Turkey Time! Sleep Time! Vitamin D and Tryptophan

December 02, 2025

Are you staring at the ceiling each night, unable to sleep as morning approaches? As the holiday season arrives with its whirlwind of obligations—back-to-back events, family dinners, mounting expenses, and lists that never seem to end—restful sleep becomes increasingly hard to find. If counting sheep isn't making the cut anymore and holiday stress is preventing you from relaxing, your body might be sending you a message—and the solution 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 affects everything from your immune system to your levels of back pain, which is why we're excited to share some most interesting research about two nutrition-based sleep helpers: tryptophan and vitamin D3.

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

Think vitamin D3 is only for strong bones? Think again! Recent research by Wu and colleagues reveals that vitamin D3 plays a crucial role in regulating your body's stress response system—specifically 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 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 throwing 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 combined with prebiotics, works through a fascinating pathway—your gut. (2) By decreasing 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 make sure 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 a big difference this holiday season.
