A metallic taste in the mouth, also known as dysgeusia, can make food and drinks taste unpleasant and affect appetite. It may be caused by medication side effects, dental issues, nutrient deficiencies, acid reflux, infections, or other underlying health conditions. While sometimes temporary, a persistent metallic taste should be evaluated by a healthcare provider to determine the cause.
In addition to professional treatment, certain supplements may help restore normal taste perception, reduce inflammation, and support oral and nerve health. Here are two evidence-based options that may provide supportive benefits.
Zinc
Zinc is an essential mineral that plays a key role in taste perception. A deficiency can lead to altered taste sensations, including a metallic taste in the mouth. Supplementation can help restore normal taste function, especially in those with low zinc levels.
- Mechanism of action: Supports the regeneration of taste bud cells and is essential for enzymes involved in taste function.
- Dosage or usage tip: Commonly taken at 15–30 mg daily; avoid exceeding recommended amounts without medical guidance.

Vitamin B12
Vitamin B12 is vital for nerve health, including the nerves that help transmit taste signals to the brain. A deficiency can cause taste disturbances, as well as numbness or tingling in the mouth and tongue.
- Mechanism of action: Supports healthy nerve signaling and myelin production, which are essential for accurate taste perception.
- Dosage or usage tip: Commonly taken at 1,000 mcg daily, preferably as a sublingual tablet or lozenge for better absorption.
