Free amino acids are single molecules that are no longer attached to a protein chain. Peptide-bound amino acids are still part of short chains (peptides). Both forms can be found in Liquid Amino.

A protein hydrolysate is a protein that has been enzymatically pre-digested into smaller structures. This makes it easier to dissolve in liquids and makes it suitable for liquid formulations such as this supplement.

Essential amino acids must be obtained from external sources, as animals cannot produce them themselves. Non-essential amino acids do not necessarily need to come from food.

The vitamin B6 in this product is present as pyridoxine hydrochloride. This is a commonly used synthetic form of B6 that is highly soluble in water. This form has been chosen due to its good stability in liquid formulations, long shelf life, and suitability for use in clear or flavored drinks.

Vitamin B12 is added in the form of cyanocobalamin. This form is often used in liquid supplements because it offers high stability when exposed to oxygen, light, and acids. Moreover, cyanocobalamin is well-miscible in aqueous solutions and retains its properties during the product's shelf life.
