Vitamin B12 is another crucial component typically absent in a vegan diet. This vitamin is vital for nerve function and the production of red blood cells. Vegan dog multivitamins often incorporate fortified B12 to help prevent deficiencies. Similarly, iron and zinc are essential minerals that may not be sufficiently available in plant-based diets, which makes their inclusion in multivitamins critical for maintaining energy levels and a robust immune system.
