The reason for that is because there's very little evidence for vitamins/minerals fixing actual medical issues, occasionally you'll get someone who has health issues because they're lacking something or they have too much of something but that's the exception rather than the norm. Patients don't have that much money and doctors don't have that much time. Anybody who thinks a naturopath/homeopath is more likely to solve their issue than an MD is out of their head.
A Pro should be in the Gym, or Training most Days. Whats being done, the Why and What, is done at different intensity's. With everything its getting the Balance right
