Metabolic Supplements for Horses

Do you have difficulty managing the health of an overweight horse? Some horses may have a metabolic condition that makes it a struggle to keep a healthy weight. While consulting your veterinarian, consider a Big Dee's supplement geared towards supporting a healthy metabolism. Serious side effects can happen when your horse is too heavy, so it's important to treat this condition quickly before it turns into founder, insulin resistance or worse. This is especially challenging with ponies and minis, but it can happen to any horse. Take a look at our Overweight Horse Guide for tips on slimming down and staying healthy.

Dmg 3000 4 lb - TB
Big Dee's Tack and Vet Supplies

DMG 3000 by Vita Flex contains 3,000 mg of DMG per ounce. It helps transport oxygen that breaks down glycogen to fuel the ATP cycle, creating energy in the body.

DMG is the popular abbreviation for the nutrient N,N-Dimethylglycine, which is found in low levels in many foods. DMG is also produced within the cells of the body and so is classified as an "intermediary metabolite."

DMG plays a crucial role in the respiratory cycle of the cells by transporting oxygen. DMG is used to help transport the oxygen that breaks down glycogen ("blood sugar") to fuel the ATP cycle. This function of DMG has led researchers to study its impact on lactic acid production in horses.

Supplementation of DMG makes additional DMG available to cells throughout the body. DMG is a water soluble nutrient and is very readily absorbed. DMG is constantly broken down as it is used in the mitochondria.

Since this metabolism occurs quickly, it is recommended that DMG be fed twice daily. 3,000 mg Per Ounce DMG 3000 is extra concentrated to deliver premium quality DMG in a smaller, easy-to-feed ¼ ounce scoop. DMG 3000’s efficient formula also makes it economical.
