what is side effect of overdose of multivitamins?

Answer 1

The effects will be the consequences of the individual components. A single overdose is unlikely to have much effect. However, a chronic overdose, especially of the fat soluble vitamins A, D, and E, may lead to negative health consequences.

For vitamin A, effects may be nausea loss of appetite, headache, peeling skin, hair loss, tiredness, menstrual irregularity, enlarged liver, enlarged spleen.

For vitamin D, these include bone pain; calcium deposits (hard lumps) in tissues outside of the bone; cloudy urine; drowsiness; increased sensitivity of eyes to light or irritation of eyes; itching of skin ; loss of appetite; loss of sex drive; mood or mental changes; muscle pain; nausea or vomiting; protein in the urine; redness or discharge of the eye, eyelid, or lining of the eyelid; runny nose; weight loss.

For vitamin E, side effects at large doses may include blurred vision; diarrhea; dizziness; headache; nausea or stomach cramps; unusual tiredness or weakness.

Some of the B-vitamins also have side effects at large doses. You can look them up for yourself here: http://www.nlm.nih.gov/medlineplus/druginfo/drug_Ua.html

Answer 2

It depends on the kind of vitamin you take. If it is composed of the water soluble vitamins like the Vitamin C and B complex, there is no problem if it is only about 3 or 4 times the normal dose as these vitamins when they are in excess of what the body needs at that moment are just eliminated by the body in the kidney passing out with the urine. But the fat soluble vitamins like Vitamin A,D.E and K, overdosage of this is not good because these are just stored in the liver and are not eliminated not until they are used by the body. There are many side effects because for every kind of vitamin, each one has their own particular symptoms that would show if you continue overdosing yourself.Don't worry it will not kill you unless you have been taking too much for a long time. Just stop for awhile then you can take the normal dose again.

Answer 3

Vitamins are classified as either water soluble, meaning that they dissolve easily in water, or fat soluble, and are absorbed through the intestinal tract with the help of lipids. Each vitamin is typically used in multiple reactions and therefore, most have multiple functions. In humans there are thirteen vitamins, divided into two groups; four fat soluble vitamins (A, D, E and K), and nine water soluble vitamins (eight B vitamins and vitamin C).

The water soluble vitamins are no problem, however the fat soluble are another matter. The fat soluble vitamins, namely vitamins A, D, E and K, are mostly found in fatty foods and fish liver oils are particularly rich in vitamins A and D. This means that a certain amount of fat is needed in the diet to help the body absorb these vitamins. Vitamins A and D are also found in human liver and if the diet contains more vitamin A or D than is immediately required the surplus is stored in the liver. Enough of these vitamins are stored in the liver of a well nourished person to satisfy the body's needs for several months if they are absent from the diet. If the diet contains too much vitamin A or D, however, the surplus will accumulate in the liver and may be harmful. The strangest (to me) condition from excessive vitamin intake (A, specifically) is known as pseudotumor cerebri.

This being said, you can go to Medline and look up specific vitamins, but unless it's a chronic ingestion, even the fat soluable vitamins will have little effect in a one time dosage.
