# Supplement ad prompts, tested on one bottle Source: https://storetoads.com/ad-prompts/supplements/ Supplement ads have two ways to go wrong: the bottle and the claims. We ran five common supplement ad prompts for Morrowleaf, a fictional magnesium brand, and checked each result against its label and product page. The bottle came back close more often than in most categories. The claims are where the trouble was, including two numbers printed on the label that would mislead anyone counting doses. *Updated October 17, 2026. Every prompt ran once on October 17, 2026, for a fictional brand. Nothing was retried or cherry-picked.* ## What is a safe AI prompt for a supplement ad? Attach your real bottle photo and tell the model the label stays exactly as printed. Give the dose, count and price word for word, and write every line of text yourself. Never ask the model for benefits: in our test it added sleep and stress claims and printed 500 mg on a 200 mg label. ## The five prompts, run for real Morrowleaf · Magnesium Glycinate, 120 Capsules · $28 (was $34) · 4.8 from 2,141 reviews · fictional Morrowleaf's product page: Magnesium Glycinate, 120 vegan capsules, 200 mg of elemental magnesium per two-capsule serving (48% Daily Value), 60 servings, third-party tested, no fillers or artificial colours, amber glass bottle, $28 (was $34), rated 4.8 from 2,141 reviews. The page makes no sleep or stress claims. Two prompts below ask for them anyway, because that is how many owners write supplement prompts. A to C had no photo; D and E had the packshot attached. ![Morrowleaf's product photo: Magnesium Glycinate, 120 Capsules, the packshot attached to prompts D and E.](https://storetoads.com/samples/morrowleaf.webp) ### Prompt A: The "sleep better" wellness prompt *ChatGPT-style prompt, no photo.* Product facts plus the benefit the owner hopes for ("help people sleep better and feel calm"): the most common way a supplement prompt is written for ChatGPT. > Create a clean wellness Instagram ad for my supplement brand MORROWLEAF. Product: Magnesium Glycinate, 120 vegan capsules, 200 mg magnesium per serving, third-party tested, no fillers, amber glass bottle. Price $28 (was $34). Help people sleep better and feel calm. Include the brand name, product name, price and a "Shop now" button. Calm, natural, premium. ![AI output for the first prompt: an amber jar with a black lid and a cream and green label reading Morrowleaf Magnesium Glycinate, under the headline Sleep better. Feel calm., with four product points, $28 was $34, a Shop now button, four badges and a small FDA disclaimer at the bottom.](https://storetoads.com/prompts/supplements/A.webp) *Made with GPT-5.4 Image 2 (OpenAI, through the OpenRouter API), October 17, 2026, for a fictional brand.* Product changed · Text errors: 0 · Unasked details: 2 **What went right** - 120 vegan capsules, 200 mg per serving, third-party tested, no fillers, $28 and the struck-through $34 are all correct. - It added the standard FDA disclaimer under the sleep claim on its own, the one US supplement labels carry next to structure and function claims. **What went wrong** - The sleep claim came from our prompt, and the model repeated it everywhere, including on the redrawn label: "Supports relaxation, promotes restful sleep". Morrowleaf's real label says neither. - It added "Science backed" and "Highly absorbable". Both are claims that need evidence the page doesn't offer. - The label gained a dark green band and a new layout; the real one is plain cream with a leaf mark. **Could you run it?** Neat and nearly runnable, which is the risk: it turned a hopeful line in a prompt into claims on the product itself. ### Prompt B: The "better sleep, less stress" headline prompt *Gemini-style prompt, no photo.* Asking the model for a headline about sleep and stress plus three benefits: the pattern supplement prompt templates for Gemini push. > Generate a supplement advertisement for Morrowleaf Magnesium Glycinate ($28). Amber glass jar with a cream label, white capsules spilling out, a woman sleeping peacefully in the background. Write a catchy headline about better sleep and less stress, three benefits, "4.8 stars from 2,141 reviews" and the price. Soft, calming colors. ![AI output for the second prompt: a woman asleep in bed behind an amber jar labelled Morrowleaf Magnesium Glycinate, For Restful Sleep and Stress Relief, 500mg, 120 Capsules, under the headline Sleep deeper. Stress less. and three sleep and stress benefits, with 4.8 stars and $28.](https://storetoads.com/prompts/supplements/B.webp) *Made with Nano Banana 2 (Gemini 3.1 Flash Image) (Google, through the OpenRouter API), October 17, 2026, for a fictional brand.* Product changed · Text errors: 2 · Unasked details: 2 **What went right** - The rating and review count are exactly as given. - The jar is close: amber glass, black lid, cream label with the brand name. **What went wrong** - The label says "500mg". The real serving is 200 mg, and dose is the one number a supplement buyer must be able to trust. - Next to the price it says "120 capsules | 1 month supply". At two capsules a serving, 120 capsules last 60 days. - The benefits promise "uninterrupted sleep", "reduce stress levels" and "muscle relaxation", and the label now reads "For Restful Sleep & Stress Relief". None of it is on the product page, and there's no disclaimer. **Could you run it?** Do not run. Two wrong numbers and a row of health claims, on a bottle that otherwise looks right. ### Prompt C: The clean wellness keyword prompt *Midjourney-style keyword prompt, no photo.* "Supplement product photography" prompts: the label text in quotes, botanicals, linen and soft light. > supplement product photography, amber glass bottle with black lid, cream label reading "MORROWLEAF Magnesium Glycinate 200 mg per serving 120 vegan capsules", white capsules, eucalyptus leaves, linen, soft morning light, clean wellness aesthetic, photorealistic, 8k --ar 4:5 --style raw --v 7 ![AI output for the third prompt: an amber bottle with a black lid and a cream label reading Morrowleaf Magnesium Glycinate, 200 mg per serving, 120 Vegan Capsules, beside white capsules and eucalyptus on linen, with no ad text.](https://storetoads.com/prompts/supplements/C.webp) *Made with FLUX.2 Pro (Black Forest Labs, through Higgsfield), October 17, 2026, for a fictional brand.* Product changed · Text errors: 0 · Unasked details: 0 **What went right** - Every word on the label is right: MORROWLEAF, Magnesium Glycinate, 200 mg per serving, 120 Vegan Capsules. - It added no claims, because the prompt asked for a photograph, not copy. **What went wrong** - The label's typography differs from the real one: a larger, softer product name and a different leaf mark. - No price, headline or button. It is a photo you would still need to turn into an ad. **Could you run it?** The cleanest of the no-photo runs. Use it as a mood image if the label difference doesn't bother you. ### Prompt D: ChatGPT with the bottle photo *ChatGPT-style prompt with the product photo.* Upload the packshot, ask for a bedside scene and supply every line: the edit flow in OpenAI's help pages. > Here is my product photo. Turn it into an Instagram ad for my supplement brand Morrowleaf. Put the bottle on a bedside table with a glass of water and a few capsules, soft evening lamp light. Keep the bottle and label exactly as they are. Add the headline "200 mg magnesium. Nothing else.", "Third-party tested" and "$28 (was $34)". ![AI output for the fourth prompt: Morrowleaf's amber bottle with its cream label on a bedside table beside a glass of water and capsules in lamp light, under the headline 200 mg magnesium. Nothing else., with Third-party tested and $28 (was $34).](https://storetoads.com/prompts/supplements/D.webp) *Made with GPT Image 2.5 (OpenAI, through Higgsfield), October 17, 2026, for a fictional brand.* Product kept · Text errors: 0 · Unasked details: 0 **What went right** - The bottle and label match the packshot, small print included. - Headline, tested line and price are word for word, and the model added no claims of its own. **What went wrong** - One problem is ours, not the model's: "Nothing else" is a stronger claim than the page's "no fillers" (a capsule has a shell, for a start). The model printed it without a second thought, which is the point: it checks nothing. **Could you run it?** The model did its job well. The headline needed a human edit, and nothing in the tool would have flagged it. ### Prompt E: Gemini with the bottle photo *Gemini-style prompt with the product photo.* Keep the bottle, add a hand and a kitchen table: the lifestyle edit Nano Banana is asked for most. > Use this exact supplement bottle. Show a woman's hand holding two capsules over the open bottle at a sunny kitchen table. Do not change the bottle or the label text. Add the text "Magnesium Glycinate, $28" at the top. ![AI output for the fifth prompt: a hand holding two capsules over the open Morrowleaf bottle on a sunny kitchen table, with capsules scattered beside it and Magnesium Glycinate, $28 at the top.](https://storetoads.com/prompts/supplements/E.webp) *Made with Nano Banana Pro (Gemini 3 Pro Image) (Google, through Higgsfield), October 17, 2026, for a fictional brand.* Product kept · Text errors: 0 · Unasked details: 0 **What went right** - The label is intact: MORROWLEAF, MAGNESIUM GLYCINATE, 200 mg per serving, 120 VEGAN CAPSULES. - Two capsules, as asked, which happens to match the real serving. - The hand and the kitchen light look natural. **What went wrong** Nothing we could find. **Could you run it?** A clean lifestyle image with no claims in it. Pair it with facts you write yourself. ## What the five runs show for supplements Supplement bottles are simple shapes, and the models mostly kept them close. The real damage was in the words. Where the prompt mentioned sleep, the model put sleep claims on the label itself. Where it wrote its own benefits, it added stress relief and muscle relaxation, misstated the dose and turned 60 servings into a month's supply. Those aren't style problems. The FTC's guidance for health products expects claims like these to be backed by competent and reliable scientific evidence, and Meta's Health and Wellness standards add their own rules. A model that writes "reduce stress levels" for you leaves you holding the claim. With the packshot and our own lines, both models produced clean, accurate images. The lesson isn't to avoid the tools. It is to treat every word as yours, because the tools will print anything, including an overreach in your own headline.

It placed the packshot as it is and matched every number against the page before delivery. ### Morrowleaf: Everything on the label. Nothing that isn't. ![Dark green Morrowleaf ad: 'Everything on the label.

Fill each [bracket] with the words on your label and product page, exactly, and don't add benefits the page doesn't state. ### 1. The label facts ad The safest supplement ad there is: what's in it. ``` Use the attached photo of my supplement bottle exactly as it is: same bottle, lid and label, every word and number unchanged. Do not add any text to the label. Place it on [SURFACE] with [A FEW CAPSULES OR TABLETS]. Add only this text: headline "[INGREDIENT AND AMOUNT PER SERVING, as on my label]", line "[TESTING OR SOURCING FACT FROM MY PAGE]", price "[PRICE]". No benefits, badges or health claims. ``` ### 2. The routine ad When you want a lifestyle scene without a promise. ``` Keep the attached bottle photo unchanged. Place it in [A ROUTINE SETTING, e.g. a kitchen counter in morning light] next to [ONE EVERYDAY OBJECT]. No people's faces, no text, and nothing that suggests a result such as sleeping, energy or weight change. ``` ### 3. The review ad When customers talk about the product itself. ``` Use my bottle photo as it is, on the right third of a plain [COLOUR] background. On the left, set this review word for word: "[A REVIEW ABOUT TASTE, SIZE, PACKAGING OR INGREDIENTS]" and "[RATING] stars from [REVIEW COUNT] reviews". Do not edit the review. ``` ### 4. The claims check Before you download any supplement ad. ``` List every word and number in the image, on the label and around it. Mark anything that describes a health effect or a result, and any number that differs from this label text: [YOUR LABEL TEXT]. Then make a version with all of those removed and nothing else changed. ``` ## Tips for each tool, for supplements ### ChatGPT - Keep benefits out of the prompt. When ours said "help people sleep better", GPT-5.4 Image 2 printed the claim on the redrawn label. - With the packshot attached, GPT Image 2.5 reproduced the label exactly. It will also reproduce any overstatement in your headline, so edit that first. - It may add a disclaimer on its own, as ours did. A disclaimer doesn't make an unsupported claim acceptable; remove the claim instead. ### Gemini - Never ask it to write supplement benefits. Our Nano Banana 2 run invented three and changed the dose on the label. - For lifestyle shots, attach the bottle and keep the scene neutral. Our Nano Banana Pro run kept every word on the label. - Read every number at full size: mg, capsule count, servings. That is where our runs went wrong, not the brand name. ### Midjourney-style tools - A photography prompt with the label text in quotes produced a clean label and no claims in our run. - The --ar and --style flags are Midjourney parameters, read at the end of the prompt per its docs; FLUX ignored them. - Avoid scenes that imply results, such as a person asleep or exercising; they can say more than your label does. ## Questions about supplement ad prompts **Can ChatGPT make a supplement ad?** Yes, and quickly. From our description it made a tidy ad with the right dose and price, then printed a sleep claim on the redrawn label because our prompt mentioned sleep. With the bottle photo and our own lines, GPT Image 2.5 made an accurate, claim-free image. **What are the health and wellness policies of Meta ads?** Meta's Advertising Standards include a Health and Wellness section with rules for supplements and health claims, and its personal attributes rule bars ads that assert or imply things about the viewer's health. Read the current text before running results-based claims; the links are in the sources below. **Why did the AI add sleep and stress claims to my ad?** Because the prompt invited them, either directly or by asking for benefits. Image models write what sounds like a supplement ad, and supplement ads often promise results. If your page doesn't make a claim, your prompt shouldn't mention it. **Do supplement ads need the FDA disclaimer?** US supplement labels carry the FDA disclaimer next to structure and function claims, and GPT added it to our ad unprompted. For advertising, the FTC's Health Products Compliance Guidance is about substantiation: claims need competent and reliable scientific evidence, and a disclaimer is not a substitute. **What is a good slogan for a supplement brand?** One that states a checkable fact: the amount per serving, how it's tested, what isn't in it. "Everything on the label. Nothing that isn't." works because the label proves it. Slogans that promise outcomes are where policy and legal problems start. **Can you give examples of ads about health products?** Ingredient callouts, a short-label myth and fact, a customer review about the product itself, a subscription price. Each is shown on this page as an engine-made Morrowleaf ad, and none needs a health claim. **How can I advertise my supplements on Facebook effectively?** Lead with what's verifiable (dose, testing, ingredients, price), allow time for ad review, and keep results out of the copy unless you can substantiate them. Our guide to advertising supplements covers channels, a starting budget and policy reviews. **Is it safe to let AI write supplement ad copy?** Not without checking every word. In our runs the model added three health claims, a wrong dose and a wrong supply length. Write the copy from your label and product page, and use the tool only for the image. **Will Meta label a supplement ad made with AI?** Possibly. Meta says it uses industry signals such as C2PA metadata to detect ads made or edited with outside generative AI tools and can add AI info to them. That label is separate from health policy review. **Which prompt should I start with?** The label facts ad in the pack above, with your packshot attached. It gives the image model nothing to invent: the amount per serving, a testing fact and the price, all copied from your own page. ## Sources Checked October 17, 2026: - [OpenAI Help Center: Images in ChatGPT](https://help.openai.com/en/articles/11084440-images-in-chatgpt) - [Gemini Apps Help: Generate & edit images with Gemini Apps](https://support.google.com/gemini/answer/14286560) - [Midjourney Docs: Parameter List](https://docs.midjourney.com/hc/en-us/articles/32859204029709-Parameter-List) - [FTC Health Products Compliance Guidance (December 2022)](https://www.ftc.gov/business-guidance/resources/health-products-compliance-guidance) - [Meta Advertising Standards: Health and Wellness](https://transparency.meta.com/policies/ad-standards/restricted-goods-services/health-wellness/) - [Meta Advertising Standards: Privacy Violations and Personal Attributes](https://transparency.meta.com/policies/ad-standards/objectionable-content/privacy-violations-personal-attributes/) - [Meta Business Help Center: About AI info on ads created or edited with generative AI tools](https://www.facebook.com/business/help/1010479435004531) ## Where to go next - [Ad prompts, tested](https://storetoads.com/ad-prompts/): 75 product ad prompts run in GPT, Gemini and FLUX for 15 fictional brands, every output marked for what went wrong, plus prompts that start from your photo. - [Supplement ad ideas](https://storetoads.com/ad-ideas/supplements/): Seven sample ads for a magnesium brand that sell the label, not a cure, plus Meta's 18+ rule and FDA claim limits. - [How to advertise supplements](https://storetoads.com/how-to-advertise/supplements/): A rules-first plan for a small supplement brand: adults-only Meta, a reorder email, then Shopping, with the claims each channel accepts. - [Skincare ad prompts](https://storetoads.com/ad-prompts/skincare/): Five skincare ad prompts run for one vitamin C serum: an invented before-and-after, unearned badges, and two runs that got it right. - [Pet product ad prompts](https://storetoads.com/ad-prompts/pet-products/): Five dog treat ad prompts run in GPT, Gemini and FLUX: the pouch, the spelling and the eco and natural claims, marked one by one. - [Food product ad prompts](https://storetoads.com/ad-prompts/food/): A hot sauce run through five food ad prompts in GPT, Gemini and FLUX: the label, the cap and the recipe claims, marked one by one. - [Pricing](https://storetoads.com/pricing/): Free preview, Starter $49/month, weekly plans from $99/month with a 7-day free trial, 30-day money-back guarantee. --- StoreToAds: StoreToAds is an AI ad generator for Shopify and DTC brands: your real product photo, never redrawn, every price and review checked, fresh ads every week.
