Should a supplement brand sell on marketplaces or its own DTC site?
Most US supplement brands should sell on both a marketplace and their own DTC site, but give each a different job. Marketplaces such as Amazon capture shoppers who already search for an ingredient and want fast delivery. A DTC site keeps the customer relationship, the email list and subscription revenue. The right split depends on your margin, your product's education needs and how much catalog control you can afford to give up.
- Marketplaces win existing demand: shoppers who search an ingredient by name often start there.
- DTC wins the relationship: you own the customer data, the email list and the subscription terms.
- Sequence matters: many brands launch DTC to prove the story, then add a marketplace once reviews and supply are stable.
- Claims must match everywhere: the same FTC and FDA rules apply to a listing, a product page and an ad.

“They were able to get all my ideas and work with me over a period of three to four months and create this amazing website. It's super customized, very modern, and it incorporates all the elements that I had wanted — the patient portal, nice pictures, a very interactive website, patient reviews. I would highly recommend their company to anyone who wants to make an excellent website.”
What does each channel actually give a supplement brand?
A marketplace gives you reach into shoppers who are ready to buy and already trust the checkout. A DTC site gives you margin control, first-party customer data and the freedom to explain your formula. Neither is better in general. Each answers a different commercial question, so compare them on the factors below.
| Factor | Online marketplace | Own DTC site |
|---|---|---|
| Who finds you | Shoppers searching an ingredient or category inside the marketplace | People you bring in through search, ads, email, creators and referrals |
| Customer data | Limited; the marketplace owns the buyer relationship | Full: email, purchase history, subscription status, consented SMS |
| Margin | Reduced by referral fees, fulfillment fees and in-platform ads | Higher per order, but you pay for traffic, payments and shipping |
| Pricing control | Shared with resellers and the marketplace's own pricing rules | Yours to set, bundle and discount |
| Room to educate | Fixed listing template, image slots and short copy | Long-form ingredient pages, quality documentation, FAQs, video |
| Reviews | Volume builds fast; you cannot control the format | Slower to build; you choose how they are collected and displayed |
| Subscriptions | Marketplace subscription programs on the marketplace's terms | Your own terms, cadence, offers and cancellation flow |
| Main risk | Listing suppression, unauthorized sellers, policy changes | Rising customer acquisition cost if you rely on one ad channel |
When should a supplement brand lead with a marketplace?
Lead with a marketplace when your product sits in a category shoppers already search by name, such as a single well-known ingredient. In that case demand exists and the job is to be found and chosen. A DTC-only launch would force you to pay for traffic the marketplace already has.
Signals that favor a marketplace-first launch
- Your product is a familiar ingredient or format, so little education is needed.
- You can win on price, dose, form or certification rather than on a new story.
- Your unit economics still work after marketplace fees and in-platform advertising.
- You can keep enough inventory to avoid stock-outs, which can hurt organic ranking inside a marketplace.
Expect the marketplace to review supplement listings closely. Most large marketplaces set their own requirements for supplements, which can include product testing documentation, label images and restrictions on certain ingredients and claims. Read the current policy before you list, because requirements change.
When should a supplement brand lead with its own website?
Lead with DTC when your product needs explanation before anyone buys it. Novel blends, condition-adjacent positioning, premium pricing and practitioner-backed formulas all need space to show evidence, sourcing and dosing. A listing template rarely gives you that space, and shoppers comparing on price will skip you.
A DTC-first launch also lets you test messaging before you commit inventory to a marketplace. You can see which claim, which benefit and which audience converts, then carry the winning version into listings later. Subscriptions are the other reason. When you set the terms, you can design the cadence, the offer and the cancellation flow around what customers actually need.
What a DTC-first plan needs
- Product pages that explain each ingredient, dose and the evidence behind any claim.
- An email and consented SMS program from the first order.
- A paid acquisition plan that does not depend on a single ad platform.
- Clear quality signals, such as third-party testing and manufacturing standards.
Our D2C health brand marketing guide covers the acquisition side in more depth.
How do you run a marketplace and a DTC site without them competing?
Give each channel a defined role and keep the offer structure different enough that customers are not simply comparing prices. A common pattern is single bottles on the marketplace and bundles, subscriptions and exclusive formats on the DTC site. Pricing parity on the core product avoids training buyers to hunt for discounts.
- Set a minimum advertised price policy and a short list of authorized resellers, with counsel's help.
- Keep claims identical across listing copy, product pages, packaging and ads.
- Use packaging inserts carefully, following marketplace rules on directing buyers off-platform.
- Measure blended results, because DTC ads can lift marketplace sales too.
- Review the split each quarter against margin, repeat rate and inventory risk.
Blended measurement matters most. When a creator campaign or search ad lifts branded searches, some buyers complete the purchase on the marketplace. Judging DTC ads on DTC revenue alone will undercount them. Track total branded demand and total revenue across both channels, then decide where to add budget.
What does it take to run each channel well?
A marketplace needs listing management, inventory planning and in-platform advertising. A DTC site needs a store, payments, fulfillment, customer service and a steady source of traffic. The skills differ, so a brand that runs both usually needs two operating rhythms, even with a small team.
Marketplace workload
- Listing copy, images and enhanced brand content kept consistent with your label.
- Inventory forecasting, because stock-outs cost organic placement that is slow to recover.
- In-platform search ads managed against margin, not just sales.
- Monitoring for unauthorized sellers, hijacked listings and policy notices.
DTC workload
- Site speed, checkout and subscription management.
- Paid search, paid social and creator programs that bring in new buyers.
- Email and consented SMS flows that turn first orders into repeat orders.
- Customer service that answers ingredient and dosing questions quickly and accurately.
Budget the people time, not just the fees. A marketplace account needs weekly attention to listings, stock and ads, and ranking can slip when nobody owns it. A DTC program needs a steady flow of new creative for paid social, not one launch video. Before you add a channel, name who owns it each week.
Do the same advertising rules apply on a marketplace listing?
Yes. A marketplace listing is advertising, and the FTC and FDA rules that govern your website also govern your listing copy, images and bullet points. Structure/function claims still need the FDA disclaimer. Health benefit claims still need competent and reliable scientific evidence. Reviews still cannot be faked or bought.
Under the Dietary Supplement Health and Education Act of 1994, a supplement may describe how it affects the structure or function of the body, but it may not claim to diagnose, treat, cure or prevent disease. The FTC's Health Products Compliance Guidance (December 2022) explains the evidence standard. The FTC's rule on fake reviews and testimonials took effect in October 2024 and covers reviews wherever they appear. Our supplement advertising rules guide goes deeper. Confirm specific claims with your regulatory counsel.
How should a supplement brand decide its channel split?
Decide with three numbers you already have or can estimate: contribution margin per order on each channel, expected repeat purchase rate, and how much education the product needs. A product with thin margin and low education fits a marketplace. A premium, explained product with strong repeat use fits DTC first.
Then test rather than debate. Run both channels for a set period with a fixed budget, track margin after all fees and ad spend, and compare repeat behavior. Write the test plan down first: which products, which channels, what budget, and which result would change your mind. Many brands find the answer changes by product, so one SKU may live mostly on a marketplace while another sells mostly through subscription. If you want a second view on your split, our supplement and D2C health brand marketing team can review your numbers with you. You can book a call with the US team to talk it through.

Common questions
Is it better to sell supplements on Amazon or your own website?
Neither is better in every case. Amazon and other marketplaces reach shoppers who already search an ingredient by name. Your own website keeps the customer data, the email list and subscription revenue. Most supplement brands use both, with the marketplace for existing demand and the DTC site for education, bundles and repeat orders.
Should a new supplement brand start on a marketplace?
A new brand should start on a marketplace when its product is a familiar ingredient that shoppers already search for, and when margins still work after marketplace fees and ads. If the product needs explanation, such as a novel blend or premium formula, starting with a DTC site usually tests the message more cheaply.
Do FTC and FDA rules apply to marketplace listings?
Yes. Listing titles, bullets, images and descriptions are advertising. Supplements may make structure/function claims with the required FDA disclaimer but may not claim to diagnose, treat, cure or prevent disease. Health claims need competent and reliable scientific evidence under FTC guidance. Confirm specific claims with regulatory counsel.
How do supplement brands stop marketplace and DTC prices competing?
Give each channel a role. Many brands sell single units on the marketplace and keep bundles, subscriptions and exclusive formats on their own site. A minimum advertised price policy, a short authorized reseller list and identical claims across channels reduce price conflict. Counsel should review any pricing policy before it is enforced.
How do you measure DTC ads when sales also happen on a marketplace?
Measure blended results. Ads and creator campaigns can raise branded searches, and some buyers then purchase on a marketplace instead of your site. Track total branded demand, total revenue and margin across both channels, so you do not undercount campaigns that drive marketplace sales.
A note on this guide: it explains marketing practice, not legal advice. Rules on privacy, advertising and insurance change and vary by state, so confirm anything compliance-related with your own counsel.
