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

Thanks for your feedback!

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.

Thanks for your feedback!
