Is Potassium Keto?

The Ingredient Breakdown

When evaluating a supplement for the ketogenic diet, the active ingredient is only half the story. The inactive ingredients, or excipients, are where hidden carbs often lurk. For this specific Potassium supplement, the formulation is surprisingly clean from a low-carb perspective.

The primary ingredient listed is Microcrystalline cellulose. This is essentially refined wood pulp or plant fiber. It is used as a bulking agent to give the pill its size and structure. Crucially, it is not metabolized by the body as a carbohydrate, meaning it has a glycemic index of zero and contains zero net carbs.

We also see Croscarmellose Sodium. This is a derivative of cellulose used as a disintegrant—it helps the pill break down in your stomach so you can absorb the potassium. Like microcrystalline cellulose, it is a fiber-based excipient that does not contribute to your daily carb count. Finally, Vegetable Magnesium Stearate, Stearic Acid, and Silica are used in minute quantities to prevent clumping and ensure smooth manufacturing. None of these ingredients affect ketosis.

Nutritional Value

From a macronutrient standpoint, pure Potassium supplements are virtually devoid of calories, fat, or carbohydrates. The serving size usually provides a specific milligram dosage of the mineral (e.g., 99mg) and nothing else. There is no sugar, no starch, and no protein to speak of.

For a keto dieter, the primary concern is usually keeping net carbs under 20-50 grams per day. Since this supplement contributes 0g to that total, it fits perfectly within the strictest keto limits. It is important to note, however, that while the pill itself is keto-friendly, you should always consult a doctor before starting potassium supplementation, as electrolyte balance is critical on a low-carb diet.
