Offers support during times of occasional mental anxiety and stress.*. What is L-lysine? L-lysine is an essential amino acid meaning the body cannot synthesize it on its own—it must be obtained through diet mainly from foods high in protein. L-lysine is important for normal growth and development and required for healthy bones skin collagen and elastin.*.  . L-lysine is converted to acetyl CoA a critical part of metabolizing carbohydrates for energy.* Lysine is also a precursor to carnitine which helps transport fatty acids into mitochondria for energy production and other functions.*.  . How does L-lysine support health? Supports immune system function.*. May support a healthy cardiovascular system.*. Supports calcium absorption making it more available for biological functions.*. Often combined with herbs or other amino acids for complementary effects such as immune or cardiovascular support or helping to reduce occasional mental stress and anxiety.*.

"As stated before when trying to get all the amounts of this you need you have to take those huge horse sized pills that are literally a pain to swallow. So this is much better; not the best taste; but it surely is better than the pain of the other alternative; plus this breaks down better in water than crushing the pills."

"This is high quality lysine for a great price. Lysine is an essential amino acid - you need it, and your body cannot manufacture it. I have read it can promote collagen formation, which can help make skin appear younger in appearance. That's always a good thing!"
