Xtreme NO Review

Deal Score0

Xtreme NO ReviewXtreme NO is a nitric oxide supplement used primarily by athletes and specifically by bodybuilders.  The active ingredient in Xtreme NO is the amino acid l-arginine.  This is because nitric oxide is too short lived to be able to package it in a capsule.  L-arginine converts to nitric oxide once inside the body. Xtreme NO contains three forms of l-arginine, each one converting to nitric oxide at a different pace to prolong the benefits of taking the supplement.

More Blood Flow To Muscles

Nitric oxide is well known as a vaso dilator, that is, it dilates (enlarges) the blood vessels throughout the body. Dilated blood vessels can carry more blood, therefore more oxygen and nutrients, to the muscles and organs in your body. In addition more blood flow means that more carbon dioxide is carried away from your muscles and organs. For the athlete more oxygen and nutrients to the muscles of the body means more strength and endurance resulting in better athletic performance.

What Is Nitric Oxide?

Nitric oxide is a naturally occurring gas with one molecule of nitrogen and one molecule of oxygen with the chemical symbol NO.  Note that this is not the same as nitric dioxide (NO2, a toxic pollutant) and not the same as nitrous oxide (N2O, also known as laughing gas that is used by dentists).  Nitric oxide is naturally produced by the human body to help fight off infections. Interestingly people living at high altitudes have an elevated level of nitric oxide so that they can breath normally in the thinner air.

Is Nitric Oxide Safe?

Nitric oxide supplements have been used for many years and is considered safe to use as directed for normal, healthy adults.  Check with your doctor if you have any existing health conditions or are pregnant or nursing. Those with low blood pressure should check with their doctor since one of the effects of nitric oxide is to lower blood pressure. Those under 18 should not use these supplements. Any side effects are usually short lived and can include nausea, low blood pressure, dry mouth, stomach pain.  If any side effects are severe or continue then stop using and check with your doctor.

How Do Supplements Work?

Nitric oxide itself has a very short life so supplements contain the precursor l-arginine which converts to nitric oxide once inside the body. For the athlete the benefits of taking a nitric oxide supplement is clear.  More strength and more endurance resulting in better performance.

What about Xtreme NO?

There are many nitric oxide supplements on the market so how does Xtreme NO stack up against the others?  Pretty well. Xtreme NO contains three varieties of l-arginine (l-arginine hydrochloride, l-arginine alpha-ketoglutarate and l-arginine ketolsocaproate).  These convert to nitric oxide at different times which causes a timed release effect. In addition Xtreme NO contains hypromellose which also contributes to releasing of the nitric oxide over time.

These ingredients do support the following claimed benefits of taking Xtreme No:

Taking Xtreme NO extended release supplement 30-60 minutes before your workout will

  • Boost your load capacity
  • Make that pumped look that you get while working out last all day
  • Help you build more muscle mass naturally
  • Improve mascularity
  • Reduce muscle recovery time between workouts
  • Improve stamina
  • Helps you maximize the overall effectiveness of your workout
How Do I Buy Xtreme NO?

As of this writing there are three options for buying Xtreme NO. You can buy it one month at a time or a three month supply or a trial supply. Be wary of the trial option, if you don’t cancel before the trial is over you may wind up paying too much for the product.  Check the website for detail. The three month option also has a feature where you can get Xtreme NO free for life just for the cost of shipping and handling.


I believe that Xtreme NO is a great nitric oxide product.  If you have already taken NO supplements and are just looking for a cost effective way to continue then I would go for the  3 month supply (you get 3 more months free) then continue on with the free for life option just paying shipping and handling. I do not recommend the trial option because of the cost if you don’t cancel during the trial period. I hoped this review helped.  I wish you all the best.
