1TDC is a proprietary blend of fatty acids that are derived from beef tallow and are then formulated into a unique fatty acid complex in a cGMP food-grade facility in the USA. These fatty acids are much different than essential fatty acids you find in products like fish oils and should not be confused with essential fatty acids.

1TDC Dual Action is a new generation of fatty acid oil technology with a different molecular structure and properties beyond fish oil and glucosamine.

This unique technology is highly and rapidly absorbed, whether applied topically on the gums or taken orally in capsule form. When it enters the body, 1TDC has a tremendous affinity for white blood cells, which allows it to get where it is needed quickly. And, when it arrives, 1TDC efficiently does the job without interfering with other elements of your pet’s health.

Your dog or cat will view 1TDC as a treat. Because of its natural beef flavor, 1TDC is palatable and easy to use.

“Finding the proper nutraceutical to incorporate into your pets’ wellness plan is so crucial and can be difficult with all the products on the market. 1TDC sets itself apart from other supplements with its key ingredient of tetradecanol, a blend of fatty acids that complements well with other supplements to serve as a comprehensive tool for your pets’ health. Originally created to help with periodontal disease, 1TDC not only improves oral health, but promotes increased performance and enhances your pets’ joint health with a focus on mobility and comfort . I strongly believe in the impact of this product and recommend it to anyone looking to incorporate an easy to use and well balanced supplement into their pets’ routine.”
