I know vegans need to take supplements cause their diet lacks vitamins B 1&2, iron, iodine. Etc. So is their a magic supplement for vegans that provides all the essentials. After speaking to others on the web, I found the answer. I don’t need to take supplements. I get plenty of Vitamin B12 from Marmite, Vitamins B1 & B2 from spinach, soya beans, asparagus, okra and nuts. I get plenty of iron from Spinitch, kale and Kidney beans and iodine from Vecon and Seaweeds rich in iodine. You don’t even have a clue about basic nutrition do you?
