How to read a supplement label (and what a proprietary blend hides)
Short answer: five things tell you most of the story — serving size, doses, forms, blends, and the "other ingredients" line. A supplement label is a disclosure document. Once you know where brands leave room for vagueness, you can judge any product in about two minutes.
1. Start with the serving size
Everything on the facts panel is per serving — and a serving might be one scoop, two capsules, or four gummies. If a product needs four units a day, the per-unit numbers are a quarter of what the panel shows, and the jar runs out four times as fast as you'd guess.
2. Read the dose, not just the name
An ingredient's presence means little without its amount. "Contains magnesium" could mean 300mg or a sprinkle. The % Daily Value column helps for vitamins and minerals, but note that plenty of ingredients — collagen, botanicals, amino acids — have no official DV at all, so for those the milligram number is the only meaningful figure.
3. Check the form
The same nutrient comes in versions your body handles differently. B12 as methylcobalamin is the active form, versus synthetic cyanocobalamin (see our B12 guide); folate as methylfolate versus folic acid (folate guide); magnesium as gentle bisglycinate versus cheap oxide (magnesium forms compared). Two labels can list identical nutrients and be very different products.
4. The proprietary-blend problem
This is the big one. A "proprietary blend" (also "complex" or "matrix") lists a group of ingredients under one total weight — say, a 2,000mg blend of six botanicals — without disclosing how much of each is inside. Legally, ingredients are listed in descending order, but the first ingredient could be 1,900mg of the cheapest one and the rest a dusting. The practical effect: you cannot tell whether any single ingredient is present at a meaningful dose. A blend isn't automatically a scam, but it removes your ability to check — and full per-ingredient disclosure removes the need to trust.
5. Don't skip "other ingredients"
Below the facts panel sits the excipient list: sweeteners, flavours, fillers, coatings, colours. This is where added sugar hides in gummies (a trade-off we cover in gummy vitamins vs powder) and where you'll spot anything you'd rather avoid.
A note on badges
Certification logos vary enormously in meaning. Product-level third-party testing certifies what's in the jar you buy; a facility registration only says the factory meets manufacturing standards. Both have value — they're just not the same claim, so read the small print under the badge.
Related questions
How many supplements is too many?
It's about total doses across everything you take — covered in can you take too many supplements.
Why do doses matter so much?
Because research is done at specific amounts — an ingredient at a token dose borrows the reputation of studies it can't match.
Are ingredients with no % Daily Value less legitimate?
No — collagen, botanicals and amino acids simply have no official DV. For those, judge by the disclosed milligram amount.
