L-Lysine 620 mg, 100 capsules

Lysine is an essential amino acid necessary for growth and to help maintain nitrogen balance in the body. (Essential amino acids cannot be made in the body and must be supplied by diet or supplements.)Lysine appears to help the body absorb and conserve calcium.139 Lysine has many functions in the body because it is incorporated into many proteins, which are used for a variety of purposes.

Most people, including vegans (vegetarians who 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 lysine deficient.

Athletes involved in frequent vigorous exercise have an 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.


  • L-Lysine Helps With Better Calcium Absorption

  • May Help Reduce Anxiety And Other Psychological Symptoms
