In this short health‑advice video, Dr. Anne Truong states that an overwhelming 99% of men who experience erectile dysfunction (ED) also have low vitamin D3 levels. She explains that modern lifestyles limit sun exposure, which is the primary natural source of vitamin D3, and recommends at least 20 minutes of direct sunlight daily— even suggesting practical ways to get sun on an arm through a window or while driving with a moonroof open. Dr. Truong also lists dietary sources such as oysters and vegetables, and advises viewers to consider over‑the‑counter vitamin D3 supplements to correct the deficiency and potentially improve ED symptoms.

Interestingly, 99% of men that had ED have low vitamin D3. 99%, almost everyone. But the good part is you can supplement it, and you can get D3 from oysters. You can get D3 from vegetables as well. And you need the sun to get your vitamin D3. So that's why we're deficient. We're not out in the sun. You need to be out in the sun for at least 20 minutes to turn into D3. But you don't have to stay in the sun. You can drive with the moonroof open. You get the sun rays, you can drive, or you can put your arm out like this. As long as your arm is exposed to the sun, you're in your house, you can put your arm out through the window. You don't have to bring your whole entire body out, okay? But you need the sun for at least 20 minutes for your body to convert to D3. But I would suggest to buy over-the-counter vitamin D3.
