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.

I have been using In-Sync for 60 days. I got a new horse whose body condition was less than ideal and I wanted to help her get that healthy "glow." My vet has seen her several times throughout the last 60 days and agrees her condition has improved greatly. Her coat looks healthy and she's packed on a ton of muscle in her shoulders and top line. I'm definitely sold on this product.

I have been using this product for a very short time and have already noticed a difference in my horses topline. My horse licks her bucket clean so that is a plus. So far I'm loving the results!

I started this supplement about a month ago. A friend was buying it and when her horse was put down she gave me what she had left. I put my 24 year old with cushings on it and have already noticed a huge difference in his body condition. His muscles atrophy quickly and he can't handle any type of work beyond a walk, so keeping him from "wasting away" has been a challenge. I've noticed that he has gained a bit of muscle on the top of his butt and his topline has filled in just a bit. I'll definitely be adding this to my arsenal of MVP supplements I feed all my horses.

I have seen a major change in all of my barrel horses since being on this supplement. Their topline looks so much better and their overall physique has improved! Hair coat is shiny and they feel better than ever when riding! My one mare went from middle of the 4D to top half of the 3D in the first week of feeding this supplement!

I started using this product several months ago (currently on my third round of purchasing the 4lb foil bag) and I have noticed significant results. My young gelding had problems keeping his hip from popping out during intensive exercises and this product has helped build his topline. I contribute my not needing to visit the Equine Chiropractor as much to In-Sync, which has saved me a few bills! I would certainly recommend this product if your having difficulty keeping lean muscles on your horse.
