What this trial studies

This clinical trial investigates how Vitamin B6 supplementation influences pain thresholds and tolerance in healthy adults. Participants will receive either a high-dose Vitamin B6 or a placebo, and their responses to thermal and electrical pain stimuli will be measured. The study aims to determine the effects of a single 100mg dose and daily supplementation over a month, while also assessing related factors such as anxiety, sleep, diet, and mood. The findings could provide insights into the role of Vitamin B6 in pain management.

Who should consider this trial

Good fit: Ideal candidates are healthy adults over the age of 18 who are fluent in English.

Not a fit: Patients with chronic pain, neuropathic pain, or those on certain medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new non-pharmacological approaches for managing pain.

How similar studies have performed: While the effects of Vitamin B6 on pain have been explored, this specific approach is relatively novel and has not been extensively tested.
