Experts say the best time to take vitamin D is in the morning.  

Vitamin D has numerous potential benefits, including bone strength, mood improvement, and inflammation reduction.   

According to Jessica Cording, RD, author of The Little Book of Game-Changers, the vitamin is also beneficial in lowering the risk of certain health conditions, such as cardiovascular disease.   

While it is advised that most adults consume 600 IU of vitamin D every day, many Americans do not get enough.  

Here's why that could be: According to the National Institutes of Health (NIH), your body produces vitamin D when UV rays touch your skin.   

So, if you live somewhere not particularly sunny, or if you simply keep up your sun protection game (great!), you may come up short  

While there *are* foods that contain the sunshine vitamin (such as cod liver oil, trout, salmon, and mushrooms), the majority of them are not staples in the average American diet.  

Enter: supplements. Your decision to take any vitamin is personal, and you should discuss it with your doctor.   

However, if you decide to incorporate vitamin D into your regimen, experts say there are a few things that can affect how well your body absorbs it, such as timing and whether or not you take it with meals.  

"Since food options with vitamin D are somewhat limited, a person who rarely gets any direct sun on their body might want to consider [a supplement]," says Keri  

People who follow a vegan or vegetarian diet may also benefit from a vitamin D supplement, she notes, because many of the available dietary sources are animal-based.
