I work out with kettle bells and am thinking of taking nitric oxide to improve my strength gains. is it safe to do so given my age?

Yes: Nitric oxide may increase endurance and possibly extend the 'pump' after a work out. The supplement is actually arginine which is an Amino Acid important to include in the diet. It is found in a well rounded diet but supplements have been found to give some athletic performance enhancement. When taken in the recommended dosage it poses little risk but the cost may not justify the use.

NITRIC OXIDE: Nitric oxide is a gas. There is a claim that l-arginine (amino acid) transforms in no. Some say improves the blood circulation and reduce the blood pressure (no produces vasodilation normally at the tissue level) but there is no prove it will replicate the normal effect under the l-arginine form. Some lists side effects including asthma and liver damage. Be careful and check with your md.
