Vitamin D deficiency is a significant issue that can affect the vast majority of people, suggests Azeez Olayinka of Information Nigeria. Its symptoms tend to be so subtle that it goes unnoticed, while still having the potential to be dangerous. It is because of this that Vitamin D screenings can allow people to tackle the issue before there is reason for concern. Mental health, digestion, recovery from sickness, fatigue levels and even cancer and hair loss can be adversely affected by the lack of Vitamin D. Particularly individuals living in the northern hemisphere and get little sunlight should monitor their Vitamin D levels to keep healthy.
The studies that fueled the Vitamin B screening surge were based on observational research, which failed to account for crucial factors, asserts Julia Belluz of Vox. Their research found that people who used supplements were statistically in better health, failing to consider that they tend to be richer and live all-round healthier lives to begin with. Crucially, no in-depth study with randomized trials managed to find the same correlation. Doctors have jumped on the bandwagon and are encouraging their patients to get Vitamin D screenings, which are unnecessary. Until solid proof emerges, taking supplements cannot definitively be linked to better health.
