Meta vs. Google Ads: Which Dietary Supplement Ads Survive?
Content
If you advertise dietary supplements, you’ve likely faced bans, rejected campaigns, or limited traffic – often without clear explanations. The reality is that Meta and Google enforce very different rules when it comes to this product category. In this article, we’ll provide a point-by-point comparison of both platforms, share real-world examples, and guide you on how to prepare your ads and website to successfully pass automated reviews and achieve long-term success.
1. Claims About Effects: What Can You Say?
One of the most frequent reasons dietary supplement ads get blocked is the way their effect claims are worded. Both Meta and Google exercise extreme caution regarding language that promises health or medical results, since such claims are regulated under laws governing medicinal products.
There are two main risks:
- Absolute claims – statements that sound like guarantees or direct solutions to a problem.
- Medical claims – mentioning or implying treatment, relief, or prevention of disease/condition.
| Risky Examples | Safe (Compliant) Formulations |
|---|---|
| “Cures insomnia” | “Supports sleep” |
| “Eliminates anxiety” | “Maintains a sense of calm” |
| “Heals depression” | “Ingredients associated with metabolic activity” |
| “Lose 5 kg in 7 days” | “Formula designed for an active lifestyle” |
| “Boosts metabolism by 300%” | “Supports focus and concentration during the day” |
| “Eliminates joint pain” | “Contains vitamins and minerals contributing to normal immune function” |
These phrases trigger automated platform filters as “Misleading health claims” (wellness claims that do not promise direct treatment but highlight supportive or general strengthening effects).
Important: Google requires that even “softer” health claims be supported by scientific evidence from reputable sources such as PubMed, EFSA, or FDA. On the other hand, Meta does not require direct links to studies but will block any claims that sound overly promising or guaranteed, maintaining a cautious approach to health-related advertising.
Pro tip:
It’s important to avoid using verbs in the present tense that imply absolute results, such as “cures” or “eliminates.” Instead, opt for softer phrases like “supports…,” “helps with…,” or “associated with…” to stay compliant. Always review your landing page carefully for risky claims, as any mismatch between your ad and website can lead to ad blocks. Additionally, avoid using medical terminology, including diagnoses or disease names, within your ad copy to minimize risk.

2. Ingredients: What Is Allowed?
Meta and Google don’t just scan your ads – they automatically review your entire website, including landing pages, product descriptions, blog posts, and even images, to detect any mentions of banned or restricted ingredients that could lead to ad disapproval or account restrictions.
They do this via:
- Text scanning – algorithms recognize ingredient names in HTML.
- OCR (Optical Character Recognition) – even if the ingredient name is on an image.
- Contextual recognition – if a photo shows packaging with a label, AI can “read” its contents.
Allowed vs. Banned Ingredients
| Platform | Banned / Restricted Ingredients | Allowed (Safe Zone) Ingredients |
|---|---|---|
| Meta | CBD (even without THC), Yohimbine, DMAA, DHEA, HCG, SARMs | Magnesium, Zinc, Selenium, Vitamins A, B, C, D, E, Adaptogens (ashwagandha, rhodiola, ginseng), Probiotics, Enzymes, Omega-3 fatty acids, Turmeric, Ginger (with moderate claims) |
| Everything banned by Meta plus Synephrine (Bitter orange extract), Ephedrine/Ephedra, Kava kava, Kratom, Pro-hormones, Hormonal precursors | Only ingredients with “GRAS” (Generally Recognized as Safe) status |
Important: Even if you promote a “clean” product, having another product that contains banned ingredients anywhere on your website – including within blog posts or PDF documents – can result in Google blocking your entire advertising activity. While Meta tends to be somewhat more flexible, it can also halt campaigns in response to complaints or during manual reviews.
How to protect yourself:
- List all ingredients across your products to have a clear overview.
- Cross-check your ingredients against official lists such as Meta Prohibited Content and Google Dangerous Products.
- Use alternative formulations where possible – for example, “hemp seed oil” is allowed, whereas “CBD” is banned.
- Promote “grey zone” ingredients only through organic content or email marketing, avoiding paid ads for these substances.
- For campaigns on Google Shopping, make sure to also review the Merchant Center Policies for compliance.
3. Visual Content: What Does AI See?
Meta and Google no longer depend solely on human reviewers for ad approval. Instead, they employ AI algorithms that scan images to identify prohibited elements. These technologies include image recognition, which detects objects, faces, and bodies; OCR (Optical Character Recognition), which reads text embedded within images; emotional analysis, which identifies overly dramatic or “shocking” facial expressions; and contextual comparison, which assesses whether the visuals support or contradict the accompanying text.
Prohibited and Allowed Visual Content
| Platform | Prohibited / Restricted Visuals | Allowed (Safe Zone) Visuals |
|---|---|---|
| Meta | Before & after photos, close-ups of problem areas (belly, thighs, face), extreme transformations, images with claims like “Guaranteed” or “Fat Burner,” shocking or despairing facial expressions | Lifestyle shots with product, people in motion (sports, walking, work), neutral or positive expressions, food/drinks/ingredients in natural settings |
| Everything banned by Meta plus overly “perfect” bodies heavily retouched, medical images (X-rays, anatomical charts), symbols or text implying medical results | Product shots in context (kitchen, gym, office), minimalistic product photos, scientific graphics without effect promises |
Important: Even a small icon or text embedded in an image, such as “Lose 5kg”, can trigger automatic ad blocks. The AI systems are capable of detecting Cyrillic script, so simply changing the alphabet or font style will not bypass the filters. Meta is particularly strict when it comes to personal visual transformations, including alterations like wrinkle removal or addition, which are closely monitored and often flagged.
How to prepare safe visuals:
- Use real people in natural settings rather than overly “model-like” poses.
- Show the product in use but avoid highlighting specific “problem areas.”
- Include contextual scenes, such as the product on a desk, in the kitchen, or at the gym.
- When adding text to images, keep it informative (e.g., “With magnesium and vitamin B6”) without making any promises about results.
- Test your images using AI moderation tools like the Meta Creative Preview Tool before publishing to minimize the risk of rejection.
4. Ad Text (Copywriting)
Formulating effective ad copy is a common challenge for advertisers of dietary supplements. While Meta and Google differ in their levels of sensitivity, both platforms block claims that lack proper support or that sound like medical advice, ensuring that advertisements comply with their strict health-related policies.
Prohibited and Allowed Formulations
| Platform | Prohibited / Restricted Formulations | Allowed (Safe Zone) Formulations |
|---|---|---|
| Meta | Personal appeals: “Do you have trouble sleeping?”, “Feeling tired?”, absolute claims: “Eliminates insomnia”, “Cures anxiety”, promises of results in a timeframe: “Lose 5 kg in a week” | “Supports relaxation after a long day”, “Contains ingredients associated with energy and focus”, “Formula with magnesium and adaptogens for a balanced lifestyle” |
| Unsupported claims: “Boosts metabolism by 300%”, medical terms for diagnosis or treatment: “Cures depression”, “Migraine therapy” | “Ingredients with scientifically proven presence in traditional medicine”, “Supports normal immune function”, “Supports active lifestyle” |
Important: Meta frequently blocks ads even when problematic text appears solely on the landing page, rather than in the ad copy itself. In contrast, Google tends to allow more flexibility, permitting claims as long as they are supported by scientific research or regulatory approval. Overall, the safest strategy is to use moderate and descriptive language to minimize the risk of rejection.
How to write safely:
- Replace medical terms with general, sensation-based descriptions (e.g., use “supports sleep” instead of “cures insomnia”).
- Focus on ingredients and their benefits, rather than making guaranteed claims.
- Use qualifiers such as “may,” “supports,” or “associated with…” to soften assertions.
- Ensure your ad text aligns closely with the landing page content, as discrepancies often lead to ad blocking.
- Include a clear disclaimer on your website stating: “This product is not intended to diagnose, treat, cure or prevent any disease.”
5. Common Mistakes and Consequences
Even the best products and professionally crafted ads can fail if they violate Meta’s or Google’s advertising policies. Often, ad blocks are not triggered by obvious violations but by small details that the platforms’ algorithms detect automatically, underscoring the importance of meticulous compliance.
Table: Mistakes, Consequences, and Prevention
| Mistake | Consequence | Prevention |
|---|---|---|
| Overpromising in text | Ad rejected or account restricted | Use moderate, descriptive phrases (“supports,” “helps”) instead of absolute claims (“cures,” “guarantees”) |
| Ingredient in grey zone (e.g., CBD) | Campaign blocked or account under review | Check banned ingredient lists per platform before launching ads |
| Mismatch between ad text and landing page | Account restricted due to “misleading post-click experience” | Ensure full sync between ad text, visuals, and website content |
| Missing GDPR banner or misconfigured cookies | Meta/Google Pixel cannot collect data → poor optimization, lack of results | Install a cookie consent banner informing and collecting marketing pixel consent |
| “Before and after” images or exaggerated visuals | Automatic ad rejection, sometimes account block | Use lifestyle and product photos without dramatic transformations |
| Text in image with risky words | Ad fails review | Check visuals for hidden text with OCR tests before publishing |
Additional Risky Situations:
- References to medical studies not published in recognized sources.
- Use of UGC (user-generated content) where customers make prohibited claims.
- Excessive emotional triggers in copy (“Do you suffer from…”), especially on Meta.
Prevention Tips:
Before launching each campaign, it’s essential to conduct an internal pre-check using a comprehensive checklist to ensure compliance. Maintain archives of your ads so you can demonstrate adherence to policies in case of disputes. Regularly monitor updates to Meta’s and Google’s advertising rules, as these platforms frequently change their policies without prior notice. Additionally, test your content organically first – posting it outside of paid ads – to see if it gets flagged, helping you avoid issues before investing in paid campaigns.
6. How Platform Algorithms “See” Your Ads
Many advertisers assume that ad reviews are primarily conducted by humans, but in reality, 90% of initial checks are performed by AI. Meta and Google use a combination of advanced technologies including OCR (Optical Character Recognition) to detect risky words even within images; image recognition to identify faces, bodies, emotions, and contextual elements; content matching to compare ad text with website content; and ingredient scanning to detect substances mentioned in both images and text formats, including PDFs.
Tip: Before publishing your ads, make sure to scan your images using free OCR tools and test your landing page with the Google Ads Policy Checker to reduce the risk of rejection.
7. Often Overlooked Rules
Some requirements are commonly missed but can cause automatic blocks:
- Missing or incomplete disclaimer – especially important for health products.
- Missing contact details – Google requires a real address, phone, and email on the site.
- Unsupported language in the target country – if targeting Germany, your site must be in German or have translations.
- Hidden pages with risky products – even if not advertised, their presence is problematic.
8. How to Prepare Your Website for Ad Approval
Before launching an ad, it’s crucial to review all text content thoroughly, removing any medical or absolute claims that could trigger policy violations. Carefully check your product ingredients, and either remove or rephrase any risky substances to ensure compliance. Make sure to add a GDPR-compliant banner that obtains explicit consent for marketing cookies. Update your website’s footer to include essential pages such as the Privacy Policy, Terms & Conditions, Disclaimer, and accurate contact information. Finally, ensure that the messaging in your ads is fully synchronized with the text on your landing pages, maintaining consistency to avoid misleading users or triggering ad blocks.
9. What to Do If Your Ad Gets Blocked
- Check the rejection reason in Ads Manager – Meta and Google usually provide brief but sometimes vague explanations.
- Edit your ad by modifying or removing the risky word, image, or claim causing the block.
- Request a review – if the block resulted from an algorithmic error, human reviewers may approve your ad upon re-evaluation.
- Use split testing to run multiple versions of the same ad and identify which one passes the review more easily.
- Consider alternative marketing channels such as email marketing, SEO, and influencer campaigns to offset potential traffic losses from restricted ads.
Conclusion
Advertising dietary supplements on Meta and Google is entirely feasible, but it demands a strategic approach. This includes using careful language, avoiding medical claims, and making overly promising statements. You must ensure full compliance with banned ingredients, even if they’re not the product’s main components. It’s equally important to review visual content for transformations, risky words, or potentially misleading images. Additionally, prepare your website thoroughly, ensuring it meets all legal requirements and provides clear transparency to users.
The truth is: Meta enforces rules based on what you say and show, while Google focuses on what you sell and how you substantiate it.
