definitely works for viruses. Love that I don't have to ingest plastic capsules...they are not good for the digestive system.

Our vet recommended giving our pets (dogs and cats) L-Lysine to support immune function. Life Extension's powder scores very high, and it's easy to scoop with a 1/4 tsp measuring spoon.

I take this to help with my cell membranes, but don't know if it works for me or not.
