Nature’s Harmony® L-Lysine helps in the prevention of recurrent cold sores (fever blisters). This easy-to-swallow capsule comes in a 500 mg dose.
Nature’s Harmony® L-Lysine is an essential amino acid. It must be acquired in the diet because it is not produced by the body. L-Lysine is a necessary building block for protein and is required for the absorption of calcium. It has also been shown to be helpful in bone building.
Ever since I have started to use this, it has reduced the occurrences of cold sores greatly! Price is also good.
