Muscle Builder Supplement for Horses Product Description

Our new formulation Muscle Builder Supplement for Horses delivers the optimal amounts of the only three key ingredients proven in controlled scientific studies to promote muscle growth and aid the natural process of muscle repair.
HMB (B-hydroxy B-methylbutyrate) which is formed from the metabolism of the essential amino acid Leucine and which has been shown in studies to support the reduction of muscle protein breakdown.
Leucine is one of nine essential amino acids which must be obtained from the diet as they cannot be synthesised from other components in feeds or forage. In human sport, BCAA (leucine, isoleucine and valine) have been shown to aid in recovery processes from exercise such as supporting protein synthesis, aiding natural glycogen replacement, supporting horses natural function to reduce muscle soreness following exercise and helping maintain mental function in aerobic-based exercise. These effects are now considered to be due to Leucine.
Muscle Builder for Horses also provides the essential amino acid L-Lysine which is considered to be the first limiting amino acid when it comes to protein synthesis (i.e. muscle growth) in horses.
Muscle Builder for Horses contains the optimal amounts of human grade HMB, Leucine and Lysine to support development of muscle mass, help response to training, support recovery from muscle soreness and aid stamina.
Why doesn’t Muscle Builder use other amino acids?
All the latest research points to these three key components (Leucine, Lysine and HMB) when it comes to building, supporting and developing muscle and to aid recovery. The level at which we include these components ensures your horse gets the optimal amount required as suggested in scientific papers. When you compare many of the other brands, you will see they only supply as much amino acids as you would usually get feeding hard feed or hay.
Muscle Builder for Horses is suitable for any horse in training in any discipline and for developing muscle or helping muscle to repair and recover from hard training.
