Vitamin Overdose: What Happens If You Intake More Than Enough
Normally, vitamins are a good thing that helps the body to function properly. Though they are typically beneficial, some people make the mistake of not realizing that vitamins can be dangerous. It is hard for a person to overdose on vitamins since they can be taken in very high amounts. However, in the rare cases where this happens, the consequences can be deadly. Here’s what you need to know about various types of mineral and vitamin overdose.
Vitamin A Overdose
Vitamin A is stored in the fat cells of the body, so it slowly builds up over time. For the average adult, taking over 770 mcg of vitamin A can cause issues. At first, it just causes rough skin, cracked nails, hair loss, and occasional nausea or dizziness. Over time, people may begin to develop blurred vision, jaundice, weakened and swollen bones, and a sensitivity to sunlight. If the overdose continues, it may lead to brain pressure, vomiting, and eventually death.
Vitamin B Overdose
There are many different B vitamins in this group, and all of them are generally responsible for regulating metabolism and building skin, hair, and nerves. When a person overdoses, the liver cannot handle the excessive amount of B vitamins so it starts to shut down. It is also possible to develop nerve toxicity from a vitamin B overdose. This causes random feelings of itchiness, numbness, pain, burning, and sensitivity in random nerves. Different types of B vitamins have different dosage levels. For example, you should never take more than 300 mg of B6 or 2,000 mg of B3.
Vitamin D Overdose
A lot of people suffer from vitamin D overdoses because they do not realize that it is in so many sources. Vitamin D is useful for building strong bones, so it is included in many fortified foods, including milk and orange juice.
