Jarrow Formulas L-Lysine 500 mg, Dietary Supplement, Amino Acid for Protein Synthesis and Healthy Tissue Support, 100 Capsules, 100 Day Supply

I am extremely satisfied with this product! The quality is outstanding, and it exceeded my expectations. It works exactly as described, and the packaging was secure. Delivery was fast, and the customer service was great. I would definitely purchase again and recommend it to others.

Consistent quality from Jarrow; take this every day; it works!

This lysine works great. No side effects.

Not much else I can say about a vitamin supplement.

These are easy-to-swallow capsules! I normally can't swallow large pills ('horse' pills), but these are light and slide down easily! Works great for open soars in the mouth (herpes). No side effects. It's an amino acid. I've tried the powders with Vit C, but don't care for the taste. Water works with these, but anything thicker, like juice or milk, makes it feel like you're not swallowing anything at all. I'm a petite size, so 1,000 mg (2 capsules) work for me on a daily basis, if needed. My Dr suggested this based on comments from other patients. When I feel the tingling of a soar (the sign that a soar is coming), I take 3,000 mg every day for 3 days, then back to 1,000 mg for a couple days just to be sure it's gone. The soar doesn't start! This is natural, and I believe it's better than taking a prescribed medication, like Acyclovir.

The vet recommended Lysine for our cat that appeared to have itchy skin. It seems to work -- just a little bit in his wet food. These capsules are easy to open and pour out the powder... I get about 3-4 doses from each capsule for the cat. It would be nice to just buy Lysine a powder form, but this is the next best thing.

I got these for cold-sores and cankersores! They are larger but they go down easily!! I take 2, 3x a day with an active cold-sore every day until 1 day after and my cold-sore NEVER formed but I could feel it trying to bust through every day! I really like these and plan to ALWAYS have a bottle on hand!!!

I have been taking these for maybe 9 months and haven’t had one cold sore yet! I get cold sores when I’m stressed or with weather changes and have had them every few mo this since I was little. These things work.
