I have been taking a different lysine product (a thousand mg each day). I do know that I’ve not had a chilly sore since taking these. Also if you’re having an outbreak then be conscious of the L-Arginine to L-Lysine ratio in your food plan you may look on-line for charts with the ratio of L-Lysine to L-Arginine in several meals. That is THE ONLY lysine product I take advantage of on a regular basis
