Overview

A potassium bicarbonate capsule from Vitamatic dosed at 1020mg per serving in a 240-capsule bottle, made in the USA and formulated without gluten, aimed at people topping up potassium intake through diet rather than treating a diagnosed deficiency.

Potassium bicarbonate is one of several potassium salts used in supplements and is generally considered gentler on the stomach than potassium chloride. At 240 capsules per bottle this is a larger-format product, likely to suit buyers taking it daily over an extended stretch rather than reordering often. The listing states the compound weight but not elemental potassium per capsule, so comparing it directly against another potassium product means checking the supplement facts panel yourself.

  • 1020mg potassium bicarbonate per serving
  • 240 vegetable capsules per bottle
  • Made in USA
  • Gluten free, non-GMO

Who it's for

Fits adults who want a plain, single-ingredient potassium supplement and prefer a large capsule count over frequent reordering. Not suited to anyone on potassium-affecting medication or with kidney concerns, who should be managing potassium intake with a doctor rather than an over-the-counter capsule.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Large 240-capsule count reduces reorder frequency
  • Made in the USA
  • Gluten free and non-GMO
What to check first
  • Elemental potassium per capsule not stated in the listing
  • No electrolyte blend, just a single ingredient

Performance notes

Potassium bicarbonate dissolves and is absorbed in the gut similarly to other potassium salts, and because it is not paired here with sodium bicarbonate or citrate, it functions as a plain potassium source rather than an electrolyte blend. Gluten-free and non-GMO labeling covers manufacturing claims, not the supplement's effect on the body.
