Time and Cost Savings
Reference Standards can help manufacturers demonstrate and authenticate the quality of the dietary supplement ingredients they manufacture and use.


Increased dietary supplement ingredients safety
Reference Standards analytical results permit side-by-side comparison of this authentic material and any unknown component as a way to confirm the unknown component's identity and aid in excluding the presence of adulterating agents.
