## Overview

L-Lysine 620 mg delivers a potent, vegetarian-friendly amino acid supplement designed to support protein synthesis, healthy stress response, nitrogen balance, and calcium metabolism. With 100 non-GMO, gluten-free capsules, it’s a clean, science-backed formula that helps inhibit glycation, promoting healthy aging and overall vitality for active, health-conscious professionals.

## 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: 🧘🏼‍♀️Essential for Daily Wellness + Improved Hair, Skin, and Nails💅🏽 - 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.
Review: Happy with purchase - Take these daily and am extremely happy with product.

## 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.
