Proprietary Blends In Supplements, Explained
A proprietary or trademarked blend lists ingredients by name but discloses only the combined weight of the group, not each individual ingredient's amount.
Understanding what this means helps you evaluate any supplement label more critically, including formulas in the eye-wellness category.
Why manufacturers use blends
Companies sometimes cite protecting a unique formula ratio from competitors as the reason for blend structures. This is a legitimate business consideration, but it comes with a real tradeoff for the buyer.
The tradeoff for consumers
How to read a blend-structured label
Ingredients are typically listed in descending order by weight, so ingredients toward the end of a long blend list are likely present in smaller amounts. This isn't a substitute for exact dosing, but it offers a rough guide.
Fully-dosed formulas as a comparison point
Formulas that list each ingredient's specific milligram amount individually offer more transparency and let you directly compare the dose to published research. This is generally considered the more consumer-friendly labeling approach.
What this means for your decision
Applying this to EyeFortin
Some of EyeFortin's label uses this blend structure. We think it's more useful to flag this plainly, as we do throughout this site, than to present the label as more transparent than it actually is.
