From the Research
Vitamin B complex supplements are not directly associated with causing xerostomia (dry mouth) based on the most recent and highest quality study available. The study from 2021 1 investigated the effect of vitamin B complex and zinc supplements on burning mouth syndrome and found no statistically significant changes in salivary flow after treatment. This suggests that vitamin B complex supplements may not have a significant impact on saliva production or dry mouth.
Key Points to Consider
- The study from 2021 1 is the most recent and highest quality study available, and it did not find a significant association between vitamin B complex supplements and dry mouth.
- Other studies, such as the one from 2013 2, focused on the reduction of serum homocysteine levels and oral symptoms after vitamin-supplement treatments in patients with burning mouth syndrome, but did not specifically address the issue of dry mouth.
- The study from 1991 3 evaluated the vitamin B1, B2, and B6 status of patients with recurrent mouth ulcers and found that replacement therapy improved symptoms in deficient patients, but this study is older and not directly related to the question of dry mouth.
- The study from 2022 4 reviewed the role of vitamin B12 in treating recurrent aphthous stomatitis, but did not address the issue of dry mouth.
Recommendations
- If you are experiencing dry mouth after starting a vitamin B complex supplement, consult with your healthcare provider to rule out other potential causes and discuss possible strategies to manage the dryness.
- Consider reducing the dosage or taking the supplement with food to minimize potential side effects.
- Ensure adequate water intake throughout the day to help manage dry mouth symptoms.
