Your dosing guide

How to get the most out of it.

1000mg
Sodium
as sodium chloride
250mg
Potassium
as potassium citrate
75mg
Magnesium
as magnesium citrate
Mixing
One scoop, 750ml.

Stir or shake until fully dissolved. Cold water works best. The Mango-Passionfruit comes through cleanest at fridge temperature.

New to high-sodium electrolytes? Start with half a scoop in 750ml for the first week. Most people work up to a full serve within a few days once the taste is dialled.

How many a day?
One serve a day.

That's the maximum: one serve is 1000 mg sodium. If you're sweating heavily or deep in a fasting window, time it around your longest or hottest session.

Rawstone is a formulated supplementary sports food, not a medicine. Not suitable for children under 15 years of age or pregnant women: should only be used under medical or dietetic supervision. If you have a health condition, check with your doctor first.

Timing

When it works hardest.

Sodium isn't just a gym thing. Here's when a serve earns its keep.

Your situation

Which one's you?

Keto or low-carb

Cutting carbs makes your kidneys flush more sodium. The headaches, fatigue and cramps people call the low-carb flu often come from that mineral loss. One serve puts a meaningful amount back.

Intermittent fasting

Many people hit a dip around hour 14 to 16 of a fast: low energy, light head, flat mood. That is often low sodium and potassium. A serve puts them back without breaking the fast.

Sport and heavy training

Most sports drinks deliver 200 to 400mg of sodium per serve. An hour of hard, sweaty training can cost you more than a gram, so a single serve of those barely dents it. Rawstone's 1000mg covers a real session.

Daily clean hydration

Even if you spend the day at a desk, running on plain water and coffee can leave you low on sodium. One serve covers the gap with no sugar and nothing artificial.

What's in it

Mineral forms matter.

The form a mineral comes in changes how it dissolves and how it tastes.

Potassium, as citrate
Soluble, clean, no metallic edge.

The cheap form, potassium chloride, has a metallic bitterness, which is why brands either mask it with sugar or live with the off-taste. Potassium citrate dissolves cleanly and tastes clean. It's part of why Rawstone tastes the way it does.

Magnesium, as citrate
A source of magnesium. Fully soluble.

Cheaper products use magnesium oxide, which barely dissolves in water. Magnesium citrate dissolves fully. At 75mg per serve, Rawstone is a source of magnesium alongside the sodium and potassium.

Sweetened with
Reb M. No bitter aftertaste.

If you haven't heard of Reb M: most sugar-free drinks are sweetened with stevia, and the common cheap grade (called Reb A) is what leaves that bitter aftertaste. Reb M comes from the same plant but tastes clean. It costs more, which is why most brands don't use it. No sugar, no artificial sweeteners.

Clean label
Zero sugar. Full doses.

A lot of electrolyte powders are sweetened with several grams of sugar. Ours has none, and the full sodium, potassium and magnesium dose is printed on the label.
