Lysine is an essential component of all proteins and works with other essential amino acids to maintain growth, lean body mass, and the body's store of nitrogen. Lysine acts as a precursor for several other amino acids, including L-Citrulline (needed for normal protein metabolism) and L-carnitine (needed for fat metabolism). Lysine is crucial for the formation of collagen, a major part of the body's connective tissues and appears to help the body absorb and conserve calcium and may reduce its excretion. Lysine contributes to energy production when converted to acetyl coenzyme A, one of the principal fuels for the Krebs cycle. Lysine is needed for growth and to help maintain nitrogen balance in the body. L-lysine has many other functions in the body because it is incorporated into many proteins, which are used by the body for a variety of purposes. Lysine supports a healthy immune system. Like all NutraBio products, our L-Lysine features a fully transparent label with no hidden ingredients, no fillers, or other unnecessary ingredients. Review: Back in the mid 90s, I took lysine for about 2 years, 500mg/day, and noticed that I stopped getting fever blisters. No outbreaks at all. And I used to get honkers. So big that my husband would give them names, "Oh, are you and Chuck going out for awhile?" Funny. After I didn't have them for a few years, I laid off for a couple of years, taking it now and then, and still no outbreaks. Then in the last 5 years, I got maybe 4, not even one a year, but they never came to fruition: just a bump for a day or two, then went away. Then a couple of months ago, I got some to give to the stray kittens for their eye infections, so we started taking it again. We put it in our breakfast mix (cottage cheese and flax seed oil ala Budwig). It's tasteless, don't even know it's there. There is some evidence that cancer can be based in a virus and lysine is definitely anti-viral. It's so easy to take and no evidence that it can hurt, so it's again part of our routine and we're very glad to have it back! The kittens were very healthy when we took them to the no-kill shelter :) Review: I use L-Lysine, in general, as an immune booster for my cats, and for other cats in the rescue I volunteer for. It works! This is my favorite L-Lysine product because of level of quality, and because of the fine grain that this product comes in. We had always used this brand, but last time I tried the NOW brand L-Lysine powder because I like trust that brand as well as this one, and their price was lower. It was a mistake. That stuff was SO thickly grained. I won't ever deviate from this NutraBio brand again, because this is the only brand that has the L-Lysine powder as an actual very fine grain powder. Other brands have a much rougher grain, and it doesn't stick to the kibbles as well. I use this product every day, sprinkled onto my cats dry food. Because it is as fine as dust, it sticks really well to my cat's food and therefore they get more of it per bite, and I don't end up wasting any because it doesn't stick and falls to the bottom of the bowl. It's worth the extra price! ## Features - ESSENTIAL AMINO ACID - Lysine is an essential amino acid, meaning it must be obtained through diet or with supplements.

It easily mixes with wet food and doesn't put off the cats from the food. Would recommend. ## Frequently Bought Together - NutraBio L-Lysine Powder - Pure Grade Amino Acid - 500 Grams - Essential Amino Acid - Non-GMO - Gluten-Free - Vegan - Vitamin C Powder Pure Ascorbic Acid Soluble Fine Non GMO Crystals – Promotes Healthy Immune System and Cell Protection – Powerful Antioxidant - 1 Kilogram (2.2 Lbs) - Non Acidic Vitamin C Powder Sodium Ascorbate Non GMO Soluble Fine Crystals - Healthy Immune System, Antioxidant and Cell Protection, 1 Kilogram (2.2 lbs, 35.3 Ounces) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/255644432-l-lysine-powder-500-grams](https://www.desertcart.co.uk/products/255644432-l-lysine-powder-500-grams) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
