I take Lysine at night as it helps me relax along with arginine and Ashwagandha. Source Naturals has been one of my favorite brands for a long time as it has great quality and good ingredients without additives. This size is a good value for money so it is one of my go-to items. Very satisfied with this product so I'll be coming back for more.

Pills are large so be prepared. Since a child I have struggled with cold sores.. lysine has been my saving grace.. I’ve tried it all but these seems to help me if taken regularly.. I still get out breaks when stressed or overheated but they are not as huge and don’t last as long...

Given the small but noticeable improvement of my husband with Long Covid fatigue and shortness of breath, I have to give this stars for assisting with the improvement. I put him on a huge regimen that includes this, NAD+ with Resveratrol, and Glutathione. My theory is that it is mitochondrial damage from Covid. These supplements assist in that repair.

I have one tablet every day for cold sores, I used to get them constantly but I haven’t had one for years, if I eat too many nuts I up the dosage that day or if I get windburn or too much sun on my lips I might get a tingle so I will up the dose to 2 or 3 tablets for a couple of days and the cold sore never appears, this supplement is life changing for those with cold sores A+

Source Naturals has always been my “go to” brand for lysine. Many years ago I developed cold sores and a pharmacist told me to take lysine to help get rid of them. It’s been the most economical remedy. I’ve tried other brands and SN has always been the best because they are easier to swallow than some other brands. The pills are huge horse pills - as I refer to them and the smooth coating on the outside makes them easier to swallow than some other brands. These are also the most effective. I’ve found they work the best. I highly recommend Source Naturals brand.

Source Naturals is a great company for Lysine. The aminos here are clean and effective in my system, and I take them every day. An essential part of muscle recovery as part of my workout regimen. Helps skin heal fast also, after surgery, reduces anxiety by blocking stress response receptors, and a whole host of other benefits.

Be warned these are "horse pills", they're huge pressed powder tablets. Yet if that doesn't bother you like me go ahead. As a vegan there aren't many plant sources besides tofu. The price is right at the perfect dose. A potent anti-viral with other benefits to the body like collagen production & muscle synthesis. Happily take this daily!

Great price, great tub size, great company. L-lysine is not just to protect against coldsors, it is an important supplement for many body functions. Research it and you will be amazed. Best taken with vitamin C.

This on help other amino acid or the root of collagen. I head that to have this one with Stem xcell is so goo for body , havn't try yet and hopefully will be good. Please click "Yes" 👍for my review if its helpful to you. :)
