Nitric Oxide and Tachycardia

Hello , im a 17 year old teenager and weigh 174 pounds. I have been doing the p90x workout and I recently bought a Nitric Oxide supplement called Force Factor , which increases blood flow to the muscles to get a better pump and endurance. All is fine and well but i have been experiencing a high heart rate of around 100-110 beats per minute at rest. This is not normal for me and it is to my understanding that athletes have a lower resting heart beat.

I reviewed Nitric Oxide supplements and i read that they are supposed to help overall cardiovascular health , im worried that i missed somthing and i would like to know if i am causing any sort of damage to my heart.

Thank you.

It might be good to stop the Force Factor and see what happens after a few days. You're right that an athletic type person usually has a lower heart rate and BP. Can you just exercise and eat good food instead? It sounds like you want to be healthy. Too many supplements are not monitored closely enough and make empty promises. Please be careful with those.
