Many herbal companies use fillers in their formulas as a way to cut down on giving the customer 100% herbal content. Dherbs.com is against this custom. Fillers may help the encapsulation process by making a formula more dense for encapsulation, but fillers have no nutritional content so when you add them to herbal compounds, they take away from the compound. Fillers help the encapsulation company and herbal company, but not the customer. Fillers water down the product! Dherbs.com is against this process and custom.
