Metallic Taste and Vitamins

Can Vitamins Cause a Metallic Taste In Mouth?

Yes! Vitamins are a very common cause of metallic taste in your mouth. Multivitamins that contain metals such as copper, zinc, or chromiumcommonly leave a metallic taste in your mouth. Additionally, iron, and calcium supplements have also been linked to leaving a foul taste in your mouth. The good news is this taste should go away soon after taking the pills. If metallic taste does not go away after taking vitamin supplements, this may be an indication of an overdose or deficiency of the vitamin within your body. Below are the most common vitamins that may be causing metallic taste: 

Vitamin D:

Vitamin D supports immune function, the hardening, growth and remodeling of bones, and the absorption of magnesium. Most people obtain a sufficient amount of vitamin D through diet and exposure to sunlight. However, some of the population is at risk for a vitamin D deficiency, and can supplement this with vitamin D pills. 

If you develop metallic taste after taking vitamin D supplements, this may be an indication of an overdose of vitamin D. Other symptoms of vitamin D overdose include headaches, muscle weakness, exhaustion, irritability, and anxiety.  

Vitamin B12:

Another cause of metallic taste can be vitamin B12 deficiencyVitamin B12 is vital for the production of red blood cells in the body and keeping the nervous system in check. Along with metallic taste, other common symptoms of a vitamin B12 deficiency include headaches, tiredness, and loss of appetite.  

Iron Supplements:

Anemia is caused from an abnormally low red blood cell count in your body. If you suffer from anemia, iron supplements are one of the most common treatments for this. Iron supplements are also known to cause metallic or unpleasant taste. This is especially true for pregnant women. Prenatal vitamins often contain a high volume of iron and can also cause a metallic or unpleasant taste. Metal taste is very common during the first trimester and usually goes away as the pregnancy progresses. In addition to metallic taste, common side effects of iron supplements include upset stomach, changes in bowel habits, stained teeth, and heartburn.  


Zinc is an essential mineral involved in over 100 chemical reactions in your body. However, zinc in excess of the recommended levels may cause taste alterations, including a bad or metallic taste. Zinc lozenges (cough drops) or liquid supplements for treating the common cold are a common source of a zinc overdose. If you’re using zinc lozenges or liquid supplements, be aware that these symptoms may occur even if the product is taken as directed.
