Most Helpful Review:

I have type 2 diabetes and an underactive thyroid. I'm always tired and feel exhausted. I just happen to come across an article for Lysene and decided to try it. I read all I could find and ordered it. After two weeks, I went to my primary care dr. He did some blood work and my A1C went down from 6.7 to 6.3. He also lowered my Synthroid. I have always been careful about my sugar and carb intake but still struggled. I have made some changes in my diet and evercise routine. Before I was never hungry so I only ate once a day if that. I now eat at least twice a day and sometimes three. I walk everyday on a treadmill..I have lost 20 pounds and I do not feel fatigued.I have recommended this product to a few of my diabetic friends and hoping it works as well for them. It is important to make changes in yiour diet and exercise. I will keep using this product.

Product Details

Andrew Lessman Lysine-400
Andrew Lessman's Lysine-400 is a pure, natural source of the essential amino acid L-Lysine. Lysine has become a very popular supplement because of its role in supporting the immune system, as well as its central role in fat burning and energy metabolism.

Lysine is one of nine amino acids referred to as "essential" because it cannot be produced by the body. Lysine is vital for the growth and development of body tissues and also plays a critical role in the body's production of energy, since it is a precursor to acetyl CoA, a critical component of all energy metabolism.
Additionally, Lysine is also a precursor to Carnitine, which is essential for all fat metabolism. Lysine also plays an important structural role in the formation of collagen, a vital component of healthy skin, bones, joints and connective tissue (tendons, ligaments and cartilage). Lysine also plays a role in helping the body manage Calcium. In short, Lysine plays a multitude of critical roles in our body.
