Baseline powder is a combination of minerals in powder form, often based on bicarbonate and/or citrate compounds. You mix it with water to make a mildly alkaline drink.

Both are mineral salts. Bicarbonate is a base form, while citrate is an organic acid residue of citric acid. They are often combined in supplements for their solubility and ease of use.

Potassium bicarbonate is a salt of potassium and bicarbonate, a basic mineral. Potassium citrate is a compound of potassium with citric acid. Both provide potassium, but have a different chemical structure and dissolving behavior in water.

By combining different salt forms, the solubility and tolerability of the powder are optimized. Bicarbonate provides an alkaline character in solution, while citrate forms often dissolve well and have a neutral taste.

Magnesium citrate is an organically bound form of magnesium, in which magnesium is bound to citric acid. It is often used in supplements due to its good solubility in water.

Sodium bicarbonate is better known as baking soda. In supplement form, it is used as a source of sodium and bicarbonate. It has a mildly alkaline character.
