Enhancer Release The Power 32 oz

The Enhancer's formula by Cox Vet Labs is especially effective because of its unique ability to trigger a powerful (but safe) chain reaction. Gamma Oryzanol is thought to stimulate the body to produce more of the second ingredient, Pregnenolone, which, in turn, stimulates increased bodily production of DHEA. The three of them stimulate improved production from the body's hormone and glandular systems. This sophisticated blend puts The Enhancer out in front as the most promising product for optimizing a horse's speed and strength in a safe and healthy way while increasing muscle mass.

Whether a horse is a yearling in training, in the prime of life or has moved into the teens, The Enhancer might be the best supplement for building muscle and speed, while enhancing overall health. In one and two-year-olds, The Enhancer stimulates the building of strong bones and connective tissue, as well as muscle and speed. It helps the horse in its prime to develop optimal strength and speed. As a horse ages, this unique product helps it to maintain the hormone production levels of its youth, thus helping the equine body maintain peak muscularity, speed, alertness, and overall health to a more advanced age.

  • Gamma Oryzanol...2,500mg/oz
  • DHEA...600mg/oz

Focus WT Weight  3.5 lb

With Focus WT by Source feeding a hard keeper doesn't have to be hard. Certain horses seem to need more than good feed management and parasite control to gain weight or maintain it under stress. Providing extra calories may not be enough. If your horse is already receiving adequate quantities of a balanced feeding program and an effective parasite control program, weight problems are probably the result of either the incomplete digestion of food, inefficient metabolism or problems related to temperament or stress.

Focus WT provides a unique formulation of broad spectrum support nutrients including nutritional yeast culture, enzymes, beneficial microbes, B-complex vitamins and chelated trace minerals and also the original Source micronutrients to make it all work! Source harvests and blends select varieties of cold water seaweeds for the nutrients in the Source Original formula. These nutrients include at least 60 minerals and trace elements in an organic, highly bioavailable form.

In addition, seaweeds contain other natural bio-active compounds and co-factors which may be missing from your horse's diet. These micronutrients are synergistic with all the other ingredients in Focus WT and will help to increase their effectiveness.

The 3.5 lb container will provide up to an 37 day supply for one horse.
