MegaDose is for people who take vitamin C seriously — not once a day, but 6, 8, even 10 times a day in split doses.
WHY SPLIT DOSING?
Your body can only absorb a limited amount of vitamin C at once. Spreading doses throughout the day means more gets used. MegaDose is built around that protocol — not around casual supplement reminders.
ONE TAP TO LOG
Tap the pulse button to log your default dose. Long-press for a larger loading dose when ramping up. That's it. Fast, no friction.

DISCLAIMER
MegaDose is a personal tracking tool. It does not provide medical advice, diagnosis, or treatment. High-dose vitamin C can increase urinary oxalates and cause GI distress. Always consult a healthcare professional before changing your supplementation — especially if you have kidney disease, a history of kidney stones, or are pregnant or nursing. You are responsible for your own dosing decisions.
