Vitamin D helps to regulate the amount of calcium and phosphate in the body, according to the NHS.
The vitamin – sometimes known as the sunshine vitamin – helps to keep teeth and bones strong and healthy.
Without enough vitamin D, you’re more at risk of developing bone deformities, including rickets and osteomalacia.
But, you could lower your risk of vitamin D deficiency by taking supplements during the winter months.
These are the top benefits of taking vitamin D supplements, including weight loss.
“Your body produces vitamin D naturally when it’s directly exposed to sunlight,” said medical website Healthline.
“You can also get it through certain foods and supplements to ensure adequate levels of the vitamin in your blood.
“Getting a sufficient amount of vitamin D is important for normal growth and development of bones and teeth, as well as improved resistance against certain diseases.
“If your body doesn’t get enough vitamin D, you’re at risk of developing bone abnormalities such as soft bones or fragile bones.
“Consider adding vitamin D supplements to your diet if you’re trying to lose weight or prevent heart disease.”
Adding more vitamin D to your diet could help you to lose weight, a study has claimed.
Taking vitamin D supplements helped people to lose weight over a 15-week period.
Combined with calcium supplements, they worked to suppress appetite, scientists claimed.
Vitamin D may also help to prevent mental health conditions, including depression, studies have reported.
Patients with depression reported their symptoms improving after taking vitamin D supplements for one year, a Norwegian study claimed.
Vitamin D may also help to prevent some diseases and infections.
You could lower your risk of heart disease, flu and even multiple sclerosis by adding more vitamin D to your diet, said Healthline.
The Department of Health recommends that all UK adults consider taking vitamin D supplements during the autumn and winter months, as daylight hours are reduced.
Those most at risk of a deficiency in the sunshine vitamin include people that live in care homes, people that aren’t often outdoors, and people that usually wear clothes that cover up most of their skin.
But, never take too much vitamin D over short periods of time. Taking more than 100mg everyday could be harmful, the NHS warns.
