5 Important Health Benefits of Lysine

Lysine an amnio acid

Lysine is one of the nine essential amino acids that your body needs to make protein – you can only get it through your diet or supplements.

Food sources of lysine include quinoa, lentils, kale as well as meat, cheese, eggs and fish.

Lysine impacts overall health through its role in forming collagen, hormones and immune cells.

Let's take a look at the five important health benefits of Lysine.


If you are getting regular cold sore flare-ups, it could be a sign you’re not getting enough lysine. It is a natural therapy for preventing recurring cold sores caused by the herpes simplex virus. Lysine has been shown to reduce the severity and healing time.


Snacking on protein rich foods such as Greek yogurt or hummus is a fantastic way to keep blood sugar steady – thanks in part to lysine found in these foods!


As an essential amino acid, lysine is a key nutrient in immune support. It is needed to help make and activate T Cells and cytokines for immune system activation – lots of research in to its role in fighting viruses.


Keeping your lysine intake up may prevent the dangerous build up of plaque in your arteries. It has been shown to work on reducing bad cholesterol from sticking to artery walls as well as being key in the production of l-carnitine which is a nutrient which helps fuel energy production in cardiac muscle.


Lysine is one of the secrets to maximise the body’s production of collagen which is a protein that makes up and helps repair tissue in the skin, bones and joints. Collagen production slows down as we age causing joint pain. In menopause, skin quickly loses collagen and studies show that women’s skin loses about 30% of its collagen during the first 5 years of menopause resulting in loosening and wrinkling of the skin.

Lots of great reasons to think about lysine. If you want a good boost of this key nutrient, look at supplementation. Check out our Lysine supplements here
