Vitamin D's Unique Structure
- Vitamin D is a secosteroid hormone, meaning it has a broken ring structure unlike other steroid hormones.
- This unique structure is key to its functions like regulating calcium and supporting muscle health.
Muscle as Vitamin D Storage
- Skeletal muscle stores vitamin D, preventing its degradation.
- This explains why those with more muscle mass may need higher vitamin D doses.
Vitamin D and Energy Allocation
- High-dose vitamin D shifts surplus calories from fat storage to muscle growth.
- This shift may regulate seasonal metabolism, allocating more calories to muscle in summer and fat in winter.
