what kind of vitamins can you overdose on?

Vitamins are highly beneficial and crucial for the body and overall health. There are basically two types of vitamins; fat-soluble vitamins and water-soluble vitamins. Water-soluble vitamins include vitamin C, vitamin B1, vitamin B2, vitamin B3, vitamin B5, vitamin B6, vitamin B7, vitamin B9, and vitamin B12. These vitamins can be excreted from the body. On the other hand, fat-soluble vitamins are vitamin A, D, E and K. Fat-soluble vitamins cause more toxicity if taken in excessive amounts because they can be stored in the tissue. These vitamins play a significant role and promote the body’s functions. 

Everybody knows that excess of everything is bad. So, taking these vitamins in a healthy amount is much needed. Now the question arises that is there any vitamin that you can overdose? And if yes, then what vitamin can you overdose on? The answer to these questions is no, the excessive amount of vitamins has adverse effects on health, be it fat-soluble or water-soluble. But it’s necessary to know that if these vitamins are taken naturally through food instead of supplements, they are less likely to cause adverse effects, even if they are taken in high amounts. Yet, consuming vitamins through supplements in concentrated dosages is risky and causes harm to the overall health. 

Vitamins less likely to cause harm

The study shows that almost every vitamin has a negative impact on health if taken excessively. But vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B5 (pantothenic acid), vitamin B7 (biotin), and vitamin B12 (cobalamin) are less likely to cause harm. One can overdose on these vitamins to some extent because there is no certain toxicity regarding these vitamins. Yet if these vitamins are taken with any formula of medication, they can react and leave negative impacts on health outcomes. These are all water-soluble vitamins. 

Another vitamin that has the low impact of toxicity while taking overdosage is vitamin K. It is a fat-soluble vitamin. It has a low potential to cause harm even if taken excessively, yet one should try to keep the amount moderate and not take any risk without caution.

overconsumption of water-soluble vitamins will result in:

  • Vitamin C

Relatively, the adverse causes of vitamin C are low, yet they can lead to gastrointestinal problems, including cramps, diarrhea, nausea, and vomiting.

  • Vitamin B3

High blood pressure occurs when the concentration of Vitamin B3 is taken in a high amount in the form of nicotinic acid. One can suffer from impaired vision, abdominal pain, or liver harm. 

  • Vitamin B6

Vitamin B6 overconsumption can lead to severe skin lesions, neurological symptoms, sensitivity to light, heartburn, or nausea.  

  • Vitamin B9

One can experience mental problems by taking folic acid excessively. The immune system can have negative impacts if high doses of vitamin B9 are consumed.


overconsumption of fat-soluble vitamins results in

  • Vitamin A

The adverse effects of vitamin A high dosage are so elevated that even death can occur. People who consume a high amount of vitamin A undergo intracranial pressure or coma. 

  • Vitamin D

People bear irregular heartbeat, appetite loss, weight loss, and organ damage by consuming excessive vitamin D.

Hence, consuming things in a limited and healthy amount is highly essential to enjoy the perks of that thing.
