Challenges we solve

Four walls. Four ways through.

Supplement brands hit the same four walls. Here is each one, and how we take it down.

  • Amazon

    Crowded Amazon categories. Climb above the noise.

  • Ads

    Ad rejections and claim limits. Reviewed before it runs.

  • Retention

    Low repeat purchase. Turn one order into many.

  • AI search

    Invisible in AI recommendations. Get named in the answer.

Frequently asked questions

How do you market supplements online?

Through a joined-up plan across Amazon, your own store, paid media, SEO, AI search, social and retention - measured on profit.

Can supplement brands advertise on Meta and Google?

Yes, within platform policies and FDA/FTC rules. We write structure/function-safe copy and review every ad before it runs.

Why do supplement ads get rejected on Meta?

Usually for personal-attribute language or health claims. We write and review copy to Meta’s policies.

Can you help with Amazon’s supplement requirements?

Yes. We prepare compliant listings and help assemble the documentation Amazon asks for in the dietary supplement category.

Why is retention so important for supplements?

Supplements are repeat purchases, so most profit comes from customers who reorder. Retention lowers the cost of every sale.

Can you track how often AI recommends my brand?

Yes. We track brand mentions in AI answers for your priority queries over time.

Why choose a specialist agency?

Specialists already know the platform policies, claim rules and buyer behaviour in your category, so you don’t pay for them to learn. Doo Digital has worked only with nutraceutical and wellness brands since 2020.
