Not only for vanity purposes, nitric oxide also aids in postpartum patients needing increased blood flow especially for those who had heart failure and artillery disease. The nitric oxide supplies signal in the inner lining of the heart so that the smooth muscle around it will relax thus increasing blood flow.

How to Increase Nitric Oxide Levels Naturally

Without Supplements. Although this can be done by exercising, the effects will be short-lived. That is why supplements still are most helpful for getting optimum and long-term results. Working out and taking supplements definitely go hand in hand.

You can also boost nitric oxide levels by taking in N.O. rich foods such as dark chocolate, watermelon, and walnuts but those still will not be enough and you cannot actually eat all of that every single day. You can also alter some lifestyle choices such as stopping smoking, reducing or totally avoiding high cholesterol type of foods. Consider taking supplements if you are serious about taking care of your heart and improving day to day performances.

Can N.O. Really Help with Erectile Dysfunction?

The answer to this question is YES. If you are familiar with the highly popular drug called Viagra, you may want to know that Nitric Oxide is a key ingredient of it.

You have to take into consideration though that erectile dysfunction is properly diagnosed and treated with the help of a professional physician and they may prescribe other drugs specifically targeting that ailment. Men with ED cannot produce enough blood to have it flow to their male organ so even if supplements to help to relax the muscles will be of no use.

Important Factors to Keep in Mind When Taking Nitric Oxide Supplements

When to Take the Supplement?

Nitric oxide is best as a pre-exercise regimen. It is recommended to take it about 30 minutes before strenuous activities or workouts. Nitric Oxide boosts energy and improves endurance so it is best to take it ahead to ensure high-quality exercise and to avoid easy fatigability.

Most of the supplements are recommended to take on an empty stomach for better absorption. This may cause stomach upset but can be easily reverted by drinking tons of water in between sets.

Safety Above Anything Else

Health and safety come first, looking great are just second. Nitric Oxide has benefits for the cardiovascular health however, it is still best to have your heart and blood works be checked by a specialist to ensure positive output.

If you are suffering from heart disease with circulatory problems, the levels of Nitric Oxide must be altered to a little lower than those who are taking the supplements. For beginners, I highly recommend to start slow and wait for about a month to see the results – don’t expect for results right away. Results will still vary on different body chemistry of each individual. Be reminded to cautiously stack Nitric Oxide supplements with any other supplements to avoid any untoward effects or unwanted side effects.

Consider Your Budget and Your Needs

The budget is one of the most important factors to consider in looking for the Nitric oxide supplement as it is generally cost an average buck. Most of the supplements are available for a month use and need to be taken continuously to take effect. Not only that, Nitric Oxide is just one of the many supplements that you need to take for a healthy and balanced diet.
