Vitamin D Update
After I reached the 8 week mark of my Carb Back-Loading experiment, I planned to draw a series of blood tests to see where things stood compared to my most recent set of labs which were drawn after doing Carb Nite for 10 weeks.
As a quick review, here are some of the basics of Vitamin D that I addressed in my prior post:
Basics of Vitamin D
- It is a hormone derived from cholesterol
- It can be made in the skin with exposure to sunlight
- It can also be ingested with food or supplementation
Effects of Vitamin D
- Maintains calcium levels in body which is important for bone health
- Regulates gene expression
- Helps immune function
- May provide anti-cancer effects
- Vitamin D levels need to be in the 50 -70 ng/mL range for thyroid hormone receptors to respond properly
- Low Vitamin D levels are seen in obesity, although I’m not entirely sure if it’s known whether obesity causes low vitamin D levels, or if it’s the other way around.
