eli5: Why can’t you live off of suplements?

931 views

If you’d be able to afford all suplements for all vitamins, carbohydrates, fat, proteins,
phytochemicals and all the rest, why wouldn’t be able to survive like this? I always hear people saying you can’t but I never understood.

Supplements generally don’t include fats, proteins, and carbs, aside from very specific ones like fish oil (omega-3 fatty acids). Under that assumption, supplements of all the necessary vitamins and minerals won’t provide your body with enough calories/energy to keep running.

If you “supplement” (heh) your supplements with sufficient calories in the form of carbs, protein, and fats, then you can live off of it. But at this point, you’re just describing a balanced diet; it’s not a “supplement only” diet anymore if you’re eating regular food.
