Do you have problems sleeping? This is the vitamin you need

There are many things that can cause sleep problems, including low levels of certain vitamins. According to Bustle, vitamins and minerals are important for all bodily functions, including sleep.

"When it comes to restful sleep, certain nutrient deficiencies (low levels, but not enough to be considered a true deficiency) can play a big role," said Robin Foroutan, MS, RDN, nutritionist and spokesperson for the Academy of Nutrition and Dietetics.

You may be deficient in vitamin D, so if you can't sleep relatively easily. About 41% of Americans don't get enough vitamin D, and low levels of this vitamin can lead to sleep disorders.

Low levels of vitamin C can also make it difficult to sleep, because vitamin C can help fight the symptoms of stress. A lack of calcium may also be responsible for making it easier for you to fall asleep.

"Low calcium intake is associated with difficulty sleeping," Foroutan said. "This may be because calcium helps our brain use the amino acid tryptophan to produce melatonin, our sleep hormone."
