Add Karma to your horse's feed for a calming effect when: Travelling. On Box Rest. Hacking. Before A Competition. Magnesium Karma contains a superior, water-soluble form of magnesium that can be quickly absorbed into the blood stream. Magnesium is known as the anti-stress mineral. This key mineral is essential to the nervous system of the horse. Magnesium is used by the horse to control blood pressure to maintain a healthy, settled nervous system. It also helps to relax muscle. Magnesium is stored in the bones and in the gut. Many sources of magnesium available to the horse are insoluble and therefore unable to easily pass into the bloodstream. When stressed, horses can quickly use up their available stores of magnesium. Vitamin C Karma is enriched with Vitamin C. This antioxidant is vital to horses under stress from exercise, training, a new environment, a change in routine, diet or other events such as foaling, weaning and competing. Vitamin C helps to mop-up free radicals and so maintains health and assists the horse to overcome stressful situations. The Vitamin C in Karma is highly soluble allowing for maximum absorption. L-tryptophan Karma is enhanced with L-tryptophan. This essential amino acid is required for the formation of proteins and some hormones, including serotonin. Serotonin is the 'feel-good', 'anti-stress' hormone. Niacin (Vitamin B3) Niacin is a B complex vitamin required for optimum energy and protein utilisation, allowing energy to be channelled into the appropriate areas. The soluble source of niacin used in Karma is readily utilised by the horse. Vanilla Vanilla makes Karma smell and taste delicious for even the fussiest feeder. Potassium Sorbate Sorbate is a natural preservative found in fruits that keeps Karma in perfect condition.
