Impotency or erectile dysfunction commonly occurs in adult males but happens more frequently as men get older. The malfunction often develops in the delicate blood vessels of the penis and may be a warning sign of vascular disease. Diabetes, high cholesterol hypertension and smoking are all contributing factors that damage blood vessels throughout the body. Eating healthy and getting sufficient quantities of certain vitamins may help solve the problem.
Commonly known as vitamin D, the nutrient aids in the absorption of calcium, which relaxes smooth muscle to encourage vasodilation. The vitamin is also necessary for the production of hormones, enzymes and cell growth. Researchers claim that the nutrient may improve male endurance, elevate sperm counts and reverse symptoms of erectile dysfunction. Fish, eggs, liver and fish oil are excellent sources of vitamin D. Exposing bare skin to direct sunlight for at least 10 minutes during the day is a natural means of replenishing the substance.
Erectile dysfunction often occurs due to the oxidation process of free radicals that damage and restrict blood vessels in the penis. Without adequate blood flow, the penis remains flaccid, cannot sustain or achieve a complete erection. Vitamin E is a potent antioxidant that prevents the action of free radicals. According to university research in Japan, the nutrient also has the ability to repair the damage while preventing further harm. Good sources of vitamin E include egg yolk, cheese, dark, leafy greens, meat, nuts and seeds along with vegetable oils. The vitamin is also available in a capsule supplement that may be taken twice a day.
The water soluble vitamin known as B6 plays a major role in the production of neurotransmitters, that alert the brain to cause a physical response when a man becomes aroused. B6 additionally plays a part in regulating testosterone levels and sex drive. Vitamin B6 is readily available in avocados, eggs, organ meats, diary products, vegetables and yeast.
Like Vitamin E, vitamin C is also a potent antioxidant that aids in the regulation of cholesterol while enhancing blood flow to the penis. Berries, broccoli, citrus fruits, guava, dark green vegetables, peppers and tomatoes are all good sources of vitamin C. However, some suggest taking 1,000 milligrams in tablet form to help combat impotency.
Though not a vitamin, the amino acid has antioxidant properties and is required by the body to convert fat into energy. Men having low sperm counts may have low carnitine levels. Studies also indicate that acetyl-L-carnitine and propionyl-L-carnitine supplements helped men achieve erections when sidenafil alone proved insufficient.
