Absorb: Vitamin Tracker
Pill Reminder & Interactions
Absorb is the vitamin tracker that goes beyond a pill log. Log your daily stack, get conflict alerts (iron vs calcium, zinc competition), and find synergy pairs that boost absorption — so every capsule works harder.
Most apps only count what you took. Absorb helps you take the right things, in the right pairs, at the right time — based on research-backed interaction guidance. Whether you take iron, vitamin D, magnesium, a multivitamin, or an athlete stack, Absorb keeps your routine clear, consistent, and optimized.
Key features: vitamin and supplement tracking, conflict alerts, synergy insights (iron + vitamin C, D + K2), absorption tips for timing and food, smart pill reminders, a supplement library, and light & dark mode.
Try Absorb Pro free for 3 days, then choose monthly or pay once for lifetime. Pro unlocks unlimited daily logging, full conflict & synergy alerts on Today, the complete library, and unlimited smart reminders. Subscriptions renew automatically unless canceled at least 24 hours before the period ends.
Absorb is for educational and tracking purposes only. It does not provide medical advice. Always consult a healthcare professional before changing your supplement regimen. Privacy: on-site policy at /apps/absorb/privacy/. Terms: Apple’s standard EULA.

Frequently asked questions
Is Absorb just a pill reminder?
No. It reminds you and analyzes your stack for conflicts and synergies so timing and pairing make sense — not only “did you take it?”
What is Absorb Pro?
Pro unlocks unlimited logging, full conflict and synergy alerts, the complete library, and unlimited reminders. Try free for 3 days on the monthly plan, or choose lifetime.
Does Absorb tell me which supplements to take?
No. You log what you already take. Absorb highlights interactions and timing. A clinician should guide what belongs in the stack.
Is Absorb medical advice?
No. It is for education and tracking only. Consult a healthcare professional before changing your regimen.

From the blog
-
Why you should not take iron and calcium together
A morning multivitamin, iron, and calcium together feels efficient — and often works against the iron you meant to absorb.
-
Vitamin C and iron: how timing boosts absorption
Not every pair fights. Iron + vitamin C is a classic synergy — if your stack actually puts them together on purpose.

Pill reminder vs vitamin stack tracker: what you actually need
If your only goal is “don’t forget the bottle,” any reminder works. If your stack has iron, calcium, D, and magnesium, you need more.
