Why most vitamins don’t work?
The fact is many vitamin formulas aren’t properly balanced. This can hinder their absorption. (For example, too much calcium may decrease the magnesium in your system) also, some nutrients are best taken in the morning and others at high, so a multi-vitamin taken once a day is not a good idea.
Many other vitamins contain dyes and unproven ingredients (like molybdenum), yet they lack important nutrients that are depleted by stress, birth-control pills, physical exertion, smoking, and drinking.
