Selling health products online is a viable business, but it comes with more regulatory scrutiny than most e-commerce categories. You need to comply with federal advertising rules, meet marketplace requirements, secure payment processing that works for your product type, and handle fulfillment properly. Here’s how to set up each piece.
Know What You Can and Can’t Claim
The single biggest legal risk in selling health products online is making claims you can’t back up. The FTC requires that every objective claim in your advertising be supported by “competent and reliable scientific evidence,” which it defines as tests, research, or studies conducted by qualified experts using methods generally accepted in that field. For health benefit claims specifically, randomized, controlled human clinical trials are usually what’s expected.
Customer testimonials, animal studies, and lab (in vitro) studies are not enough on their own to substantiate a health claim. If your product page says “clinically proven to reduce joint pain,” you need actual clinical trial data behind that statement. Using softening language like “may help” or “preliminary research suggests” does not fix a deceptive claim or remove the need for substantiation.
Claims rooted in traditional use, such as “used in Ayurvedic medicine for centuries,” face the same substantiation standard as any other health claim. You especially cannot use traditional use language to suggest your product treats or cures a serious medical condition, because the FTC views this as encouraging people to skip established medical care.
On the FDA side, dietary supplements are not approved before they go to market, but their labeling is regulated. You cannot imply that your product has been reviewed or approved by the FDA. If your product is a dietary supplement, your label needs to include a standard disclaimer stating that the FDA has not evaluated the product’s claims and that it is not intended to diagnose, treat, cure, or prevent any disease. But that disclaimer on the label does not give you free rein to make bold cure claims in your ads.
Choose Where to Sell
You have three main options: your own website, a major marketplace like Amazon, or both. Each has trade-offs.
Running your own store through a platform like Shopify or WooCommerce gives you full control over branding, pricing, and customer data. You handle your own traffic through SEO, paid ads, or social media. The upside is higher margins since you’re not paying marketplace referral fees. The downside is that you’re building an audience from scratch.
Selling on Amazon puts you in front of millions of shoppers immediately, but health and beauty products come with extra requirements. Amazon requires product labels to include the product name, purpose, content amount, full ingredient list, manufacturer name and address, and any relevant warnings. Products must be new, sealed in original packaging, and carry manufacturer identifying codes like serial numbers. Amazon explicitly forbids sellers from using “FDA-approved” language on cosmetics that haven’t actually received FDA approval, using the FDA logo, or labeling products with terms like “tester” or “not for retail sale.”
If your product is classified as a dangerous good (some products containing alcohol, essential oils, or aerosols fall into this category), you’ll also need to provide a safety data sheet, test reports, and other hazardous materials documentation before Amazon will let you list and ship it.
Many sellers start with their own site to control the brand experience, then expand to marketplaces once they have inventory and fulfillment processes running smoothly.
Set Up Payment Processing
Standard payment processors like Stripe and PayPal sometimes restrict or flag health product sellers, particularly those selling dietary supplements, CBD products, or anything with recurring subscription billing. These categories are considered “high risk” because of higher-than-average chargeback rates and regulatory complexity.
If you’re selling supplements or nutraceuticals, you may need a high-risk merchant account from a processor that specializes in your category. Expect some limitations early on. Processors typically set monthly processing caps between $25,000 and $100,000 for the first three to six months while they evaluate your chargeback rate and business practices. Once you build a track record, those limits usually increase.
Fees on high-risk accounts run higher than standard e-commerce processing. You’ll generally see transaction fees in the range of 3% to 5% per sale, plus monthly account fees. Shop around and compare terms from multiple providers before committing, since rates vary significantly.
To reduce chargebacks and keep your processor happy, make your return policy clear, use recognizable billing descriptors so customers know what the charge is, and avoid aggressive auto-renewal subscription models that surprise buyers.
Follow Advertising Platform Rules
Even if your product claims are legally substantiated, advertising platforms have their own restrictions that go beyond federal law.
Meta (Facebook and Instagram) prohibits ads that generate negative self-perception to sell health, weight loss, or cosmetic products. You cannot show before-and-after comparisons for weight loss results or wrinkle treatments like Botox and fillers. Ads cannot feature close-ups of someone pinching body fat or use messaging designed to exploit insecurities about appearance. Skin whitening or bleaching products that cause permanent skin color change are banned entirely.
All ads for dietary products, weight loss products, and cosmetic procedures on Meta must be targeted to people 18 and older. Sexual wellness products face even tighter restrictions: you cannot promote sexual arousal products that focus on pleasure or enhancement.
Google Ads has a similar framework. Health supplement ads face restrictions on disease claims, and Google may require advertiser verification or certifications depending on the product category and the markets you’re targeting. Prescription weight loss products have additional geo-targeting and written permission requirements.
Many health product sellers find that content marketing, SEO, email lists, and influencer partnerships drive more consistent traffic than paid ads, partly because the ad platform restrictions make it difficult to run the kind of direct-response copy that converts well.
Source and Label Products Correctly
If you’re manufacturing or private-labeling supplements, your products need to be made in a facility that follows current Good Manufacturing Practice (cGMP) standards. This is a federal requirement, not optional. Your manufacturer should be able to provide a Certificate of Analysis for each batch, showing that the product contains what the label says it contains and is free of contaminants.
Your product label needs several elements to comply with FDA regulations for dietary supplements: the product name, a “Supplement Facts” panel listing all ingredients and amounts, the net quantity, the manufacturer or distributor’s name and address, and the required disclaimer about FDA evaluation. For cosmetics, the requirements are similar but use a standard ingredient list format instead of a Supplement Facts panel.
If you’re reselling existing branded products, make sure you’re an authorized reseller. Selling products without authorization can get your listings pulled on marketplaces and potentially expose you to trademark claims.
Handle Fulfillment and Storage
Health products, especially ingestible ones, have storage requirements that generic fulfillment warehouses may not meet. If you’re using a third-party logistics provider (3PL), confirm that they operate from an FDA-registered facility and follow GMP standards. This is the baseline for supplements.
Temperature control matters for certain products. Probiotics, liquid formulas, and some botanical extracts can degrade if stored in warm or fluctuating conditions. Check your product’s stability data and make sure your fulfillment partner can maintain appropriate temperatures if needed. Not every supplement requires refrigeration, but if yours does, a standard ambient warehouse won’t work.
Lot tracking and expiration date management are also important. A good 3PL will use first-expiry, first-out (FEFO) inventory rotation so that older stock ships before newer stock, reducing the chance of a customer receiving a product close to its expiration date.
For shipping, most health products can go via standard ground carriers. Liquids over certain volumes and aerosols may require hazmat shipping labels. If you’re selling internationally, research the import regulations of your target countries, as many nations have different rules about which ingredients are permitted in supplements and cosmetics.
Build Trust With Customers
Health products live and die on trust. Shoppers are increasingly skeptical of bold claims, and your conversion rate depends on credibility.
Third-party testing seals from organizations like NSF International or USP (United States Pharmacopeia) signal that an independent lab has verified your product’s contents. These certifications cost money and take time to obtain, but they meaningfully increase consumer confidence, especially for supplements.
Transparent ingredient sourcing helps too. If your collagen is grass-fed, your fish oil is tested for heavy metals, or your botanicals are organically grown, say so with specifics rather than vague wellness language. Customers who care about health products tend to read labels carefully.
A straightforward return policy removes purchase hesitation. Offering a 30-day money-back guarantee is standard in the category and signals that you stand behind the product. Just make sure your payment processor and fulfillment setup can handle returns smoothly, since mishandled returns are one of the fastest paths to chargebacks and bad reviews.
