Turkey Time! Sleep Time! Vitamin D and Tryptophan

December 02, 2025

Do you lie awake through the night, eyes fixed on the clock as the hours crawl toward dawn? 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 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 affects 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. It’s time to rethink that! Recent research by Wu and colleagues reveals that vitamin D3 plays a crucial role in maintaining your body's stress response system—particularly your hypothalamic-pituitary-adrenal (HPA) axis. When sleep gets interrupted (think: holiday anxiety!), this system goes crazy, triggering inflammation and throwing your gut health off balance. (1)  Here's the interesting 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 like giving your internal clock a much-needed tune-up through the most stressful time of year!

TRYPTOPHAN: NATURE'S SLEEP SIGNAL

You've probably heard about tryptophan making you sleepy after Thanksgiving dinner, but this amino acid deserves way more credit. Wong and colleagues discovered that tryptophan, especially when blended with prebiotics, works through a fascinating pathway—your gut. (2) By decreasing inflammation and boosting 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 is shouting over it.

THE BOTTOM LINE

Sleeping better doesn't demand 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.
