Not sure what type of supplements you take....but I find it is easy to hide stuff in a smoothie.....I add frozen fruit, yogurt, green tea powder, protein powder, ground flax seed, and milk. It is great! If you can find your supplements in powder form I don't know why you can't add it to your smoothie. Just like they do at the smoothie bars....they have all kinds of additives ---immune booster, fat burning booster (which is what green tea does by the way), etc. Could you contact a smoothie store and ask them where they sell their additives?
