Vitacost L-Lysine -- 500 mg - 300 Capsules

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.*. Why choose Vitacost L-Lysine? Supplies 500 mg of L-lysine per single-capsule serving. Contains 300 servings per bottle. Offers exceptional quality at extraordinary value. . About Vitacost.

Capsules won't open
 April 5, 2013
"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."

Use for my cat
 September 9, 2010
"Very easy to open up the pills which is important since I open it and mix it in with his wet food. Very easy and cat doesn't seem to notice the taste mostly compared to the other cat which doesn't get the pill."
