How to Spot Fake Supplement Reviews Before You Buy
You often cannot tell a fake review just by reading it, the FTC says. Instead, check who posted it, watch for a burst of reviews in a short time, look at the reviewer's history and lean on impartial expert sources. Since 2024, an FTC rule bans fake and AI-written reviews, bought reviews and company sites posing as independent.

The problem
Why should you be careful with supplement reviews?
Reviews feel like advice from a neighbor. For supplements, they are one of the easiest things to fake and one of the weakest kinds of proof.
FDA lists personal success stories among its six tip-offs to health fraud. It says testimonials are easy to make up and are no substitute for scientific evidence (FDA, 6 Tip-offs to Rip-offs). Even an honest review tells you about one person, who may have changed their diet, their medicine or their sleep at the same time.
With nerve symptoms the stakes are higher. Tingling rises and falls on its own, so a glowing review may describe a normal good week, and trusting it may delay finding the real cause.
Warning signs
What are the signs of a fake supplement review?
No single sign proves a review is fake. Several together should make you pause.
| Warning sign | What it looks like | What to do |
|---|---|---|
| A burst of reviews | Dozens of reviews posted within a few days | Check the dates and look for a steady pattern over months |
| Thin reviewer history | A profile with one review, or only five-star reviews | Open the profile and see what else they reviewed |
| Unclear source | A "review site" run by the seller, or no link to who wrote it | Find out who owns the site and who earns from the sale |
| Hype language | Quick fixes, wonder results, "one product does it all" | Treat it as a sales pitch, not a report |
| "All natural" as proof | Safety claimed because ingredients are plants | Natural does not necessarily mean safe |
| No way to check | Star scores and order counts with no named source | Ask where the numbers come from |
Fake reviews can also be negative, the FTC notes (FTC Consumer Advice, Online Reviews). A rival may post one-star reviews, so a sudden wave of complaints deserves the same doubt as a wave of praise.
The law
What does the FTC's 2024 fake review rule ban?
On August 14, 2024, the Federal Trade Commission announced a final rule banning fake reviews and testimonials (FTC, Fake Reviews Rule, August 2024). It covers more than you might expect:
- Reviews written by AI or by people with no real experience of the product
- Buying positive or negative reviews
- Insider reviews, such as from staff, that do not disclose the connection
- Company-controlled websites that pose as independent review sites
- Suppressing honest reviews
The FTC can seek civil penalties against knowing violators (FTC, Fake Reviews Rule, August 2024). If a review looks like any item on that list, give it no weight.
Better checks
Can you tell a fake review just by reading it?
Often not. The FTC says so plainly, and suggests three checks that work better.
FTC consumer advice says you often cannot tell real reviews from fake ones just by looking (FTC Consumer Advice, Online Reviews). Look at the context instead.
Consider the source
Who runs the site, and does it earn money when you buy? A seller's own page will show its best side. That includes this site, which earns from order links.
Check the pattern
Look at dates and reviewer histories. A burst over a short period, or profiles with a single review, are classic warning signs (FTC Consumer Advice, Online Reviews).
Ask impartial experts
Government health sources, your pharmacist and your doctor have nothing to sell. Their view of the ingredients matters more than any star score.
Our reviews
Why does the Nerve Savior site show no customer reviews yet?
No review is shown until it can be matched to a real order.
Star scores, quotes and face photos from sales pages and seller briefs are not shown, because none could be matched to a real buyer. Reviews appear here only once they pass the four checks below.
- 1Order matched
A review goes live only after the order number and email match a real Nerve Savior order.
- 2Good and bad alike
Low ratings are published on the same terms as high ones, and nothing is edited except spelling.
- 3No paid or AI reviews
Federal rules ban fake reviews, reviews bought for a set opinion and AI-written testimonials.
- 4Health claims flagged
A review claiming a supplement can treat a disease gets a clear note, never a highlight.
The seller's information pack came with sample reviews, named reviewers, a star score and order totals. None of it could be traced to a real buyer, and it read like template text. Under the FTC rule, publishing it would have meant passing on reviews nobody could stand behind, so we left it out.
We also do not copy eBay buyer feedback, which rates the seller and delivery, not the capsules. How we plan to check reviews is set out on the reviews page.

Order nowWhat to trust
What should you trust instead of supplement reviews?
The label and the research. Both can be checked, and neither depends on who is telling the story.
FTC guidance says health claims need competent and reliable scientific evidence, generally randomized, controlled human trials (FTC, Health Products Compliance Guidance, 2022). Ask whether that exists for the product, not just for one ingredient.
Apply that to Nerve Savior. The label lists 11 ingredients in a 600 mg blend with no single amounts. No trial of the formula has been published. Most ingredients were studied for memory or eyes. In its favor, every ingredient is named in weight order, and the eBay listing offers 30-day returns. Read the full label and the straight answer to whether Nerve Savior is legit.
Try it yourself
How can you judge a supplement yourself without much risk?
- Delivery day
Check the seal
Look for an intact safety seal and 60 capsules. Photograph any damage before you open it.
- Days 1-30
Try it and keep notes
Take 2 capsules a day between meals. Write down symptoms once a week so you can judge honestly.
- Before day 30
Start a return on eBay
In your eBay purchases, choose the order and start a return. The listing says the seller pays return shipping.
- After it ships back
Refund through eBay
eBay shows the return and refund status in your purchase history. Keep the tracking number.
Your own notes beat a stranger's review. Buy one bottle, write down symptoms weekly, and decide before day 30. The listing offers 30-day returns, with the seller paying return shipping; see the returns page.
Before you buy
What is a quick review check before buying a supplement?
Find the owner
Is the review page run by the seller or a paid partner? Say it to yourself plainly.
Scan the dates
A cluster of reviews in a few days is a warning sign, whether they are glowing or angry.
Open three profiles
Real reviewers usually review many kinds of products over time.
Strike the hype words
Quick fixes and "works for everything" are FDA fraud tip-offs, not evidence (FDA, 6 Tip-offs to Rip-offs).
Go back to the label
Check ingredients, amounts and cautions, then talk to your doctor about your symptoms.
FAQ
Fake supplement review questions
How can you tell if supplement reviews are fake?
Often you cannot tell from the words alone, the FTC says. Check who runs the site, watch for a burst of reviews in a short period, open reviewer profiles to see their history, and compare with impartial sources such as government health pages, your pharmacist or your doctor.
Are star ratings on supplement websites reliable?
Not on their own. A star score is only as good as the reviews behind it, and many sites do not say where the numbers come from. Look for reviews tied to real orders, read the low ratings too, and weigh the label and research above any score.
What does the FTC fake review rule ban?
The rule, announced August 14, 2024, bans fake and AI-generated reviews, reviews from people with no real experience of the product, buying positive or negative reviews, undisclosed insider reviews, company-run sites posing as independent review sites, and suppressing honest reviews. The FTC can seek civil penalties.
Can negative supplement reviews be fake too?
Yes. The FTC notes that fake reviews can be negative as well as positive, and its 2024 rule bans buying either kind. A sudden wave of one-star reviews deserves the same doubt as a wave of praise. Check dates and reviewer histories before you trust either.
Why are there no Nerve Savior reviews on this website?
Because none could be verified yet. The seller's information pack included sample reviews, a star score and order totals that could not be matched to real buyers, so they were not published. No review will be shown until it can be tied to an actual order.
Are testimonials proof that a supplement works?
No. FDA lists personal testimonials among its six warning signs of health fraud and says they are easy to make up and no substitute for scientific evidence. Even honest stories describe one person, whose symptoms may have changed for other reasons. Look for controlled human trials instead.
