Vimergy L-Lysine – Promotes Healthy Skin, Hair & Nails* – Supports Healthy Metabolism* – Vegan, Non-GMO & Gluten-Free – 270 Capsules
Vimergy

Vimergy L-Lysine – Promotes Healthy Skin, Hair & Nails* – Supports Healthy Metabolism* – Vegan, Non-GMO & Gluten-Free – 270 Capsules

Why we love it
  • Superior three-ingredient formula.
  • Supports healthy skin and metabolism.
  • Vegan and non-GMO certified.
Main Highlights
  • SUPERIOR FORMULA WITH ONLY 3 INGREDIENTS. Lysine is one of the essential amino acids for humans, meaning that it’s necessary for our health but our bodies can’t produce it naturally, so we have to provide it for ourselves through diet and supplementation.* The VIMERGY formula contains only 3 recognizable ingredients and delivers all the lysine you need in one daily capsule.
  • SUPPORTS HEALTHY SKIN + METABOLISM.* The amino acid L-lysine supports production of collagen,* a structural protein that’s important inside the body (ligaments, tendons, and blood vessels), as well as outside the body (skin, hair, and nails). L-lysine is also essential for synthesis of carnitine, which is necessary for healthy fat metabolism.*
  • VEGAN SOURCE OF HIGH-CONCENTRATION LYSINE. Lysine occurs naturally in many of the foods we eat. The primary dietary sources of lysine are animal products — meats and dairy items. If you’re on the vegan path, VIMERGY capsules are your go-to source. Some cereal grains and veggies carry lysine, but only small amounts. A daily capsule of our product offers a full serving of 500mg.
  • EXPERIENCE MIXOLOGY BY VIMERGY. As someone who takes charge of their well being, you decide what your body needs. That’s why it’s essential to incorporate VIMERGY products into your daily routine. Unlike multivitamins, our capsules provide plenty of versatility. They’re a convenient “on the go” form of supplementation that can also be opened and added to smoothies. We provide the ultimate in mixology-based customization to support your health and wellness.
  • PEACE OF MIND CLEAN. VIMERGY is triple third party verified for your peace of mind, and VIMERGY lysine is a natural supplement that comes in a clean capsule format you can trust. Our product is formulated with no gelling agents, no gluten, no corn, no soy, no alcohol, and no unnecessary colors or fillers. We offer a clean vegan supplement that’s non-GMO, gluten-free, and paleo-friendly.
