Monday, November 2, 2026Independent supplement reviews. No scores, no paid placements.

Read the label before you buy the bottle

Found a supplement through an ad or a video? We take it apart slowly: what the label lists, how each dose compares with human studies, who should pass on it, and what the checkout really costs. No scores, no hype.

What is in the bottle?

Each ingredient, its form and its amount per serving, plus any blend that keeps the amounts hidden.

Is there enough of it to matter?

The label dose set beside the doses tested in human trials, with NIH ODS, NCCIH and PubMed links.

Who should pass on it?

Known side effects, medicine interactions and the groups who should check with a clinician first.

What does it cost in the end?

Price per day, bundle math, shipping, upsells, subscriptions and the steps to get a refund.

Before you order a supplement you saw in an ad

Six checks that take ten minutes and can save you the price of a six-bottle bundle.

  1. Ask to see the label, not the story

    An ad can run for ten minutes without showing the Supplement Facts panel. Find it before you pay. Then check each dose against one full serving, which the FDA defines as the most the directions suggest at one time.

  2. Treat a free trial as a paid order

    The FTC says a free trial usually asks for your card number so the company can bill you if you miss the deadline. Read how long the trial lasts and how to cancel, then set a reminder.

  3. Clear the boxes you did not tick

    The FTC warns that a pre-checked box can let a company keep charging you, add more products you must pay for, or share your details. Look over the whole order form and uncheck anything you did not choose.

  4. Save the order number and the date

    ClickBank orders show as CLKBANK* on your statement. ClickBank says most products have a sixty day refund period, and the refund option disappears once it ends. Keep the confirmation email where you can find it.

  5. Check it against your medicines

    NIH asks you to tell your health care providers about every supplement you take. Some herbs interact with medicines. NCCIH says St. John’s wort can weaken birth control pills, warfarin and some heart drugs.

  6. Read reviews with one eye closed

    The FDA says success stories are easy to make up, and reviews on marketplaces and social media can be fake. The FTC adds that some reviewers are paid or get free products and never mention it.

How do you read a Supplement Facts label?

Every supplement sold in the US carries this panel. Six parts tell you most of what you need before you buy.

How to read a Supplement Facts label A sample Supplement Facts panel for a joint comfort capsule with six numbered parts: serving size, amount per serving, a proprietary blend that hides doses, other ingredients, the FDA disclaimer and a quality seal. Supplement Facts Serving Size: 2 Capsules Servings Per Container: 30 Amount Per Serving % Daily Value Vitamin D3 (as cholecalciferol) 25 mcg125% Turmeric root extract 500 mg* Joint Comfort Blend 610 mg* Boswellia resin, ginger root, black pepper, hyaluronic acid (individual amounts not listed) * Daily Value not established. Other ingredients: vegetable cellulose capsule, rice flour, silicon dioxide. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease. THIRD-PARTY TESTED 1 2 3 4 5 6
Sample label for illustration. Numbers match the notes.
  1. 1
    Serving size

    The FDA counts a serving as the largest amount the directions suggest at one time. Here that is 2 capsules, so a 30 serving bottle lasts 30 days, not 60.

  2. 2
    Amount per serving

    Each active ingredient shows its weight for one full serving. The heading may read Amount Per 2 Capsules instead. Hold this number up against the doses used in research.

  3. 3
    Proprietary blend

    FDA rules require the total weight of the blend and its ingredients listed from most to least by weight. The single amounts stay hidden, so you cannot check any one dose.

  4. 4
    Other ingredients

    This list covers what the FDA calls binders, colors, fillers, flavors and sweeteners. It is the line to read closely if you have a food allergy or avoid certain additives.

  5. 5
    The FDA disclaimer

    A label with a structure or function claim must use fixed wording: the FDA has not evaluated the statements, and the product is not meant to diagnose, treat, cure or prevent disease.

  6. 6
    Quality seals

    Seals from ConsumerLab.com, NSF International or U.S. Pharmacopeia show proper manufacture, listed ingredients and no harmful contaminant levels. NIH says they do not guarantee safety or results.

What does the research say about ingredients common in online ads?

Grades describe the human evidence for the use each ingredient is sold for, not whether a product works.

IngredientOften sold forWhat the research showsEvidence
EchinaceaColds, immune supportMay slightly lower the chance of catching a cold. Whether it shortens a cold is unclear. Some people have allergic reactions, which can be severe. Source: NCCIH: EchinaceaLimited
ElderberryColds and fluOnly early research suggests it may ease cold and flu symptoms. Raw or unripe berries contain a toxin that can cause vomiting and severe diarrhea. Source: NCCIH: European ElderWeak
ValerianSleep, stressSleep findings are inconsistent, and a 2017 sleep medicine guideline advised against it for chronic insomnia. There is too little evidence for stress or anxiety. Source: NCCIH: ValerianWeak
CranberryUrinary tract healthMay lower the risk of repeat UTIs in some women, but results vary. It is not a treatment for a current UTI. Capsules can hold less of the active compounds. Source: NCCIH: CranberryLimited

Six warning signs on a supplement sales page

We look for each of these on every product page we review, and we tell you when we find one.

One bottle for every problem

The FDA says to be suspicious of products that claim to cure a wide range of diseases. A formula pitched for weight, sleep, joints and blood sugar all at once fits that pattern. FDA: 6 Tip-offs to Rip-offs

Results on a countdown

Lines like lose 30 pounds in 30 days are a tip-off, according to the FDA. Few conditions can be treated quickly, even with legitimate products. FDA: 6 Tip-offs to Rip-offs

All natural, so it must be safe

The FDA has found products sold as all-natural cures that hid high doses of prescription drug ingredients. Natural does not mean safe, and some plants can harm or kill. FDA: 6 Tip-offs to Rip-offs

The secret they do not want you to know

Claims that the government or Big Pharma is hiding a cure are meant to distract you, the FDA says. A real cure would be widely reported and prescribed by licensed professionals. FDA: 6 Tip-offs to Rip-offs

Stories in place of studies

The FTC says an honest testimonial is not enough. The seller also needs scientific evidence that the product will work for buyers the way it worked for the person in the ad. FTC Health Products Compliance Guidance

A free trial with a short fuse

The FTC says that if you do not cancel a trial on time, you will probably be charged, and dishonest sellers make cancelling hard and keep billing you. FTC: Free Trials and Subscriptions (archived copy)

How to get your money back on an online supplement order

  1. Find the charge on your statement

    The FTC suggests watching your card statements after any trial or order. A ClickBank purchase shows up as CLKBANK*, which tells you where to go next.

  2. Look up the order at CLKBANK.COM

    Enter your order number. No number? ClickBank lets you search with your zip code or the last four digits of the card you used.

  3. Send the refund request

    Pick the order, click Request A Refund, choose Request a Refund as the ticket type, pick a reason and click Send. Most ClickBank products allow sixty days.

  4. Past the window, contact the seller

    Once the refund period ends, the button no longer shows. ClickBank says to use the email or phone number under Seller Information on your order. PayPal buyers can also ask PayPal.

  5. Dispute a billing error in writing

    For a credit card billing error, the FTC says to write to the billing inquiries address so your letter arrives within 60 days of the first bill showing it. Keep a copy, and send it certified with a return receipt.

Who should ask a clinician before taking any supplement?

People who take prescription medicines
Some herbs and medicines interact in harmful ways. NCCIH lists birth control pills, warfarin, some HIV drugs and some heart drugs among those St. John’s wort can weaken.
Anyone with surgery on the calendar
NIH asks you to tell your provider about every supplement before any procedure. NCCIH says garlic supplements may raise the risk of bleeding.
People who are pregnant or nursing
NIH says many supplements have not been well tested in this group and advises care with anything beyond a standard prenatal supplement.
Parents buying for a child
NIH advises care unless the child’s provider recommends it. In one echinacea trial, some children developed rashes that may have been allergic reactions.
People who drink alcohol or take sedatives
NCCIH says kava and valerian should not be combined with alcohol or sedatives. Kava has also been linked to rare liver injury.

Five supplement myths that sales pages rely on

MythThe FDA approved this product before it went on sale.

FactMedicines need FDA approval before they are sold. Supplements do not. The company is responsible for evidence that the product is safe and its claims are truthful.

MythA quality seal means the product works.

FactA seal shows the product was made properly, holds what the label lists and has no harmful contaminant levels. NIH says it does not guarantee safety or effectiveness.

MythNatural ingredients cannot hurt you.

FactNIH names comfrey and kava as all-natural botanicals that can harm the liver. Safety depends on the chemistry, the preparation and the amount you take.

MythHundreds of happy customers prove it works.

FactThe FDA says success stories are easy to make up and are no substitute for scientific evidence. Reviews on marketplaces and social media can be fake.

MythCranberry pills can clear up a UTI.

FactNCCIH says cranberry is not recommended as a treatment for an existing UTI. Anyone who thinks they have one should see a health care provider.

Questions about The Well Brew

Does The Well Brew test the supplements it reviews?

No. We do not personally test, take or lab-check the products we write about. We read the label, the sales page, the order terms and public research from NIH, FDA and FTC, and we link the source behind each point.

Will I find scores or star ratings here?

No, and you never will. A single number hides the parts that matter. Each review lays out the ingredients, how strong the research is for each one, the real cost per day and the refund terms, so you can weigh them yourself.

How does The Well Brew make money?

Some pages carry affiliate links. If you buy through one, we may earn a commission at no extra cost to you. Pages with these links say so near the top. A commission never changes an evidence grade or removes a red flag.

Who writes the reviews?

Maya Ellison, our Reviews Editor, writes and checks them. Maya has no medical credentials and does not give medical advice. The work is reading labels, research summaries and order terms closely, then explaining them in plain words.

Is anything on The Well Brew medical advice?

No. Our reviews explain labels, research and order terms. They cannot tell you what is right for your body. Talk with a doctor or pharmacist first, especially if you take medicines, are pregnant or nursing, or have surgery planned.

How do you decide an evidence grade?

We use four plain grades: Moderate, Limited, Weak and Avoid. Each one rests on what the NCCIH or NIH Office of Dietary Supplements page for that ingredient says, and that page is linked right beside the grade so you can check it.

Can I ask you to look at a product I saw in an ad?

Yes. Send us the product name and where you saw the ad through our contact page. We cannot cover every request. A request from a seller never buys a review, a link or a kinder write-up.

Read the label first. Then decide.

The Well Brew is general information, not medical advice. Dietary supplements are not reviewed by the FDA for safety or effectiveness before they are sold.
