Now L-Lysine is a Pharmaceutical Grade essential amino acid.

L-Lysine is an essential amino acid that must be obtained through the diet or through supplementation. Lysine is necessary for the production of all proteins in the body, and is required for the maintenance of the structural proteins collagen and elastin, which form all connective tissue such as skin, tendon, and bone. L-Lysine is also a precursor to L-carnitine, which is needed for fat metabolism and energy production. In addition, L-Lysine may help to support a healthy immune system and proper cardiovascular function.

Suggested Use

Take 1/4 level teaspoon daily.

I mix this with my ascorbic acid to dilute the taste of L-Lysine which i dont really like. This is also part of my cancer protocol and I do it with high dose Vitamin C. This is also the reason why I dont do whole food c. I take almost 10g and above daily. As for my l-lysine, i will add 2 teaspoon in my vit c. theres so many benefits taking l-lysine! I will continue this even after i conquer my cancer! Oh and Dr Linus Pauling mentioned reversal of heart conditions with the combi of L-lysine and Vit C. Please do use my rewards code for👉 5% off 👈 M - I - C - 8 - 6 - 5 - 4 (without the dashes) to support my healing cancer naturally journey and check my other reviews for the other products I use along with this. The products I select are mostly clean without the fillers and additives. Your kind support is greatly appreciated! Thank you!
