1,000 mg
It was difficult to find these in 1,000 mg. I have been using the 500 mg and did not like having to take so many pills. Wish they came in capsules!

L-Lysine is crucial for the formation of collagen, a major part of the body's connective tissues. L-Lysine also contributes to energy production when converted to acetyl coenzyme A, one of the principal fuels for the Krebs Cycle.

Good quality lysine at a great price. Helps support immunity and skin health. Tablets are a bit large but easy to swallow with water. Will repurchase. Could be hard to swallow if you have some problems with that

Good as an antiviral
I had run out of Lysine and needed to order more. I use this product when I feel a specific virus coming on and they allow me to avoid taking pharmaceutical drugs.

Helps Clear up Shingles Fast
This is a peer form of L-lysine. Recently I had my first bought with shingles. I started taking this and they cleared up pretty swiftly. It is a large pill so prepare for that. It has great benefit on the immune system and is said to be anti aging.
