60-second game

Myth or fact? Flip three cards.

Three things most people get wrong about their supplements. Every card you flip can add to your stack.

Sample stack, real analysis

Not medical advice.

Nine items we typed in once, most of them at breakfast, run through the same analysis you get. Here is what came back.

Worth spacing out

Across 9 items. Some of these are better taken apart.

How this is decided

Nothing is scored or weighted. The heading is simply the most serious single thing we found, in this order:

  • Worth checking if an interaction came back at warning level.
  • Worth spacing out if an interaction came back at anything other than warning level (no level given counts as caution).
  • A few timing tweaks if no interactions, but at least one timing note.
  • Nothing flagged if no interactions and no timing notes.

Items that duplicate each other never change the heading, because overlapping supplements are a question about spending rather than safety. They are shown by color above.

Nothing flagged means we found nothing, not that a stack is safe for you. It is educational information, not medical advice.

  • CautionZinc competes with Iron absorption

    High-dose zinc (30 mg) and iron share the same intestinal transporter (DMT1), meaningfully reducing absorption of both when co-administered. Consider spacing them by at least 2 hours.

  • Move Iron away from morning cluster

    Iron absorbs best on an empty stomach and away from zinc and calcium (often present in multivitamins). Consider taking iron mid-morning or at least 2 hours apart from zinc and the multivitamin.

  • Two separate omega-3 sources overlap

    Fish oil (1,000 mg) and krill oil (500 mg) both deliver DHA/EPA; combining them is redundant unless a specific total-dose target requires it. One high-quality source is typically sufficient.

Fewer moving parts is what makes a routine stick: the more complicated a regimen gets, the heavier it feels and the more often it gets dropped. The analysis exists to take things out of your stack, not add to it.

Everything your stack needs

Stop piecing together information from a dozen websites. Stack Ritual brings it all together.

  • Free Stack Analysis

    Paste or tap in what you take and see what is redundant, mistimed, or competing for absorption. Free, no account.

  • Smart Timing

    One schedule for the whole stack, built around absorption and the conflicts above.

  • Stack Builder

    Search the library and add a supplement in a tap. Custom entries take a few seconds.

  • Inventory

    Doses remaining per bottle, a low-supply alert, and a reorder link.

  • Label Scanner

    On Pro, point your camera at the bottle and the scanner fills in name, brand, dose, and count.

  • Print for Your Doctor

    A clean one-page summary of everything you take, ready to hand over.

Also in the app: daily check-offs with streaks, mood tracking with correlation, rituals and activities, brand ratings, and community experiences.

Suggested use

How it works, in three steps.

  1. Build your ritual stack

    Add the supplements and wellness practices you want to make a habit. Stack Ritual organizes them into a daily schedule that fits your life.

  2. Connect to your existing habits

    Attach your supplements to moments you already do: morning coffee, meals, bedtime. Habit stacking makes new routines stick.

  3. Track streaks. See progress.

    Check off your stack daily, watch your streak grow, and see how your mood and energy change over time. Share a clean summary with your doctor.

Simple pricing

Start free. Upgrade when you're ready.

A supplement habit can run $50–$100+ a month. Plus costs less than a single bottle.

Stack Ritual makes sure the supplements you already pay for actually get taken, and helps you drop the ones that aren’t doing anything. It pays for itself.

Questions, answered

Everything you need to know before you start.

Is it really free?

Yes. The Free plan lets you track up to 5 supplements, build your stack, and browse the research library. No credit card, no trial clock. Upgrade only if you want unlimited supplements, reminders, and AI analysis.

Do I have to enter everything by hand?

No. Search our library of hundreds of supplements and add them in a tap. On Pro, point your camera at the bottle and the label scanner fills in the name, brand, dose, and count for you.

Will it have my supplements and brands?

Almost certainly. The library covers hundreds of supplements and rituals. If something's missing, you can add a custom entry in a few seconds.

How will I know if my stack is actually working?

Stack Ritual tracks your daily mood alongside what you actually took, then shows the correlation, so you can see what's helping and quietly drop what isn't.

Can I cancel anytime?

Yes. Plans are month-to-month (or annual if you choose) and you can cancel anytime from your account, with no calls and no hoops.

Is my health data private?

Your data is yours. It's tied to your account, never sold, and you can export a summary or delete your account whenever you want.
