How to Use It
Most people do not require lysine supplementation. Doctors often suggest that people with recurrent herpes simplex infections take 1,0003,000 mg of lysine per day.
Where to Find It
Brewer’s yeast, legumes, dairy, fish, and meat all contain significant amounts of lysine.
Possible Deficiencies
Most people, including vegans (vegetarians who also avoid dairy and eggs), consume adequate amounts of lysine. However, vegans whose diets contain large amounts of grains and only minimal amounts of beans could become deficient in lysine. Athletes involved in frequent vigorous exercise have increased need for essential amino acids, although most diets meet these increased needs. The essential amino acid requirements of burn patients may exceed the amount of lysine in the diet.
