Product Details

Formulated to support elevated xanthine, kynurenine, and uric acid, Ixcela’s stress marker metabolites, Ixcela Protect is a powerful antioxidant blend of NAC (N-acetyl L-cysteine), L-methionine, and selenium. Antioxidants reduce oxidative stress in the body and promote healthy growth and metabolism.

Ixcela Protect lessens inflammation, assists in detoxification, and protects the body from damage caused by free radicals. It is an important recovery tool, especially for runners, cyclists, swimmers, and rowers. Ixcela Protect is also used by mental athletes—professionals who need to optimize their energy and reduce stress markers so they can juggle numerous responsibilities.*

N-acetyl-L-cysteine (NAC), a powerful antioxidant, is used by the liver and lymphocytes to help detoxify the body. It boosts protective enzymes in the body and is thought to assist with decreasing oxidative stress.

NAC is a sulfur-containing free form of amino acid. NAC is biochemically more stable than L-cysteine, the amino acid it is derived from, and it is important for the production of the antioxidant glutathione. It has the capacity to modulate the expression of genes in the inflammatory response.

L-Methionine may promote healthy growth and metabolism. It also facilitates the creation of certain neurotransmitters (dopamine, serotonin, and melatonin). Studies indicate that L-methionine may support liver and bladder health.

L-Methionine is an essential amino acid, which means that it cannot be manufactured by the body; it must be obtained through diet or supplementation. L-Methionine supports the production of the cellular antioxidant glutathione and thereby assists in detoxification processes. In the body, L-methionine can also be converted into SAM-e (S-adenosyl methionine), a compound that may support healthy joints.

Selenium is an important free-radical scavenger. It supports the health of the thyroid gland and helps a number of antioxidant enzyme systems in the body.

Selenium is a trace mineral found in soil and water. It is also found in certain foods, such as Brazil nuts, yeast, whole grains, and seafood. Selenium has been well studied and is recognized for its importance in human growth and health. It is also needed for certain enzymes that help with normal body functions.

For adults only. Adults take two (2) capsules per day with a meal.

Warning: Keep out of reach of children.

Caution: As with any dietary supplement, consult your health care practitioner before using this product, especially if you are pregnant or nursing, anticipating surgery, taking any medications on a regular basis, or otherwise under medical supervision.
