Turkey Time! Sleep Time! Vitamin D and Tryptophan

December 02, 2025

Do you find yourself wide awake in the dark, counting down the hours til sunrise? 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 making the cut anymore and holiday stress is keeping you wired, your body might be sending you a message—and the solution 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 back pain levels, which is why we're excited to share some very curious research about two nutrition-based sleep supporters: tryptophan and vitamin D3.

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

Vitamin D3 for bones? That's just the beginning. Think bigger! Recent research by Wu and colleagues reveals that vitamin D3 has a crucial role in maintaining your body's stress response system—particularly your hypothalamic-pituitary-adrenal (HPA) axis. When sleep gets interrupted (hello, holiday anxiety!), this system goes crazy, 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, supporting your body's natural sleep-wake rhythm while strengthening your immune system. Think of it as a reset button for your body clock—right when the holidays are making everything off balance.

TRYPTOPHAN: NATURE'S SLEEP SIGNAL

Tryptophan: it's not just about turkey-induced naps. Wong and colleagues found that tryptophan, especially when blended with prebiotics, works through a fascinating pathway—your gut. (2) By decreasing inflammation and supporting healthy gut bacteria, tryptophan helps your body produce 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 holiday stress overwhelms everything else.

THE BOTTOM LINE

Your journey to better sleep doesn't have to requite 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.
