National Animal Supplement Council (NASC), an industry group dedicated to protecting and enhancing the health of companion animals and horses throughout the United States. Founded in 2001, NASC Members are industry participants and other stakeholders of the finest animal supplements who are committed to the highest current standards of quality in the industry today.

The Council's overriding goal is to promote the health and well-being of non-human food chain animals that are given nutritional supplements by their owners, and to protect and enhance the integrity of the animal supplements industry.

The cornerstone of NASC's mission is to work cooperatively with state, federal, and international governmental officials to create a legislative and regulatory environment that provides a framework that is Fair, Reasonable, Responsible and Nationally Consistent.

Such an environment of safety, accuracy and quality serves the interests of NASC's members by ensuring that ethical manufacturing and labeling practices are complied with throughout the industry.

NASC Seal of Quality…

As part of its ongoing effort to improve and standardize the animal supplement industry, NASC initiated its Quality Seal Program. The Seal is a way for consumers to know that when they buy a product, they buy from a reputable manufacturer that has successfully completed a facility audit. Different from the NASC logo, the Seal is a privilege for members to use on their products and signifies that the company has been audited for the implementation of specific standards. Members must agree to adhere to NASC’s quality standards, part of which includes submitting to an independent audit to ensure conformance with quality system requirements.


Lysine is an amino acid and the only one for which a requirement in the horse has been established by the NRC and used for the biosynthesis of proteins. This amino acid is often the key to improving protein availability and healthy muscle function.

I only trust MVP's L-Lysine for my horse. I have used this lysine for almost Three years and what a difference it has made in his behavior. He's not as sensitive to touch and groom. I'm so thankful my Veterinarian who found his mineral deficit and to MVP.

Came packaged in an easy to store bag, instead of a bucket. I've been supplementing my TB gelding who has neurological symptoms of unknown origin, and this has worked fabulously at helping him have more good days than bad. Nothing changed but the addition of this supplement, and suddenly he also started gaining significant muscle over the butt--I can't say for SURE it was this, but like I said, nothing else changed at that time. Couple words of advice, it definitely loses potency when exposed to air, so make sure you seal it well; my guy eats it just fine with all his other stuff, but it has a strong odor and might be tough to feed to picky horses. Will definitely continue to buy and use.

Excellent product, love that it is pure and not all "fillers" so you use less and it works. L Lysine is very important!
