Metanail Serum Pro's ingredient list has 10 headings, which name 17 individual items: witch hazel, scots pine, horsetail, gotu kola, rosemary, pelargonium graveolens, glycerin, lemon peel, aloe vera, green tea, hops, vitamin C, vitamin E, hyaluronic acid, jojoba seed oil, sage leaf and MSM. The seller calls the blend a “20-in-1” formula and points to the product label for the full list and nutritional values, so the label is where you check the count and the amounts.
No human nail study of these ingredients is cited on this page. The vitamin E, hyaluronic acid and horsetail sources below are general references, and the other ingredients need a search on PubMed, the NIH's study database.

What is in Metanail Serum Pro?
The seller describes Metanail Serum Pro as a “20-in-1 nail & feet essential formula” and says it is “Non-GMO, vegan and gluten-free.” Its main page frames it as a product for “Healthy Nails & Beautiful Feet.” The seller's FAQ refers to the product as “the supplement,” so confirm the product type with the seller before you buy. For an ingredient review of a different hair serum, see the hairovesca growth serum ingredients guide.
The seller lists these ingredients, with the benefit it gives for each:

How much of each ingredient is in a bottle?
The seller's contact page says the full list of ingredients and the nutritional values are on “the product label.” The seller's terms page (metanailcomplex.com/terms.html) does not show an amount for any ingredient. Ask the seller for a photo of the label before you order, so you can see the amounts and the total count for yourself. For how supplement labels list forms and amounts, see the magnesium supplements guide.
What does the research say about the main ingredients?
Here is what this page can point you to, ingredient by ingredient. The seller's claims are the maker's statements, not study results.
Vitamin C and vitamin E
The seller says vitamin C and vitamin E are essential for collagen production. For vitamin E, the study on hand is a March 2006 Ohio State vitamin E research release. Its researchers studied how two forms of vitamin E act once they are inside animal cells, and the release calls vitamin E “a double-edged sword.” That work was in animal cells, not on nails. For how collagen claims are weighed in general, read collagen biotin or keratin.
Hyaluronic acid
The seller says hyaluronic acid “has fantastic properties” for nail integrity. The Healthline overview of hyaluronic acid says the body makes it naturally, mostly in the skin, connective tissue and eyes, and that its main job is to retain water so tissues stay moist.
Horsetail
The seller lists horsetail in its first ingredient group. MedicineNet's horsetail article lists brittle fingernails among the uses listed for horsetail. The same article says current scientific evidence has not settled the safest dose.
The other ingredients
For glycerin, aloe vera, jojoba, MSM, hops, green tea and the rest, search each ingredient name on PubMed and read the study summaries.
Are there side effects, and who should skip it?
Its contact page says: “If you are pregnant, nursing, taking medication, or have a medical condition, consult your physician before using our products.” If you take medicine, ask a pharmacist or your clinician to check the full ingredient list against it. If a nail is thick, painful or changing shape, a clinician can look at it.
What does Metanail Serum Pro cost, and how do refunds work?
Prices as of October 31, 2026, from the seller's pack list:
| Pack | Contents as listed | Prices shown | Total shown | Savings shown |
|---|---|---|---|---|
| Basic Pack | 1 Serum Pro | $79 | $79 | $20 |
| Popular Pack | 2 Serum Pro, 1 Total Cleanse | $69 and $49 | $187 | $284 |
| Ultimate Discount Pack | 4 Serum Pro, 2 Total Cleanse, 2 free digital bonuses | $59 and $29 | $294 | $434 |
Basic has a small shipping fee, and Ultimate includes free US shipping. Metanail Total Cleanse is a second product the seller describes separately, and this article does not cover it. The larger packs show two prices without saying which is per bottle, so check the figure on the Product Page before you order.
The seller says it aims to ship within 24 hours each working day, and customers reported 5 to 10 days for domestic orders. Your charge shows on your bank statement as “CLKBANK*.”
The seller's main page offers a 60-day, 100% satisfaction guarantee and says you can “return it within 60 days of receiving it” for a full refund. Its refund page gives 60 days from receiving the order, while the FAQ on the main page words the window as “for the next 2 full months after your purchase.” Because the wording differs, confirm with the seller which one applies before you buy. The seller requires you to ship the product back at your own cost to its Aurora, CO warehouse, and the refund is a full refund minus any shipping fees. The FAQ points to a contact form for inquiries.
Is Metanail Serum Pro legitimate, and what should I check?
The seller says its ingredients are handled in a “FDA registered and inspected facility,” but facility registration with the FDA is an administrative listing and is not FDA approval, so that wording does not mean the FDA has approved the product. For more on how the FDA treats supplements, see its dietary supplements page.
The seller's contact page says its statements “have not been evaluated by the Food and Drug Administration.” Its terms page says the results testimonials are “in no way a guarantee of results.” ClickBank is the retailer, and the seller says ClickBank's role “does not constitute an endorsement, approval or review of these products.”
Could I make a version of this at home?
The seller's formula is 17 named items in one bottle. A homemade version means sourcing each item, measuring it yourself, and working out amounts without the label. The seller's terms page recommends giving the product “a fair chance,” since some people take longer to respond. That is the work the bottle does for you.
Before you order
- Ask the seller for a photo of the label with the amounts.
- Ask whether it is a serum or a supplement, and how it is meant to be used.
- Ask which refund window applies: 60 days from receiving it, or 2 full months after purchase.
- Check the per-bottle price for your pack at checkout.
