Caffeine & Magnesium
Caffeine is widely consumed in coffee and tea because it provides an energy boost and makes you feel good. When consumed in moderation, caffeine has beneficial effects that include increased blood flow and respiration, which makes it attractive to athletes. Caffeine can have a negative impact on your body because it stimulates the kidneys and intestines and causes your body to eliminate magnesium. Long-term use of caffeine may lead to a magnesium deficiency.
Caffeine
Caffeine is a natural substance that is found in many plants, and it is most commonly found in your diet in coffee, tea and chocolate. Caffeine has a stimulating effect on the nervous system and makes you feel alert. It is considered to be a psychoactive drug because it influences your state of mind, as well as making physical changes in your body. Caffeine can boost your mood, decrease feelings of fatigue and make you more attentive, which is why it’s often the preferred drink of students. Caffeine is mildly addictive and can cause withdrawal symptoms such as headaches and irritability.

Interactions
When you consume caffeine, it temporarily acts like a diuretic, which means that you may be flushing magnesium and calcium out of your body every time you drink a caffeinated beverage. A 1994 study conducted at Washington State University showed that magnesium and calcium excretion was increased for six hours after test subjects consumed caffeine 2. Researchers caution that if you regularly consume caffeine, either in food or as a part of an over-the-counter diuretic, your body may be deficient in the minerals magnesium and calcium, which puts you at a higher risk of developing osteoporosis. Magnesium deficiency can show up as anxiety and irritability, low blood pressure and poor nail growth, and it can even lead to abnormal heartbeat.
