Named Ingredients vs. Proprietary Blends: Why It Matters
One of the more meaningful differences between supplement labels has nothing to do with the ingredients themselves — it's whether they're named individually at all.
What a proprietary blend is
A proprietary blend lists the ingredients in a formula without disclosing the amount of each one — only the combined weight of the whole blend is shown. This is legal and extremely common across the industry.
Why a fully named formula is meaningfully different
A formula that lists ten named ingredients — even without individual milligram amounts — is still more transparent than an unnamed blend, because at minimum you know exactly what's included, even if not how much of each. That's a real, verifiable baseline you can research independently.
What neither approach fully solves
Even a fully disclosed, named-ingredient formula still typically doesn't state per-ingredient amounts on the front-facing marketing material. For that level of detail, the actual Supplement Facts panel on the product label is the authoritative source — not any summary page describing the product.
A reasonable standard to hold products to
At minimum, look for named ingredients over an unnamed blend. Beyond that, treat amount disclosure as a bonus rather than an expectation, and check the physical label if exact quantities matter to you.
