Synthetic and natural vitamins: good or bad

Vitamins were discovered and examined not in our era and they are known long ago. Nevertheless, some of the issues associated with them, still causes misunderstandings and doubts.

Why, for example, some of these substances occur in the body by themselves, while others may be obtained only from the outside? Why without them the metabolism is disturbed, and if so - their surplus disturbs it even more? How useful are natural vitamins and harmful the synthetic ones?

I won't stop on the benefits of the natural vitamins (there are many posts on the blog about them), but here is the list of side effects of overdose of synthetic vitamins. Synthetic vitamins are dangerous, and perhaps even harmful, as they differ from the natural ones in the structure (isomer).

DN- the daily needed amount

A - can damage the bones and liver, cause hair loss, nausea, visual impairment. DN - from 0.5 to 2.5 mg.

B1 - headache, irritability, insomnia, arrhythmia.DN - 1,4-2,4 mg.

B2 - headache, irritability, insomnia, arrhythmia. DN - 2 mg.

B3 - a violation of the functions of the liver. DN - 5-10 mg, after 40 years old- diminishes.

B6 - in high doses damages the peripheral nerves. DN - 2 mg.

B9 - rash on the skin, worsens the zinc absorption. DN - 200 micrograms.

B12 - in high doses may interfere with the functions of the liver and kidneys. DN - 2-5 mg.

C - allergic manifestations, diarrhea. SP - 50-100 mg.

D - headache, irritability, fatigue, diarrhea, loss of appetite. SP - 2,5-10 mg.

E - not recommended for people with blood diseases. SP - 8-15 mg.

The wrong reception of synthetic vitamins can cause the generation of rocks in the kidneys. The reason is that everyone carries nearly 500 species of microorganisms - both useful and harmful. When the harmful microbes in the digestive system suddenly begin to multiply, they are fighting against the salt contained in urine. They neutralize the microbes, turning them into crystals. And then they simply are removed from the body with urine.
