and what are the costs and benefits of various amounts?
Does cost just refer to price, or does it include risks?
I’d like to see information on how a person can tell if they’re deficient or oversupplied in a nutrient and what to expect if the problem is being remedied. For example, a person might have a blood test which shows a deficiency, but if they trouble absorbing the nutrient, just taking more may not help and (faint memory) they might even be deficient while having what seems to be enough in their blood.
