Google Ads for Supplement & Fitness Brands: Policy, Shopping and Scaling

By Jacob Thyssen, Founder of Thyssen Ads

Short answer: Supplement and fitness brands can grow profitably on Google Ads, but only with policy-safe ads and feeds. Avoid unapproved substances and unproven health claims, keep landing pages compliant, and fix Merchant Center disapprovals fast. Then lead with Shopping, push best-sellers and high-margin products, separate brand from non-brand, use repeat purchase and bundles to justify customer acquisition, and scale budgets only where profit holds. Clean tracking is non-negotiable.

Supplements and fitness products are a great fit for Google. People search with clear intent ("creatine monohydrate 500g", "vegan protein powder", "magnesium for sleep"), they compare on price and they come back to reorder. But the category also has some of the strictest ad policies on the platform. Many brands get stuck between disapproved products and generic campaigns that only ever make money on brand.

This guide covers how we approach it.

Why supplements and fitness brands struggle on Google Ads

• Policy friction. Products or claims get disapproved, sometimes the whole Merchant Center gets suspended.
• Crowded auctions. Big marketplaces and retailers bid on the same generic terms.
• Low-price products. Average order values can be low, so CPCs need to stay efficient.
• Brand carrying everything. Returning customers search the brand name, making blended ROAS look healthy while non-brand loses money.

Part 1: Google Ads policy for supplements

Google's healthcare and medicines policies apply to supplements. Rules change and vary by country, so always check the current Google Ads and Merchant Center policy pages for each market you sell in. The principles below are what typically trips brands up.

Unapproved substances

Google maintains a list of unapproved pharmaceuticals and supplements. Products containing listed ingredients can't be advertised, regardless of local legality. Check every ingredient, including in blends and pre-workouts.

Health and performance claims

Claims that a product cures, treats or prevents disease, or promises dramatic results ("lose 10 kg in 2 weeks", "replaces medication"), get disapproved and can damage account standing. Keep claims factual and in line with what's permitted for the ingredient in the EU and each market.

Misleading content and before/after imagery

Unrealistic results, exaggerated before-and-after images and fake urgency trigger misrepresentation policies. These apply to your landing pages and site, not just the ad.

Merchant Center misrepresentation

Merchant Center reviews your entire shop. Missing contact details, unclear return policies, shipping information that doesn't match the feed or aggressive claims anywhere on the site can lead to suspension. Treat your site like it's being audited, because it is.

Practical policy checklist

1. Screen every product's ingredients against Google's unapproved list.
2. Remove disease and medical claims from titles, descriptions, ads and pages.
3. Keep contact, returns and shipping information clear and consistent.
4. Monitor disapprovals daily and fix or resubmit fast.
5. Keep policy-sensitive products in separate segments so a problem doesn't drag down your best-sellers.

Part 2: Shopping strategy for supplements and fitness

Lead with Shopping

Shoppers in this category compare product, size and price visually. Shopping (standard or Performance Max) is usually where most profitable revenue comes from.

Optimise titles for how people search

People search with format, size and benefit: "whey protein isolate chocolate 1kg", "creatine gummies", "omega-3 capsules 120". Structure titles as brand + product + key attribute + flavour + size. The same principle helped Becker.dk match real search behaviour across 800,000 products.

Push best-sellers and high-margin products

Don't fund the whole catalogue equally. Segment by margin and performance using custom labels, and put budget behind products that sell at a profit.

That's how we approached Scanfarma, a Swedish retailer of homeopathic medicine and supplements. They had tried Google Ads before with inconsistent results. We prioritised best-sellers and high-margin products, optimised continuously, and aligned email with Google Ads so growth compounded. The result: +200% revenue growth in 14 months, with stable, reliable performance. Read the Scanfarma case study.

Use bundles and subscriptions

Bundles and starter packs raise order value. Subscriptions and repeat purchase justify paying more for the first order. Make sure your bidding reflects that on purpose.

Use an efficient CSS

In Europe, Shopping ads enter the auction through a Comparison Shopping Service. With Thyssen CSS, Shopping CPCs can be up to 20% more efficient, with up to 3% additional free Shopping traffic and no changes to campaigns, feed or tracking. In a low-AOV category, that matters.

Part 3: Search strategy

• Separate brand and non-brand. Brand protects returning customers. Non-brand is where you find new ones. See our account structure guide.
• Target specific intent. "Magnesium glycinate" converts better than "supplements".
• Negative keywords. Exclude informational and irrelevant searches like "side effects", "what is", "free samples" and competitor-unrelated terms that spend without selling.
• Compliant ad copy. Focus on quality, ingredients, testing, flavour, delivery and price, not medical outcomes.

Part 4: Tracking and profit

Supplement margins vary a lot between own-brand products and resold brands. That makes profit-based bidding especially valuable.

• Set up server-side tracking so conversions aren't lost to browsers and consent.
• Send profit, not just revenue, as conversion value where possible.
• Account for returning customer value when setting targets.

Part 5: Scaling supplements and fitness on Google Ads

Scale what works, step by step

Raise budgets while results beat your target and pull back the moment they don't. Steady weekly improvements beat big bets. That discipline is how Scanfarma kept growth stable month after month.

Expand into new markets

Supplement and fitness brands in Scandinavia often expand across the Nordics, then into Germany, the Netherlands or the UK. Check policy and ingredient rules per market, localise feeds and claims, and roll out one proven structure country by country. For Unsolved, that approach turned six European markets profitable in six months. Read the Unsolved case study.

Plan for seasonality

January resolutions, summer and Black November drive demand spikes in fitness. Prepare budgets and stock before the peak, not during it.

The bottom line

Supplements and fitness can be one of the most profitable categories on Google, if you stay compliant, lead with a well-structured Shopping setup, push products that actually make money, and scale with discipline.

FAQ

Can you advertise supplements on Google Ads?

Yes, most supplements can be advertised. Products with ingredients on Google's unapproved substances list can't, and ads, feeds and landing pages must avoid unproven health and medical claims. Rules vary by country, so check current policy for each market.

Why are my supplement products disapproved in Merchant Center?

Common causes are unapproved ingredients, health claims in titles or descriptions, and misrepresentation issues on the site, such as unclear contact, shipping or return information.

Is Shopping or Search better for supplement brands?

Shopping usually drives most profitable revenue because buyers compare products and prices visually. Non-brand Search adds high-intent demand. Both work best with brand traffic separated.

How do fitness brands lower CPCs on Google Shopping?

Better feed titles, segmentation by performance, strong negative keywords, and using a non-default CSS in Europe. Thyssen CSS offers up to 20% more efficient Shopping CPCs.

How fast can a supplement brand scale on Google Ads?

It depends on starting point, margins and markets. Scanfarma grew revenue by 200% over 14 months through steady, disciplined optimisation rather than sudden budget jumps.

Should supplement brands bid to ROAS or POAS?

Where product costs are known, POAS, because margins between own-brand and resold products differ a lot. It keeps budget on products that actually make money.
