Behind the Supplement Facts: How to Actually Read a Label
Every supplement has a Supplement Facts panel. Almost nobody reads it closely enough to catch the tricks. Here's what actually matters on that label — and what we do differently on ours.
Quick Answer
Four things to check before you buy: the serving size (a "3-gummy serving" can make a formula look stronger than it is), whether actives are listed individually or hidden inside a "proprietary blend" (which doesn't have to disclose amounts), the %DV so you know if a dose is meaningful or trace, and total sugar per serving, since gummies vary widely. Vita Globe lists every active ingredient's exact amount — no proprietary blends — and every batch is checked against its label before it ships.

The anatomy of a Supplement Facts panel
Every dietary supplement sold in the U.S. is required to carry a Supplement Facts panel, and the FDA's labeling guidance spells out exactly what has to be on it: serving size, the amount of each active ingredient per serving, the %DV where one has been established, and a separate "Other Ingredients" list for anything that isn't an active — fillers, binders, coatings, flavors, and colors[1]. It's a standardized format on purpose, so two products can theoretically be compared side by side. In practice, a few common formatting choices make that comparison harder than it should be.
The serving size trick
Every number on the panel is "per serving" — and the manufacturer sets what a serving is[2]. That's not inherently misleading, but it means two products can list very different headline numbers while actually delivering similar (or lesser) amounts, depending on whether a "serving" is 1 gummy or 3. Always check the serving size line first, then do the math on what you're actually taking per gummy, per day.
Why "proprietary blend" is a red flag to check
Some labels group several ingredients under a single "proprietary blend" or "complex" name with one combined weight, rather than listing each ingredient's individual amount. That's permitted under FDA labeling rules as long as the blend's total weight and every ingredient in it (in descending order of predominance) are disclosed[1] — but it means you can't tell how much of any single ingredient you're actually getting, including whether the ingredient shown first (usually the cheapest, most abundant one) makes up nearly all of the blend. If a specific active matters to you — a clinical dose of ashwagandha or biotin, for example — a proprietary blend is the one place on a label where you genuinely can't verify it from the outside.
What %DV actually tells you
The %DV shows how much a serving contributes toward a general daily reference value — it's useful for spotting whether a dose is trace (well under 100%), standard, or well above typical daily needs. Not every ingredient has an established Daily Value, in which case the label will simply state "Daily Value not established" rather than a percentage[1]. That's normal and not a red flag on its own — it just means you're relying on the raw amount (in mcg, mg, or g) instead of a percentage to judge the dose.
"Other Ingredients" — fillers, binders, and what's worth noticing
Below the Supplement Facts panel, the "Other Ingredients" list covers everything that isn't an active — gelling agents, sweeteners, colors, and flavors, in a gummy's case. This is where to check for things like gelatin versus pectin (a vegetarian/vegan distinction), artificial versus natural colors and flavors, and total sugar content, which the FDA requires to be listed but which isn't always the first thing shoppers think to compare between two "similar" gummies.
The honest summary
- Check the serving size before comparing headline numbers between two products — it changes what "per serving" actually means[2].
- A proprietary blend is legal but opaque: you get the total weight and ingredient order, not individual amounts[1].
- No %DV doesn't mean no value — some ingredients simply don't have an established Daily Value yet.
- Sugar, fillers, and gelatin vs. pectin live in "Other Ingredients," not the main panel — worth a second look.
OUR LABEL CHECK PROMISE
We don't use proprietary blends — every active ingredient on a Vita Globe label is listed individually, with its exact amount. Every batch is checked against its label for dose, sugar, and ingredient accuracy before it ships. Our gummies are made with vegan pectin rather than gelatin, and formulated with real fruit flavors rather than candy-style syrups.
Frequently Asked Questions
Is a proprietary blend automatically a bad sign?
Not automatically — it's legal and common, especially for herbal formulas. But it does mean you can't verify individual ingredient amounts, which matters more for some ingredients (where clinical research points to a specific effective dose) than others.
Why do serving sizes vary so much between similar products?
Manufacturers set their own serving size, often based on gummy size, flavor formulation, or category norms rather than a fixed standard — which is exactly why comparing "per serving" numbers without checking the serving size itself can be misleading.
What does "Daily Value not established" mean?
It means the FDA hasn't set a reference daily intake for that specific ingredient — common for many botanicals and newer ingredients. It's not an indication that the ingredient is unsafe or ineffective, just that there's no percentage benchmark to show.
Does gelatin vs. pectin actually matter?
It matters for dietary preference and restrictions — gelatin is animal-derived (usually bovine or porcine), while pectin is plant-derived and vegan/vegetarian-friendly. It's mainly a sourcing and dietary distinction rather than a nutritional one.
