You don't need a prescription for microencapsulated vitamin D, which is awesome because it's a real sexual performance booster.
Lockdowns taught us a lot about sex in 2020. After all, there wasn't much else to do. And in the years that followed, researchers decided to dig deeper into the topic. Dozens of post-lockdown studies taught us that sex is kind of a big deal. In a nutshell, we learned that satisfying sex leads to happier relationships, less depression, and even a longer life.
That research triggered more studies on what "good sex" actually means. For men, it's mostly about desire and performance – having a strong libido and good erection health. For women, it's about being in the mood more often and the ability to have the kind of orgasms that leave their abs sore the next day.
A flurry of sex studies followed, and a surprising number of them pointed to one commonality: good sex is strongly influenced by your vitamin D status.
Vitamin D and the horizontal tango
- Low D Leads to ED – In a mini-review, Javed et al. found that a 10 ng/mL decrease in 25(OH)D – the circulating form of vitamin D in the blood – correlates with a 12% higher erectile dysfunction risk. The mechanisms included impaired lipid metabolism, reduced testosterone, inflammation, and compromised vasodilation. Vitamin D supplementation (Buy at Amazon) enhanced erectile function and T levels.
- Boner Pills Don't Work as Well Without Vitamin D – One study investigated how vitamin D deficiency impairs erectile function by increasing superoxide radicals, which disrupt nitric oxide production and blood vessel health. Low levels not only weaken erections but also reduce the efficacy of PDE5 inhibitors. Vitamin D supplementation (at least 2,000 IU daily) improved outcomes in 60% of cases.
- Vitamin D and Sexual Motivation – This was a rat study, but interesting nonetheless. Researchers dosed up a bunch of male rats with vitamin D and found that high vitamin D rodents performed better sexually. What does that mean? Well, in rats, it means they were quick to initiate sex with females and got down to business faster. Yes, the researchers timed their "mounting and insertion" times. Rat-sex is gross to think about, but the researchers concluded that vitamin D boosts motivation via enhanced testosterone and reduced oxidative stress.
- Fertility and Vitamin D – A study on 200 infertile men found 60% had vitamin D deficiency. Reduced VDR (vitamin D receptor) expression in testes impairs steroidogenesis. Supplementation (3,000 IU daily for 12 weeks) improved fertility markers in 45% of them.
- Testosterone and Vitamin D – A meta-analysis of 10 randomized controlled trials found that vitamin D supplementation increases total testosterone by 12-18% in deficient men, with benefits for sex drive.
- Vitamin D Treats Female Sexual Dysfunction – Female Sexual Dysfunction (FSD) involves things like low desire and the inability to orgasm, and 20-40% of women experience it. In one study, when participants with FSD were treated with vitamin D, they showed an increase in testosterone and reduced oxidative stress, which resulted in improved scores on sexual satisfaction tests.
How to use this info
To avoid and possibly treat sexual performance issues, get plenty of vitamin D.
If you take a blood test to check your vitamin D status, 30 ng/mL is considered normal; however, more progressive doctors are now recommending 40-70 ng/mL. But some people appear to be "non-responders" to vitamin D supplementation and even sunlight. Several things can cause this, like being over 40 years old.
To ensure vitamin D absorption, use the microencapsulated form containing Labrasol to enhance bioavailability. D Fix High Absorption Vitamin D (Buy at Amazon) contains 5000 IU per softgel and uses this form. Used daily, one bottle lasts three months. Your bed-buddy will thank you.
