L-lysine supplement for GBM?

Hi All,

Has anyone used L-lysine as part of their cocktail?

We are taking a look at it as a possible way to interfere with arginine. There was a recent study that suggested the amino acid arginine could be used as a fuel source by GBM, and arginine has been implicated in other cancers, as well. https://www.nature.com/articles/s41419-018-1195-4

If I understand correctly, L-lysine may compete with arginine for entry into cells -- thus potentially decreasing the amount of available arginine for fuel.

I read that L-lysine is more commonly used to treat cold sores and to assist in calcium supplementation. Has anyone taken it, and if so at what dose? Any side effects or drug interactions to be aware of? 


Thanks so much!!
