What Is Not In Sel-Plus
WHY IS THERE NO IRON, COPPER OR VITAMIN C IN SEL-PLUS?
Q: Since these three nutrients have important anti-oxidant roles, why not add them to Sel-Plus?
A: They are simply too reactive in both the specially fresh-sealed tin and digestive system to be mixed together.
Horses make their own vitamin C. Humans are one of the few species that, because of the lack of a crucial enzyme, do not synthesize their own vitamin C from glucose in their livers.
Signs of Deficiency: The effects of a vitamin C deficiency do not occur in horses, though it is suspected that horses over the age of twenty, or those who have been ill or stressed, might sometimes suffer low plasma concentrations of ascorbic acid that could be associated with wound infections, bleeding from the nose, and an increased susceptibility to disease. Some cases of infertility in both mares and stallions also have been reported to improve with the supplementation of vitamin C, but this has yet to be confirmed by research. In any case, oral vitamin C has been shown to be poorly absorbed by the horse. The form that is sometimes included in feeds, on the off chance it might have some beneficial effect, is ascorbyl palmitate, which horses (but few other species) can absorb fairly well. I don’t think it is a good idea to feed Vit C from the point of view of negative feedback.
I am not a fan of iron supplementation in horses. In fact, I would go out on a limb and say it is probably the most harmful supplement fed to horses everywhere. Iron deficiency anaemia is very rare. Iron is a pro-oxidant and produces cellular oxidant stress that must be counteracted by anti-oxidant supplementation. This means that excessive iron decreases performance and longevity. There is a vast amount of scientific literature which addresses this issue but it seems we all got a dose of the myth supporting iron supplementation from our Pony Club days.
The anti-oxidants – selenium, Vitamin E, beta-carotene etc are the preferred nutritional supplements for performance enhancement and to alleviate the effects of stress from increased age, pregnancy, work, stress from illness, travel, etc. The only time to supplement iron is with a veterinarian diagnosed iron-deficiency anaemia and low serum ferritin titres.
Creating an effective supplement is an art and a science. Choosing the correct ingredients is critical but choosing what not to add is a big factor in ensuring a stable shelf life. We want the horse to receive a fresh, effective and correct dose of what he needs to perform. If we add copper, it reacts with iron and selenium, if we add iron it destroys Vitamin E and reacts with the copper. We are not interested in impressing you with a long list of ingredients but we are passionate about delivering the nutrients your horse needs to perform.
Please try not to mix Sel-Plus in the same feed as supplements containing iron, copper or Vitamin C, they may decrease the effectiveness of Sel-Plus. If you wish to feed these other nutrients simply place them in a seperate feed.
