We do not use fillers in our capsuling process only the raw material. This can be done when you deal with high quality contractors willing to use alternative physical methods than your typical lubricating fillers like magnesium sterate etc.

Our capsules are +/- 2-5% so highly accurate especially given our overage which was originally 325mg per capsule but is now 350mg per capsule when the requirement is only 315mg to meet the label claim.

This is something we pride ourselves on as you know many fillers have been linked to some nasty side effects.
This is why we do not use them and we also use vegetarian capsules.
