The average adult in the 21st century takes several vitamin supplements in a day. These daily pills are touted as essential requirements in any balanced diet. While it’s true that most individuals should take supplements to bridge the gap in their natural diet, it is equally important to remain vigilant about excessive consumption.
Read on to understand the dangers of vitamin toxicity, who is prone to its effects and how to take suitable precautions.

What does vitamin toxicity mean?

Similar to drug abuse, it is possible to overdose on vitamins. Experts refer to vitamin toxicity as hypervitaminosis, a condition that occurs when an excessive amount of specific vitamins is consumed, either through supplements or fortified foods. Some of the vitamins that are easily overdosed include:

  • Fat-soluble vitamins: Research indicates that vitamins such as A, D, E, and K are fat-soluble and retained in the body, while vitamin C and B-complex are water-soluble and can be easily excreted. However, since many foods today are fortified with water-soluble vitamins, it is still possible to consume more than your body needs.
  • Vitamin A: Experts say taking large amounts of Vitamin A can lead to nausea or even liver damage. You must consult your doctor before taking supplements.
  • Vitamin D: Even though most people have low vitamin D levels, overdoing the supplements can cause vitamin D toxicity. This can have the opposite effect, making one’s kidneys malfunction due to the built-up calcium in the blood.

Who is at risk of having vitamin toxicity?

The following individuals are at risk of developing vitamin toxicity:

  • Patients abuse supplements: It is safe to say that the never-ending consumption of multiple supplements without a healthcare professional’s suggestion is very dangerous. Always remember to contact a healthcare professional before changing your supplement intake.
  • Children: If a child consumes gummies or flavoured supplements, mistaking them for candies can cause a risk for toxicity.
  • People with certain medical conditions: For instance, people with liver or kidney diseases are less capable of processing or getting rid of excess vitamins.
  • Health fanatics and sportsmen: Individuals who make it their 'life goal' to attain 'perfect wellness' may find ingesting vitamins in mega doses a little tricky and even toxic.

Conclusion

Balance is crucial to preventing vitamin toxicity. The key is to stay mindful of your vitamin intake and avoid overloading your body. Adopting good eating habits, consulting your doctor regularly and exploring a variety of foods are crucial to preventing vitamin toxicity. Remember to browse health insurance plans and pick an appropriate policy to support preventative healthcare. A plan can also provide financial protection in the event of medical emergencies.
