In 10 randomized controlled trials with 540 patients with ED arginine supplements were found to significantly improve ED compared with placebo or no treatment.
Arginine supplements also caused significant improvements in the International Index of Erectile Function subdomain scores of overall satisfaction, intercourse satisfaction, orgasmic function, and erectile function. 
How L-arginine reliably increases women’s libido
But L-arginine has one further effect that isn’t so well-known…
It also has a dramatic impact on sexual arousal in women.
Supplementing with L-arginine can expand both sexual excitement and desire which helps you reach orgasm by amplifying both genital blood flow and smooth muscle relaxation.
L-arginine enhances sexual responsiveness by increasing the nitric oxide in your blood, which relaxes and expands your blood vessels and this lifts libido by:
- Intensifying sensation…
- Increasing blood flow…
- Stimulating the entire vaginal, and clitoral, area.
All of these physical effects of L-arginine mean that sex can quickly become more pleasurable while also increasing your desire. 
Beet juice is high in nitrates and your body turns nitrates into nitric oxide which may help prevent ED.
Research has shown that nitric oxide serves as a vasodilator to open blood vessels and helps maintain pressure in the corpus cavernosum to sustain an erection. 
Several studies have concluded that supplementing with CoQ10 may improve sperm quality, activity, and concentration by increasing antioxidant protection and may even reverse the age-related decline in egg quality and quantity in women 
Low levels of testosterone can become a serious health problem leading to lowered energy, depression, diminished libido, weight gain, muscle loss, brain fog, and more.
Women also need testosterone for their sex drive and the regulation of estrogen levels.
A daily intake of pomegranate is one of the easiest ways to improve testosterone.
Pomegranate is shown to block estrogen production and the Beckman Research Institute in California reported that pomegranate is rich in ellagitannins (ET) which convert into compounds used to stop your androgens from turning into estrogens.
This is critical to testosterone levels as too much estrogen can interfere with libido, hurt erectile health, and damage bone strength. 
In a 6-month, double-blind trial carnitine and testosterone were separately compared to placebo.
The results indicated that both carnitine and testosterone improve erectile function, and…
Carnitine has also shown promise for treating male infertility. 
Alpha Lipoic Acid
Erectile dysfunction (ED) is the inability to develop and/or maintain an erection that is sufficient for satisfactory sexual intercourse.
Patients treated with alpha-lipoic acid had their ED indicators significantly improved, and…
Alpha-lipoic acid had a beneficial effect on erectile dysfunction. 
Studies have found that inositol may be beneficial for improving the function of the ovaries and fertility in women with PCOS.
These studies have typically used doses of 2–4 grams per day, and benefits have been seen in normal-weight, overweight and obese women.
Research has also found that inositol supplements may improve menstrual cycle regularity, ovulation, and pregnancy rates in women with PCOS. 
Magnesium supplementation can help return testosterone levels to normal if the cause of the decrease is a deficiency.
One study found that taking magnesium for at least 1 month might increase testosterone in all people.
The report also added that people who exercise would see a more significant increase in testosterone levels than those who are not active. 
A 2020 meta-analysis found a direct link between vitamin D deficiency and severe ED.
Another study of young men with low vitamin D status found that those with a vitamin D deficiency had worse erectile function which suggests a link between vitamin D deficiency and ED. 
In a study with 47 women with vitamin D deficiency or insufficiency, supplementation improved sexual desire in women with vitamin D deficiency and increased the total scores for orgasm and sexual satisfaction.
These results indicate that vitamin D supplementation improves female sexual functioning and mood in women with low vitamin D status. 
Female sexual disorders are common among women, especially in their middle age, which can reduce the quality of life substantially.
In a study with 100IU (67mg) Vitamin E, 67 mg Korean ginseng, and 40 mg Siberian ginseng, it significantly improved desire and satisfaction. 
Several studies have shown that taking a selenium supplement may improve testosterone levels or aid male fertility by enhancing semen quality
A 26-week study in men with infertility noted that taking 200 mcg of selenium along with 600 mg of N-acetyl-cysteine daily increased testosterone production, sperm count, and sperm quality, compared with a placebo, plus…
Another study observed that taking 200 mcg of selenium along with 400 units of vitamin E for 100 days improved sperm motility and appearance in 53% of participants. 
Studies show a very clear relationship between zinc and testosterone levels.
In a 1996 study young men were fed a diet including very little zinc and developed a zinc deficiency.
Testosterone levels were measured and there was a significant decrease (almost 75 percent) after 20 weeks of a low-zinc diet.
The study also examined zinc supplementation in elderly men and researchers showed that with increased zinc intake, testosterone levels in the elderly population almost doubled. 
In a study on postmenopausal women, the use of zinc supplementation significantly improved sexual desire, arousal, orgasm, satisfaction, vaginal moisture, and the overall score of sexual function. 
According to a 2015 review of boron literature, taking a 6-mg dose of boron for just a week has been shown to increase free testosterone levels by nearly 25 percent.
