Offers support during times of mental anxiety and stress.*. What is L-lysine? L-lysine is an essential amino acid meaning the body cannot synthesize it on its own but it must be obtained through diet (mainly from foods high in protein). L-lysine is required for many body functions that support skin bones collagen and elastin.* It’s also important for normal growth and development.*. L-lysine is converted in the body to acetyl CoA which is a critical part of metabolizing carbohydrates for energy.* Lysine is also a precursor to carnitine which helps transport fatty acids into the mitochondria where they can be used for energy or other functions.*. Lysine has an antagonistic relationship with L-arginine making it useful in the reduction of arginine levels.*. How does L-lysine support health? Supports immune system function.*. May support a healthy cardiovascular system.*. Supports absorption of calcium from the digestive tract making it more available for biological functions.*. Since L-lysine is single nutrient it’s often combined with other herbs or amino acids to obtain complementary effects such as immune system support or helping to reduce mental stress and anxiety or cardiovascular benefits.*.

"I only buy my L-Lysine from Vitacost!! I cannot swallow pill form so they have the Capsules and I love the prices and it gets to my house so quick. I have never had a problem and I have been buying them here for over 15 years."
"I use three of these L-lysine capsules and three of the arginine capsules before my workouts. And the same on an empty stomach in the mornings. Also the carnatine capsules with meals. A must for body building. To prep for shows, I use all three of the mentioned aminos on an empty stomach in between all my 5 meals and at bedtime. Along with other body building supplements and lots of protein. I need all the help I can get to build and keep muscle size and maintain low body fat. Vitacost brand are the best value."
"I've been using these capsules for years for my cats. I open them and mix them with their canned food. However, the recent batches have had capsules that are nearly impossible to open. I can't open them and have to get my husband to pry them open - sometimes with a knife. The lysine still seems effective, but I won't be purchasing these again."
