Your Guide to UK Health and Wellbeing Paid Media Compliance

Paid media is one of the most profitable digital marketing strategies for health and wellbeing brands, returning 5 times more on average than you invest.

But that doesn’t mean you can throw money at social and search ads just expecting to grow. Not only do you need eye-catching creative, compelling copy and precise targeting to maximise your return on investment (ROI), but you also need to meet strict compliance rules.

These come in two types:

• Legal compliance: Standards set out by law
• Platform compliance: The advertising criteria of your ad platform

Fail to meet these requirements, and your ads might not be allowed to run.

Worse still, violating them means you could have your ad account banned.

So you can wave goodbye to that 500% ROI – which could be a lot more with a first-rate paid media strategy.

That’s why health and wellbeing brands across the UK rely on Fueld for safe and compliant paid media growth. With a wealth of digital advertising experience and a history of consistent paid media success, we maximise your online sales while keeping costs low.

What counts as a medicinal claim?

Paid media for health and wellbeing focuses on promoting products and services that make people’s lives better.

But there’s a fine line between what counts as ‘lifestyle’ and what counts as ‘medicine’.

According to the Advertising Standards Authority (ASA):

A medicinal claim is a claim that a product or its constituent(s) can be used with a view to making a medical diagnosis or can treat or prevent disease, including an injury, ailment or adverse condition, whether of body or mind, in human beings and, where relevant, animals.

The moment you imply a product or service can treat, prevent or diagnose a medical condition, you move out of lifestyle marketing and into medical regulation. In this space, rules are much more strict.

So while “supports relaxation” is a fairly safe non-medical claim, saying a product “reduces anxiety symptoms” attracts a lot more regulatory scrutiny.

This doesn’t just apply to pharmaceuticals, either. In an advertising context, these rules are relevant for:

• Medicines
• Devices
• Foods and supplements
• Cosmetics
• Therapies

How does that affect paid media for health and wellbeing brands?

Regulators and digital platforms review your paid media campaigns at an ad level. So even if a product or service meets the threshold for medicine, your paid social, pay per click and programmatic ads can still be non-compliant.

This doesn’t just apply to explicit claims like “treats insomnia”. It also concerns implicit claims about:

• Treatments: “Finally fix your sleep cycle”
• Conditions: “Struggling to fall asleep?”

Regulators and advertising platforms interpret both the words you use and how potential customers might understand those words.

In paid media, where ads are often short, punchy and benefit-led, this creates a much greater risk of overclaiming. That’s doubly true in scaled campaigns that can include hundreds of variations, especially when AI tools aren’t properly monitored.

As experts in paid media for health and wellbeing, Fueld’s digital advertising team crafts compliant ads that perform effectively and protect you against enforcement. So when you get in touch to discuss your next campaign, you can have confidence that your digital ads will meet legal and platform requirements.

UK health and wellbeing paid media compliance map

Once you make a medicinal claim, you’re not just dealing with one rulebook. There are multiple compliance bodies to consider, as well as your ad platform. And unless you understand their requirements in full, a single phrase can put you at serious risk.

Regulatory bodies governing legal compliance

ASA and CAP: Standards and consumer protection

The ASA is an independent regulator largely concerned with monitoring and banning ads. As part of its duties, it enforces strict rules around substantiating medicinal claims, requiring robust clinical evidence that matches what advertisers are saying.

Its sister organisation, the Committee of Advertising Practices (CAP) is responsible for writing the Advertising Codes. These ‘CAP Codes’ feature a rulebook for non-broadcast advertising, sales promotions and direct marketing communications.

As well as general rules on misleading ads and use of data, the CAP Codes include specific chapters for:

• Chapter 12: Medicines, medical devices, health-related products and beauty products: These rules cover evidence levels of medicinal claims, suitable qualifications for those claiming to treat, medicines rules, herbal and homeopathic product rules, cosmetics, and hair growth and loss

• Chapter 13: Weight control and slimming: Rules for the content and targeting of ads concerning weight control, slimming foodstuffs and aids (including exercise), diets, clinics and medicines

• Chapter 15: Foods, food supplements and associated health or nutrition claims: Relating to health and nutrition claims in foodstuffs, vitamins, minerals, infant and follow-on formula, and food and soft drinks marketing to children

MHRA: Product classification and licensing

The Medicines and Healthcare products Regulatory Agency (MHRA) is the UK government body responsible for ensuring medicines and medical devices are safe and effective.

As well as evaluating new medical treatments, the MHRA also produces the Blue Guide for Advertising and Promotion of Medicines in the UK. This includes:

• Chapter 2: The legislative framework: Describes UK legislation that regulates the advertising of medicines and provides definitions or terms used

• Chapter 4: General rules: Sets out the general rules for advertising medicines

• Chapter 5: Advertising to the public: Explains legal requirements and restrictions for advertising to the public, including patient and consumer safety

• Chapter 6: Advertising to persons qualified to prescribe or supply medicines: Provides guidance on the advertising of prescription-only and over-the-counter medicines, targeting healthcare professionals

GB NHC: What you can and can’t say

Very slight changes in wording can give people different expectations for your products. To ensure consistency and transparency, the Great Britain Nutrition and Health Claims (GB NHC) register specifies what you’re legally allowed to say.

Brands that sell food, drink and supplements in the UK can only use pre-approved health claims found on the GB NHC’s register of approved claims. For each entry, this register specifies:

• Claim type
• Nutrient substance, food or food category
• Claim
• Conditions and restrictions of use of the claim, or reasons for non-authorisation
• Health relationship
• Scientific opinion reference
• Regulation
• Authorisation status
• Entry ID

Based on these authorised claims, you could claim that “selenium contributes to the maintenance of normal hair”.

But you can’t say:

• Selenium strengthens your hair
• Supports healthy hair
• Get thicker, fuller hair
• Struggling with hair loss?
• Essential for healthy hair

This presents a challenge to paid media marketing. That’s because trying to fit health claims into the smallest possible space could conflict with permitted wording, putting you at risk of non-compliance.

Policies for advertising platforms

Google Ads

As with all advertising platforms, Google Ads follows advertising regulations for healthcare and medicine. But the platform also uses internal policies to determine whether your ad is allowed to run.

With millions of campaigns running at once, Google can’t check every ad manually. Instead, each ad goes through machine-led review before it runs to evaluate:

• Headlines
• Descriptions
• Keywords
• Display URL
• Landing page content (which is why SEO content writing is essential)
• Intent and meaning, not just words

Google wants to approve ads quickly while ensuring compliance. So these automated reviews are usually very strict. Even small changes in wording can trigger disapproval, which is why similar ads can get different outcomes.

If something doesn’t match their internal policy, Google can:

• Disapprove individual ads
• Limit ad delivery
• Restrict certain content
• Suspend your account in severe or repeated cases

The risks and cost for ad disapproval are high, especially if you’re running ads without paid media expertise. That’s why it’s essential to work with an experienced ad agency that can deliver compliant, high-converting ads quickly.

Meta ads

The Meta Transparency Center offers clear guidance on what ads for Facebook, Instagram and other platforms must not include, with relevant exceptions.

To make the rules even easier to understand, they have separate pages for different industries, such as:

• Health and wellness: Covers both ‘Weight Loss and Cosmetic Products and Procedures’ and ‘Adult Products and Reproductive Health’. Neither may be promoted to people under 18 years old, with exceptions such as fitness services or general food products. And ads must not imply or generate negative self-perception
• Drugs and pharmaceuticals: Specific requirements for prescription drugs, over-the-counter medicines and cannabis-derived products

Meta’s Advertising Standards internal policy framework controls which ads can run in their network. And like Google, each ad is reviewed using machine learning to assess your ad, landing page and intent.

But the biggest difference is that Meta also focuses on personal attribution.

The platform has a strict rule that ads must not assert or imply personal attributes about the user. This include:

• Health condition: “Say goodbye to joint pain in just 7 days!”
• Mental health: “Feeling anxious lately?”
• Physical appearance: “Get rid of your wrinkles”
• Age, weight or body concerns: “Finally shed those extra pounds”

Where Google is focused on claims and wording, Meta is more concerned with personalisation and tone. And if your ads are repeatedly flagged, Meta can reduce the reach of your ads, send you warnings or even restrict your account.
