Turkey Time! Sleep Time! Vitamin D and Tryptophan

December 02, 2025

Are you tossing and turning at night, checking the clock as it ticks toward morning? With the holiday season creeping in on 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 keeping you anxious, your body might be sending you a message—and the answer could be simpler than you imagine. 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 bigger! Recent research by Wu and colleagues reveals that vitamin D3 has 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, triggering 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, promoting healthy sleep patterns while supporting robust immune function. It's the reset your body clock wants when holiday madness hits.

TRYPTOPHAN: NATURE'S SLEEP SIGNAL

Tryptophan: it's not just about turkey-induced post-dinner rests. 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 make the right sleep-promoting chemicals at the right time. Your gut literally communicates with your brain about when to sleep, and tryptophan helps ensure they're speaking the same language—even when the noise of holiday stress tries to silence it.

THE BOTTOM LINE

Sleeping better doesn't require complicated medications. Supporting your body with vitamin D3 for hormonal balance and tryptophan for gut-brain communication can make all the difference this holiday season.
