What you get here that the review sites don't do
The dose, not the ingredient list
Anyone can list ashwagandha. We check whether the bottle gives you the 240 to 600 mg the trials used, or a sprinkle for the label.
A rank that can't be bought
Merit decides the band a product sits in, and nothing we earn can move it past a better-scoring one. The full policy is published, so you can check the order against it.
One methodology, published
Every score comes from the same four weighted criteria, published in full. When we get something wrong, we publish the correction.
What's bothering you? Start there.
Most people don't need a supplement. They need an answer. Each page starts with the evidence, then ranks what's left.
Cortisol & belly fat
“Cortisol blockers” have no trial behind them. Ashwagandha at 240 to 600 mg lowered measured cortisol.
What the evidence saysJoint pain in your 40s & 50s
Glucosamine failed the GAIT trial. We say so, and show what didn't fail.
What the evidence saysHair thinning in women
Biotin only helps if you're deficient. Ferritin is the number to check first.
What the evidence saysBrain fog
Eight causes, eight fixes. Only two have a supplement with real evidence.
What the evidence saysPerimenopause
Which symptoms respond to what, and which the evidence hasn't reached.
What the evidence saysBlood sugar spikes
Berberine trials used about 1,000 mg a day. Most labels we read state a quarter to half of that.
What the evidence saysTired all the time
Three blood tests to ask for before you buy anything.
What the evidence saysConstipation & fibre
Psyllium has the strongest evidence in the gut aisle. “Detox teas” have none.
What the evidence says
Recognise yourself in one of these? The next section shows what changes when you buy on evidence instead of ratings.
Buying on ratings vs buying on evidence
Before, on star ratings
- You pick the bestseller with 40,000 five-star reviews
- The label states a dose nobody has ever tested
- Three months and 90 euros later, nothing changed
- You conclude supplements don't work
After, on trial doses
- You pick from products that reach the studied dose
- The label matches the amount the trials actually used
- You know the realistic timeline before you spend
- And when the evidence says skip it, you keep your money

Straight answers
The questions sceptical readers ask before they trust a ranking.
How does Rank of Supplements make money?
Through affiliate links. If you buy a product after clicking one of our links, the retailer pays us a commission at no extra cost to you. Commissions differ by retailer and product, which is exactly why the ranking policy is published: merit decides the band a product sits in, and nothing we earn can move it past a better-scoring one. We never accept payment for placement or reviews.
Are your rankings independent?
Yes. Rank of Supplements is independently owned and not affiliated with any supplement brand or manufacturer. Every product is scored on the same published methodology, and we publish results that cost us clicks, for example that biotin does not help hair growth in people who aren't deficient.
What does “read against the dose used in research” mean?
For each ingredient we identify the amount used in the published human trials that showed an effect, then compare it to the amount stated on the product's label. If the label states less, we say so. Nearly 1 in 5 of the 145 labels we've read falls short.
Do you test products in a lab?
We don't run our own lab. We rely on third-party certifications (NSF, USP, Informed Sport, ConsumerLab) for purity and label accuracy, and we do the label-to-trial dose comparison ourselves. Products without third-party testing score lower on that part of the methodology.
Is this medical advice?
No. Our content is educational. Supplements can interact with medications and conditions, so always speak with a qualified healthcare professional before starting anything new, especially if you are pregnant, breastfeeding or on prescription medication.
