If you mention proprietary blends (aka prop blends) in the supplement industry social media groups, you tend to get a visceral reaction. In any other CPG category, a “prop blend” is considered a highly valuable trade secret. Do you know what goes into a can of Coca-Cola? How about that Oreo cookie? And the list goes on…Those formulas are a main part of what makes them $1B CPG brands. Which side is right? Is the supplement category unique? Should “prop blends” still be around today or not in the supplement industry?
