minerals contribute to our overall health because they your body grow, develop, and stay healthy. our bodies use minerals to us function throughout the day.tromhey us build strong bones, so we can do more things in life. with certain minerals, they can you maintain a normal heartbeat!

though, as as minerals are for us, they can also be very dangerous if one were to consume too many. if you were to take too much minerals, or even vitamins, you could experience nausea and diarrhea. all trace minerals can be very toxxic at high levels of consumption. taking too much of some minerals will result in hair loss! but this goes with almost everything in life, taking too much of something that is good, will eventually be bad for you.

my intake in minerals was normal. there really is no need to improve, i am healthy, and i am experiencing no nausea or diarrhea. i am as healthy as a bee. ☺ (sorry that i cannot you with the mineral intake)

what i have learned so far is that taking too much something can be very bad for you. taking too many minerals or vitamins, or anything healthy in general, can result in nausea and diarrhea, as well as hair loss. it would be a good idea to track what you put into your body, good or bad.
