State of Supplement Tracking 2026
People who track their supplements track a lot of them — and stop fast. This report is built from GoodSupp's own recent app data: what users add to their stacks, how many supplements they take per day, and how long the logging habit actually survives. Every number is original; quote any line with the sample size beside it.
The most-tracked supplements
Vitamin D3 — usually paired with K2 — is the most-tracked supplement of 2026, ahead of magnesium. The gap to the field is wide: D3 and magnesium together account for more stack adds than the next four categories combined. Creatine, long a gym-only product, now sits seventh among general users.
Key findings
5.1
The average supplement tracker logs 5.1 supplements per active day — stacks, not single pills, are the norm.

87%
87% of users who start logging supplements stop within their first week — consistency, not choice, is the supplement habit's failure point.

5×
Users who set reminder schedules outnumber consistent manual loggers roughly five to one — 53 users saved 270 schedules in the same window only 3 users logged manually for a week.
