Weight Loss Supplement Safety: A Practical Checklist
Supplements in this category are generally safe for healthy adults — but "generally" hides real risks: undisclosed stimulants, laxative ingredients, interactions with medication.
Before you buy
- Read the actual ingredient list. If the vendor does not publish one, that alone is a caution signal in our data.
- Check for stimulants. Caffeine, yohimbine and senna (a laxative) are common — and not for everyone.
- Check the refund policy. A long published window (90–365 days) is a strong trust signal; no policy at all is a documented red flag.
- Watch for auto-ship clauses. Hidden subscriptions are the most common complaint in this category.
- Ask a professional. If you take medication or have a condition, no website checklist replaces medical advice — including ours.
How we surface safety data
Our legitimacy pages run a fixed red-flag checklist on every product: fake countdowns, auto-ship, no refund policy, undisclosed subscriptions and exaggerated claims — with the evidence for each.
