Lysine is an essential amino acid, which means your body cannot manufacture it so it must be obtained through the diet or by supplementation. Lysine is an essential component of all proteins and works with other essential amino acids to maintain growth, lean body mass, and the body’s store of nitrogen.

Lysine acts as a precursor for several other amino acids, including L-Citrulline (needed for normal protein metabolism) and L-carnitine (needed for fat metabolism). Lysine is crucial for the formation of collagen, a major part of the body's connective tissues and appears to help the body absorb and conserve calcium and may reduce its excretion.

Lysine contributes to energy production when converted to acetyl coenzyme A, one of the principal fuels for the Krebs cycle. Lysine is needed for growth and to help maintain nitrogen balance in the body. L-lysine has many other functions in the body because it is incorporated into many proteins, which are used by the body for a variety of purposes.

Lysine supports a healthy immune system.

Benefits of Alpha-Ketoglutarate (AKG) Amino Acids:

Amino Acid Alpha-Ketoglutarates are amino acids with an alpha-ketoglutaric acid (AKG) molecule attached. This AKG transport molecule helps the amino acid bypass the gut and enter the muscle cell directly giving you superior absorption. Unlike L- form amino acids, AKGs are shuttled directly to the muscle cells rather than being absorbed and used by the small intestines for nucleotide synthesis. AKG drives the amino acid into cells creating a pro-constructive-metabolic environment.

Amino acid alpha-ketoglutarates are technically amino acids derivatives. Their ergogenic effects are similar to those of their base free form amino acids, but by molecularly bonding it to AKG, its ergogenic effects become more pronounced within the muscle cell itself. The presence of the AKG molecule not only enhances the function of amino acid and overcomes its inherent limitations, but also increases its absorption rate thereby reducing the need for large doses, which may put less stress on the body. An added benefit is that AKG is a precursor to glute., so when the AKG is finished doing its job as a shuttle molecule it gets converted into Glute.. No waste - all benefit.

We guarantee our supplements to be the freshest and purest: The majority of NutraBio products contain absolutely no fillers or excipients unless absolutely necessary for the manufacturing of the particular product. Our L-Lysine alpha-ketoglutarate is one of the few exceptions. This product is extremely hygroscopic and absorbs moisture very easily causing it to clump up and harden, so we have to add fractional amounts of silica and magnesium   stearate. We do not like to use these excipients, but in this case we must in order to run the product. We use the least amount of excipients as possible in all cases so that we can guarantee you the purest product available.

Truthful and Clear Supplement Facts Panels - No BS Proprietary Blends:

A proprietary blend is a cheap gimmick used by manufacturers to hide the real truth about what's in their product. By listing a bunch of ingredients under one blend on the label, the manufacturer only has to tell you how much of the blend is in a serving while hiding how much of each ingredient is in a serving. They do this to protect their secret formula, that’s bull, they do it so they can cheapen their product without their customers knowing. In the industry we call this “Window Dressing” the product the label looks good on the outside but there is nothing really happening on the inside. At NutraBio our Supplement Facts panels list the exact amount of each and every active ingredient in the supplement. No guessing, you know exactly what you are getting in every product we sell.
