VITAMIN D - THE SEX SUPPLEMENT?
While we often think of our sex lives and health habits as different entities, the two are undeniably intertwined.
By prioritising sleep, stress management, nutrition, hydration, exercise, and other key holistic health practices, we can support mental, physical, and crucially, sexual health.
The D Connection - The Links Between Low Libidos and Winter
It’s tough to get sufficient sunlight exposure during the dark, short days of winter. Bundling up when we do go outside in the winter sun leaves little skin exposed for cutaneous vitamin D production.

Vitamin deficiencies are a very common cause of fatigue and low libido.
Notably, healthy vitamin D levels are critical for optimal sexual function and desire. It’s also one of the most common vitamins to be deficient in.
How does vitamin D promote a healthy libido?
Vitamin D is actually a steroid hormone – therefore it’s no real surprise that it plays such a critical role in sexual health as it’s a building block of other hormones, in particular testosterone.
In a 2018 study published by the International Journal of Impotence Research, the same researchers found participants with healthy vitamin D levels were found to have better scores in erectile function, orgasmic function, and sexual desire than men with vitamin D deficiency or insufficiency.
Daily vitamin D supplementation, specifically, has been found to improve testosterone levels in men.
Compared with healthy men, subjects with vitamin D deficiency obtained lower scores for erectile function, orgasmic function, and sexual desire, while individuals with vitamin D insufficiency lower scores only for erectile function. Erectile dysfunction was more prominent in group A than in group B.
Diabetic men and smokers tended to have lower testosterone levels than men without diabetes and non-smokers.
The Takeaway
Our sex lives (and vitamin D levels) might need a little extra support through the cold winter months. To maintain healthy status and libido, supplement with high strength Vitamin D in its most bioavailable form.
