“L-lysine is an essential amino acid that your body needs. Unfortunately, your body can’t make L-lysine. You must get it from your diet, from eating certain foods. You can get L-lysine from food sources such as beans and legumes, brewer’s yeast, fish and meat and dairy products. Animal proteins like meat, poultry and eggs contain the highest amounts of L-lysine so deficiencies are usually found only among strict vegans.
You can also get L-lysine from taking a supplement”
