your body changed.
your vitamins didn't.
io1 is a complete morning and evening system, built for bodies that changed after moving countries, changing diets, or just living modern life. Every nutrient paired and balanced — so you don't have to think about it.
Every supplement on the shelf was built for someone else.
Generic multivitamins make a comfortable assumption: that one pill, taken whenever, covers everyone. Your body doesn't work like that.
bottles to manage
D3, K2, magnesium, B12, zinc, iron, omega-3, probiotics — bought separately, timed by guesswork.
spent every month
Doing it properly with bioavailable forms costs more than most people realise — and most still get it wrong.
made for your body
Nutrients work in chains. Take one without its partner and your body can't use it. Almost no brand accounts for this.
One system. Day and night.
Nutrients have timing. Some energise — morning. Some restore and repair — evening with food. io1 splits them the way your body actually uses them.
Every ingredient. Every dose. Nothing hidden.
No proprietary blends. No complexes hiding tiny amounts. You see exactly what you take — in the bioavailable forms your body can actually use.
Built differently, on purpose.
Active, bioavailable forms
Methylcobalamin not cheap cyanocobalamin. L-5-MTHF not folic acid. Bisglycinate minerals not oxides.
Paired by nutrient chains
D3 with K2 and magnesium. Zinc with copper. Iron with vitamin C. Built around how nutrients actually work together.
Fully transparent dosing
No proprietary blends. Every milligram is printed. What you read is what you take.
100% vegan
Every ingredient, including the capsule, is plant-based. Built for vegetarian and vegan bodies from the ground up.
It started with my own body falling behind.
I moved countries, and within a year my vitamin levels dropped severely. I started losing my hair. Doctors shrugged. So I went deep — two years of research into how nutrients actually work.
I learned the hard way that nothing works alone. Vitamin D3 needs K2 to direct it and magnesium to activate it. Zinc needs copper to stay balanced. Iron needs vitamin C to absorb.
I built io1 around those chains. The promise is simple: we worry about the balance, so you don't have to.
Lock your price before everyone else.
io1 launches with a founding-member price that rises as we grow. Get in early, keep your rate for life.
Pre-order io1
Be first in line. No payment now — we only charge when your first box ships. Founding price of £49/mo locked for the first 100 members.
Honesty, including the fine print.
io1 is a food supplement, not a medicine. Safe for most healthy adults, but some people should speak to their doctor first.
Talk to your doctor before taking io1 if you:
- Take blood-thinning medication such as warfarin — vitamin K2 affects how these work.
- Take thyroid medication, or have a thyroid condition — ashwagandha and iodine can affect thyroid function.
- Are pregnant or breastfeeding — ashwagandha is not recommended during pregnancy.
- Have an autoimmune condition — ashwagandha may stimulate immune activity.
- Have haemochromatosis or an iron-storage disorder — applies especially to the women's formula (25 mg iron).
- Take sedatives, immunosuppressants, or have a liver condition.
Good questions, honest answers.
When does io1 ship?
io1 is in pre-order. We manufacture once enough founding members have reserved. You'll get regular updates, and we only charge when your box is ready to ship.
Why is it split into AM and PM?
Nutrients have timing. Energising nutrients like the B-complex belong in the morning; fat-soluble nutrients like D3 and CoQ10 absorb best at night with dinner.
Is it really 100% vegan?
Yes — every ingredient and the capsule itself are plant-based. No gelatin, no animal-derived D3, no fish oil.
How is this different from a normal multivitamin?
Three things: active bioavailable forms, nutrients paired by how they work together in chains, and fully transparent dosing with no hidden proprietary blends.
What if io1 isn't right for me?
Read the safety section above. And since no payment is taken until your box ships, you can step away anytime before then.
