The Short Answer
The FDA does not approve infant formula. Instead, they require a 90-day premarket notification before a new formula hits the shelves.
During this window, the FDA reviews the manufacturer's data to ensure the product meets strict nutritional and safety standards. If a formula fails to meet the legal requirements, the FDA can deem it "adulterated" and block it from the market.
Why This Matters
Most parents assume there is a rigorous FDA stamp of approval on every can of formula. There isn't—the system relies heavily on manufacturers self-testing and self-reporting to ensure compliance. Companies must prove their formulas support infant growth, but the FDA doesn't run the initial premarket tests themselves.
While the nutritional standards are ironclad, the system has glaring blind spots. The 2022 Abbott recall exposed major flaws in how the FDA inspects facilities for bacterial contamination like Cronobacter. This gap in oversight led to a massive nationwide shortage. Baby Formula Recalls
Furthermore, the FDA has historically dragged its feet on establishing strict limits for heavy metals in formula. A 2025 Consumer Reports investigation found concerning levels of heavy metals and chemicals in nearly half of 41 tested formulas. This finally prompted the FDA to announce new initiatives to ramp up their own testing protocols. Heavy Metals Baby Formula
What's Actually Required by the FDA
The Infant Formula Act of 1980 (and its subsequent updates) sets the rules of the road. Here is exactly what manufacturers must legally do before feeding your baby:
- 30 Essential Nutrients — The FDA mandates exact minimum (and some maximum) levels for 30 specific nutrients, ensuring the formula provides complete nutrition.
- Premarket Notification — Brands must submit their recipe, manufacturing processes, and safety assurances 90 days before selling.
- Good Manufacturing Practices (cGMPs) — Facilities must be regularly audited, and every batch must be tested for pathogens like Salmonella and Cronobacter before shipping.
- Shelf-Life Testing — Companies must conduct ongoing testing to prove the nutrients remain stable and potent throughout the product's entire expiration window.
What to Look For
Green Flags:
- Clean Label Project Purity Award — This third-party certification tests for over 400 contaminants, including heavy metals that the FDA misses. Safest Formula Brands
- Made in an FDA-registered facility — This ensures the manufacturing plant is subject to routine US health inspections.
- Meets FDA nutrient requirements — Legitimate European formulas are great, but illegally imported ones bypass FDA safety checks entirely. European Vs American Formula
Red Flags:
- Third-party online sellers — Buying imported formula from unverified websites means the product bypassed FDA supply chain oversight and might have been stored in extreme heat.
- No heavy metal transparency — Thanks to California's AB 899 law, as of 2025, formula makers must publicly post their heavy metal test results. If a brand hides this data, skip it.
The Best Options
If you want formulas that go above and beyond the baseline FDA requirements—specifically for heavy metal testing and clean ingredients—here are top picks. Safest Formula Brands

The Bottom Line
1. The FDA regulates, but doesn't "approve." They review manufacturer notifications to ensure brands meet 30 strict nutrient requirements before going to market.
2. Heavy metals are still a blind spot. While the FDA is finally ramping up testing in 2025 and 2026, you should actively look for brands that voluntarily do third-party purity testing. Arsenic In Baby Formula
3. Be careful with imports. Legally imported European formulas are perfectly safe, but buying them off gray-market websites bypasses all FDA safety nets. European Vs American Formula
FAQ
Does the FDA test baby formula for heavy metals?
Historically, the FDA's "Closer to Zero" initiative focused heavily on baby food, leaving formula with vague guidelines. However, following a 2025 Consumer Reports investigation, the FDA launched new initiatives to aggressively test infant formulas for lead, arsenic, and PFAS. Lead In Baby Formula
Can the FDA recall baby formula?
Yes. If a formula is found to be contaminated or nutritionally deficient, the FDA can mandate a recall. Manufacturers are also legally required to notify the FDA within 24 hours if they initiate a voluntary recall. Baby Formula Recalls
Are European formulas FDA approved?
No formula is technically "FDA approved," but many European brands are now FDA compliant. During the 2022 shortage, the FDA relaxed rules to allow certain European brands (like Kendamil and HiPP) to be sold legally in the US, provided they met FDA nutritional standards.
