Mineral deficiencies may well be the most common cause of disease in horses. The problem is that 1. almost all pasture is mineral deficient, 2. most feeds are formulated on the mineral levels of minerals that are necessary in the diet to prevent overt disease not to maintain top health 3. most grains contain up to 50% less important minerals than they did 50 years ago. 4. Horses like humans are individuals and all need different amounts of minerals particularly when they are stressed, diseased or exerting themselves a lot.
Subtle mineral deficiency has much to answer for. It makes immune systems weaker, it increases healing times of wounds and makes bones, cartilage and ligaments much more likely to break down and cause arthritis and perhaps most significantly makes allergies more likely. It is of course always difficult to know what your horse would have been like if mineral levels had been normal but you can certainly improve things a lot in the face of disease if you use a good supplement.
It is always difficult to know which mineral supplement to use. Most minerals like Chalk or limestone (Calcium carbonate) or Copper Sulphate are very poorly absorbed. The best-absorbed minerals are those that are found in food. This is why seaweed is particularly useful. However seaweed is not balanced for horses and can provide too much Iodine. One form of minerals that are particularly useful are those that are ’protein bound’ (chelated). Such minerals, manufactured mostly in America, are about as close to food state minerals as you can get and should be used when at all possible. GlobalVite contains high levels of chelated minerals and therefore is able to correct deficiencies very quickly.
