From the Research

There is currently no strong evidence suggesting that vitamin K2 supplements directly cause tinnitus. Tinnitus, characterized by ringing or buzzing sounds in the ears, is typically associated with other factors such as age-related hearing loss, ear injuries, circulatory system disorders, or medications known as ototoxic drugs (including certain antibiotics, cancer medications, and high doses of aspirin) 1, 2, 3. Vitamin K2 is generally considered safe when taken at recommended doses, which typically range from 45-320 micrograms daily depending on the specific form (MK-4 or MK-7) 4, 5. If you're experiencing tinnitus after starting a K2 supplement, it's essential to consider other potential causes or possible interactions with medications you may be taking. Some supplements can contain additives or fillers that might trigger reactions in sensitive individuals.

Key Considerations

  • The provided studies do not directly investigate the relationship between vitamin K2 supplementation and tinnitus.
  • Tinnitus is a complex condition with multiple potential causes, and its management often involves addressing underlying health issues or exploring various therapeutic options, such as cognitive behavioral therapy (CBT) 1, 2.
  • Vitamin K2 has been studied for its effects on bone health and cardiovascular function, with some evidence suggesting benefits in these areas 4, 5.

Recommendations

  • If you notice tinnitus developing after starting vitamin K2, it would be advisable to discontinue the supplement temporarily to see if symptoms improve.
  • Consult with a healthcare provider to evaluate the possible connection and explore other potential causes of your symptoms.
  • Given the lack of direct evidence linking vitamin K2 to tinnitus, it is crucial to approach this situation with a comprehensive assessment of your overall health and potential contributing factors to your symptoms.
