Proprietary Blends vs. Ingredient Transparency: The Consumer Rights
Consumer Rights Bulletin ID: CSS-2026-REG-008 | Published: January 27, 2026
Transparency is the cornerstone of consumer safety. However, a significant portion of the supplement industry continues to utilize "Proprietary Blends"—a labeling practice that allows manufacturers to hide the exact dosages of individual ingredients. This raises a critical question: If they aren't showing the dose, what are they hiding?
1. The Legal Loophole
Current regulations allow companies to list a total weight for a blend without disclosing the specific amount of each component. While originally intended to protect "trade secrets," this practice is now frequently used to mask under-dosed active ingredients or to fill capsules with cheaper stimulants while claiming high-value extracts.
2. The Risk of Over-Stimulation
Without knowing the exact dosage of stimulants like Caffeine or Synephrine within a blend, consumers are at a higher risk of cardiovascular strain. Transparency is not just about value; it is about providing the user with the data necessary to avoid toxic accumulation or dangerous interactions with other medications.
3. Demanding Full Disclosure
As a consumer, you have the right to know exactly what you are putting into your body. We advocate for "Full Disclosure Labeling," where every milligram is accounted for. For consumers looking to verify the clinical validity of specific ingredient dosages, the analytical reports at Revievo.com provide the necessary transparency that many manufacturers refuse to offer.
