Preventing cold sores
Since I started drinking this, I haven’t caught any colds. I used to catch colds frequently when working out, but after taking this, I’ve been fine. It may be a placebo effect, yet I continue taking it.

I find this supplement very effective. I take 10g every morning and an extra 10g when stressed. Since using it, I rarely catch colds and have yet to contract the coronavirus. I will keep using it, although the price has increased significantly.
