What does vitamin B1 do exactly?

Vitamin B1 contributes to ensuring that the nervous system and heart muscle function properly. Vitamin B1 also helps the conversion of carbohydrates to energy. A vitamin B1 deficiency will impact on the nervous system. For example, your cat or dog could get tired more easily, lose his appetite or exhibit signs of agitation. If you feed your pet Yarrah food, then it will be getting enough vitamin B1.
