Tracking fiber supplements (e.g. Metamucil, psyllium husk)
If you want to track fiber supplements, the best approach is to use the manual food logging feature:
Tap "Add a meal"
Switch to the Manual tab (top right)
Enter the fiber amount directly in the Fiber field
Once you've logged a supplement this way, it will appear in your recent meals so you can re-add it with a single tap in the future. The fiber amount will also be added directly to your daily fiber intake.
