Is the dose high enough?
A well-known ingredient at 5% of the dose used in studies is there for the label, not for your health. We show the gap for each one.

DoseAudit reviews health supplements sold online. We put every ingredient next to the amount used in published research, work out what you really pay per month, and show you how to get your money back if it doesn't work for you.

Capsule supplements, one pick from each category
The highest-scoring capsule product in each of 10 categories. The score compares the label with the research and the real price. It is not medical advice.

Nervala review
A simple two-ingredient nerve formula from a real, named company, with one ingredient dosed at the exact amount used in diabetic neuropathy trials and the other well below it, sold through a funnel whose own FAQ still calls it a heart health product.

One of the better-dosed ClickBank blood sugar formulas: its maqui berry amount matches a real trial, though the 'clogged kidney drain' framing oversells that research.

Our method
How does a DoseAudit review work?
We review the offer, not our own body. Each review reads the label, the sales page, the order form and the refund terms, then compares the ingredient amounts with published research. We don't take the product and we never make up personal results. Every review says what was checked and when.
Read the label
Every ingredient and amount per daily serving, straight from the product's Supplement Facts panel. Hidden blends are flagged.
Compare with research
Each ingredient is checked against the doses used in human trials, using the NIH Office of Dietary Supplements and PubMed.
Check the order form
We open the real checkout to see bundle prices, shipping, auto-ship and the extra offers shown after you pay.
Score and publish
Dose, price and refund terms each get a score. The verdict goes up as it is, whichever it is, with the sources listed.
What we check
What does every review look at?
Six questions decide whether a supplement offer holds up. They are the same questions a pharmacist would ask before you spend $200 on bottles.
What does a month cost?
One bottle, three or six? We divide the bundle by the days it lasts and add shipping, so you see the cost per month and per day.
Any auto-ship or add-ons?
We list the extra offers that appear after checkout and any box that signs you up for repeat deliveries.
Can you get a refund?
How many days, who handles it, whether opened bottles count and who pays for return shipping.
Are the claims backed?
"Clinically proven" and "doctor formulated" get traced to a real study and a real person, or marked as unsupported.
Who makes and sells it?
Company name, address and where it is manufactured. An offer with no one you can identify behind it loses points.
The real price
Why is the price on the sales page not what you pay?
Most supplement offers sell in bundles and show extra offers after you pay. The big headline price is usually the per-bottle price of the largest bundle, which only applies if you buy six months at once.
- Bundle pricing. A single bottle often costs 30 to 40% more per bottle than the six-pack.
- Shipping. "Free shipping" often applies only to the bigger bundles.
- Add-on offers. One or more extra products appear between payment and the thank-you page.
- Auto-ship. Some order forms include repeat deliveries. Our reviews say so at the top.
Cost per month calculator
Enter the bundle you are looking at. The result updates as you type.
Per month
Per day
Add shipping and any extra offer you accept. Based on a 30-day month. Check the serving size: 2 capsules a day from a 60-capsule bottle lasts 30 days, not 60.
Refunds
How do you get a refund on a supplement bought online?
If you paid through ClickBank or Digistore24, the refund goes through that marketplace, not only the seller. Most offers come with a 30 to 60 day refund window, some longer, and the exact terms are on your order receipt.
ClickBank refund guide Digistore24 refund guide
Every DoseAudit review has a refund box with the window, whether opened bottles are accepted and who pays for return shipping.
Find your receipt email
Look for the order email from ClickBank. It has your order number and names ClickBank as the retailer.
Open ClickBank customer support
Go to clkbank.com, ClickBank's order support site, and look up the order with your email and order number.
Ask for the refund in writing
Choose refund, not "contact vendor", and keep the ticket number. For physical products, ask whether they need the bottles back and to which address.
Cancel any repeat shipment
If you were signed up for auto-ship, cancel it in the same ticket, or the next box may be charged before the refund arrives.
Verdicts
What do the DoseAudit verdicts mean?
Each review ends in one of two verdicts, based on the average of the dose, price, refund and transparency scores. A commission never changes the verdict.
Holds up
Score 7.0 to 10
Doses match the research, the price is clear and the refund is easy to use. A reasonable buy if the goal fits you.
Worth a look
Score below 7.0
Some ingredients are dosed well and others are just for the label, hidden amounts, claims with no studies, an extra cost in the price or a refund that is hard to reach. Read the review first, because it explains why.
Warning signs
Which warning signs cost a supplement points?
These patterns show up again and again on supplement sales pages. Each one we find is named in the review, with the date we saw it, so you can check it yourself.
- Proprietary blendOne total weight for many ingredients, so you can't tell how much of each you get.
- "Clinically proven" with no studyThe claim isn't linked to any trial on the actual formula.
- A doctor you can't findA named expert with no license record, no publications and no trace outside the sales page.
- A countdown that resets"Only 3 bottles left" or a timer that starts over when you reload the page.
- A long video with no priceA 40-minute presentation that shows the price only at the end, so you can't compare.
- Promises to cure or replace medicineNo supplement can legally claim to treat or cure a disease in the US.

Doses
Vitamin K2 MK-7 doses and the blood thinner question
What MK-7 doses look like on labels versus in trials, and why people on blood thinners should ask before taking vitamin K2.
DosesHow much vitamin C is too much in a supplement?
Adults need 75 to 90 mg of vitamin C a day and the upper limit is 2,000 mg. Here is how real labels compare and how stacking adds up.
LabelsHow do I convert vitamin E IU to mg on a label?
Natural vitamin E is about 1.5 IU per mg. See the 15 mg RDA, the 1,000 mg limit and how real supplement labels print vitamin E.

Questions about DoseAudit
How the site works, how it makes money and what it is not.
Do you buy and take the supplements you review?
No. DoseAudit audits the offer: the ingredient label, the doses, the claims on the sales page, the checkout price and the refund terms. Every audit says what was read and on what date. We never describe personal results we did not have.
How does DoseAudit make money?
Some links on the site are affiliate links, through ClickBank and Digistore24. If you buy through one, we may earn a commission at no extra cost to you. Commissions never change a verdict, and products that do not hold up are published as only worth a look, with the reasons spelled out.
Are dietary supplements approved by the FDA?
No. In the United States, dietary supplements do not need FDA approval before they are sold. The maker is responsible for safety and for truthful labels, which is why checking the dose and the claims yourself matters.
What does ClickBank gravity mean?
Gravity is a ClickBank marketplace number that reflects how many different affiliates recently earned a sale from a product. It measures how well a product sells through affiliates, not whether it works. We never use it as a quality score.
Is DoseAudit medical advice?
No. DoseAudit is consumer research about products and offers. Talk to your doctor or pharmacist before starting a supplement, especially if you are pregnant, take prescription medication or have a medical condition.
Before you buy
Check the dose first, then decide.
Three questions settle most supplement offers: is there enough of what works, what does it really cost per month, and how do you get your money back. DoseAudit answers all three for every product it reviews.
