Are there any hepatic risks administrating daily such high doses of vitamins with TWYDIL® RACING ? We recommend a daily administration of 75 g TWYDIL® RACING i.e. a supplementation of 14 vitamins in addition to the quantities available through the traditional feed. The quantitative balance between all the vitamins is essential. If even one vitamin is supplied in inadequate quantities a horse cannot achieve its maximum performance potential. The formulation is designed to obtain maximum efficiency and security. Only vitamin D may present a real risk when overdosed. But we have chosen a vitamin D content under any danger limits. There is no risk of overdose for any of the other vitamins. TWYDIL® RACING supplies all the micronutrients which support good hepatic functions such as vitamin B1, B2, B6, B12, PP, folic acid, pantothenic acid, choline and the amino acid: methionine . TWYDIL® RACING places the horse in its best physical state especially thanks to a harmonic liver function.
