What A Proprietary Blend Actually Means
ResveraBurn's label lists two proprietary blends rather than individual ingredient amounts — a common but often misunderstood supplement-industry practice.
Understanding what this does and doesn't tell you helps you make a more informed decision.
What a proprietary blend is
A proprietary blend lists every ingredient in a formula, but combines their total combined weight into a single number instead of breaking out how much of each individual ingredient is present. It's a legal labeling practice, commonly used to protect a company's specific formula ratio from competitors.
What it means for you as a buyer
Two products with an identical list of ingredient names could contain very different actual amounts of any one ingredient. A blend could be 90% one filler ingredient and 10% split across several active ingredients, and the label alone won't tell you which is the case.
What to do about it
If exact dosing matters to your decision, contact the brand directly and ask for the specific breakdown. Some companies will share this information on request even when it isn't printed on the label.
The bottom line
ResveraBurn's use of two proprietary blends means you're trusting the brand's overall positioning rather than verifying individual ingredient strength yourself. See our full ingredients page for what is and isn't disclosed.
