does it's job

I use it to stop cold sores and does that job wonderfully with just 2 grams daily. My only complain is that it flakes and lumps together easily while stored, which could be solved with a humidity absorption punch or silica bag, it comes with a big one but doesn't seem to be enough.

Nutricost L-Lysine

This L-Lysine is a powder, not granules, so it dissolves more easity. Also, it doesn't have an unpleasant flavor like the other lysines I have tried.

Part of my Daily Supplement Routine

I have been taking a Lysine supplement daily for years now. I feel this has had a positive impact on my health. Lysine is an ingredient that is an essential amino acid. It's a fundamental building block for proteins in our body. It must be obtained through diet or supplementation. Lysine builds proteins that provide structure to our skin, bones, and connective tissues. Lysine helps the body absorb and retain calcium, which is important for maintaining strong bones. Lysine may also help lower levels of the stress. As a building block for protein, it has a quality that makes it good for building muscle. Some evidence suggests it may help maintain muscle mass, particularly in older adults like myself. So lysine has lots of benefits that make it part of my daily supplement routine.

great to mix in my shakes. I add this to my protein shake after working out and the taste is not dominant at all so that is great.
