Both men and women show reproductive and fertility benefits from vitamin D. Female participants who had a healthy vitamin D level early in pregnancy were more likely to have a baby with a healthy weight and head size in a study published in the Journal of Clinical Endocrinology & Metabolism. Similarly, men with higher vitamin D levels had a better fertility potential, particularly through better sperm motility, say researchers in a separate study, published in World Journal of Men’s Health.

Your knees are one of the most-used joints in your body and often one of the first places to experience joint pain as you get older. Research has suggested the most common causes of joint pain are osteoarthritis from joint overuse or injury, and rheumatoid arthritis – an autoimmune disease that attacks joints. Vitamin D can help protect against both types of arthritis. People who maintained healthy vitamin D levels were less likely to get rheumatoid arthritis, according to a study published in Journal of Autoimmunity. Similarly, people with low vitamin D levels reported more symptoms of osteoarthritis, like knee pain and difficulty walking, according to research by the American College of Rheumatology.
