Don’t Focus on Vitamin D
It has been found that low vitamin D levels are significantly associated with lower bone density, muscle mass, and physical function. So, can taking vitamin D supplements make you healthier?
The answer is no. Correlation does not imply causation.
It may not be that low vitamin D is making you unhealthy — rather, it could be the habits that cause vitamin D deficiency that are harming your health.
Vitamin D is abundant in foods with quality protein, such as oily fish, eggs, and dairy products. In other words, having low vitamin D suggests that you haven’t been eating much of these foods.
Vitamin D is synthesized through outdoor activity. In other words, people who are less active outdoors tend to have lower vitamin D levels.
As such, there are complex underlying causes behind a surface-level number, and simply raising your vitamin D levels alone won’t magically solve the problem.
