Low Vitamin D Symptoms: 9 Signs You Might Be Deficient

Low Vitamin D is a common issue: About 40% of people don’t get enough of the sunshine vitamin and about 25% have a vitamin D deficiency that can put their bones and overall health at risk, according to research. It’s vital to watch for low vitamin D symptoms, as a lack of this micronutrient has been linked to everything from heart disease and cancer to the flu and osteoporosis, according to the Harvard T.H. Chan School of Public Health.

Keep an eye out for these low vitamin D symptoms, and see your healthcare provider and ask if you should test your vitamin D levels if you’re unsure if you’re low. Your bones, muscles, and immune system will thank you.
