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!

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

This L-Lysine from Source Naturals is very cost-effective and long lasting. Each tablet provides 1000 mg, and the bottle size is large enough to use for a long time. I take it occasionally together with vitamin C, and it has worked well for me. The brand is reliable, the ingredients are simple, and the tablet size is reasonable. Overall, good quality, good value, and something I’ve repurchased from this brand many times.

high -quality supplement

The pill is pretty big but only one is needed per day, which is convenient. Excellent quality and helps keep my immune system strong. Highly recommend!

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.
