A building block for protein, lysine is an essential amino acid, meaning that it cannot be produced by the body alone.

L-Lysine is the form of lysine our bodies can easily make use of and that is why it is important that we find a dietary source.

While meats such as chicken and beef, plus soybeans and pumpkin seeds are sources of L-Lysine, if you feel you may not be getting enough, lysine supplements, such as this Holland & Barrett lysine 1000mg tablet, can help.

Because L-Lysine is found in some of its highest levels in meat and dairy produce, it can be particularly challenging for those who do not eat animal products to naturally consume.

Suitable for vegans and vegetarians, these L lysine supplements should only be purchased by those over 18 years of age.

Why do I need L-Lysine?

Proteins are made from long chains of 20 smaller molecules known as amino acids. Working alongside other amino acids, lysine amino acid helps the body to build protein.

And why do we need protein? Because it makes up the structure of all cells and tissues in our bodies, including muscle tissue, internal organs, tendons, skin, hair and nails. It is pretty important stuff.

A lack of L-Lysine can result in difficulty concentrating, fatigue and irritability. L-lysine for skin and stress

Lysine’s involvement in collagen production leads researchers to think that it may have positive benefits for the skin.

Research suggests that keeping blood L-Lysine levels steady by taking a supplement can even help to reduce the occurrence of cold sores in those prone to the pesky little blighters.

Lysine may also aid those suffering with stress and anxiety. Supplementing with this vital substance appears to reduce levels of cortisol, the stress hormone, and may be particularly helpful for those suffering from high levels of stress.

L-Lysine versus arginine

Not all amino acids are created equal. In fact the amino acid arginine can feed viruses, causing us to fall ill more easily when our immune system is low.

L-Lysine is arginine’s arch enemy because it blocks arginine activity. This process can help us to defend against illnesses such as ear infections. It also supports L-Lysine’s ability to tackle cold sores.

What is l-lysine?

L-lysine is one of the 8 essential amino acids. 


The body cannot produce L-lysine itself, so we need to obtain it through the foods we eat instead. 


L-lysine is the form of lysine our bodies can use. It is commonly found in a range of foods, including legumes, cheese, red meat, pork, eggs, soybeans, and certain fish. 


Amino acids are vital because they combine with other compounds to form protein – a necessary macronutrient.

The importance of l-lysine for vegans and vegetarians

Those following a vegans or vegetarian lifestyle may otherwise find it a challenge to obtain sufficient levels of l-lysine through their diet, since very few plant-based foods contain l-lysine. 


As a result, they might benefit from a daily supplement to help keep their levels adequately topped up. 


Similarly, anyone who is on a restrictive diet or does not enjoy the taste of foods containing l-lysine may want to try incorporating a supplement into their daily routine.
