“Suppie cuts through the hype and helps you make smarter, more confident supplement choices.”
Shona Wilkinson, RNutrRegistered nutritionist. Former Head Nutritionist at Tesco.Supplement labels don’t tell the whole story.
A label lists what’s in the bottle. It can’t tell you whether the dose works, whether it’s safe with your medication, or what the fillers are doing there.

InteractionsEvery report flags known interactions with common medication.
TalcHigh risk
A flow agent in tablets. The concern is asbestos contamination in poorly sourced talc.
Tartrazine (E102)Medium risk
A synthetic yellow dye that must carry a warning about children’s attention in the EU.
Silicon dioxideLow risk
An anti-caking agent, generally considered safe at supplement doses.
Many are poorly formulated
Doses far above or below the studied range, forms the body struggles to absorb, or ingredients with little research behind them.
The risk is on the back
Turn this B6 bottle around. Each tablet holds 100 mg, over 8× the EU’s safe daily upper limit of 12 mg. Taken for months, doses like this are linked to nerve damage.
Safety risks hide in plain sight
Even the most common supplements can interact with medication. St John’s wort, a herbal remedy for low mood, can make the contraceptive pill less effective.
Fillers carry risk too
Additives and inactive ingredients are the part of the label almost nobody reads. Suppie rates every one of them.
From label to verdict in seconds.
Suppie reads every line of the Supplement Facts panel and checks it against published research from sources like PubMed and the NIH.

Questions
Why not just ask ChatGPT?
Chatbots are good for broad questions, but answers change with how you phrase them and sources can be hard to check. Suppie is built only for supplements: it scores the exact label with one published rubric, cites its sources, remembers your stack, goals and allergies, and helps you keep a routine.
Is Suppie medical advice?
No. Suppie explains published research and label data so you can have a better conversation with your clinician. It doesn’t diagnose or treat anything. If you take prescription medicine, check with your GP before changing your routine.
Where does the evidence come from?
Suppie researches each product live, comparing its doses and forms with the formulations used in published studies, drawing on sources including PubMed and the NIH Office of Dietary Supplements, alongside the product’s own label. That’s why it works on any supplement, not just a fixed database. Every report lists its sources so you can open them yourself.
How we scoreDoes Suppie test what’s in the bottle?
No. Suppie analyzes what the label declares against published research. It doesn’t lab-test physical bottle contents.
Can brands pay for a better grade?
No. Brands can’t pay to be listed, raise a grade or change a score; every product runs through the same rubric. Suppie is funded by subscriptions and isn’t paid by the brands or retailers behind the products it grades.
How does the free trial work?
New members get full access free for 3 days: unlimited scans and chats, your Stack and Suppie Coach. If Suppie isn’t for you, cancel anytime in your iPhone’s Settings before the trial ends and you won’t be charged. Otherwise your annual plan starts on day 3.
Is Suppie on Android?
Not yet. Suppie is iPhone only today.
How is Suppie different from Examine?
Examine summarizes the research on ingredients, which is excellent for learning whether magnesium helps sleep. Suppie grades the specific product in your hand: every active and inactive ingredient, its doses, fillers and interactions, in seconds.
