMRC sets Nutrient Reference Values for sodium, potassium, magnesium and calcium individually rather than for electrolytes as a group. Ordinary food and drink covers them for most people most of the time.

Typical supplemental range. Oral rehydration sachets are made to a set formula, with sodium, potassium, glucose and total osmolarity matching the WHO and UNICEF criteria once mixed. Sports powders vary far more, and sodium is the figure worth comparing. Australian law caps potassium chloride at 550 mg per dosage unit in anything that isn't oral rehydration therapy.

Upper level. No single upper level applies to a blend. The binding numbers are per-ingredient: 550 mg of potassium chloride per dosage unit outside ORS, and a 3.75% concentration limit for dental use.

Worth knowing. For illness, the formula matters and a rehydration sachet is the product built for it. For sweating, sodium is the number to compare. Your needs depend on your age, diet and health circumstances. Talk to one of our naturopaths.

Food sources

Food first, where the diet allows it.

Table salt: the simplest sodium and chloride source
Fruit and vegetables: the main dietary potassium sources
Dairy, nuts and leafy greens: contribute calcium and magnesium

Before you start

This list is the part of the page we will not shorten. If any of it applies to you, talk to one of our naturopaths or your doctor before starting.

Kidney disease. Mandatory Australian warning on oral potassium chloride; potassium-induced natriuresis doesn't occur in chronic kidney disease and oral loading accumulates.
Heart or blood pressure medicines. Mandatory Australian warning on oral potassium chloride; ACE inhibitors change potassium handling.
Treated hypertension. A blood pressure increase has been noted at high potassium intakes in people on antihypertensive drugs.
Children. Mandatory warning wording includes "Keep out of reach of children"; a dehydrated child needs medical assessment.
Sodium sulfate in a blend. Carries a mandatory laxative warning where not intended as a laxative.
Anyone using electrolytes for cramps. The evidence is inconsistent and magnesium specifically was found unlikely to help in older adults.
If you take prescription medicines, check with your doctor, pharmacist or our naturopaths before starting.

The evidence, and its limits

Electrolytes carry an electrical charge in body water and are used to hold fluid in the right compartments, fire nerves and contract muscles. (Permissible Indications Determination)
Across 13 randomised trials, electrolyte supplementation gave an inconsistent picture for muscle cramps. (DOI record)
A Cochrane review of 11 trials found magnesium unlikely to prevent idiopathic or nocturnal cramps in older adults. (DOI record)
Replacing some dietary sodium with potassium reduced stroke and death in an NHMRC-funded trial of 20,995 people. (Randomised controlled trial held in registers/electrolytes.m)
Potassium and blood pressure is U-shaped across 32 trials: more potassium isn't uniformly better. (PubMed 40612568)
Australian law caps potassium chloride at 550 mg per dosage unit outside oral rehydration therapy. (Schedule 1, item 4581)

How it works

Electrolytes are how your body decides where water goes. Sodium and chloride hold fluid in the space outside your cells, potassium does the same job inside them, and the difference between the two is what lets a nerve fire and a muscle contract. Drinking plain water after heavy sweating replaces the water but not the salts, which is the whole reason rehydration products exist. Magnesium and calcium are usually along for the ride in a blend rather than the reason it works.

The Australian rules

There's no Schedule 1 ingredient called "electrolytes". Each salt is listed separately, and they're treated very differently. Sodium chloride (item 4581) is permitted listed with no requirements and no warnings at all. Potassium chloride (item 4094) is the opposite: oral use only, a mandatory kidney and heart warning, and a cap of 550 mg per dosage unit unless the product is oral rehydration therapy. Oral rehydration salts are the one format Australian law specifies a composition for, requiring compliance with the British Pharmacopoeia and with WHO and UNICEF criteria for sodium, potassium, glucose and osmolarity once mixed. Sodium citrate and sodium acid citrate are oral-only as actives. Sodium sulfate carries a laxative warning. Permitted-ingredient status isn't a government endorsement of any product or claim.

Read the instrument: Schedule 1, item 4581.
