Frequently Asked Questions
Why is vitamin D considered a hormone?
Vitamin D is not a ‘true vitamin’, it’s actually a hormone. This is because once the ultraviolet B radiation from the sun penetrates our skin’s epidermis, our body begins the production of vitamin D, or specifically vitamin D3. Understanding this helps to explain why it’s inextricably tethered to so many biological functions.
Does vitamin D help with immune function?
There have been multiple studies that have correlated low vitamin D levels with increased infection and we now understand that vitamin D modulates both our innate and adaptive immune responses. This also ties into our understanding of the role seasons have in our fluctuating immune susceptibility. The cold weather we experience in winter doesn’t inherently cause a surge in influenza, but rather, the shorter days, decreased sunlight exposure leads to one thing – significantly less vitamin D – a biological breeding ground for illness susceptibility.
Does vitamin D help me absorb calcium?
Deficiencies in vitamin D have been linked to increased vulnerability in muscle and bone related conditions, such as increasing one’s risk of osteopenia, precipitating and exacerbating osteoporosis, and increasing muscle weakness. This is because Vitamin D plays a synergistic role in supporting the absorption of calcium in to the body.
Don’t I get enough vitamin D from the sun?
Getting consistent sunshine isn’t always easy for people living in an area with significant seasonal weather changes or for those who spend long hours working indoors; other biological variables include gender, age, body mass and race.
When's the best time to take vitamin D for performance outcomes?
Vitamin D is fat soluble, so it’s best taken with a meal that contains some fat. Given that it also boosts the absorption of calcium, these two should be taken together in the morning. Pay attention to consistent intake especially over the winter months.
