Life Extension L-Lysine, 620 mg, Essential Amino Acid for Healthy nitrogen Balance, Calcium Metabolism, Stress Response & More, Gluten-Free, Non-GMO, Vegetarian, 100 Capsules

• 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.
