What are Macros?
Within the vitamin context, macros is the abbreviation for macronutrients. The prefix comes from the Greek phrase makros, which implies giant.
Merely put, macronutrients are the sorts of vitamins your physique wants every day in giant quantities (assume grams) to take care of optimum perform.
