L-lysine is a versatile essential amino acid that the body cannot produce or can only produce in insufficient quantities. It can mainly be found in protein-rich foods such as various dairy products, meat, and eggs.

L-lysine can easily be replaced by a balanced diet and good quality nutrients, but in certain cases, such as for those following a vegan lifestyle, it may be necessary to source it from other means besides meals.

The BioTechUSA L-Lysine dietary supplement capsule can help with this. Thanks to the capsule form, it is easy to portion and take with you anywhere during the day.

L-lysine contains safe, carefully selected ingredients.
