The Most Common Misleading Supplement Claims (and How to Spot Them)

The supplement industry is massive, but it’s also full of misleading supplement claims. Many companies rely on technical jargon, inflated numbers, and vague marketing to make products look more powerful than they really are. If you’ve ever wondered whether your capsules actually contain what the label says, this guide breaks down the most common supplement label tricks and how to avoid them.

1. Extract Ratios (25:1, 50:1, etc.)

Labels often say things like “600 mg Berberine (25:1 Extract) = 15,000 mg raw herb.” This sounds impressive, but a 25:1 ratio just means 25 parts of plant were concentrated into 1 part of extract. It doesn’t tell you how much active ingredient is inside. Without a standardisation percentage (e.g. “97% berberine”), the true dose of the compound you want is unknown.

EXTRACT RATIOS ARE MEANINGLESS ON THEIR OWN

2. Missing Standardisation Percentages

High-quality products clearly state the percentage of the active compound: e.g. Curcumin (95% curcuminoids). Low-grade supplements just list the raw herb.

• Example: 500 mg turmeric root powder gives ~15 mg curcumin, while 500 mg of a 95% extract gives ~475 mg curcumin. Unless you see a percentage, the label is probably hiding a weak raw powder.

THE WEIGHT IS MEANINGLESS - THE ACTIVE ELEMENT MATTERS

3. Proprietary Blends That Hide Dosages

Many “fat-burner” or “pre-workout” supplements use a proprietary blend. The label lists a total weight (e.g. “2000 mg blend”) with a long list of ingredients.

• The problem: it doesn’t tell you how much of each is inside. The expensive ingredient may be just a sprinkle, while most of the weight is cheap filler.

4. Elemental vs. Compound Confusion

Minerals like magnesium, zinc, and calcium are sold as compounds (oxide, citrate, glycinate). Some labels list the compound weight instead of the elemental mineral content.

• Example: “500 mg magnesium oxide” sounds strong, but it only delivers ~300 mg elemental magnesium — and oxide is poorly absorbed. By contrast, “300 mg elemental magnesium (from glycinate)” is far more effective. This is what we use at SuperDosed for this reason.

5. Spiking With Cheap Forms

Blends like “Magnesium Complex” or “Turmeric mix” often contain mostly the cheapest, least bioavailable form (or just the raw root!). Brands can legally highlight the premium form on the front of the label, even if it’s only a tiny fraction. This is why we sell Magnesium Glycinate and not cheaper mixes or forms!

6. Misleading Serving Sizes

Labels often quote dosages “per serving,” but define a serving as 3 or 4 capsules.

• Consumers assume 1 capsule = 1 serving. If you don’t check carefully, you may be taking one-third of the dose you think. 

We tell you exactly what the active dose is always. The rest is just noise.

7. NRV / %DV Tricks

Some products boast “1000% of your daily Vitamin B12!” which looks powerful, but daily values (NRVs/DVs) are based on minimums to prevent deficiency, not on optimal health. Extra percentages don’t necessarily mean extra benefits.
