What Happens When You Overdose on Vitamin Supplements

Consumption of vitamin E supplements during pregnancy has been associated with abdominal pain and premature rupture of the amniotic sac. High doses of vitamin E supplements can prevent the clotting of blood, thus resulting in hemorrhage.

4. Vitamin B

Vitamin B comprises of vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin B5 (pantothenic acid), vitamin B6 (pyridoxine), vitamin B9 (folate), vitamin B7 (biotin) and vitamin B12 (cobalamin). Consumption of 1 to 3 grams of nicotinic acid (a form of niacin) per day can result in high blood pressure, abdominal pain, disturbed vision and even liver damage. Prolonged consumption of around 1 to 6 grams of vitamin B6 every day can cause nausea, heartburn, sensitivity to light and skin lesions. Excess consumption of folate or folic acid in the form of a supplement can affect mental function and the immune system.

5. Vitamin C

Vitamin C is usually safe but excess of it can cause gastrointestinal problems such as diarrhoea, abdominal cramps, nausea and vomiting. People consuming around 6 grams of vitamin C per day have reported migraine attacks. People with iron storage disorders such as hemochromatosis must consume vitamin C in moderation as it can cause tissue damage and fatal heart abnormalities.

6. Vitamin K

Excess vitamin K usually does not possess any side effects. However, vitamin K should be avoided by the people taking certain medications such as warfarin (blood thinner) or antibiotics as it can interfere with the action of these medicines.
