Solgar L-Proline/L-Lysine (500/500 mg), 90 Tablets - Supports Collagen Production for Healthy Skin & Lips - Essential Amino Acids - Non-GMO, Vegan, Gluten & Dairy Free, Kosher - 90 Servings

Such a wonderful product! My job requires me to do heavy lifting. One day I injured my bicep lifting some product. Wow it hurt for days, even bruising on my bicep appeared. I was told to take these supplements, which I took twice a day [morning/evening]. Within a few days, I was able to use my arm! I could not believe how quickly this healed my injury. Now anytime I get a work or exercise injury, I USE THIS twice a day..I swear by it...!

I seen a lot of complaints about pill size and I’m assuming these individuals have only seen an aspirin all of their life. The pill size is on the larger size but it’s a common “large” pill that is not hard to swallow. I take a BCAA pill that is twice as big. Anyways it’s a good product.

I took this slow at half-dose for weeks then went full. Broke capsule to aide digestion and saw improvement in walking stamina after few weeks.

I like that both amino acids are taken in one pill, rather than two, separate ones. Supposedly, according to Dr. Matthias Rath, both proline and lysine, taken along with vitamin C, are good for the health of the heart. I can't prove it works or not, but it's like an insurance policy, so I take it.

I have taken other Lysine/Proline supplements and felt they were better. I like solgar products and don't have any complaints about any of the others I'm using; however, I think this product could be a bit stronger. The pill is huge, but I didn't feel the product was strong enough.
