What is Lysine supposed to do? Or how does it help?

My trainer suggested I put my OTTB on it.

Thank you.

It's an amino acid and it's supposed to help boost the immune system.

I believe it helps the body process protein more efficiently. It can be a catalyst for weight gain, at least I hope so. I just added it to my horse's diet this month. I used that feedxl site recently to see what was lacking in my horse's diet. I was surprised to see, with all the supplements he was getting, none of them contained adequate levels of lysine.

Lysine is the protein component most often lacking in horse’s diets. From wikipedia:

As an essential amino acid, lysine is not synthesized in animals, hence it must be ingested as lysine or lysine-containing proteins.
L-Lysine is a necessary building block for all protein in the body. L-Lysine plays a major role in calcium absorption; building muscle protein; recovering from surgery or sports injuries; and the body's production of hormones, enzymes, and antibodies.

It a very, very important amino acid that is needed to digest proteins. It's known as the first limiting amino acid as without it the rest can't work.

It is found in Brewers Yeast so adding that to your horses diet will be very beneficial .

All natural horse feed is generally low in Lysine so it does need to get added to the feed to get maximum benefit.

It is usually deficiant in most equine diets. It's very important and even more so for young horses still developing.

Most feeds you buy use cotton seed, which while not a grain (always good to eliminate gran products) is not a good source foe lysine. Soy bean meal is a good sourse for it, but supliments are probably used more.
Humans need lysine too, but meats are our best sources for it (which like omega 3, etc... is easier for us to absorb from meat than from plant sources)
