Part 8/14:

Vitamin D supplements are derived through chemical synthesis, often using cholesterol derivatives from sheep wool. This process exemplifies how we have shifted from a solar-dependent system to engineered solutions.

Research indicates that:

• Sunlight is efficient: In as little as 10 minutes of outdoor exposure during spring and summer, the body can produce 1,000 IU of vitamin D, meeting daily requirements.

• Supplements versus natural production: While supplements can provide adequate vitamin D, they bypass the body's natural regulation mechanisms, which determine storage, activation, and utilization based on an individual's needs.
