ADVICE

Daily Vitamin D3 With K2 Slows Aging

  • Take vitamin D3 2000 IU daily with vitamin K2 to slow biological aging.
  • A Harvard 4-year trial found D3 reduced biological aging by ~3 years and raised hippocampal BDNF levels linked to brain health.
ADVICE

Stick To A Consistent Sleep Schedule

  • Keep a consistent sleep schedule every day to protect brain volume and cellular aging.
  • A 15-year Neurology study and Sleep Health data show consistent bed/wake times yield brains ~3 years younger and reduce social jet lag aging.
ADVICE

Use Morning Sun To Sync Your Clock

  • Get early morning sunlight or let daylight into your room to entrain circadian clocks and boost sleep quality.
  • Morning sun exposure helps sync master circadian genes that regulate neurotransmitters, hormones, digestion, and cognitive timing.
