A lower than normal testosterone level in a man can cause low energy levels, low sex drive, anger, irritability, sadness, nervousness and many other problems.

A doctor can check testosterone levels with a simple blood test. Saliva self-tests are also available. There are many products that claim to boost testosterone levels. These are herbal supplements and vitamin products. Some have supporting clinical trials and research and some are folk remedies. Others contain other hormones or steroids.

Two products were recently banned by the FDA, because they were found to contain anabolic steroids, which are controlled substances and cannot be sold without a prescription. Safety and quality assurance of nutritional supplements," including those that boost testosterone levels, is completely up to the manufacturer.

The FDA hears about a product first when the manufacturer sends a copy of their disclaimer statement these statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, prevent or cure any disease and second when serious problems are reported by consumers.

This leaves the consumer pretty much on his own when trying to maintain a normal testosterone level without using prescription products.

Reputable manufactures are concerned about the quality of their products, not only because it is the right thing to do, but because they want to maintain their customer base. They want customers to be happy with the products they sell.

When purchasing products to boost testosterone levels or to correct symptoms associated with a lower than normal testosterone level, select a reputable company that guarantees satisfaction and quality.

Even if the listed ingredient is one that is known to be effective, some companies try to cut cost by using chemical additives. Pure all natural herbs are expensive, so cheap products often mean cheap ingredients.

Two herbs to look for if you are interested in maintaining a normal testosterone level or if you are experiencing symptoms related to a low testosterone level are tribulus terrestris and eurycoma longifolia. These are known to boost testosterone levels naturally and are not known to cause any dangerous side effects.

Tribulus terrestris was first used in China, India and Greece to treat many conditions including headache, nausea and sexual dysfunction. More recently it has been used by athletes to enhance performance and muscularity. It is believed to boost testosterone production by stimulating the bodys production of Luteinizing Hormone which, in turn, stimulates the bodys production of testosterone.

Eurycoma longifolia, also known as Longjack and Tongkat Ali, was originally used in Asia to treat mental as well as physical fatigue. It is said to support the bodys natural production of testosterone and improve blood circulation.

Maintaining a normal testosterone level is important to maintaining an overall sense of health and well-being. Choose products to boost testosterone levels carefully.
