Magnesium is important for nerve health, temperature regulation, energy production and healthy bones and teeth formation. Too much magnesium can result in diarrhoea, nausea and abdominal cramping.

Daily Intake: 350 mg/day


Potassium is important for regulating our bodily functions such as muscle contractions, homeostasis (body temperature, oxygen/carbon dioxide exchange), and digestion. Too much potassium can lead to an upset stomach.

Daily Intake: 3800 mg/day (males) and 2800 mg/day (females)


Sodium is important for regulating the amount of fluid in the body, however, too much sodium can lead to high blood pressure.
