Carlson L-Lysine Powder, 960 mg, Free-Form Amino Acid, 3.53 oz (100 g) | Tissue Health; Muscle Development

Carlson is one of the best supplement brands, in my experience, and this is pure l-lysine (an amino acid), with no fillers. We've been using it as part of the "Pauling Protocol" for ensuring cardiovascular health (l-lysine, l-proline, and Vitamin C). It's also TERRIFIC for immune support and can help speed recovery from colds, shortening their duration & possibly even suppressing them completely (MY OPINION & EXPERIENCE). L-lysine helps with so many things; muscle retention, skin health, and more. It can even help treat or even suppress cold sore breakouts at an 8 gram dose; can't remember the dosage schedule, but you can look it up online. This is not a listed benefit, but I find it helps me concentrate better when I have a long project to tackle. If I start feeling mentally fatigued, I'll take a 2 gram dose with some Vitamin C and within about 20 minutes, I'm back on my game. Just FYI, I have a very mild case of inattentive-type ADD, so this is a TERRIFIC aid for that issue. Focus drifts? Lysine to the rescue. I do not know why this works, I only know that it does (cannot find any substantiation for this effect in any of the medical literature). We also sprinkle a little bit of this on our cat's food about once a month or as needed for improving his immunity and general health. You can mix this with a small amount of water or juice --OR-- my favorite method is to fill my own capsules by using Now Foods Veg-Capsules Double "00" Empty Capsules, 250-Count and a capsule filler like this Cap-M-Quik + Tamper, Capsule Filling Filler Machine, size 00 . Here's a very good resource on amino acids to teach you more: The Healing Nutrients Within . Amazon's Subscribe & Save price is excellent; highly recommended!

Love this product. I cannot tolerate L-carnitine, so I use this with L-methionine for skin and muscle health (great for anti-aging benefits.) The body converts L-lysine and L-methionine into L-carnitine, so when I began to have allergic reactions to L-carnitine, even in it's pure powder form, I replaced it with the precursor amino acids with no issues. This is pure and has no fillers.

Have been using this brand for long time. I give it to my cats, mix it into their food. Instead buying the expensive one from the pet store or Vet's office, it's the exact same thing. Got that tip from the person I adopted them from. Keeping my babies healthy. It's a fair price. I usually get it from the Health Food store but they were out.

I tend to get canker sores when I'm stressed out or when I eat highly acidic foods. My dentist recommended that when I feel one coming on, I should take lysine, and he also prescribed a paste to put on the area before bed time. So as soon as I know I'm getting one, I put one scoop of this lysine powder into some juice, twice a day, and it works wonders. Granted, I'm using the paste as well and by using both, I can avoid the canker sore altogether - by the next morning, it's gone! Without the paste, just using the lysine, it means the canker sore is gone in a couple of days, so it's not like this is a miracle drug on its own but definitely worth having in your arsenal if canker sores are an issue for you. It is ridiculous that it took me so long to find out about this but glad I know now. I also hate swallowing pills so I really love that this is a powder that dissolves in juice easily so it's easy to swig it down. It doesn't taste great, but not terrible. Sort of adds a "plastic-y" taste to apple juice. So worth it though to avoid pesky canker sores that used to cause agony for 7-10 days at a time!

Slightly bitter taste, I add it to daily collagen and fruit drinks which disguises flavor. Excellent product! Amazing for skin :) Also if you ever have a cold sore, this works fast.

Love this stuff, buying my 5th container of it now! I mix this into orange juice every morning and it helps prevent any cold sores that I've notoriously gotten since I was a child. I haven't gotten one in about a year and I think this supplement has been a huge help in that! I've also noticed it's been helping my acne prone skin! One container lasts me about 2-3 months so this is a very affordable supplement.

This L-Lysine is the perfect amino acid to help with cognitive and weight loss. It is a great value for the money, the texture is little pellets that dissolve perfectly, small size container but lasts for a long time. I will continue using this Carlson product with many others.

I have used this product for years! It is the best for keeping me from getting cankor sores or if I should happen to get a sore, it will go away quicker than any other thing I have ever used. I highly recommend it!
