Lysine is considered an essential amino acid, a component of protein that our body cannot make. Many people use it to assist healing of herpes sores. With other supplements, it can also be effective in the treatment of ParkinsonÄôs disease, AlzheimerÄôs and hypothyroidism.
Lysine can be used topically or taken internally as a free-form amino acid or eaten as natural food sources. Free-form means that the individual amino acid has been isolated from a protein source and is purely a single amino acid. Free-form amino acids are used specifically in righting deficiencies.
