Ultimate Human Podcast - Biohacking Short on Vitamin D3

Key Points

• Focus: Anti-aging, longevity, biohacking
• Topic: Vitamin D3 (Cholecalciferol)

Introduction

• Vitamin D3 is the only vitamin synthesized by humans from sunlight and cholesterol
• Almost every cell has a receptor for Vitamin D3
• Acts more like a hormone than a vitamin
• Chronic deficiency globally

Deficiency Stats

• ~50% of global population deficient
• 85% deficiency in darker-skinned populations (African-Americans, Latinos)
• Darker skin requires more sunlight to generate Vitamin D3

Health Impacts

Immune System

• Reduces severity and duration of COVID-19
• Prevents development of autoimmune diseases
• Stimulates production of T-cells
• Enhances immune response to pathogens

Neurodegenerative Diseases

• Study (Heliyon Journal, January 2023): Impact of Vitamin D3 on diseases like Alzheimer's, Parkinson's
• Pathologies: Oxidative stress, inflammation, protein aggregation, demyelination
• Vitamin D3 may alleviate neuropathological features
• Enhances neurotransmitter (serotonin, dopamine) synthesis

Cancer & Longevity

• Lower cancer incidence in populations near the equator
• Higher life expectancy near equator potentially linked to higher Vitamin D3 levels

• Optimal blood levels: 60-80 ng/dL
• Check Vitamin D3 levels during blood work
