Another woman before being diagnosed with COVID-19 described her sense of taste as “bland and metallic” despite eating foods that “include many spices and strong flavors, particularly using herbs in Jamaican and Caribbean cuisines”. [2] [3]

Is Metallic Taste a Symptom of COVID-19?

Metallic taste can be a symptom of COVID-19. Metallic taste, also known as dysgeusia – a taste disorder, tends to last longer than other symptoms. Similarly, respiratory infections like the common cold can leave people with a metallic taste. Not only are people suffering from metallic taste due to COVID-19, but also from hours to weeks after the SARS-CoV-2 Vaccine. SARS-CoV-2 Vaccinations may induce transient symptoms such as muscle aches or fevers that pass in a couple of days.

Some individuals after vaccination experience a metallic taste in their mouth. One individual, John Howard NBC sports contributor, described the taste as “having nickels in your mouth”. No simple or strong taste such as mouthwash could alleviate the metal taste, which happened soon after the vaccination. While humans do not have metallic taste receptor it is the most common taste shift symptom. [4]

What is Metallic Taste?

Metallic taste is a taste disorder known as dysgeusia. Commonly, the irregular taste comes in forms of bitterness or unpleasantness. It is an abnormal or impaired sense of taste, or an unpleasant alteration of taste sensation. It is usually described as persistent metallic, sour, bitter or other unusual or bad taste in the mouth. Unpleasant tastes can occur after eating pungent foods such as onions or garlic. However, a persistent unpleasant metallic taste in the mouth is a sign of a taste disorder. Flavors of foods do not typically cause a metallic taste in the mouth; however they can worsen a metallic taste if a taste disorder is present. People may be turned away from their favorite foods or food in general due to metallic taste. This can cause serious nutrition problems due to eating less or eating saltier or sweeter foods to mask the taste.

These altered taste symptoms are interesting to discern why some people suffer from metallic taste symptoms and others are more susceptible. Metallic taste can be caused by numerous medical conditions including medication side-effect, chemotherapy, GERD, and now most notably by the coronavirus.

Why is Metallic Taste a symptom of COVID-19?

The perception of taste has been linked to the innate immune system. People who can taste bitterness well and have two copies of PAV in the gene T2R38 have a better immune response than those people who have no copies or have one copy of the gene. This is an important thing to remember when we consider people’s altered sense of taste and COVID-19[5].

Similar to other viruses, COVID-19 leads to metallic taste in the mouth due to an infection damaging the cells at the roof of your nose. However, it is different from other viruses because it can cause damage to the cells without symptoms of nasal congestion. Your change in taste is a result of the infections to supporting cells, which makes the loss of smell and taste last much longer than the common cold. [2]

How to treat loss of smell and taste?

Usually, metallic taste symptoms caused by an underlying health condition or treatment, once the condition is diagnosed and treated, the metallic taste goes away. In case with COVID-19, metallic taste might stay for a few weeks or even months. In this case, you can try some of the following remedies. Read our blog “Top 10 Metallic Taste Home Remedies”. These methods will not treat metallic taste, but can certainly help reduce symptoms of dysgeusia:

  • Olfactory Training. Treatment known as olfactory training is highly recommended for loss of taste or smell. You sniff scents for 20 seconds twice a day for at least 3 months. These scents are specific and include things such as lemons and cloves. This specific treatment is beneficial for people with infection-related loss of smell or taste. [7]

  • Lifestyle Changes. Other home remedies include simple life changes such as avoiding using metal utensils or stainless steel bottles that will worsen the metallic taste. You should cut down on foods that taste metallic or bitter to you such as coffee or red meat. Rather, choose high-protein or mild flavored foods.
  • Proper Oral Hygiene. Proper oral hygiene is helpful, such as brushing your teeth and using mouthwash.

  • Cold Food. Eating cold foods may help with the metallic taste, as well as chewing sugar-free gum and sour-tasting drops.
