I've Had A Persistent Metallic Taste In My Mouth For

Multiple causes discussed
Detailed Answer:
Hello and thank you for trusting us with your health related questions.
I understand your concern. Metallic taste can be a result of many causes. The most common cause are medications.
1. If you are taking over the counter supplements (such as zinc, iron, or calcium), antibiotics, anti allergy or blood pressure medication then discuss with your doctor about an alternative replacement.
2. Poor mouth hygiene may also be a cause for a taste disturbance, due to gum disease. If oral hygiene is an issue for you I recommend you see a dentist.
3. Sinus infections or allergies may also produce a metallic taste.
4. Sometimes, eating pine nuts may leave a lasting metallic taste in your mouth.
5. Too much or too little zinc in your body is also known to cause this effect. Please talk to your doctor about a zinc blood level test.
6. Ultimately, and most importantly, after having excluded the above reasons, it is important to check your liver and kidney function. Liver and kidney disease may also cause a metallic taste in the mouth.
I hope this answers your question. Let me know if I can assist you further.
Take care.
