If you have bloodwork done and it shows you are lacking a vitamin or nutrient, either before or while on the diet, supplementing is probably be a good idea. Be careful of supplements that have a cellulose coating or any fillers that can cause a reaction (as they did with me), there are versions of supplements without fillers but they can be more expensive. You can try to buy the pure powders, or better yet – hit up a naturopath (or even a Botox clinic/beauty salon) and get their Meyers cocktail IV vitamin infusion. This can boost you up while your body recovers and won’t cause an autoimmune reaction like pills with fillers can.
