Vitamins are essential for our health, but taking too much of a certain type can lead to a variety of health risks. Excess selenium can cause fatigue and mild nerve damage, while too much calcium can increase the risk of death from cancer. Vitamin D supplements are popular, but enthusiasm for them is outpacing the evidence. High doses of vitamin D can cause muscle pain, mood disorders, abdominal pain, and kidney stones.
People over 65 may benefit from taking at least 1000 IU of vitamin D per day, in addition to taking calcium supplements and eating foods rich in vitamin D. Calcium is essential for a strong skeleton, but more than 2500 mg per day for adults ages 19 to 50 and more than 2000 mg per day for people age 51 and older can cause problems. Hair loss, gastrointestinal disorders, nausea, diarrhea, and stomach cramps are some of the other health risks associated with excessive vitamin intake. Multivitamins do little or nothing to protect against common cancers, cardiovascular disease, or death.
People with health problems can experience even more serious reactions when taking too much of a vitamin. Therefore, it is important to be aware of the recommended daily intake of each vitamin and to consult with a doctor before taking any supplements. In conclusion, vitamins are essential for our health and wellbeing, but it is important to be aware of the potential risks associated with excessive intake. Taking the recommended daily intake of each vitamin and consulting with a doctor before taking any supplements can help ensure that you are getting the right amount of vitamins without putting your health at risk.
