Stop buying thisStop Buying Mystery-Dose Multivitamins
A multivitamin's entire job is delivering specific amounts of specific nutrients. If the label won't tell you the amount, it's not doing that job, no matter how the bottle is marketed.
The practice, not a person
Vitamins and minerals with an established Daily Value have to list a percentage of that Daily Value on the label, that part is required. But herbal extracts, "energy blends," and other non-vitamin ingredients bundled into a multivitamin can still be grouped under a proprietary blend name with only a combined total weight disclosed, the same 21 CFR 101.36(c) allowance that covers pre-workout and protein blends (eCFR). A bottle can look fully dosed on the vitamin panel and still hide the actual amounts of whatever "energy complex" or "focus blend" got added on top.
If a multivitamin needs a blend name for anything beyond the vitamins and minerals with a Daily Value, ask why.
In 2025 the FTC sent notices to roughly 700 marketers warning that unsubstantiated claims can trigger civil penalties under its penalty-offense authority, specifically calling out claims that outrun the evidence behind them (FTC). That's an industry-wide compliance signal, not a finding against any single brand named here.
How to check your own bottle
- Find the Supplement Facts panel and look at every line below the core vitamins and minerals.
- Any line with a bolded name like "Blend," "Complex," or "Matrix" and one combined weight is a proprietary blend. You cannot verify individual ingredient amounts inside it.
- Compare that combined weight to the number of ingredients listed under it. Ten ingredients sharing 200mg total means most of them are present in trace amounts at best.
- A multivitamin that lists every non-core ingredient with its own milligram or microgram amount, no blend name anywhere, passes this check.
This isn't about avoiding multivitamins. It's about paying for one that tells you what's actually inside it, at a price that reflects real ingredients instead of a trademarked name for a mystery mix. Check your own bottle and tell us what you find.
