The key to a hard erection is the chemical nitric oxide which is produced naturally in the body. The problem arises if your nitric oxide levels drop - not enough nitric oxide? Sorry, no erection is possible. Here we will show you how to top it up for a rock hard erection.

Nitric oxide performs the following function:

When secreted in the blood vessels close to the penis it allows them to relax, expand and thus let an increased flow of blood in and this results in an erection.

It declines with age and is one of the commonest causes of erection problems and low libido but the good news is you can top it safely and naturally, without resorting to prescription drugs.

L arginine a non essential amino acid produced in the body has been discovered to have a key role in keeping nitric oxide levels up - when levels drop and they do as we age, nitric oxide production declines.

You can get it in supplement form and if you take between 2,500 - 3,000 mgs per day, for just a few weeks, you will get your nitric oxide levels right back up.

In a controlled test on men with erection problems, over 80% of the test group reported higher libido and better erectile function, after just 14 days of supplementation.

You can also get nitric oxide in a number of herbs.

Two of the best are the well known Chinese herb Horny Goat Weed and the lesser known but equally potent - Cnidium.

The two herbs above can be used with L Arginine and they offer other health benefits which improve libido:

Cnidium will help blood circulation, another key to strong libido and strong erections. Horny Goat Weed will top up levels of testosterone, as well as give the body an energy boost.
