Every guide follows the same four steps, so you always know how a conclusion was reached.
Find the claim
We start with what labels and ads actually promise, in their own words.
Check the human evidence
We look for randomized, placebo-controlled trials in people, not only lab or animal work.
Match it to the product
We compare the studied dose and form with what is really in the bottle.
Give a plain verdict
You get a clear summary of what is supported, uncertain or exaggerated.
Four Verdicts in Every Guide
No hype and no blanket dismissals. Each claim lands in one of these buckets.
Not All Evidence Is Equal
“Studies show” can mean anything from a large placebo-controlled trial to a customer testimonial. This ladder shows how much weight each kind of evidence can carry.
Test Any Supplement Claim in Five Minutes
Before you trust a bold label, ask these five questions. If a company cannot answer them, the claim has not been shown.
- 1Is a real study named?
Look for authors, year and journal. - 2Was the actual product tested?
Same ingredients, same doses. - 3Was there a placebo group?
And were people randomly assigned? - 4What was measured?
A real symptom or only a lab marker? - 5Who ran and paid for it?
Independent, published and repeated?
Latest Supplement Guides and Evidence Reviews
New articles that put supplement claims to the test.
Common Supplement Myths, Corrected
Four ideas that cost people money and, sometimes, their health.
Plant-based ingredients can still cause side effects or interact with medicines.
Supplements are not approved before sale, and the phrase has no fixed standard.
Trials usually add the supplement to a diet plan, and the extra effect is small.
Dose, form and formula must match what was tested.
Supplement Safety and Quality Essentials
A benefit claim and a safety record are two different things.
Look for third-party testing
Seals such as USP or NSF can show a product contains what the label says. They do not prove it works.
Mind medicine interactions
Some supplements change how prescription medicines work. Tell your pharmacist or doctor what you take.
Know when to ask first
If you are pregnant, breastfeeding, have a health condition or are having surgery, check with a clinician before starting.
Supplement Questions, Answered
What is Supplement Reality?
Supplement Reality is an independent, evidence-first publication about dietary supplements. Our guides explain what human research does and does not show, so you can judge supplement claims for yourself.
Does the FDA approve supplements before they are sold?
No. In the United States, the FDA does not determine whether dietary supplements are effective before they are marketed. Supplements are regulated as a category of food rather than as drugs.
Does “clinically proven” mean a supplement works?
Not necessarily. The phrase has no fixed standard on a supplement label and may refer to a single ingredient rather than the finished product. Check for a named human study, a placebo group and a matching dose.
How do you judge supplement claims?
We look for human trials, then check whether the ingredient, dose and form match the product being sold. We also consider study size, length, funding and safety, and finish with a plain verdict.
Is this website a substitute for medical advice?
No. Our content is general information only. Talk with a doctor, pharmacist or registered dietitian before starting a supplement, especially if you take medication, are pregnant or have a health condition.
Which supplement topics do you cover?
We cover weight and fat loss, gut health, brain and cognitive support, prostate and men’s health, dental and oral health, blood sugar, skin and beauty, and sleep and recovery, plus guides on quality, safety and evidence.
