Key takeaways
- Erections depend on blood vessels relaxing, which nitric oxide controls.
- Age, smoking, inactivity and poor diet all reduce nitric oxide.
- Leafy greens, beets, exercise and key amino acids help support it.
What nitric oxide does
Nitric oxide is a gas your blood vessel lining makes naturally. It tells the smooth muscle in vessel walls to relax, so vessels widen and blood flows more freely. An erection is, at its core, a blood-flow event, so healthy nitric oxide signaling matters.
Why it drops with age
Nitric oxide production tends to fall as men get older. Smoking, high blood pressure, high blood sugar, inactivity and a diet low in vegetables make it worse. This is one reason erection quality can decline gradually after 40. If changes are sudden, see a doctor; MedlinePlus explains the common medical causes.
Foods that support nitric oxide
Nitrate-rich vegetables such as spinach, arugula, beets and celery help the body make nitric oxide. Watermelon provides L-Citrulline. Dark chocolate, pomegranate and garlic are also popular choices for circulation.
Habits that help
Regular exercise is one of the strongest natural nitric oxide boosters, as is not smoking and keeping a healthy weight. Sleep and stress matter too; see how stress affects libido.
Where Alpha Erec fits
Alpha Erec includes L-Arginine and L-Citrulline, the two amino acids behind nitric oxide, plus Panax Ginseng. Learn how they differ in L-Arginine vs L-Citrulline, or see how Alpha Erec works.
Frequently asked questions
Does nitric oxide help erections?
Yes. Nitric oxide relaxes blood vessels so more blood can flow into erectile tissue, which is central to getting and keeping an erection.
What is the fastest natural way to raise nitric oxide?
Exercise and nitrate-rich foods such as beets and leafy greens are among the quickest natural ways to support nitric oxide production.
