Feed companies, equine nutritionists, vets and feed testing companies generally assume that all horses have the same mineral requirements. Just observe the many mineral/vitamin mixes on the market at present. The problem with this assumption is that soil type and water source are not taken into consideration when recommending supplements. For example, many areas of Australia contain soils high in iron so iron in a supplement is rarely required and toxicities are common.
Bore, river and spring water often contain high concentrations of minerals and if you guess when adding a supplement to the feed, you are often inadvertently overdosing your horse on minerals by not taking into account the mineral levels in the water supply.
Yearlings, geldings, stallions and mares have different mineral requirements as do horses in light work compared to those in heavy work.
Once I have been advised of all the supplements and feeds your horse currently receives, taken into consideration the water and soil type then compared that to the analysed hair tissue sample, I will determine which minerals your horse actually requires. Appropriate raw minerals will be recommended that are readily available from good produce /feed stores at much cheaper prices than commercial brands or from equine nutritionists.

Individual raw minerals are far more bioavailable than branded minerals mixes which often contain minerals that your horse does not actually require or already has in excess. The minerals that your horse needs supplementing with are often in low percentages which will not address deficiencies.

Most of the commercial mineral mixes and feeds fortified with mineral/vitamins just simply do not deliver what they claim – laboratory reports of hair mineral tested horses prove this. Very few feed companies, equine nutritionists selling products or commercial mineral companies will not subject their products to clinical trials. HTMA can demonstrate the efficacy of supplementing with the appropriate raw minerals.
Take control of feeding your horse what he/she actually requires bearing in mind that most commercial mixes/feeds on the market may not be suitable for your individual horse.
