02 · The stack

Today's routine, in plain pharmacist English.

No "stack flex." No "biohack mode." Just the pills, the dose, the time, and whether you took them with food.

03 · Capabilities

Five precise capabilities.

Not twelve. Not "AI-powered." Five things, all of which earn their place.

Daily reminders

By exact time — morning or evening, with food or without. You set the cadence; we remind you.

Interaction warnings

We flag the supplements that don't mix — like calcium and iron, which compete for absorption. (Premium)

Streaks without the shame

See what you actually took, not what you wished you took. No pressure — just an honest log.

How-you-feel correlation

Notice if magnesium correlates with better sleep. No promises — just your own data, plainly shown.

06 · FAQ

Clinical answers.

Does VitLog sell supplements?
No. We don't sell anything and we're not affiliated with any brand. VitLog just logs what you take — honestly and independently.
Which supplements shouldn't I take together?
Some compete for absorption — calcium and iron should be taken about 2 hours apart, as should zinc and copper. VitLog flags these combinations for you (Premium).
Can I take vitamin D and magnesium together?
Generally yes — magnesium actually helps activate vitamin D. VitLog tracks both and reminds you when timing matters.
Does VitLog flag supplement interactions?
Yes, on Premium. VitLog flags competing minerals and suggests sensible gaps between doses.
Can I scan my supplement bottles?
You add the name and dosage manually in seconds. We focus on a reliable log rather than error-prone scanning.
Is this medical advice?
No. VitLog is a logging and reminder tool, not a medical device. Speak to your GP or pharmacist for advice.
How do I remember to take my supplements daily?
VitLog reminds you at the exact time — morning, midday or evening, with food or without. You set the rhythm.
When's the best time to take vitamin D?
Vitamin D is fat-soluble, so it's best taken with a meal. VitLog can remind you at exactly that moment.
How do I know if a supplement is actually working?
With how-you-feel correlation, you'll spot patterns over time — like magnesium and better sleep. Your data, honestly shown.
Is VitLog free?
Yes, for up to 5 supplements — and that's real, not a trial. £2.49/month unlocks unlimited supplements and the interaction warnings.
