“Is it FDA-approved?” is one of the first questions people ask before buying a fertility supplement — and the honest answer surprises many: in the US, dietary supplements are not approved by the FDA before they are sold. That doesn’t make every supplement unsafe, but it does mean the label and the company behind it matter. Here’s what the rules actually say, what to check instead, and the questions worth asking any brand — including us.
This is educational, not medical advice. Talk to your doctor before starting any supplement.
1. What “FDA-approved” does and doesn’t mean for supplements
Under the Dietary Supplement Health and Education Act (DSHEA, 1994), the FDA does not review or approve dietary supplements for safety or effectiveness before they go on the market. The manufacturer is responsible for making sure the product is safe and the label is truthful, and the FDA can act after a product is sold if it’s found unsafe or misbranded. Prescription fertility drugs such as letrozole or clomiphene are different: they go through the drug-approval process. That’s why you’ll see this on every legitimate supplement label: “These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.”
2. What the label is allowed to say
Supplements may make structure/function statements — for example, “supports reproductive wellness” — but may not claim to treat or cure a disease. So treat these as red flags on any fertility product:
- “Cures infertility,” “unblocks tubes,” “shrinks fibroids” or “guaranteed pregnancy”
- Success percentages with no source you can verify
- Before-and-after stories presented as typical results
For more on spotting those, see 7 label checks before you buy and how to read fertility supplement reviews.
3. What to check instead of an “approval”
| Check | Why it matters |
|---|---|
| Supplement Facts panel with amounts per serving | “Proprietary blends” can hide how much of each ingredient you get |
| Manufacturing standards (cGMP) | FDA rules require supplement makers to follow current Good Manufacturing Practices; a brand should be able to tell you where and how it’s made |
| Voluntary third-party testing (e.g., USP, NSF) | Optional, but independent verification of contents is a plus — ask whether a product has it rather than assuming |
| Lot number and expiry on the bottle | Needed if you ever have a question or issue |
| Allergen and “other ingredients” list | Matters for allergies and for overlap with your prenatal |
4. If you’re buying in Canada
Health Canada regulates supplements as natural health products and generally expects a product licence with an eight-digit NPN (Natural Product Number) on the label. If a product shipping to Canada has no NPN, ask the seller why. For ordering and duties, see fertility supplements in Canada: what to check before you order.
5. Questions to ask any brand before you buy
- Can I see the full Supplement Facts label before ordering?
- Where is it made, and under what manufacturing standards?
- Is there independent testing, and can I see it?
- Can I take it with my prenatal, and what overlaps?
- What should I do if I have a reaction? (Stop and call your doctor.)

FAQ
Are fertility supplements FDA-approved?
No. In the US, dietary supplements are not approved by the FDA before sale. The manufacturer is responsible for safety and truthful labeling, and the FDA can act after a product is on the market.
Does a supplement need a prescription?
No. Supplements are sold over the counter, but that doesn’t mean they’re right for everyone. Check with your doctor, especially if you take medication or are being treated for infertility.
What does ‘not evaluated by the FDA’ mean?
It’s the required disclaimer for structure/function claims. It means the FDA has not evaluated the statement and the product is not intended to diagnose, treat, cure, or prevent any disease.
How can I tell if a fertility supplement is trustworthy?
Look for a full Supplement Facts panel, no proprietary blends hiding doses, no cure or guarantee claims, clear manufacturer information, and ideally independent testing you can verify.
What should I look for on a supplement shipped to Canada?
Health Canada generally expects a product licence number (NPN) on natural health product labels. If it’s missing, ask the seller before ordering.
Can AGO send me the label before I order?
Yes. Our care team can send the product label and answer ingredient and overlap questions before you buy.
