The risks of stacking too many
When you take several products, it is easy to get the same nutrient from more than one — a multivitamin plus separate vitamins, for example. Fat-soluble vitamins are stored in the body, so overlapping amounts can add up in a way water-soluble ones do not.
There can also be interactions between supplements, or between supplements and any medicines you take, which is not always obvious from the labels.
Simplify and keep track
A good step is to lay out everything you take and review it with a pharmacist, who can spot overlaps and flag anything worth dropping or spacing. Fewer, well-chosen supplements are easier to stay consistent with anyway.
Keeping a clear list also helps — Pillog shows what you take and when, lets you check each off from the notification, and keeps it on your phone with no account, so it's easy to see your whole routine at a glance.
