Supplement audit
Stop guessing whether your supplements are worth it.
A vitamin D because your GP mentioned it. A fish oil because your mum takes one. A multivitamin because it seemed sensible. Here's how to find out, honestly and for free, what's actually worth keeping.
Most people never sat down and planned their supplements. They arrived one at a time: a pharmacist's suggestion, a friend's tip, a news article, a habit from years ago that never got a second look. Now there are five or six things in the cupboard and no real idea whether any of them are doing much.
That's an easy way to end up paying for supplements you don't need, at doses that might not be right either way. Nobody sits you down and checks. There's no moment where someone says "actually, you can stop buying that one."
You don't need to book a GP appointment to get an honest answer, and it isn't a silly question to ask. Paste what you're currently taking into our free audit tool and see, in about ten seconds, which doses look low, which look high, and which items might not need to be there at all.
This page explains what that audit checks, and what Stack Almanac does next if you'd like help keeping track of your stack (that's just our word for "the supplements you take") properly, going forward.

You don't actually know if it's working
You've taken the same handful of supplements for months, maybe years. No one's ever told you whether any of them are doing anything, and there's no easy way to check on your own.
You might be wasting money every month
A multivitamin, a fish oil, a magnesium, maybe a probiotic. It adds up to real money, and some of it could be entirely unnecessary for you specifically.
The doses might be wrong either way
Too little and it isn't doing much. Too much and it isn't helping either, sometimes it's the opposite. Most people have no idea which side of that line they're on.
It feels like an embarrassing question to ask
Turning up to your GP or pharmacist with a carrier bag of supplements and asking "is any of this worth it" feels silly. It isn't. But we get why you'd rather check quietly first.
How Stack Almanac helps
Start with the free audit, no signup needed
Paste your routine into our audit tool and get an instant, plain-English read on your doses and timing. No account and no email required, and nothing is saved unless you ask us to send you the results.
See what you're actually spending
Stack Cost & Savings adds up your monthly spend across everything you take, and shows a realistic figure for what you could save by switching to the cheapest reliable source for each item.
Never run out, never overbuy
Smart Restock tracks how much of each supplement you've got left, warns you before you run out, and gives you a one-tap link to the best price when it's time to reorder.
Ask a plain question, get a plain answer
Not sure if you actually need something you're taking? Ask the Almanac Advisor. It answers like a sensible friend who's read the label, not a wall of jargon.
Log only when something changes
No daily checklists. Tell us if you skip something or swap it out, and we'll keep the picture current. Built for people who already take supplements inconsistently, which is most people.
