How it helps

What is L Lysine ?

L Lysine is an essential amino acid. It's found in red meats such as beef and in much lower quantities in most vegetables.

What does L Lysine do ?

Like all amino acids it functions as a building block for proteins. It also plays a role in bone growth by aiding calcium absorption and it also helps collagen integrity. Doctors and nutritionists often recommend Lysine supplements during an attack of cold sores or to control other herpes simplex related infections, since it appears to reduce and help the replication of the herpes virus.

Service rating : timely delivery
Product : I only say that because the packaging is absolutely outrageously wasteful. The plastic contained is twice the size that is necessary. IT defies me as to why this should be necessary to be so wasteful. The product itself is fine.
