Amino acids are the building blocks of proteins. They naturally occur in foods such as meat, fish, eggs, dairy, legumes and grains.
L-lysine is an essential amino acid. Essential amino acids must be obtained through food or supplements, unlike non-essential amino acids.
Essential amino acids, like L-lysine, must be obtained through food or supplements. Non-essential amino acids are produced in the body from other building materials.
L-lysine naturally occurs in foods such as meat, fish, eggs, dairy, and legumes.
Free-form means the amino acid is present in its free, unbound form, not attached to other amino acids in a protein chain.
L-lysine HCl is the form in which L-lysine is bound to hydrochloric acid. This salt form is often used in supplements because it keeps the amino acid stable.
According to the manufacturer's instructions, the capsule is to be taken on an empty stomach with water. This aligns with the free-form property of the amino acid, where it is taken separately from other amino acids from food, instead of together with the amino acids that are consumed during a protein-rich meal.
