Vitamin D may improve your energy levels. Here’s how much you need each day

You might have heard that vitamin D can be crucial for bone health, and that taking vitamin D supplements may be in order if you’re not getting enough naturally from sunlight or from D-rich foods like eggs, oily fish, or fortified milks.

You’ve maybe even heard that vitamin D has been shown to improve cognitive function and to lower the risk of heart attack.

It may come as welcome news to learn that vitamin D could also heighten your energy levels.

That makes sense, since, according to the Cleveland Clinic, some of the top symptoms of vitamin D deficiency in adults are fatigue, muscle weakness, and low mood, which can lead to feeling down and exhausted. 

Vitamin D, also referred to as calciferol, is a fat-soluble vitamin available in foods, either naturally or through fortification, and through supplements, according to the National Institutes of Health Office of Dietary Supplements. It is also produced within the body’s cells when ultraviolet (UV) rays from sunlight hit the skin, triggering vitamin D synthesis.

No matter what the source, though, vitamin D must be activated within the body—first through the liver, which converts vitamin D to calcidiol, and then in the kidney, which forms what’s known as calcitriol.

Once activated, vitamin D promotes calcium absorption in the gut, prevents muscle cramps and spasms, and leads to healthy bone growth.

Vitamin D also plays a role in reducing inflammation, immune function, and glucose metabolism.

Does vitamin D give you energy?

A fair amount of research backs the idea that vitamin D may help put some pep in your step.
