Keto & Fasting Electrolytes — 120 Capsules, Magnesium, Potassium and Sodium Chloride
- Potassium contributes to normal muscle function and the maintenance of normal blood pressure
- 120 capsules — a 40-day supply at three capsules daily
Electrolytes Without the Sugar, the Flavouring, or the Mixing
When you cut carbohydrates or extend your fasting window, your mineral intake naturally shifts. Keto & Fasting Electrolytes delivers a clean electrolyte blend — sodium, potassium and magnesium — in a plain capsule with no sweeteners, no flavourings and no calories. Take three capsules with water and carry on with your day.

Built Around the Keto and Fasting Routine
Electrolyte powders and drinks often come with sweeteners, flavourings or calories — none of which fit neatly into a clean fast. These capsules are a different format: no taste, no sweetness, nothing to measure or mix. Three capsules with a large glass of water is a straightforward way to keep electrolytes part of a daily low-carb or fasting routine, whether taken during an eating window or at any point in the day.
Why Electrolytes Matter on Low-Carb Diets
Carbohydrate restriction reduces glycogen stores, which in turn lowers the amount of water — and minerals — retained by the body. Sodium, potassium and magnesium are the three minerals most commonly considered in ketogenic and fasting nutrition. Including them as part of a daily supplement routine is a practical step for people committed to a low-carb or time-restricted eating lifestyle.
Taking It Every Day
Three capsules daily with a large glass of water — on training days and rest days alike. The capsule format is easy to carry: gym bag, desk drawer, travel case. The 120-capsule bottle means 40 days per order, with enough to keep a routine going without having to reorder constantly.
Inside the Formula
Potassium Chloride — Providing 300mg potassium per daily serving. Potassium contributes to normal muscle function and to the maintenance of normal blood pressure.
Magnesium Citrate (Buffered) — A well-absorbed form of magnesium used in electrolyte supplementation, included alongside potassium because the two minerals are commonly considered together in low-carb and fasting nutrition.
Sodium Chloride — Providing sodium and chloride in a single compound. Chloride contributes to normal digestion by production of hydrochloric acid in the stomach. Sodium is a standard electrolyte component included alongside potassium and magnesium.

Frequently Asked Questions
Can I take these capsules while fasting?
Yes — these capsules contain no calories, sweeteners or flavourings. They can be taken with water during a fasting window. If you prefer to take supplements during your eating window, that works equally well.
How many capsules should I take each day?
Adults take three capsules daily with a large glass of water. Do not exceed the recommended dose.
Are these suitable for vegans?
Yes — the capsule shell is hydroxypropyl methylcellulose (HPMC), a plant-derived alternative to gelatin. All ingredients are vegan-suitable.
Is this suitable for people with kidney conditions?
Not recommended for those with kidney disease, low pulse rate, hyperkalaemia or those taking medications that affect potassium levels. Consult your GP before use if you are on any medication or under medical supervision.
Why we formulated it this way
Electrolyte products are usually flavoured drink mixes — sweeteners, powders, scoops. We built this one differently, as a plain capsule, and each ingredient has a reason:
-
Potassium Chloride, providing 300mg potassium per daily serving (15% NRV) — chosen as the primary mineral because at this intake it clears the "source of" threshold for its authorised claims. Potassium contributes to normal functioning of the nervous system and to the maintenance of normal blood pressure.
-
Magnesium Citrate (buffered) — a well-absorbed citrate form, included alongside potassium because the two minerals are commonly considered together in low-carb and fasting nutrition. We're still finalising the supplier's confirmed elemental-magnesium figure for this batch, so we're not making specific magnesium claims here until that's verified — see the honesty note below.
-
Sodium Chloride — supplies sodium and chloride in one compound. Chloride contributes to normal digestion by production of hydrochloric acid in the stomach.
Three capsules, once daily, 120 capsules per bottle — a 40-day supply. No mixing, no sweeteners, nothing to break a fast.
What the evidence does — and doesn't — say
Here's the honest picture rather than the marketing one. Carbohydrate restriction and extended fasting do reduce glycogen-bound water and shift fluid/mineral balance — that's established physiology, not a product claim. What we can say under UK law sits specifically with the minerals at their tested doses: Potassium contributes to normal functioning of the nervous system and to the maintenance of normal blood pressure, and Chloride contributes to normal digestion through hydrochloric acid production in the stomach. What we won't say: that this capsule "rehydrates" you, prevents cramps, or replaces the fluid itself — plain water does that job, and no food supplement can lawfully claim otherwise. Minerals support normal bodily functions; they are not a treatment for symptoms of low-carb or fasting adaptation.
Questions customers actually ask
Can I take these during a fasting window? Yes — the capsules contain no calories, sweeteners or flavourings, so they don't technically break a fast. Take with water whenever suits your routine.
Do I need these if I already take a magnesium supplement? If you're already supplementing magnesium elsewhere, check your combined daily total — this product isn't designed to be your sole magnesium source, it's a balanced mineral set aimed at potassium, sodium and magnesium together.
Are they vegan? Yes — the capsule shell is HPMC (plant-derived, not gelatin), and all ingredients are vegan-suitable.
Can I take these alongside electrolyte drinks or sports hydration products? You can, but add up your total mineral intake across products — particularly potassium — rather than treating each product in isolation.
Will this replace water or rehydration drinks? No. Minerals support normal function; fluid replacement still needs to come from drinking water. This product is a mineral top-up, not a hydration substitute.
Who this is for — and who it isn't
For adults following a ketogenic, low-carb or intermittent fasting routine who want a sweetener-free, capsule-format way to keep sodium, potassium and magnesium as part of their daily intake. Not for you if: you have kidney disease, a low pulse rate, hyperkalaemia, or you're taking medication that affects potassium levels — speak to your GP first, as this product is specifically not recommended for those conditions. Also not suitable for children or pregnant/breastfeeding women. If you're newly restricting carbohydrates and experiencing persistent symptoms, that's worth raising with a GP or dietitian rather than treating as a supplement question alone.
