questions
Good questions, honest answers.
When does io1 ship?
io1 is in pre-order. We manufacture once enough founding members have reserved — this keeps the product fresh and lets us launch responsibly. 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. Splitting them means each one works the way your body actually uses it.
Is it really 100% vegan?
Yes — every ingredient and the capsule itself are plant-based. No gelatin, no animal-derived D3, no fish oil. The omega-3 (coming in a later version) is algal, not fish.
How is this different from a normal multivitamin?
Three things: active bioavailable forms instead of cheap ones, 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 “is io1 right for you?” section above. If anything there applies to you, please check with your doctor first. And since no payment is taken until your box ships, you can step away anytime before then.
