Lysine is one of the 20 amino acids that are found in the body system and also known as building block of protein. t is water soluble and belongs to the group of 8 essential amino acids

It helps in calcium absorption and nitrogen balancing. It also boosts immunity as it has anti viral properties and also by helping in the production of antibodies against infections. It plays an important role in maintaining the production of hormones, enzymes and collagen.

As it comes in essential amino acid group, the body can’t produce it, but should be supplied externally.

Good sources of lysine are high-protein foods such as eggs, meat (specifically red meat, lamb, pork, and poultry),soy, beans and peas, pulses, cheese (particularly Parmesan), and certain fish (such as cod and sardines).
