The Original Hanley Formula is a pure amino acid concentrate powder that contains all 10 Essential Amino Acids which must be supplied in the diet (arginine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine) at levels never previously available in an equine supplement.

This is the best way to top dress your existing feed ensuring all types of horses are receiving the necessary Amino Acids for their varying life stages and work loads. 

Diet Supplementation

By simply top dressing your normal feed with around 100 grams (depending on the horse) of The Hanley Formula you are increasing your horse's overall protein quality and amino acid profile.

The Hanley Formula is an easy to feed supplement which offers owners, breeders, trainers and riders from all equine fields a fully balanced protein source, rich in every essential amino acid.


Arginine - promotes growth through the release of metabolic hormones (insulin and growth hormone). An important constituent of muscle.
A precursor for creatine synthesis.
Accelerates wound and burn healing.

Histidine - necessary for growth. An important constituent of muscle.
Stimulates production of red and white blood cells.
Helps treat arthritis.
Precursor for histamine - an important neurotransmitter.

Isoleucine - One of three essential branched chain amino acids.
Used for muscular energy production.
Helps treat nervous system degeneration.

Leucine - Branched chain amino acid. Maintains muscle strength during times of physical stress and intensive exercise.
Inhibits breakdown of muscle proteins.
Stimulates insulin release.

Lysine - The most important amino acid for improving growth in young horses.
The major amino acid used as a standard for dietary content in growing horses.
Precursor for carnitine.
Aids in formation of antibodies to control viral infection.
Important in fat metabolism.

Methionine - Regulates cell metabolism and growth. Antioxidant.
Constituent of muscles.
Can assist in keratinisation of hooves - often found as an ingredient in hoof repair supplements e.g. " Farriers formula ".

Phenylalanine - Antidepressant and pain reliever.
Essential for nitrogen balance in tissues.

Threonine - Essential for optimum growth, feed conversion and nitrogen balance in tissues.
Component of digestive enzymes and immune system.

Tryptophan - Regulates growth hormone. May aid in control of nervous behaviour.
Promotes feed intake.
Precursor for production of serotonin (vasoconstrictor and stimulator of muscle construction).

Valine - Branched chain amino acid. Vital for muscle co-ordination.
Metabolised in the muscle - energy metabolism and protein synthesis

Branched Chain Amino Acids (Isoleucine, leucine and valine)
Research studies indicate these are effective in
•    Reducing lactic acid build-up
•    Improving recovery
•    Reducing muscle breakdown
