What Is Vitamin D and Why Do You Need It in Your Body?
Many studies have shown the importance of vitamin D’s role in disease prevention as they offer a wide array of health benefits for people.
It Helps Improve Bone and Muscle Strength
Several studies highlight the benefits of consuming this vitamin to prevent the risk of fractures.
Researchers discovered that increasing supplement intake (about 500-800 IU per day) lowered hip and non-spine fractures by around 20%. Whereas, lower intakes (400 IU or less) had no effect on fracture prevention.
It Can Enhance Immune Function
This vitamin has anti-inflammatory properties that stimulate the production of immune cells. Thus, it helps to fight off a variety of diseases and disorders, including cancer, autoimmune disorders, cognitive disorders, and Parkinson’s disease.
It May Help Regulate Mood and Negative Emotions
Studies show that there is a significant link between vitamin D and mood regulation, as well as lowering the risk of depression.
According to a study, those who took supplements and experienced negative emotions saw an improvement in their symptoms. Moreover, consumption may benefit people suffering from depression or vitamin D deficiency.
Another study also tackled how low vitamin D levels could lead to the possibility of more serious fibromyalgia symptoms, anxiety, and depression.
Having sufficient amounts in the body could also keep you healthy by protecting against and possibly treating different conditions. Among these conditions are:
- High blood pressure and heart disease
- Diabetes
- Infections and immune system dysfunction
- Falls that are common in elders
