Over time, a woman’s libido may decrease. But this should not cause concern and alarm. Sexual desire can be stimulated by changing lifestyle, nutrition, reducing stressors and taking certain vitamins. Vitamin E According to some scientists, vitamin E can be considered the “sex vitamin”. The vitamin stimulates the production of sex hormones, increasing the desire and mood for sex in women. Vitamin E slows down the effects of aging and can increase libido. Some women use it as a lubricant to increase arousal and discharge. Applied topically, the vitamin rehydrates the superficial upper layer of the vaginal mucosa. Vitamin B6 Although not as well known as vitamin E, vitamin B6 can also improve the sex life of women. Vitamin B6 regulates and reduces the action of prolactin. This is a hormone that in high amounts can lead to a decrease in libido. Vitamin B6 also stimulates the balanced secretion of female sex hormones, estrogen and progesterone. The imbalance of the two hormones prevents the sudden change in mood and some characteristic symptoms of premenstrual syndrome. Niacin Also known as vitamin B3, niacin can be taken as a stimulant shortly before intercourse. Thirty minutes before intercourse can increase blood flow to the skin and lining of the vagina, increasing pleasure and arousal in a woman.
