Built around your lifestyle. Refined from your data.
Why VitSync
The problem with taking everything.
A daily multivitamin is the simplest possible advice. It's also the least precise. Three things go wrong when you take one formula forever:
You don't need most of it
A typical multivitamin contains 15+ ingredients. You're probably only short on 4 or 5 of them. The rest pass straight through. You're paying for nutrients your body has no use for.
Some of it isn't harmless
Taking iron every day without a blood test can lead to overload. Fat-soluble vitamins like A, D, E, and K build up in your body over months. A multivitamin gives you all of them daily whether you need them or not. For some people, that causes real problems.
The doses are too low to help
Multivitamin doses are set at bare-minimum RDA levels so they're safe for everyone. If you actually need more vitamin D, 10µg won't move the needle. You need a therapeutic dose, and a one-a-day will never give you that.
It ignores that your needs change
Training phases, seasonal changes, and stress periods all change what your body needs. Conditions like PCOS and endometriosis mean your requirements shift throughout your cycle too. A multivitamin gives you the same thing every single day regardless of what's happening in your body.
What VitSync does instead.
Your needs shift based on how you sleep, how you eat, how you train, how stressed you are, what season it is, and what's going on in your life. Not dramatically every week. But they shift.
You sleep badly for two weeks, the data shows it, magnesium will then show up in your plan. Your outdoor hours are high in summer? Vitamin D drops off because you genuinely don't need it until October. Stress at work for a month? Ashwagandha shows up. Stress passes, it goes away.
VitSync reads those signals and gives you what your body is actually asking for, at proper doses. Nothing you don't need. Nothing that stays longer than it should. If nothing changes, your plan stays the same.

Safety checks
Checked before anything reaches your plan.
Pregnancy, medications, conditions, allergies. A safety gate runs before scoring, every week. If a supplement interacts with something you’ve told us about, we block it, flag it for a GP conversation, or suggest a safer alternative.
Your data
Your blood results never
leave your device.
They live in your phone. When the engine builds your weekly plan they're transmitted in a single API request, used in memory to shape that plan, and discarded the moment the response returns. Nothing persists on our servers. Nothing trains an AI model. We’re a wellness app, not a data business.
