My reaction to bug bites is sometimes extreme, but no longer. As a bonus the Lysine seems to have solved the arthritis irritation in my wrist. Perfect, thank you. M
I had been using the house brand of Lysine for a while. It worked somewhat. I was surprised how much more effective this brand is! I will be staying with Thorne brand. Thank you for making a quality product.
Using Lysine, as part of 4 or 5 supplements a biochemist recommended to me; I have excellent success when used at the first signs of a respiratory illness. This has worked for my family for over 40 yrs. Under her direction I only use the best, i. e. Thorne. A. Hugger Smith DDS
