Studies show that Vitamin D is a nutrient that your body requires for the formation and maintenance of healthy bones. This is due to the fact that your body can only absorb calcium, the fundamental component of bone, if vitamin D is present.
Many other biological functions in your body are also regulated by vitamin D. Its anti-inflammatory, antioxidant and neuro-protective characteristics help to maintain immunological function, muscular function and brain cell functioning.
Although vitamin D is not naturally present in many foods, it can be obtained through fortified milk, fortified cereal, and fatty fish such as salmon, mackerel, and sardines.
When direct sunlight changes a molecule in your epidermis into an active version of the vitamin (calciferol), your body produces vitamin D.
The Mayo Clinic found that a number of variables, including the time of day, season, latitude, and your skin colour, affect how much vitamin D your skin produces.
Depending on where you live and how you live, vitamin D production may decline or cease entirely during the winter months.
While sunscreen is helpful for preventing skin cancer, it can also reduce vitamin D production. Many elderly people do not get enough sunlight and have difficulty absorbing vitamin D.
If your doctor feels you aren’t getting enough vitamin D, a simple blood test can determine your vitamin D levels.
Taking a multivitamin containing vitamin D may benefit bone health. The Consumer Healthcare Products Association’s Regulation of Dietary Supplements states that the recommended daily dose of vitamin D for children under the age of 12 months is 400 international units (IU), 600 IU for persons aged 1 to 70 years and 800 IU for people over 70 years.
It is important to point out that vitamin D-3 (the natural form of vitamin D) is on the World Health Organization’s List of Essential Medicine, which is a list of pharmaceuticals required for a health system to be safe and effective.
However, new research reveals that the sunshine vitamin may also be useful in preventing a variety of other diseases. Here are three examples:
1. Depression
Because sunshine generates vitamin D and many people experience depression during the low-light winter months, it stands to reason that there is a link between vitamin D and depression.
According to Healthline’s data, a 2008 study indicated that increasing vitamin D supplements dramatically reduced depression symptoms in overweight and obese persons.
A more recent systematic review and meta-analysis published in the National Library of Medicine found that those with low vitamin D levels were more likely to suffer from depression.
2. Type 2 Diabetes
According to Healthline, a study published in the journal PLOS One in 2020 discovered that patients with vitamin D insufficiency may be at a higher risk of acquiring type 2 diabetes.
The study included healthy older persons who had no prior symptoms of diabetes or pre-diabetes. Many patients developed diabetes or pre-diabetes throughout the course of a 12-year study.
Vitamin D deficiency was revealed to be a powerful predictor of whether a person will acquire those issues among individuals who took part in the study. Finally, individuals with vitamin D levels greater than 30 nanograms per millilitre had one-third the risk of getting diabetes, while those with levels greater than 50 nanograms per millilitre had one-fifth the risk.
The study’s authors emphasised that further research is needed, but the findings are promising.
3. Dementia and Alzheimer’s
A 2014 study published in The Neurology Journal looked at the link between vitamin D insufficiency and risk factors for several types of dementia, including Alzheimer’s disease.
Researchers examined over 1,600 older persons who did not have dementia at the start of the trial.
While vitamin D was not shown to be a miracle cure for dementia, researchers did conclude that persons with moderately low vitamin D levels had a 53% higher risk of acquiring dementia than those with normal levels.
The difference was even more pronounced among people with severe vitamin D insufficiency, with this group having a 125 percent greater risk. It was also discovered that those with low vitamin D levels were 70% more likely to acquire Alzheimer’s disease.
4. Muscle strength
Higher amounts of vitamin D, said researchers at the University of Birmingham, could assist enhancing muscle strength. Participants’ active and inactive vitamin D levels, as well as their overall physical parameters, such as body fat and muscle bulk, were measured for the study.
Increased amounts of active vitamin D have been demonstrated to improve and optimise muscular strength. Because it is difficult to obtain enough vitamin D through diet alone, you should consult a healthcare practitioner before considering purchasing a vitamin D supplement.
While the data is encouraging, experts say it is critical to maintain realistic expectations. According to Healthline’s research, vitamin D increases bone density and possibly a lot of these other things as well, but we just don’t have enough data now.
Vitamin D insufficiency is still a major issue. With proven medical understanding of vitamin D’s beneficial effect on bone health, as well as promising studies into other ways it affects health. It is critical to ensure that you are receiving enough.
