L-Lysine 1000 mg Tablets is part of the premium amino acid range. It is an essential amino acid found in the muscle tissue and is also a supplement that is popular with people for seasonal support. Amino acids are the building blocks of protein and are needed in several internal functions of the body. They are classified as "essential" or "non-essential", with essential amino acids meaning they cannot be manufactured by the body and must be supplied in the diet to maintain good all-round health. A suboptimal intake of the essential amino acids increases the body's need for the non-essential amino acids either through diet or supplementation. Foods that increase amino acid intake are meat, beans, cheese and eggs. L-Lysine is an essential amino acid and eating a healthy and balanced diet should help achieve good levels of the amino acids we need. However, taking a supplement may be a convenient way to achieve and maintain our intake of L-Lysine. - Essential amino acid that cannot be made by the body - Amino acids form the basis for protein - Vegan, Vegetarian, Kosher and Gluten Free - Free from sugar, salt and starch - No Dairy, Lactose, Soy, Wheat or Yeast To use: 1 tablet to be taken daily.
