Turkey Time! Sleep Time! Vitamin D and Tryptophan

December 02, 2025

Are you tossing and turning at night, watching the clock tick toward morning? With the holiday season upon us—packed schedules, family gatherings, financial pressures, and endless to-do lists—it's no wonder so many of us are losing sleep. If counting sheep isn't cutting it anymore and holiday stress is preventing you from relaxing, your body might be sending you a message—and the answer could be simpler than you think. In our chiropractic practice, we've seen firsthand that getting wellness comes from many approaches: spinal adjustments and more. Your sleep quality impacts everything from your immune system to your levels of back pain, which is why we're excited to share some very curious research about two nutrition-based sleep helpers: tryptophan and vitamin D3.

VITAMIN D3: YOUR SLEEP-WAKE CYCLE'S BEST FRIEND

Vitamin D3 for bones? That's just the start. Think again! Recent research by Wu and colleagues reveals that vitamin D3 plays a crucial role in regulating your body's stress response system—particularly your hypothalamic-pituitary-adrenal (HPA) axis. When sleep gets interrupted (think: holiday anxiety!), this system goes haywire, causing inflammation and throwing your gut health off balance. (1)  Here's the curious part: the study found that vitamin D3 supplementation helps bring back this delicate balance, helping you sleep better at night while keeping your immune system strong. It's the reset your body clock craves when holiday madness hits.

TRYPTOPHAN: NATURE'S SLEEP SIGNAL

Everyone knows tryptophan as the culprit behind Thanksgiving food comas, but this amino acid has some seriously underrated benefits. Wong and colleagues discovered that tryptophan, especially when blended with prebiotics, works via a fascinating pathway—your gut. (2) By reducing inflammation and boosting healthy gut bacteria, tryptophan helps your body produce the right sleep-promoting chemicals at the right time. Your gut literally talks to your brain about when to sleep, and tryptophan helps make sure they're speaking the same language—even when the noise of holiday stress tries to silence it.

THE BOTTOM LINE

Your journey to better sleep doesn't have to involve complicated medications. Supporting your body with vitamin D3 for hormonal balance and tryptophan for gut-brain communication can make a big difference this holiday season.
