This is a no-frills electrolyte powder built for hydration — replacing the minerals you lose through sweat during exercise, heat, or low-carb eating. Each half-teaspoon serving gives you 730mg of **Sodium** and 460mg of **Potassium**, and both land right in the range that actually drives fluid balance. These two do most of the rehydration work, and here they're dosed at levels that track the World Health Organization's oral rehydration formula — a real working dose, not a token pinch.

The roughly 3-to-2 sodium-to-potassium split mirrors what your body sheds in sweat, so you're rebuilding both at once instead of just reaching for salt. With zero sugar and no calories, you can mix it to taste and dose it to thirst without anything else coming along for the ride.

Where it falls short is magnesium. At 22mg per serving, you're getting under a quarter of the 100mg where magnesium begins to matter for muscle cramps or sleep, so treat it as a finishing touch on the mineral profile rather than a reason to buy. If magnesium is what you're after, you'll want a dedicated source alongside it.

How to Take It

Best taken in the evening

The Magnesium in it is what pulls this toward the evening. Take it with food — the potassium in it is what makes this kind of product feel nauseating on an empty stomach.

With food
Space it a couple of hours from Iron and Calcium

On the label

Stir a small pinch (1/2 teaspoon or 3 g) into a tall glass or reusable bottle of water. It dissolves fast. Tastes great with a squeeze of fresh lemon or lime over ice.

General guidance based on the ingredients, not a substitute for the label or your doctor.
