I am experiencing heart palpitations. Is this normal?

Vitamin K2, when used at suggested dosage, does not have known side effects, as it is an essential nutrient for the human body. However, if you are deficient in Calcium, Magnesium, potassium, and CoQ10, you may experience heart palpitations. If you experience palpitations, discontinue use immediately and consult with your doctor and consider addressing the deficiencies noted above.
