Do you test for potency?

Every raw material that comes into the manufacturer has to come with a certificate of assay, which is an important legal document that states what is in the product, what it is, how potent it is, and to what level of potency. Those raw materials are then quarantined and re-assayed by the manufacturer. It is assayed twice before it is put into the formula. Because of this, we don't need to do a potency test after the formula is made. Most of the ingredients that are put in were certified before they were added. It is highly regulated, and most of the reputable manufacturers have to go through several processes, such as ISO and GMP (Good Manufacturing Practices). This requires logging every raw material that comes in, testing it, making sure there is a certificate of assay for it, then quarantining it, and having double measurements when you go to manufacture it. You hold back retains, and retain samples of every batch you ever make. So there are lots of checks and balances when you are making supplements. You want to hit 100% potency, so you do a plus 10% on the ingredients in every batch so that it will also allow for any possible deviation in the blending of all these things together.
