L-Lysine is an essential amino acid that plays a critical role in many areas of health, including immune function, collagen production, and fat metabolism. Because the body can’t produce it on its own, L-Lysine must be obtained through diet or supplements. Whether you're looking to support your overall wellness or strengthen a specific area of your health, L-Lysine is a smart and effective choice.
This single-ingredient supplement offers a wide range of benefits, making it one of the most versatile and reliable nutrients in today’s wellness routines. From muscle recovery and calcium absorption to viral support and energy production, L-Lysine is a true multitasker.
One Amino Acid. Multiple Benefits.
L-Lysine is more than just another amino acid—it’s a foundational nutrient your body depends on for daily function and long-term wellness. As a key building block of protein, it supports:
-
Muscle growth & recovery – Helps repair tissue and maintain lean muscle
-
Collagen production – Vital for healthy skin, joints, and connective tissue
-
Calcium absorption – Promotes bone health and reduces calcium loss
-
Fat metabolism – Supports the conversion of fat into energy via L-Carnitine
-
Immune function – Helps defend against viruses and strengthens immune response
-
Energy production – Fuels the cellular energy cycle via acetyl-CoA
No matter your health goals—immune support, athletic performance, skin health, or general wellness—L-Lysine plays an important supporting role.

A 2023 clinical review found that 3–5 grams per day of L-Lysine significantly reduced the recurrence of HSV-related symptoms.
