    What is it?

    Muscle Builder 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. It supports muscle development, strength, power, stamina and aids muscle recovery from exercise and is suitable for any horse in training, in any discipline.

    The formulation ingredients in muscle builder are both clinically and scientifically proven to aid muscle development and recovery and contains a staggering 5 x times more amino acids in total per feed than other brands, but importantly it contains the key amino acids that the latest scientific papers suggest are responsible for muscle development and recovery.

    What’s in it?

    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.

    L-Lysine which is considered to be the first limiting amino acid when it comes to protein synthesis (i.e. muscle growth) in horses.

    So why don't we 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 get 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.
