Description
PURE Electrolyte Capsules, known to most athletes as salt caps, are a way of taking sodium and the other sweat electrolytes without adding any carbohydrate or flavour to your bottle. That matters when you are already fuelling from gels or a drink mix and simply need more salt, or when conditions turn hot and your sweat rate climbs. Each capsule carries sodium from sodium chloride plus potassium, magnesium and calcium citrates, with vitamin D3. The bottle holds 80 capsules.
Product Strengths
- Helps relieve muscle cramps and reduce how often they occur.
- Helps relieve the symptoms of dehydration.
- Helps maintain and restore body electrolyte balance.
- Aids post-exercise recovery.
- A serving of 2 capsules provides 330 mg of sodium and 114.8 mg of potassium.
- All four sweat electrolytes in one capsule: sodium, potassium, magnesium and calcium.
- Vitamin D3 included.
- Tasteless and carbohydrate free, so it will not clash with whatever is already in your bottle.
- 80 capsules per bottle.
Suitable For / Not Suitable For
Suitable for: Active adults and athletes.
Not suitable for: Anyone with an allergy to the listed ingredients; Pregnant or breastfeeding women, unless advised by a health professional; Vegans and vegetarians, because it contains lanolin.

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?
How the forms compare
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.
