Is Ultima Replenisher Raspberry Keto?

The Ingredient Breakdown

As a food scientist, I look beyond the marketing claims and dive straight into the formulation. Ultima Replenisher Raspberry is designed as a "clean" electrolyte mix, and the ingredient list reflects that philosophy. The primary sweetener used is Rebaudioside-A (from organic stevia leaf). This is a non-nutritive sweetener, meaning it has a glycemic index of zero and contains no calories, which is the gold standard for keto products. Unlike sucralose or aspartame, it is derived from a plant source, which appeals to many health-conscious consumers.

The flavor profile comes from natural raspberry flavor and a color blend consisting of beet juice and annatto extract. These are natural alternatives to Red 40 or other artificial dyes. While annatto is generally safe, a very small percentage of the population has sensitivities to it, but it poses no threat to ketosis. The electrolyte matrix—magnesium citrate, potassium phosphate, and calcium citrate—is highly bioavailable. Citrate forms are particularly good for absorption and can help prevent the muscle cramps often associated with the initial phases of a ketogenic diet.

Crucially, there are no hidden carbohydrate sources like maltodextrin or dextrose often found in cheaper electrolyte powders. Even the citric acid and malic acid used for tartness are organic acids that do not convert to glucose in the body. The verdict is clear: the formulation is chemically sound for maintaining a state of ketosis.

Nutritional Value

From a nutritional standpoint, Ultima Replenisher Raspberry is virtually a free food regarding macronutrients. A standard serving contains 0 calories, 0g of fat, 0g of carbohydrates, and 0g of protein. For someone tracking their macros strictly to stay under 20g of net carbs per day, this product allows you to replenish electrolytes without using up a single gram of your daily allowance.

The sodium content is moderate (around 55mg), which is beneficial because keto diets often flush out sodium rapidly. However, if you are doing intense exercise or following a strict carnivore or keto protocol, you might actually need to supplement additional salt alongside this drink, as the sodium level is relatively low compared to therapeutic keto hydration drinks like LMNT. However, for general daily maintenance, the balance of potassium and magnesium provided here is excellent for preventing the 'keto flu' without adding any sugar or insulin-spiking ingredients.
