Supplement Stack Risk Checker

Most people’s supplement cupboard grows one impulse at a time, and things quietly start working against each other - two magnesiums, three stimulants, a sedative stack, or something that really needs a blood test first. Tick what you take and this gives you a cautious sense of what to look at before buying anything else.

This is a rough flagging tool, not a real interaction checker. It can’t see doses, your medicines, or your medical history, and it doesn’t catch every interaction. Always confirm combinations with a pharmacist or your GP - that’s free and they’re good at it. Never start or stop prescription medication based on this.

What do you take?

This is only a rough flag, and a real stack changes over time. The Club will let you save your stack, re-check it, and separate low-risk products from clinician-only topics.
