We check what is in 54 health supplements and topical products, what the published research actually shows and what the guarantees really cover — then name a top pick in each category and say plainly where the evidence is thin.
WellnessChecked is a health and wellness supplement review site that earns commissions from the brands it covers. We were founded on a single principle: that consumers deserve access to honest, research-backed information about the supplements they are considering — including where the evidence is thin.
For every review, our editorial team checks the product's label and official pages, reads the guarantee terms, and looks for published research on the product itself and on its ingredients — noting who funded it and whether the doses match.
We are transparent about how we operate: we earn affiliate commissions when readers purchase products through our links. These commissions are paid by manufacturers and fund our research. We're not aware of any price difference between using our link and going to the site directly. We earn commissions from the brands we review, and we aim to describe every product accurately. We only cover products from brands we have affiliate relationships with, so our top picks are the best of the products we cover, not of every product on the market.
We apply the same checks to every product we review, whether it is VigRX Plus (on sale since about 2007) or a newer longevity supplement like GenuinePurity NMN-H. Instead of numeric scores, we give each product a plain “best for” label and name a top pick in each category.
Important: Most products we review are dietary supplements; some are cosmetics, an OTC drug (a benzocaine spray), a fragrance or a device. None of them is a prescription medicine. Supplements are not intended to diagnose, treat, cure or prevent any disease. Always consult a qualified healthcare professional before starting any supplement program. *These statements have not been evaluated by the Food and Drug Administration.
We earn commissions from the brands we review, so we tell you exactly what we check, cite our sources and say where the evidence is thin. Every product goes through the same six checks before we write a verdict. We don't run our own lab tests or clinical trials; we read what's published and explain it plainly.
We don't give numeric scores; we give each product a “best for” label and pick a top pick per category. We only cover products from brands we have affiliate relationships with, so our top picks are the best of the products we cover, not of every product on the market. We recheck formulas, prices and guarantee terms when we update a review; the current facts were checked in October 2026.
We read the label and the official product pages to see exactly what is in each product and how much, and we flag doses that aren't disclosed.
We look for published trials of the product itself and of its main ingredients, compare the doses studied with the doses in the formula, and note who funded each study.
We read the money-back guarantee terms on the maker's site: the deadline, whether opened bottles count, who pays shipping and any subscription traps.
We note known side effects and medicine interactions for the main ingredients, and who should check with a doctor first.
We compare the price per serving with similar products, including cheaper options with comparable ingredients.
Instead of a numeric score, we give each product a short “best for” label and name a top pick for each product type, with its limits spelled out.
We review products across three health categories. Click any category to see the full list, with our top picks first, plus detailed reviews and buying guidance.
Sexual health and testosterone-support supplements, HGH-support formulas, topicals and volume products — 35 products, each checked for formula, published evidence and guarantee terms.
Libido support, skin creams, bladder support and body contouring — 10 products, each checked against the published evidence and the maker's guarantee terms.
HGH-support formulas, NMN, NMNH, trans-resveratrol, spermidine and quercetin — 9 products in an area where human evidence is still early and no supplement has been shown to slow aging.
Our top pick for each product type, chosen after checking the formula, the published research, the guarantee terms and the price. Each one has limits, which we spell out in the full reviews. We only cover products from brands we have affiliate relationships with, so these are the best of the products we cover, not of every product on the market.

Side-by-side comparisons and category guides, written with the same checks as our reviews.
Most guarantees have deadlines and conditions. Our guide explains what they really cover.
Detailed guidance on what to look for, what to avoid and how to choose the right supplement for your specific goal in each health category.
The men's health supplement market is vast, variable in quality, and often filled with exaggerated claims. Understanding what separates genuinely evidence-backed products from marketing-driven formulas is essential before purchasing.
The most important thing to verify is whether the active ingredients are present at clinically relevant doses. Many products include popular ingredients like Ashwagandha or Fenugreek but at doses far below those used in published studies. Always check that the label discloses exact ingredient amounts — products hiding behind “proprietary blends” without disclosed doses should be approached with caution.
Women's health products cover a broad range of concerns, including libido, skin, bladder support and body contouring. Few of them have been tested as finished products, and many don't disclose their doses, so it pays to check what the evidence is actually for.
For hormonal health specifically, check whether a formula contains phytoestrogens (plant compounds with weak estrogen-like effects, such as those in hops). Evidence that they ease perimenopausal symptoms is mixed, and women with hormone-sensitive conditions should consult their doctor before use.
Longevity supplements are an early-stage field. NMN has small, short human trials showing it raises blood NAD+, human trials of resveratrol show small and inconsistent effects, and spermidine research in people is limited. No human study shows that any of them slows aging.
Because the evidence is early, the practical questions are what you're actually getting and what it costs. Look for a disclosed dose per serving, the form of the compound (for example, trans-resveratrol) and, ideally, a recent certificate of analysis from an independent lab.
Everything you need to know about how we review supplements, how to use our site and what to expect from the products we cover.
Our editorial team does its own research, based on the product label, the manufacturer's pages and published studies. We earn commissions from the brands we review, and we disclose this on every page. We aim to describe every product accurately, including its limits, and we apply the same checks to every product.
No. Most products we review are dietary supplements; some are cosmetics, an OTC drug (a benzocaine spray), a fragrance or a device. None of them requires a prescription. However, we strongly recommend consulting your doctor or healthcare provider before starting any supplement program, particularly if you have an existing medical condition, are taking prescription medication, are pregnant or are breastfeeding.
We don't publish numeric scores. For each product we check the formula and doses on the label, look for published trials of the product and its ingredients, read the guarantee terms, note safety cautions and compare the price. We then give each product a short “best for” label and pick a top pick for each product type. A top pick is the best option we found for that need, not a promise that it works.
Most products we feature carry a manufacturer money-back guarantee, but the length and conditions vary by product. Terms and conditions are set by the manufacturer, not by WellnessChecked. The specific guarantee duration is shown on each individual review page. To claim a refund, you must contact the manufacturer directly — you cannot claim via WellnessChecked. Guarantees are only valid on purchases made through the official manufacturer website.
WellnessChecked earns affiliate commissions when readers purchase products via links on this site. Commissions are paid by manufacturers. We're not aware of any price difference between using our link and going to the site directly. Because we earn from the brands we review, we tell you where the evidence is weak, which guarantee conditions apply and when a cheaper option may do the same job.
We aim to recheck every review at least once a year. We also update a review when we find new published studies on the product or its key ingredients, formula or price changes, changes to guarantee terms, or changes to regulatory guidance. Each review page displays its last-updated date so you can verify currency.
Most products reviewed on WellnessChecked use botanical extracts, amino acids, vitamins and minerals, but natural ingredients can still cause side effects and interact with medicines, and few finished products have been studied for long-term use. We recommend consulting your doctor before starting any supplement, particularly for long-term use. Specific cautions are listed on each product review page.
Some men's health products — particularly HGH-releaser supplements like GenF20 Plus and GenFX — are explicitly formulated for both men and women. Others contain ingredients specifically targeting male physiology (such as testosterone support compounds) and are not appropriate for women. Where a product is suitable for women, this is noted in the review. When in doubt, consult your healthcare provider.
The supplement market is huge, and many products offer little proven benefit. This guide covers the main things to check before you buy.
The single most important differentiator between a high-quality health supplement and a substandard one is the relationship between its ingredient doses and the doses used in published clinical research. Many supplement brands include fashionable ingredients — Ashwagandha, Berberine, NMN, Resveratrol — but at doses that are a fraction of the amounts used in clinical studies. A supplement containing 50mg of Ashwagandha when the published research used 600mg is unlikely to produce the results that research suggests are possible.
At WellnessChecked, we verify not just that an ingredient is present in a formula, but that it is present at a clinically relevant dose. This is one of the most important checks in our review process — and it is why our top picks sometimes differ from popularity rankings.
cGMP (Current Good Manufacturing Practice) rules are a legal requirement for US supplement makers, covering things like identity testing, contamination controls and label accuracy. They are not a certification or an FDA approval, and the FDA doesn't approve supplements before they are sold. Many makers say they follow cGMP; we can't inspect facilities ourselves, so we report what the maker states.
A money-back guarantee lowers your financial risk, but it isn't evidence that a product works. Read the terms before you buy: most of the guarantees we checked require returned containers to arrive by a hard deadline (often 67 days from delivery), some refund only unopened bottles plus one or two opened ones, and shipping is rarely refunded. Our “Money-Back Guarantees, Explained” section below summarizes the main ones.
Men's Sexual Health Supplements: Products like VigRX Plus, Semenax and ProSolution Plus are among the most searched supplements in the men's health category. Evidence varies widely: VigRX Plus has one small published placebo-controlled trial of the product itself (its funding isn't stated), Semenax's one trial was funded and co-written by its maker, and many competitors have no product trial at all. Our men's health reviews cover 35 products.
Testosterone Support Supplements: Testosil (300 mg KSM-66 ashwagandha per serving, plus D-aspartic acid and other ingredients), TestRX (D-aspartic acid, fenugreek, zinc and magnesium) and Testodren (500 mg Furosap fenugreek extract) all disclose their doses, but none has been tested as a finished product, and some doses are below or outside what research supports. Zinc and vitamin D mainly help men who are deficient.
Anti-Aging & Longevity Supplements: NMN (nicotinamide mononucleotide), trans-resveratrol, spermidine and quercetin are now widely sold as supplements. GenuinePurity, the range we review, sells each of them, with liposomal versions of several; none of its products has been tested in a published trial. GenF20 Plus has one published trial of the product, but its main result — the change in IGF-1 versus placebo — was not statistically significant; the advertised rise comes from a later subgroup analysis.
Women's Health Products: HerSolution, Provestra and Vigorelle are the best-known women's libido products we review; none discloses ingredient amounts, and none has a published trial of the product. Kollagen Intensiv is a topical face cream (not a supplement) from the Skinception range. Confitrol24 itself hasn't been tested, but its Urox blend has one published placebo-controlled trial, funded by the company that patents Urox.
The supplements our readers search for most frequently — each with a full review covering ingredients, published evidence, guarantee terms and a clear editorial verdict.
Key ingredients that appear across our reviewed products, with plain-language notes on what the evidence does and doesn't show.
A root-only ashwagandha (Withania somnifera) extract, usually studied at 300–600 mg a day, including small trials on stress, cortisol and testosterone in men. One 8-week trial in young men found a larger testosterone rise than placebo at 600 mg a day, but end-of-study levels didn't differ significantly. Appears in: Testosil (300 mg per serving). CortiSync uses a different extract, Sensoril (300 mg).
A NAD+ precursor. Small, short human trials (roughly 10–110 people, 250–1,250 mg a day) show it raises blood NAD+; effects on health outcomes are mixed, and several trials were funded by NMN makers. No human study shows it slows aging. Appears in: GenuinePurity NMN, GenuinePurity Longevity Plus. GenuinePurity NMN-H uses a related compound, NMNH, which has no peer-reviewed human trial yet.
The form of resveratrol used in most research. It looked promising in some animal studies, but human trials show small, inconsistent effects; oral resveratrol is broken down quickly, and direct sirtuin activation in people is unproven. Appears in: GenuinePurity Trans-Resveratrol (500 mg), GenuinePurity Longevity Plus (100 mg).
A branded black pepper extract added to help absorption. Its absorption studies were funded by the supplier and tested other nutrients, not the formulas it appears in. Piperine can also affect how some prescription drugs are processed, so check with a pharmacist if you take medicines. Appears in: VigRX Plus, DIM3X, CalmLean.
Both are building blocks the body uses to make nitric oxide, which helps blood vessels relax. Many blends contain far less than the gram-level amounts used in most human studies. Appears in: VigRX Nitric Oxide (doses not disclosed), GenF20 Plus (130 mg L-arginine per serving), HyperGH 14x (520 mg L-arginine a day).
Formed when you digest cruciferous vegetables. At about 100–300 mg a day it shifts estrogen metabolism in human studies, mostly in women; we found no human trial showing it raises testosterone or improves symptoms in men. Appears in: DIM3X (200 mg).
A peptide used in skin creams, meant to prompt the skin to make more collagen. Its wrinkle data come from the ingredient supplier and the brand, not from peer-reviewed trials, and the amount in the cream isn't disclosed. Appears in: Kollagen Intensiv (a topical cream, not a supplement).
A blend of Crateva nurvala, horsetail (Equisetum arvense) and Lindera aggregata. One published placebo-controlled trial (150 adults, 8 weeks) reported fewer bathroom trips and less urgency than placebo; it was funded by the company that patents Urox and hasn't been repeated. Appears in: Confitrol24 (amount per capsule not disclosed).
Our editorial standards
Not all supplement research is equally reliable. Here is what we look for when we read the studies behind a product.
The most reliable way to test whether a supplement works: neither participants nor researchers know who got the supplement or the placebo. VigRX Plus and Semenax each have one small published trial of this kind on the product itself — uncommon in this industry — but VigRX Plus's trial doesn't state its funding, Semenax's was funded and co-written by its maker, and neither has been repeated independently.
An ingredient at a much lower dose than the one studied may do little. KSM-66 ashwagandha has been studied at 300–600 mg a day; DIM at roughly 100–300 mg a day; L-arginine usually at several grams a day. We check whether the doses on the label match the research amounts, not just whether the ingredient appears — and we flag labels that don't disclose doses at all.
A compound only helps if enough of it reaches the bloodstream. Oral resveratrol, for example, is broken down quickly by the body. Brands often add absorption aids such as BioPerine or AstraGin, or use liposomal capsules, but these are rarely tested with the specific formula, so we treat absorption claims as unproven unless a study tested the product itself.
Branded ingredients (KSM-66, Sensoril, Cognizin, Synapsa, SYN-COLL, Furosap) usually come with their own studies and a standardized specification, which makes them easier to check. But many of those studies were funded by the ingredient supplier, and a branded ingredient at a low dose is still a low dose.
Current Good Manufacturing Practice (cGMP) rules are a legal minimum for US supplement makers, not a certification or an FDA approval. They cover identity testing, contamination controls and label accuracy, but the FDA doesn't approve supplements before sale. Many makers say they follow cGMP; we can't inspect facilities ourselves, so we report what the maker states. An independent lab certificate of analysis, where available, tells you more.
We don't turn evidence into a number, but we do rank the kinds of evidence:
| Strongest | Placebo-controlled trials of the product itself, ideally independent and repeated |
| Moderate | Several human trials of the main ingredients at the doses in the formula |
| Weak | Small, uncontrolled or company-run studies, traditional use, or animal and lab data |
| None | No published human evidence at the doses used in the formula |
⚠ Important editorial note: All clinical evidence referenced in our reviews relates to the active ingredients and, where published, the specific products themselves. We do not extrapolate clinical data from one form of an ingredient to assume equivalent effects from another form. Where clinical data is limited, we say so explicitly. WellnessChecked does not make medical claims and all content is for informational purposes only. *These statements have not been evaluated by the Food and Drug Administration.
Our top picks in each category, plus the strongest alternatives where a category has fewer than five top picks. Each pick has a short label saying what it is best for. All picks are from brands that pay us commissions.

Most supplements we review come with a manufacturer money-back guarantee, but the terms vary a lot and almost all of them have conditions. Here is what the main ones actually cover, as stated on the manufacturers' own sites in October 2026 (where we could only find terms elsewhere, we say so).
Return the empty containers so they arrive within 67 days of delivery. Shipping isn't refunded and it's one refund per customer.
Advertised as lifetime, but the refund covers unopened bottles plus one opened bottle, and shipping isn't refunded. Confirm the terms with Testosil before you buy.
Semenax: return the empty containers so they arrive within 67 days of delivery; shipping isn't refunded and it's one refund per customer. HyperGH 14x's 67-day terms come from a company press release and weren't confirmed on its site.
97 days from delivery, covering up to two opened bottles plus any unopened ones. Shipping isn't refunded and it's one order per customer. GenuinePurity NMN: Heads-up: the $19 first-bottle offer auto-renews at $49 every 30 days until you cancel.
⚠ Guarantee terms: Money-back guarantees are set and honoured by the individual manufacturers — not by WellnessChecked. To claim a refund, you must contact the manufacturer directly within the stated window (most of the terms we checked count from delivery). Most terms don't say they cover purchases from other sellers, so buying from the official site is the safest option. Always retain your order confirmation email as proof of purchase. Terms and conditions are detailed on each manufacturer's website.
Common terms used in supplement science and in our reviews — explained in plain language so you can read any review with full understanding of the evidence being referenced.
Some supplements reviewed on WellnessChecked can be taken together, but combinations are rarely tested — for example, no trial has shown that NMN plus resveratrol works better than either alone. Always check for ingredient overlap (particularly with Zinc, Vitamin D and fat-soluble vitamins) to avoid exceeding safe upper limits. If you take any prescription medication, consult your doctor before adding any supplement or supplement combination.
Price variation in the supplement industry reflects several factors: ingredient form (patented vs. generic), dose levels relative to clinical research amounts, manufacturing certification standards, third-party testing investment and brand overhead. A product with a branded extract at a full research dose usually costs more than one with a generic extract at a fraction of that dose. But price is not a reliable quality indicator by itself: some premium products have no more evidence than cheaper ones, so compare the label and the research, not just the price.
Third-party marketplace reviews should be treated with caution for several reasons. First, counterfeit products are sold on Amazon for many of the supplements we review — counterfeit versions will produce different (or no) results, generating misleading negative reviews. Second, incentivised and fake reviews are widespread on Amazon. If you read user reviews anywhere, treat them as one signal among many, and give more weight to published research and clear ingredient labels.
Most oral supplement capsules and tablets should be stored in a cool, dry place away from direct sunlight and humidity. Bathrooms are not suitable storage locations due to moisture. For NMN and other longevity compounds that are sensitive to heat and moisture, some manufacturers recommend refrigeration after opening — check the specific manufacturer guidance on each product. Always follow the storage instructions on the label.
In the US, dietary supplements are regulated differently from medicines. Medicines (pharmaceuticals) must prove safety and efficacy through clinical trials before receiving marketing approval from the FDA. Dietary supplements do not require pre-market approval — they are regulated after market entry, and manufacturers cannot legally claim their products diagnose, treat, cure or prevent any disease. Most products we review are dietary supplements; some are cosmetics, an OTC drug (a benzocaine spray), a fragrance or a device. This is why our content is explicitly for informational purposes only and not a substitute for medical advice.
"Clinically studied ingredients" means the individual active compounds in a formula have been evaluated in published human clinical research. It does not necessarily mean the finished product (the specific supplement) has itself been studied in a clinical trial — a meaningfully higher bar. When we note that a product has a published clinical study, we mean a study on that specific product, not just its ingredients. This distinction is important: a few products we review, including VigRX Plus, Semenax and GenF20 Plus, have one small published study of the product itself (with limits we describe in each review); most competitors only have ingredient-level evidence.
