L-Lysine, 500 mg, 200 Capsules

Lysine appears to help the body absorb calcium, and it plays an important role in the formation of collagen, a substance important for bones and connective tissues including skin, tendons, and cartilage. L-Lysine may slow or stop the growth of viruses! It may stop cold sores (herpes sores) from coming back when taken with vitamin C and bioflavonoids (it blocks enzymes that all virally infected cells secrete and it inhibits the spread of the virus in the body by limiting the effect of weakening the connective tissue). I take it during the cold and flu season and double the dose with any first symptoms. Stay healthy.

L-Lysine is an essential free-form amino acid, which acts as a precursor for other amino acids, including L-carnitine (needed for fat metabolism). L-Lysine is crucial to 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.

The product is wonderful and of high quality. It is very beneficial for me, and I have become used to using it regularly. It is excellent. iHerb’s delivery is also excellent, their quality is outstanding, and they are very reliable and very fast.

L-lysine works to help the oral tissues heal much quicker from aphthous ulcers. Must take a therapeutic dose of 3000 mg a day divided into 3 separate doses, to get enough to help the mouth heal. May take 9000 mg if dealing with canker sores. I learned this from a dentist I once worked with. Has worked every time I've tried it.

nice product for increasing lysine in the body, good company and packaging

Good package size and quality usage - benefits. Please don’t chew the tablet!

I had read that some viruses can be inhibited with lysine so when I feel like I have an infection I take this supplement. It's impossible to know if it works but I can say that I never tested positive for COVID throughout the pandemic. Source Naturals is one of the core brands I buy - I trust their quality, ingredients and I like their bottles/packaging.

L- Lysine can sometimes come in hard tablet form which is quite large and i find challenging to swallow. This brand is in soft veg capsule form and very easy to take. L-Lysine can also be opened and the powder disolved in liquid.

L-Lysine is an essential amino acid that the body cannot produce on its own, meaning it must be obtained through diet or supplementation. It plays a critical role in the body’s production of proteins, enzymes, and hormones, and it is particularly known for its benefits in supporting immune function and promoting the healing of tissues.

Recently, I developed shingles and was prepared for many days of misery from pain and burning. I was pleasantly surprised that by using this product, the rash only blistered a tiny bit, disappeared in less than 4 days and the lingering pain was gone in about 2 weeks. I recommend it
