Private label hair growth vitamins are hair, skin and nails supplements, usually biotin gummies or capsules, made by a supplement manufacturer and sold under your brand. Minimums are low: one manufacturer lists a stock hair, skin and nails gummy starting at 72 units, while others start at 500 or 2,500. The harder part is the claims. As dietary supplements, these products can make structure/function claims with the FDA disclaimer, but not claims to treat hair loss. The evidence is thinner than the marketing suggests: the NIH says there’s little scientific evidence that biotin supports hair, skin and nail health in people who aren’t deficient. And the FDA warns that high-dose biotin can distort some lab test results, which is worth stating on your label and listing.
Below I compare manufacturers, explain what you can claim, and cover the biotin warning and selling on Amazon.
Private label hair growth vitamin manufacturers
From each company’s own site, checked October 10, 2026:
| Manufacturer | Location | Product | Published minimum | Notes |
|---|---|---|---|---|
| Vitalabs | US (Atlanta-based sales team) | Hair, skin and nails gummy, 60 count, 6,000 mcg biotin per 2-gummy serving | Starting at 72 units | Shows NSF facility, FDA registration, SQF and Halal |
| Build-Your-Own-Brand | Hong Kong / Shenzhen | Hair and nail gummies | 500 units ($2.90 a unit at 500, down to $2.20 at 10,000, ex-works) | 30 to 40 day lead time; lists cGMP, ISO 22000 and ISO 9001 |
| Superior Supplement Manufacturing | Fountain Valley, California | Biotin capsules and gummies | 2,500 units of 60 count (its page also shows a larger bulk figure) | About 8 weeks for a first production run |
| SMP Nutra | Largo, Florida | Hair, skin and nails gummies | Not stated on the product page | Shows NSF, GMP and FDA-registered badges |
Some manufacturers list different numbers on different parts of the same page. Get the minimum, the biotin dose and the certifications in writing on your quote, and verify certifications with the issuing body.
My take: I’d start with a stock gummy at a low minimum, such as the 72-unit option, is the safest way to test demand. Develop a custom formula only after the first product sells through.
What the evidence says about biotin
Biotin is the headline ingredient in most hair growth vitamins. The NIH Office of Dietary Supplements gives the adequate intake for adults as 30 micrograms a day.
Most hair products contain far more. The Vitalabs gummy above lists 6,000 mcg per serving, 200 times that amount. The FDA notes that biotin is often found in supplements marketed for hair, skin and nail growth, and that intakes up to 300 mg a day have been seen.
On effectiveness, the NIH’s consumer fact sheet is cautious: it says there’s little scientific evidence for biotin’s hair, skin and nail claims, and that the small number of positive studies is too preliminary to recommend biotin for those uses.
Honestly, that should shape your marketing. Sell a routine and a supporting role, not a cure.
The biotin lab-test warning
This is the safety point every hair vitamin brand should know. The FDA says biotin intake above the recommended amount can cause falsely high or falsely low results on some lab tests. It raised the concern in safety communications in November 2017 and November 2019, and still receives reports of falsely low troponin results, a test used to help diagnose heart attacks.
What I’d do as a brand:
- Add a clear note on the label and listing: tell customers to inform their doctor they take biotin before any blood test.
- Keep the dose sensible for your positioning, and state it plainly per serving.
- Mention it in your FAQ and post-purchase email.
It’s a small step that shows customers you take their health seriously.
What you can and can’t claim
Hair growth vitamins are dietary supplements, so FDA structure/function rules apply. The FDA describes these as claims intended to affect the normal structure or function of the body. They need:
- the FDA disclaimer stating that the FDA hasn’t evaluated the claim and that the product isn’t intended to diagnose, treat, cure or prevent any disease;
- notification to the FDA no later than 30 days after you first market the product.
The line is disease. The FDA’s own example contrasts mild memory loss associated with aging (acceptable) with Alzheimer’s (a disease claim). Applying the same logic to hair:
| Wording | Where it sits |
|---|---|
| “Supports healthy hair, skin and nails” | Structure/function style claim (with the disclaimer) |
| “Supports normal hair growth” | Structure/function style claim, if your evidence supports it |
| “Treats hair loss” or “cures alopecia” | Disease claim: drug territory |
| “Regrows hair” or “reverses balding” | Drug claim |
That table is our reading of the FDA framework, not FDA wording, so have claims reviewed before launch.
The FTC adds a second test: health claims require competent and reliable scientific evidence, and that applies to supplements. Given the NIH’s view of the biotin evidence, I’d keep claims modest and tie them to the specific ingredients and studies your manufacturer provides.
Selling hair growth vitamins on Amazon
Amazon announced that, effective April 2, 2024, dietary supplement products need verification through a third-party Testing, Inspection and Certification organization, managed through the Manage Your Compliance dashboard. Budget the time and cost of testing before your launch, and check Seller Central for the current requirements in your category.
On the listing:
- Show the Supplement Facts panel clearly in the images.
- Keep claims identical to your label, with the disclaimer.
- Include the biotin lab-test note.
- State gummies per serving and servings per container, because shoppers compare cost per serving.
How I’d launch a hair vitamin brand
- Pick the format. Gummies dominate this category; capsules suit buyers avoiding sugar.
- Order samples from two manufacturers. Check taste, texture and how they hold up in heat.
- Collect documents: certifications you can verify, a Certificate of Analysis, and the full formula.
- Write claims carefully, using the table above and the FDA disclaimer.
- Add the biotin lab-test note to the label, listing and FAQ.
- Plan Amazon testing if you’ll sell there.
- Launch one product, then add a capsule or sugar-free version once reviews come in.
In my view, honesty is a competitive advantage here. A category full of “grow longer hair fast” promises leaves room for a brand that explains what its product can and can’t do.
Product ideas that pair well
Hair vitamins sit naturally next to topical hair care. Our guides to private label hair oil and private label hair conditioner cover those categories. For other supplement formats, see private label gummy vitamins and private label collagen powder.

Positioning a hair vitamin brand honestly
The category is crowded, and most listings make the same promise. That’s an opening.
I’d position the product as part of a routine. Sleep, diet, gentle styling and a daily gummy, each doing a small part. It’s believable, and it matches what the evidence supports.
Then make the details easy to trust. State the biotin dose per serving in the first image. Explain who the product is for and who should check with a doctor first, such as people with regular blood tests. Show the Supplement Facts panel without making shoppers zoom in.
Reviews follow expectations. A customer told to expect healthier-feeling hair over a few months is happier than one promised visible growth in weeks. In practice, honest positioning also means fewer refund requests and fewer angry reviews.
Mistakes new hair vitamin brands make
- Promising regrowth. It’s a drug claim and an evidence problem.
- Copying a competitor’s label. Their claims and dose may not suit your evidence or positioning.
- Skipping the biotin warning. It’s a known safety issue with a simple fix.
- Ignoring gummy logistics. Gummies can melt or clump in hot transit and storage.
- No testing budget. Amazon testing and batch Certificates of Analysis are part of the cost.
