What Metanail Complex is
Metanail Complex is sold at metanailcomplex.com, with ClickBank processing the order, as a kit built around Metanail Serum Pro, a serum in a dropper bottle for nails and feet; the bottle is labelled “Maximum Strength”, “Smooths & Hydrates” and “Restore & Renew”. The bigger packs add Metanail Total Cleanse, capsules described as a fast detox for a complete body cleanse. The sales page calls the serum a “20-in-1 nail & feet essential formula” and promises “Incredible results in RECORD TIME!”. It avoids the word fungus, but the seller’s affiliate page pitches the product to the “anti-fungal market”, and the sales leads it gives affiliates are about toenail fungus.
The page shows no label, no amounts and no directions for the serum, and lists no ingredients for Total Cleanse.
What is in the serum
The sales page names these ingredients for Metanail Serum Pro, with no amounts:
- Plant extracts: witch hazel, Scots pine, horsetail, gotu kola, rosemary, pelargonium (geranium), lemon peel, aloe vera, organic green tea, hops and sage
- Moisturisers and oils: glycerin, hyaluronic acid and jojoba seed oil
- Vitamins and others: vitamin C, vitamin E and MSM (methylsulfonylmethane)
It also says lemon peel and aloe vera contain an active protein “known as 14 kDa” with nail-rejuvenating properties, a claim we could not match to any study. It says the ingredients are handled under the USDA National Organic Program, without saying the product itself is certified organic.
What the research says about nail fungus
- Prescription tablets: a 2017 Cochrane review of 48 studies with 10,200 people found high-quality evidence that terbinafine and azole antifungals cure toenail fungus more often than a placebo, with terbinafine probably the more effective.
- Prescription nail solutions: a 2020 Cochrane review of 56 studies with 12,501 people found high-quality evidence for efinaconazole and lower-quality evidence for tavaborole and ciclopirox, although complete cure rates were relatively low even after about a year of treatment.
- Natural remedies: a 2022 systematic review of complementary therapies for nail fungus, such as tea tree oil and propolis, found only preliminary evidence and called for proper trials. Those remedies are not in Metanail.
- Metanail’s ingredients: we found no trials of witch hazel, Scots pine, horsetail, gotu kola, hops, MSM or the other serum ingredients against nail fungus. Green tea’s main compound, EGCG, was active against nail-fungus species in a laboratory dish, which is a long way from clearing an infection under a nail. The moisturisers can make dry nails and cuticles look and feel better, which is a cosmetic benefit, not a cure.
Toenail fungus is slow to clear because a toenail takes a year or more to grow out. A product that promises results in record time, with a 60-day refund, cannot show what it does to a fungal nail before the refund window closes.
The references
The site’s references page lists about 28 links. They include studies of MSM for knee arthritis and after a half-marathon, reviews of aloe, jojoba and vitamin C, a diabetes diet review, US nutrient intake data, laboratory studies, blog posts from Healthline and a spa, and two studies of other nail products, one an uncontrolled study of a different nail oil. None tests Metanail Serum Pro or Total Cleanse.
Side effects and who should check first
- Skin: rosemary, geranium and sage extracts can irritate sensitive skin. Try the serum on a small patch first, and do not put it on broken or infected skin.
- Diabetes or poor circulation: see a doctor or podiatrist about any nail or foot problem before treating it yourself.
- Total Cleanse: with no ingredient list on the sales page, you cannot check it for allergies or interactions; ask for the label before taking it, especially if you take regular medicines.
- Is it fungus? Psoriasis, injury and other conditions can look like nail fungus. A nail clipping test confirms it.
Price and packages
One bottle of Serum Pro costs $79 plus a shipping fee, $9.95 for smaller US orders. Two Serum Pro bottles with one Total Cleanse cost $187, and four Serum Pro bottles with two Total Cleanse cost $294, both with free US shipping and two free digital bonuses. It is a one-time payment, and the charge shows as CLKBANK* on your statement. The seller’s affiliate page shows there are upsell offers after checkout. Our Metanail Complex buying guide covers shipping outside the US.
How the 60-day refund works
The sales page promises a full refund within 60 days of receiving the product, “no questions asked”, while its FAQ counts two months from your purchase. The refund policy sets the conditions: you must send back all the items you received to the warehouse in Aurora, Colorado, at your own cost, and you are refunded the purchase price minus any shipping fees. The policy also lists cases where only a partial refund is given, apparently from a template for books and software. The same Aurora warehouse handles returns for several other ClickBank sellers we review.
Realistic expectations
As a moisturising serum, Metanail Serum Pro may make dry nails and cuticles look better. It has not been shown to clear nail fungus, and nothing about it suggests it would. If you have toenail fungus, see a doctor or podiatrist: prescription tablets and nail solutions have real evidence, and a nail clipping test makes sure you are treating the right problem.
🧪 Key Ingredients
What is in the formula, with a short note on each ingredient:
🌿 Green Tea Extract
Green tea extract is a highly concentrated form of the Camellia sinensis plant, rich in bioactive polyphenols and EGCG. It is a popular supplement studied mainly for weight, cholesterol and blood sugar, with modest results so far.
🌿 Hops
Hops (Humulus lupulus) are the female seed cones of the hop plant, traditionally used in brewing but now highly valued in the supplement industry for their sedative and phytoestrogenic properties. Rich in bitter acids and flavonoids, hops are primarily utilized to improve sleep quality, reduce anxiety, and manage menopausal symptoms.
🌿 Vitamin E
Vitamin E is a group of fat-soluble compounds, mainly alpha-tocopherol, that act as antioxidants in the body. It helps protect cell membranes from oxidative damage and is involved in immune function.
🌿 Glycerin, Hyaluronic Acid and Jojoba Oil
Moisturisers that can make dry nails and cuticles look and feel better; not antifungal treatments.
🌿 Rosemary, Geranium and Sage
Aromatic extracts that can irritate sensitive skin; no nail fungus trials.
🌿 Total Cleanse (capsules)
Sold as a detox; no ingredient list on the sales page.
*Always consult with your physician before starting any new supplement.

See Why Everyone's Choosing This →How we scored Metanail Complex
Five weighted criteria — see our full methodology.
Whether the label discloses how much of each ingredient it contains, rather than hiding amounts inside a proprietary blend.
Whether the finished product has been tested in a published trial, or the claims rest on research into individual ingredients.
Monthly cost on the three-month package, the shortest course most vendors recommend (the single price for one-off digital products), compared against the rest of the category.
Length of the refund window measured against the trial period the vendor itself recommends.
How the product is sold: sales channel, checkout upsells, subscription defaults and how clearly the offer is presented.
The sales page names the serum’s ingredients but shows no label, no amounts and no directions, and gives no ingredient list at all for the Total Cleanse capsules in the bigger packs. None of the serum’s ingredients has been tested against nail fungus; its moisturisers may make dry nails look better, but the treatments with real evidence are prescription tablets and nail solutions. Buying practices score low: the page promises results in record time, the seller’s affiliate page pitches it to the anti-fungal market, its reference list is mostly about other subjects, and the refund needs every item returned at your own cost, minus shipping fees.
Final Verdict
Metanail Complex is mostly a moisturising serum. Glycerin, hyaluronic acid, jojoba oil, aloe and vitamin E may leave dry nails and cuticles looking better, but none of its ingredients has been tested against nail fungus, the page publishes no amounts, and the Total Cleanse capsules sold with the bigger packs come with no ingredient list at all. Its reference list is mostly about other subjects, such as knee arthritis and half-marathons.
If you have toenail fungus, the treatments with good evidence are prescription tablets such as terbinafine and prescription nail solutions such as efinaconazole, and even those take most of a year. Ask a doctor or podiatrist to confirm it is fungus first, and see one promptly if you have diabetes. If you try Metanail anyway, one bottle is enough to judge whether you like the serum, and the refund needs every item returned within 60 days of delivery, at your own cost.
