Vitamin D Is Your New Best Friend For Sex & Hormonal Health

Studies show that 93% of Americans1 are not getting enough vitamin D from the foods they eat. This is concerning because vitamin D is critical for bone health, cardiovascular function, mental well-being, healthy blood sugar levels, gut health, and more.* 

According to a 2021 Frontiers in Endocrinology scientific review2, low vitamin D status is associated with suboptimal outcomes for both mother and baby during pregnancy and certain female hormonal issues that can affect fertility.

That said, even healthy women with no known hormonal health concerns may find it more difficult to conceive if they have lower vitamin D levels. In a 2019 Human Reproduction study3, researchers found a direct relationship between vitamin D status and the likelihood of conception in women trying to conceive.

Women with optimal levels of vitamin D [i.e., 25(OH)D levels above 50 ng/mL] were 3.4 times more likely to conceive within the six-month study than women clinically deficient in vitamin D [i.e., 25(OH)D levels below 20 ng/mL].

Considering a large chunk of the population is vitamin D deficient or insufficient (29% and 41% of U.S. adults4, respectively), couples planning to conceive any time soon would be wise to look into their vitamin D levels first.

Healthy vitamin D status has been linked to enhanced erectile function, orgasmic function, and sexual desire in men6, and improved sexual desire, orgasms, and sexual satisfaction in women7.

In terms of reproductive hormone levels, vitamin D supplementation has been found to improve testosterone levels in men8 and result in healthier levels of estrogen and progesterone9 in menstruating women.*

According to a 2017 multiethnic study10 published by Maturitas, healthy vitamin D status supports healthy levels of sex-hormone-binding globulin (SHBG)—a protein that carries estrogen, progesterone, and testosterone to the tissues in need—in both men and women.

No longer menstruating? You're not out of the woods because your vitamin D levels still matter. In a 2019 systematic review11, vitamin D was shown to support vaginal pH balance and moisture (i.e., combat dryness) during menopause—and these are key factors for urogenital tract health, as well as sexual pleasure.*

If you're not sure what your vitamin D status looks like, ask your health care provider to test your levels to make sure you're in the optimal range. (Hint: Most people aren't!)

Vitamin D plays a role in many of our hormonal processes, and achieving healthy levels has been shown to have wide-reaching benefits—from hormone balance to sexual function and satisfaction.* 

Suboptimal hormone levels are the result of other health concerns. Eliminating variables like vitamin D deficiency and insufficiency can help you find the true root cause of any health challenges you may be experiencing.

mbg's vitamin D3 potency+ is a quality, high-potency source (i.e., 5,000 IU) of algal, organic vitamin D3 combined with health-supporting fats (i.e., an organic trio of avocado, olive, and flaxseed oils) in one daily gelcap. (And health experts adore it!)
