Several animal-based studies examining effects of vitamin E on sexual function show promising results, which could mean benefits for humans as well. However, the University of Maryland Medical Center says to date there isn't evidence that any form of vitamin supplement can improve sexual performance in women and men.
Just because science doesn't strongly back using vitamin E supplements as a natural remedy for sexual dysfunction in men and women, doesn't mean this treatment hasn't been used or recommended in the past. Cleveland Clinic says vitamin E has been used in women to treat sexual arousal disorder, and the U.
National Library of Medicine says vitamin E has been used to treat sexual dysfunction. However, Mayo Clinic suggests while vitamin E supplements have historically been used to enhance sexual performance based on scientific theories or traditions, this form of treatment hasn't been thoroughly tested in humans, and effectiveness and safety aren't proven. Why Vitamin E Theoretically Works Though more research is needed to determine the exact role vitamin E might play and appropriate dosages in sexual function, there are reasons to believe it could enhance sexual dysfunction treatment.
Because vitamin E is an antioxidant and oxidative cell damage plays a role in sexual dysfunction supplementing with vitamin E especially if you're deficient in this vitamin seems to make sense.
A study in Plos One found smoking a cause of oxidative cell damage impairs erectile function. Because oxidative stress can impair sexual function, it seems likely antioxidants would be beneficial. Likewise, animal studies show promising results. Taking antioxidants, such as vitamin E, may help improve infertility, according to several human studies. One published in in the International Journal of General Medicine found vitamin E and selenium supplements may improve sperm motility and semen quality in men.
A study published in the Journal of Assisted Reproduction and Genetics shows vitamin E may improve endometrial responses in women who are infertile.
Does Vitamin E Help? Because vitamin E appears to be beneficial for sexual function in rats, it makes sense it could help people as well. Oregon State University says antioxidants show promise as a treatment for infertility in men and women, and some physicians are already using antioxidant therapy to help treat sexual dysfunction.
However, larger-scale clinical trials are needed to know if antioxidants including vitamin E are indeed effective, and which dosage is safe. How Much to Take Because effects of vitamin E on sexual dysfunction in men and women require additional research, official guidelines for vitamin E dosing for sexual function don't exist.
However, the study in the International Journal of General Medicine used doses of International Units IUs of vitamin E daily for days for treatment of male infertility. Likewise, the study in the Journal of Assisted Reproduction and Genetics used the same dosage IUs daily to treat infertility in women. MedlinePlus says the highest safe dose of vitamin E from supplements is 1, IU per day from natural vitamin E, and 1, IU daily from synthetic man-made forms of vitamin E.
At minimum, aim to get at least the recommended dietary allowance RDA , which is It's always best to check with your doctor to determine the best vitamin E dosage to meet your individualized needs. Next Steps The best recommendation is to get plenty of vitamin E-rich foods in your diet and take a multivitamin supplement containing vitamin E to prevent deficiency. Avoid taking more than 1, milligrams 1, IU of vitamin E from supplements daily as a safety precaution.
