Because understanding what’s in your supplements shouldn’t feel like cracking a cryptic code.

Ever flipped over a supplement bottle and felt instantly overwhelmed? You’re not alone. Between serving sizes, scientific names, and fine print, labels can feel like a foreign language.

In this quick guide, we break it all down so you can shop (and supplement) with confidence!

In this guide, you’ll learn:

What qualifies as a dietary supplement
What every part of a supplement label means
Which details to double-check before you buy
Common red flags to watch for
How to tell if a brand is truly transparent

What Defines a “Dietary Supplement”?

To qualify, a product must check a few key boxes:

It’s made to supplement the diet—not to treat, cure, or prevent disease.
It contains one or more dietary ingredients such as vitamins, minerals, herbs, botanicals, amino acids, or other beneficial compounds.
It’s designed to be taken by mouth—as a pill, capsule, tablet, powder, or liquid.
It clearly says “dietary supplement” on the front label.

Once a product meets those guidelines, it falls under FDA regulation—but here’s the catch: supplements don’t need FDA approval before hitting the market. Companies can legally launch a product without prior review, as long as they claim to follow labeling rules.

That’s why you may still see products making illegal “treats” or “cures” claims on shelves—because enforcement usually happens after the fact.

How to spot trustworthy brands:

Do: Choose brands that clearly list ingredient dosages and third-party testing information.
Don’t: Trust brands that make disease or cure claims—they’re not playing by the rules.

Label Lingo: What It All Actually Means

There’s a lot of information packed onto a supplement label. Some parts, like the serving size, are pretty straightforward—while others (like the ingredient list or % Daily Value) need a little decoding.

Below, we’ll walk you through each section so you know what it all means, and how to use that info to make smarter choices.

1. The Supplement Facts Box: What’s Inside

This outlined box (similar to a Nutrition Facts panel) holds the most important details.

Serving Size & Servings Per Container

This section tells you how many servings are in the container and how much of the supplement (like one or two capsules or tablets) you’ll need per day to reach the recommended daily amount.

You can also use this info to compare value and dosage between brands.

Example: A 90-count supplement might look like a 3-month supply—but if the serving size is three tablets a day, it’ll only last one month.

Active Ingredients

This section lists the nutrients that do the work—the vitamins, minerals, or botanicals that deliver the intended benefits.

Transparency matters here. Look for ingredient forms that are clearly named and easy for your body to use—for example, ‘Magnesium Citrate’ or ‘Magnesium Glycinate’ instead of vague blends or terms like ‘Magnesium Complex.’ That way, you know exactly what form of the nutrient you’re getting and how well your body can absorb it.

Amount Per Serving & % Daily Value (%DV)

These columns show:

The amount of each nutrient (e.g., 1,000 mg of Vitamin C)
How that amount compares to your recommended daily intake (%DV)

Some nutrients won’t list a %DV because individual needs vary. When in doubt, check with your healthcare professional for guidance.

→ Seeing %DV values above 100%? That’s okay! Some nutrients are harder to absorb from supplements than from food, so the amounts are sometimes higher to make up the difference.

2. Beyond the Box: Ingredients & Add-Ons

Other Ingredients (Inactive Ingredients)

These are the non-active components—they don’t deliver nutritional benefits but play important roles in stability, texture, and consistency.

Common examples include:

Vegetable cellulose or gelatin – forms the capsule shell
Magnesium stearate or silica – keeps ingredients from clumping
Rice flour – keeps serving sizes consistent naturally
Natural flavors or sweeteners – improve taste for powders or chewables

Be cautious if you see:

Artificial dyes or colors (e.g., FD&C Red No. 40)
Artificial sweeteners (like aspartame or sucralose, if you’re avoiding them)
Hydrogenated oils or trans fats (rare but possible in softgels)
Allergens like soy, gluten, or dairy without clear labeling

Remember: Not all “other ingredients” are bad—they just shouldn’t lower the quality or effectiveness of the product.

3. The Fine Print That Matters

These smaller sections may be easy to skim past, but they tell you a lot about the brand’s integrity and how to use the supplement safely.

Suggested Use: Tells you how and when to take the supplement.

For water-soluble vitamins, excess simply passes through your system.
For fat-soluble vitamins (A, D, E, K), overdoing it can be risky.

Cautions / Warnings: Lists who should avoid the supplement (e.g., pregnant, nursing, children, certain medical conditions).
Storage: Check storage directions in order to maintain potency.
Manufacturer Name & Contact Info: Trustworthy brands make this easy to find—it’s a sign of accountability.
Lot Number & Expiration Date: Confirms freshness and quality. If missing, skip the product.
Third-Party Testing or Trust Seals

Keep an eye out for certifications that back up a brand’s promises:

GMP Certified (Good Manufacturing Practice) – ensures proper production standards
Third-Party Tested – verifies purity and potency
Vegan-Friendly / Non-GMO / Allergen-Free

Health Claims on Supplement Labels

Here’s where things can get a little confusing, and where many brands accidentally (or intentionally) cross the line.

Health claims are statements that connect a supplement to a specific effect on your body. But not all claims are created equal.

Allowed (Structure/Function Claims)

These describe how a supplement supports normal body functions. They’re educational, not medical.

Examples:

“Supports immune function.”
“Helps maintain joint health.”
“Promotes healthy digestion.”

These are compliant when backed by evidence and include the FDA disclaimer.

Not Allowed (Disease or Cure Claims)

Claims that imply a supplement can treat, prevent, or cure a medical condition are illegal.

Examples:

“Prevents colds.”
“Cures arthritis.”
“Lowers blood sugar.”
“Eliminates anxiety.”

These kinds of promises may sound convincing but they’re also a sign the brand is stretching the truth.

Pro Tip: If a label promises “miracle results,” it’s probably too good to be true. The most trustworthy brands focus on support, not cures.
