The difference between the pump and the capsules is that we have added extra curcuminoids in the capsules. This orange powder can be seen in the transparent capsules, while the pump only provides the pure micelle nano curcumin liquid. Most people prefer capsules because of the micelle liquid taste. However, some folks like our President may use the pure liquid topically or on a toothbrush. While RevGenetics cannot provide a recommendation on how best to use it, we have heard that the liquid can be used in different ways.
