What Is Vitamin K2?

Vitamin K2 is a fat-soluble nutrient that helps calcium get into the bones and teeth while keeping it out of soft tissues like arteries. Fermented foods like natto, cheese, and other animal products contain it. People often take it as a supplement to help their hearts and bones.

K2 works with vitamin D3 and calcium to improve bone density and lower artery calcification. It is typically found in combo supplements.

Can Vitamin K2 Cause Dizziness?

There is insufficient evidence to assert that vitamin K2 directly induces dizziness in healthy individuals. However, anecdotal evidence from people who take supplements often says they feel dizzy or lightheaded, especially when they start a new supplement routine or take a lot of them.

One probable reason is a sudden change in blood pressure or blood flow as K2 starts to help with vascular health. This is just a guess, and these kinds of reactions probably don't happen very often. Another option is that K2 interacts with other components, like vitamin D or calcium, or with drugs, which might make you feel dizzy.

Other Possible Causes of Dizziness When Taking Supplements

Dizziness is a common symptom that can happen for several reasons that have nothing to do with the supplement. As an example:

  • Taking vitamins without eating beforehand
  • Not getting enough water or having too many electrolytes
  • Interactions with prescription medicines, especially those that thin the blood
  • Low blood sugar

If you feel dizzy soon after taking K2, think about what else might be causing the reaction. Are you taking any other vitamins or minerals? Are you drinking enough water? Did you eat before?

How to Use K2 Safely

Many supplements provide between 90 and 200 mcg of K2, usually in the MK-7 form. Start with a low dose. If you take K2 and D3 at the same time, be sure you don't go over the safe levels for either. Always take fat-soluble vitamins with food that has healthy fats in it so that your body can use them properly.

Talk to your doctor before taking vitamin K2 if you are on blood thinners like warfarin. It can change how these drugs operate.

When to Talk to Your Doctor

If you keep getting dizzy, it gets worse, or you also have other symptoms including a fast heartbeat, fainting, or severe headaches, stop taking the supplement and talk to a doctor. Dizziness should not be overlooked, even if K2 is not the cause.

A doctor can help you figure out if the reaction is caused by the supplement or something else, including changes in blood pressure, interactions between medications, or a health problem you already have.

Conclusion

Vitamin K2 isn't usually linked to dizziness, although some people may feel this way when they first start taking it, especially if they don't take it correctly or mix it with other things. You can get the benefits of K2 without any bad side effects if you pay attention to how your body reacts and use it appropriately.
