Why are vitamins K and A missing in Alnutrin supplements ?
We decided not to include vitamin K in Alnutrin Supplements because of the controversy surrounding health effects of menadione. Vitamin K3 (also known as menadione) is a synthetic version of vitamin K. Technically menadione isn’t even a vitamin, but a precursor that is converted in the body after ingestion. Natural vitamin K is fat soluble, while menadione derivatives are water soluble and bypass the natural pathway of utilization by the body. No other forms of Vitamin K (K1 or K2) are approved as feed ingredients. According to AAFCO guidelines Vitamin K does not need to be added unless the diet contains greater than 25% fish. While most of commercial cat foods contain menadione derivatives, few companies already removed it from their formulations relying on the contribution of the dietary ingredients and intestinal synthesis of vitamin K2. All of our recipes include liver, an excellent source of vitamin A, therefore there is no need for additional Vitamin A in Alnutrin supplements. Pl
