## Overview

Life Extension L-Lysine delivers 620 mg of an essential amino acid per vegetarian capsule, supporting healthy stress response, nitrogen balance, calcium metabolism, and anti-glycation effects to promote graceful aging. This non-GMO, gluten-free formula is made in the USA and designed for professionals seeking clean, science-backed supplementation to enhance recovery, immunity, and overall vitality.

## Description

L-lysine is an essential amino acid, which your body cannot make on its own. L-lysine promotes healthy nitrogen balance and calcium metabolism. In addition, it helps promote a healthy stress response and inhibits glycation reactions, which in turn promotes healthy aging. L-Lysine contains 100 vegetarian capsules, enough for a 33-day to 100-day supply, depending on your preferred dosage. This gluten-free formula is made with non-GMO ingredients.

Review: I'm so glad this comes in capsules—they’re way easier to take than those massive oval tablets from the chemist. Even better, I managed to find it on special!
Review: I’ve been taking this L-Lysine supplement daily, and it’s a reliable, high-quality option—non-GMO, vegetarian, and easy to mix with my other supplements. It effectively supports stress response, nitrogen balance, and metabolism. Most noticeably, it has strengthened my skin, hair, and nails, leading to faster hair growth, thicker strands, more resilient skin, and improved overall appearance. It has also enhanced my immunity (fewer minor illnesses) and boosted physical energy and recovery.

## Features

- The little amino that could—Lysine is one of the building blocks of protein. It’s also an essential amino acid, which means your body can’t make lysine on its own. But not everybody gets enough lysine in their diet (this is especially true for athletes).
- Shrug off stress—This helpful amino acid encourages your body’s healthy response to stress. It also helps you maintain a healthy nitrogen balance, lean body mass, and promotes healthy calcium metabolism.
- Aging the healthy way—Lysine helps inhibit glycation, a biochemical reaction where lipids and proteins bind to sugars in non-functional ways. Glycation contributes to the physiological effects of aging, so lysine can help you age gracefully!
- Ingredients matter—We use the finest raw ingredients with the quality and purity you deserve. The majority of our products are non-GMO, gluten-free and manufactured in the USA—and a Certificate of Analysis is available for every one.
- Live your healthiest life—We believe the answers to a healthier life are in reach, and that scientific research is the key to getting there. That’s why so many of our formulas feature specific ingredients and amounts based on scientific studies.

*by R***S on 14 October 2020*

So, a little back story on myself. I have a love/hate relationship with all things citric. I cant get enough of lemonade, orange juice, grapefruit, you get it. Only problem is i have a low tolerance for citric acid, the stuff causes rather painful boils to rupture in my mouth (canker sores) within hours of drinking something especially potent, such as a glass of fresh squeezed lemonade. This condition is largely unresearched, and set in during my early teen years. I suffered for several years, basically swearing off of anything with citric acid being one of the top 5 ingredients. I didnt do well. I relapsed a lot, so i would just kinda keep a tab in my head, "ok thats 1 mtn dew, i can risk 3 more this week before I can't eat for a few days due to 3 or 4 lesions forming around my tongue or lips making even speaking painful.....screw it, going for broke". Around 17, my older sister heard me complaining about this and she told me she took L-Lysine tablets to help with her lesser version of what I now assume is a genetic hand-me-down. Lysine heals the soft tissues in your body you see, and I soon discovered if i took them, it had a dramatic effect on my healing rate, but if i took them regularly, I'd pretty well be canker sore free. Ive tried 2 or 3 brands of lysine capsules over the last decade. My last go to must've swapped something out as I was noticing a marked decrease in effectiveness. So I tried Life Extension. It was a smidge pricier, but whatever if i can enjoy my citrus drinks. As a side note i now work for a large amino acid producer, who used to make lysine(since discontinued) and now have a sort of intimate awareness of the process. Anyway, there are grades of product meant for different purposes: pharmaceutical, food additive, veterinary, etc. This particular brand must use a higher grade stock in their capsules, I can feel a sore coming on, take 1 capsule, and the next morning the sore has disappeared. I haven't had any sores since i purchased this stuff. I dont take it daily either, only when i feel one about to emerge, and the effect seems to stick around for a while. My previous brand of choice was unable to achieve this level of healing or in such a time frame. Truly top grade stuff. You guys have me for life, or atleast till you sell out and swap to a lower grade amino acid. Please don't.
