Amino acids

The building blocks of protein. There are several amino acids and the horse uses different amino acids for different functions. Some are readily available in forage, others need to be ‘topped-up’ by the horse’s feed.


Natural chemicals such as vitamin E and vitamin C, which ‘mop-up’ and bind to ‘free radicals’. ‘ Free radicals’ are produced when cells use oxygen; excess amounts of these free radicals are associated with certain conditions, intensive exercise and ageing.
