Why Do I Taste Metal After a Workout?

Some people report tasting metal after a strenuous workout. This phenomenon is called “metal mouth” and can be caused by a few different things. Find out why you might be experiencing metal mouth and how to prevent it.


Have you ever noticed a strange metallic taste in your mouth after intense physical activity? This phenomenon is not uncommon and might cause some concern if you don’t know what it is or why it happens. In this article, we’ll explain why you may experience a metallic taste in your mouth after exercise, as well as how to manage it if it becomes a recurring issue.

The most likely explanation for the metallic taste after exercise is believed to be due to heavy sweating and dehydration. Sweat contains high amounts of electrolytes, including sodium and chlorine. These electrolytes can leave behind a salty or metallic residue on the tongue that can often be tasted for several minutes after physical activity. In addition to electrolyte buildup, dehydration can also lead to dry mouth — which is another condition that may contribute to a metallic taste.


Tasting metal after a strenuous workout is a phenomenon known as exercise-induced dysgeusia. It is a completely normal and harmless experience for many people, and there are several potential causes. Let’s explore some of these possible causes and the ways to reduce the metal taste in your mouth.


One possible cause of a metallic taste after a workout is dehydration. If you did not drink enough liquids before, during, and after your activity, it can lead to dehydration. When your body does not have enough fluids to keep up with activities and the loss of temperatures due to sweat, electrolytes like sodium and potassium are quickly depleted in the body. This can result in an electrolyte imbalance that impairs normal taste sensation and leads to the metallic taste experienced after exercise. Exercising in hot or humid conditions increases the risk of dehydration due to increased sweating. It is important to stay hydrated throughout a workout routine by drinking plenty of fluids before and during exercise, as well as afterward to replenish fluid lost from perspiration.

Electrolyte Imbalance

When hydration levels are low and electrolyte levels become altered, the influence of metals like iron, zinc and magnesium on our taste buds can increase. This is due to a decrease in saliva production, which causes the taste buds to become more sensitive to the metal ions present in these minerals. An electrolyte imbalance may be caused by an inadequate intake of electrolytes such as sodium, potassium, chloride, or magnesium. It can also happen as a result of dehydration or excessive sweating during exercise that causes a disturbance to our body’s electrolyte balance.

Therefore, it is important to maintain adequate hydration during exercise by taking regular sips of water and re-fuelling with sports drinks containing electrolytes like sodium, potassium and chloride. This will help keep your electrolyte balance in check and avoid metal tasting after exercise.

Oral Contamination

Oral contamination is a common and avoidable reason for why you may taste metal after a workout. During workouts, bacteria from the mouth and throat can enter the stomach or lungs through our inhaling and exhaling large amounts of air. This can lead to issues such as bronchitis or gastroenteritis. In addition, sweat mixed with saliva quickly wears away at protective enamel on teeth, leading to tooth sensitivity and increased exposure to oral bacteria which can bring about a metallic taste in the mouth.

To prevent this issue, it’s important to reduce the amount you ingest by practicing good oral hygiene. Brush and floss your teeth twice per day, use an alcohol-free mouthwash, and drinks lots of water often while avoiding sugary drinks. If necessary, talk to your dentist as they can provide professional advice on other methods that may help reduce oral contamination during exercise (e.g. using fluoridated toothpaste or fluoride rinses before bed). By following these tips and avoiding sugary foods before working out, you should significantly reduce the chances of tasting metal after exercise.


Exercising can be an important part of living a healthy lifestyle. However, it can also sometimes bring on undesired side effects such as tasting metal after a workout. To prevent this from happening, it is important to understand why this might be happening and what can be done to prevent it. This section will cover preventative measures that you can take to avoid tasting metal after a workout.

Hydrate before and after exercise

It is important to drink plenty of water before and after exercise. Maintaining adequate hydration helps to replenish fluid levels that can be lost through sweat during vigorous exercise, which can help to prevent a metallic taste. Furthermore, dehydration has been known to stunt performance, increase fatigue as well as cause muscle cramps and dizziness. Therefore, drinking adequate water both before and after a workout will not only help reduce the risk of tasting metal, but also help improve performance. Additionally, try drinking small amounts of fluids more often throughout the day as opposed to one large amount all at once. This will allow your body to spread out hydration throughout the day

Consume electrolyte-rich foods

After intense workouts, it is important to make sure you replenish lost electrolytes by consuming foods that are high in electrolytes. Electrolytes are minerals that are involved in numerous bodily processes, including hydration and muscle function, and when your body’s stores are depleted it can cause you to experience metallic aftertastes. Examples of electrolyte-rich foods include bananas, sports drinks, coconut water, dark leafy greens, fatty fish like salmon or mackerel, yogurt and avocados. In addition to replenishing your electrolyte stores, eating these types of food can also help ensure that you get the necessary vitamins and nutrients your body needs to recover.

Avoid eating or drinking before exercise

When you eat or drink something before exercising, the acids in your stomach can start to release certain minerals and metals into your bloodstream. Eating or drinking acidic substances before exercise can make it more likely that you will taste metal when exercising. Therefore, it’s important to avoid eating or drinking acidic foods such as coffee, soda, orange juice or carbonated beverages up to an hour before a workout. Additionally, it is a good idea to wait at least an hour after a meal before starting exercise because this also can help reduce the chances of experiencing metal taste during exercise.

If you’re feeling hungry prior to working out and sense hunger pangs coming on, then drink a cup of water instead of eating food so that it does not disrupt your workout session with metallic tastes in the mouth afterwards. Lastly, opt for snack options that are less acidic such as fruits like apples and bananas rather than processed snacks full of preservatives which could increase the risk for metal tastes appearing after exercising.


In conclusion, there can be a variety of reasons for why you might taste metal after a workout, ranging from warm up too vigorously to consuming certain supplements. It’s important to stay hydrated and take regular breaks throughout your workout to avoid feeling lightheaded or dizzy and thus reduce any metallic taste you may experience afterwards. In some cases, changes in diet or injuries may cause a metallic taste depending on their acidity levels. Be sure to talk with a healthcare professional if you start feeling more symptoms associated with the strange metallic taste and consult with a nutritionist how you can optimize your diet for the best performance results.
