Vitamins and minerals taken in large quantities, without the advice of a specialist, may affect the human body?

Such an example is the excess of a vitamin from B complex, which produces depletion of sources of other vitamins in the same category. In addition, random combination of vitamins can have disastrous effects on the body.

Too much vitamin A, is harmful in pregnancy.

Vitamin A is a powerful antioxidant that stimulates immunity and improves visual acuity. The recommended daily dose, recommended of specialists is between 0.6 and 0.8 mg for adults, the maximum permissible dose being 1.5 mg per day.

In large amounts, vitamin A can become toxic, causing chronic fatigue and sleepiness. In pregnant women, excess intake of vitamin A can cause premature birth or miscarriage.

High doses of vitamin C can form kidney stones.

Although it helps maintain health at the cellular level and rout colds, excess of vitamin C can prevent proper elimination of toxins through the urine, allowing for the formation of kidney stones.

Furthermore, vitamin C excess (more than 300 mg daily) may cause nosebleeds, bleeding and even scurvy, which, untreated in time, can be fatal. The recommended daily dose of vitamin C is 60-95 mg daily and this dose may be taken from a glass of fresh orange juice and a broccoli salad.

Vitamin PP reduces the blood pressure

Vitamin PP assures normal brain function, prevents pellagra (hence the designation "PP"), a disease caused by poor diet, and reduce the blood pressure. But excess of this vitamin may increase the risk of gout and diabetes. The daily intake of vitamin PP is averaging 18 mg per day.

Hypercalcemia decreases the absorption of other minerals

Excessive intake of calcium attracts a malfunction of the kidneys and reduces the absorption of other minerals such as zinc, iron and magnesium. Also, researchers at the University of California, believe that excess of calcium may contribute to the narrowing of blood vessels in the brain and causes neural damage and installation of dementia.
