Ability to log vitamins/minerals (e.g. daily vitamins caps), and supplements (e.g. creatine, omega-3, amino acids) intake.
At the moment, it is possible to add only some vitamins and minerals when creating a food. (+ Please, sync it with Apple Health !)
Also, maybe additional category of “Supplements” can be added (as: Measurements, Exercise, Water, Food ... Supplements)
