Multivitamin Side Effects

However, if you take to many, you can experience an upset stomach, bad taste in the mouth or a headache. If you begin to have trouble breathing, facial swelling, itching or rashes, you should seek medical help immediately. Different compositions of vitamins have different side effects, so it’s incredibly important to read the labels. Often, if you experience a poor reactions, it’s because the multivitamin is low quality or you haven’t followed the correct dosage. Be sure to work with your physician to avoid the conditions mentioned in this article.

Causes Hemochromatosis.

Consuming too much iron can cause iron poisoning, which is related to liver fibrosis, also known as hemochromatosis. If left untreated, this can develop into liver cirrhosis, kidney stones and even cancer. In extremely rare circumstances, vitamin abuse can lead to organ failure.

Renal Stones

Vitamins also have their bad side, hence this article. If abused, they can be very fatal. It is not recommended to consume more than 600-800 mg per day for 14 days. Since a lot of people are in the habit of taking 1-2 tablets per ‘serving’, the chances of going over this dosage are pretty high. Taking too many vitamins can lead to renal stones, which can then turn into renal failure if left untreated. Vitamin C, if taken in excess, has been known to acidify body fluids, which leads to metabolic acidosis, a condition associated with dehydration.


Potassium is another ingredient available as a multivitamin, but if taken in large amounts, it can lead to hyperkalemia. Hyperkalemia can in turn cause a blockage in the heart, no matter your existing health status.

Although calcium is known to strengthen bones, it can have drastic effects when abused. Gallstones, or renal stones, can form within the renal system, which consists of your bladder, ureter and kidneys. Early side effects of a calcium overdose include abdominal pain, cardiac problems and constipation. Because of this, it’s incredibly important to work alongside your doctor for a vitamin supplement plan. This will prevent you from experiencing undesired side effects or more serious complications. It is better to be safe than sorry.
