Supplement De-Influencing: Why We Built a Tool to Check What TikTok Won't Tell You

The #deinfluencing hashtag crossed 1 billion views on TikTok in 2023 and has since surpassed 3.5 billion total content views. It started as people saying "don't buy this" — and it was refreshing. After years of #TikTokMadeMeBuyIt hauls, someone finally said the quiet thing out loud: most of this stuff isn't worth your money.

But here's the problem nobody talks about.

De-influencing is still influencing. The format changed. The incentive structure didn't. A creator telling you not to buy AG1 while recommending their own code for a different greens powder isn't transparency — it's just marketing with a sceptical coat of paint. Research from MediaCat UK confirmed exactly this: de-influencing videos build trust in the creator, but don't actually change viewers' purchasing behaviour or brand perceptions.

Meanwhile, 74% of Gen Z users now think twice about who they engage with on TikTok, and 79% say they miss the pre-commercialised version of the platform. The trust is eroding — but the supplement recommendations keep coming.

I didn't build De-Influenced because I wanted to be a content creator. I built it because I personally needed it.

I'm Liz. I've worked in healthcare IT for over 20 years, and my partner works in frontline healthcare. Between us, we've seen how the gap between clinical evidence and consumer marketing plays out — and I've spent more money than I'd like to admit on supplements over the past decade.

Some of them were genuinely useful. Many of them weren't. And the problem was always the same: I couldn't tell which was which by looking at the label.

I'd see a product with 15 ingredients, four of them listed inside a "proprietary blend" with no individual doses, marketed by someone with a ring light and a discount code. I'd Google the product, and every review was either an affiliate post or a personal anecdote. Nobody was checking whether the ingredient doses matched the clinical research. Nobody was saying "this contains 50mg of ashwagandha, but the studies used 600mg."

So I started doing it myself. Manually. Pulling up labels, cross-referencing PubMed, checking clinical trials. And then I thought — why isn't there a tool that just does this?

That's what De-Influenced is. You paste a product URL and upload a photo of the ingredient label. The tool extracts the ingredients, checks every dose against clinical evidence, scores it for transparency, and surfaces alternatives that are cheaper and properly dosed. No affiliate links. No sponsored placements. No discount codes.

It exists because I needed it. And I suspect you do too.

"Nature's Ozempic" — The Berberine Myth

Berberine is currently the #1 selling supplement on UK TikTok Shop, with nearly 5,000 orders per week and over £815,000 in weekly revenue. It's marketed as "nature's Ozempic" — a natural alternative to semaglutide, the prescription GLP-1 drug that produces significant weight loss.

The clinical evidence tells a completely different story.

A 2026 randomised controlled trial published in JAMA Network Open — 337 participants, double-blind, placebo-controlled, across 11 hospitals — found that berberine at 1g daily for six months did not reduce visceral fat or liver fat content compared to placebo.

A 2025 systematic review of 23 RCTs found berberine reduced body weight by an average of 0.88kg and BMI by 0.48 points. For context, semaglutide (Wegovy) produces approximately 14.9% body weight loss at 68 weeks — that's roughly 15kg for someone starting at 100kg.

These are not remotely comparable outcomes. As the American Academy of Family Physicians noted, berberine "lacks rigorous evidence and has potential harms." Those harms include documented interactions with blood thinners, immunosuppressants, and diabetes medication — none of which are listed on the TikTok Shop product pages I've checked.

Berberine has legitimate research for blood sugar management in people with metabolic conditions. That's a real use case. But "nature's Ozempic" is not a clinical description — it's a marketing line designed to move units.

Collagen Gummies — The Dosing Problem Nobody Mentions

Collagen supplements are a £200 million+ UK market, and gummy formats are the fastest-growing segment. The appeal is obvious — they taste good and they're easy.

The problem is the dose.

Clinical trials showing benefits for skin hydration and elasticity consistently use hydrolysed collagen peptides at 2.5 to 10g per day. A 2024 RCT in the Journal of Clinical Medicine used 10g daily and found significant improvements in skin elasticity and hydration versus placebo. A systematic review of 26 RCTs involving 1,721 patients confirmed that hydrolysed collagen supplementation significantly improved skin hydration and elasticity — but the studies used doses of 2.5g to 10g daily.

Most collagen gummies contain 1–3g per serving. Some contain less. At the lower end, you're getting a fraction of the dose that the research actually tested. The gummy format itself is part of the problem — you physically can't fit 10g of collagen peptides into two gummy sweets without them being the size of golf balls.

This doesn't mean collagen is useless. It means the delivery format matters, and the dose matters, and "clinically studied ingredient" on the label doesn't mean "clinically studied dose in this product."

"Cortisol Face" and the Ashwagandha Rush

"Cortisol face" is not a medical diagnosis. It's a TikTok trend that claims everyday stress visibly puffs up your face — and that the solution is ashwagandha to lower cortisol.

Healthline reported what multiple dermatologists and endocrinologists have confirmed: the facial swelling associated with high cortisol (technically called "moon face") is a symptom of Cushing's syndrome, which affects approximately 10–15 people per million. It is not caused by normal everyday stress.

As Dr Gary Goldenberg, a board-certified NYC dermatologist, told Prevention: "Stress alone cannot cause cortisol face puffiness. This is typically caused by a medical condition."

Now, ashwagandha itself does have research behind it. A 2012 study in the Indian Journal of Psychological Medicine found that 300mg twice daily of KSM-66 ashwagandha root extract reduced serum cortisol by 27.9% versus 7.9% in the placebo group. A 2019 study in Cureus found that 600mg daily significantly reduced cortisol levels and improved sleep quality. Those are real findings with real methodological rigour.

But here's the critical detail: the studies used 300–600mg of a specific, standardised extract (KSM-66), measured over 8–12 weeks. Most TikTok-promoted ashwagandha products either don't disclose the extract type, don't disclose the dose, or contain it as one ingredient inside a proprietary blend where the actual amount could be anything from 50mg to 500mg. You simply cannot verify whether you're getting a clinically meaningful dose.

And even if the ashwagandha is properly dosed — it's being sold as a fix for "cortisol face," which isn't a real condition. That's a solution to a problem that doesn't exist, marketed to people who've been convinced they have it by a 30-second video.

The de-influencing movement diagnosed a real problem: people are being sold overpriced, underdosed supplements by creators who are financially incentivised to recommend them. That's accurate. That's important.

What it misses is the solution.

Telling people "don't buy this" without explaining why — without checking the dose, without citing the research, without comparing the alternatives — is just opinion dressed up as advice. It builds the creator's credibility. It doesn't build the viewer's knowledge.

The supplement industry doesn't need more opinions. It needs more transparency. It needs tools that let consumers verify claims independently, without trusting any single creator, brand, or reviewer.

That's what De-Influenced does. Not "trust me instead of them." Just: here's the label, here's the research, here's what the dose actually is, and here are the alternatives.

1. Paste a product URL and upload the ingredient label — any supplement sold online in the UK.
2. We extract the label — every ingredient, every dose, every blend.
3. We check it — doses are compared against published clinical research. Ingredient forms are scored (magnesium glycinate vs. magnesium oxide, for example). Proprietary blends are flagged.
4. You get a transparency score — a clear, numerical rating of how much the label actually tells you.
5. We show alternatives — products with comparable ingredients at clinical doses, sorted by price and quality tier.

What is supplement de-influencing?

Supplement de-influencing is a social media movement where creators advise against purchasing specific supplements — typically products promoted by influencers or through paid partnerships. The #deinfluencing hashtag has accumulated over 3.5 billion views on TikTok. While the intent is to counter overhyped marketing, the format still relies on individual creator opinion rather than systematic, evidence-based analysis.

Is berberine actually "nature's Ozempic"?

No. The clinical data does not support this comparison. Semaglutide (Ozempic/Wegovy) produces approximately 14.9% body weight loss in trials. A 2025 meta-analysis of 23 RCTs found berberine reduces body weight by an average of 0.88kg. A 2026 JAMA Network Open RCT found berberine did not reduce visceral fat versus placebo. Berberine has legitimate research for blood sugar regulation in metabolic conditions, but it is not comparable to GLP-1 agonists for weight loss.

How much collagen do you actually need for skin benefits?

Clinical trials showing significant improvements in skin hydration and elasticity used hydrolysed collagen peptides at doses of 2.5 to 10g per day. Most collagen gummies provide 1–3g per serving. Powder or liquid formats are more likely to deliver a clinically meaningful dose.

Does ashwagandha really lower cortisol?

Some evidence supports this. A 2019 study published in Cureus found 600mg daily of ashwagandha root extract significantly reduced serum cortisol levels versus placebo. A 2012 study found similar results at 300mg twice daily of KSM-66 extract, with a 27.9% cortisol reduction. However, not all ashwagandha products contain the same extract, dose, or standardisation — and "cortisol face" is not a recognised medical condition.

Is De-Influenced free?
