Vitamin D is crucial for bone health, immune function, and even nervous system signaling, but may not be adequately synthesized from sunlight alone, despite the longer, sun-filled summer days.

Regular consumption of green tea is linked to longevity, brain health, increased energy expenditure, immune function support, and improved biomarkers of heart health.

Caloric restriction (CR) activates a core gene activity program that promotes immune function, reduces inflammation, and reveals a potential mechanism to mimic the beneficial effects of CR.

Eight days of intense meditative practice enhances immune function without activating inflammatory signals, showing that meditation may be a new way to support both immune and brain health.
