Summary
Story at-a-glance
- Research reveals vitamin D deficiency damages blood vessel health, impairing their ability to relax and significantly contributing to erectile dysfunction and broader vascular problems
- Optimal vitamin D levels (60 to 80 ng/mL) are essential for sexual function, as low levels reduce nitric oxide availability and weaken response to erectile dysfunction medications like Viagra
- Vitamin D activates protective proteins that shield blood vessels from oxidative damage, while deficiency allows harmful superoxide molecules to build up and attack vascular tissue
- Direct sunlight exposure is the best natural source of vitamin D, but supplementation with D3 is often necessary during winter months or for those with limited sun exposure
- For maximum effectiveness, vitamin D supplementation should be paired with magnesium and vitamin K2, which help activate and direct vitamin D to where it's needed most

| 0:11.5 | and erectile function until problems become hard to ignore. |

| 0:32.2 | wisdom. I'm Ethan Foster and with me is Alara Sky. Vitamin D deficiency is now widespread, and it reaches far beyond bone strength. When your |
| 0:41.5 | levels drop, everyday issues like fatigue, muscle weakness, frequent infections, or low mood, can |
| 0:47.8 | be early flags. Under the surface, low vitamin D begins to undermine your vascular system, |
| 0:53.3 | which affects every organ you rely on, |
| 0:55.8 | including sexual function. That vascular link is critical. Your arteries and small blood vessels |
| 1:01.4 | deliver the pressure and flow needed for an erection. So when they cannot relax, performance suffers. |
| 1:07.7 | Recent research shows vitamin D deficiency directly impairs that relaxation response |
| 1:12.8 | and sets the stage for erectile dysfunction and broader circulation problems. |
| 1:17.6 | A study in the British Journal of Pharmacology looked at human penile tissue from organ donors |
| 1:23.7 | and found a striking pattern. Using electrical field stimulation to mimic nerve signals, |
| 1:29.4 | tissues from donors with low vitamin D did not relax properly. Compared to tissue from donors |
| 1:34.6 | with healthier levels, the response needed for an erection was significantly weaker. |
| 1:39.5 | Researchers also ran animal experiments to see the effect inside a living body. Rats deprived of vitamin |
| 1:45.4 | D for five months showed major drops in the pressure required to sustain an erection. Mice that |
| 1:51.6 | lacked vitamin D receptors had severe dysfunction as well, confirming that adequate vitamin D |
