➤ Two kinds of L-Carnitine

L-Carnitine is considered both an amino acid and a B vitamin. Like arginine, it is found in many foods, especially meat, and is also produced by the body. Studies of men with medically related erectile issues found that the combination of carnitine supplementation and Viagra was more effective than Viagra alone. Another study showed that carnitine supplementation has benefits similar to and generally superior to testosterone supplementation when treating the symptoms of ED, without problems associated with testosterone supplementation (i.e. prostate enlargement). Yet another study showed that carnitine has benefits to male fertility. In addition, among other things, helpful to both men and women, carnitine may also help lower cholesterol, may be beneficial for brain function, and may help battle fatigue and assist in weight loss or muscle building, as it helps convert fat to energy.

In addition to the most common form Acetyl-L-Carnitine HCL which has always been in NewVigor, we have now added Propionyl-L-Carnitine HCL. According to the Propionyl-L-Carnitine page on WebMD, the combination of these two carnitines for six months showed evidence of improved sexual performance, and specifically, taking the combination seemed to work about as well as testosterone supplementation. So we offer this combination as a possible alternative to supplementing with testosterone, which can have negative effects.

➤ L-Arginine

L-Arginine is an amino acid, created by the body, and found in many common foods (nuts and meats for example). Although few people are likely to have an actual arginine deficiency (which has numerous symptoms), it is possible that a greater amount of arginine may be beneficial in many ways. Among its many functions, the body uses arginine to create nitric oxide, which relaxes blood vessels and is essential for having and maintaining an erection. Viagra® functions primarily by preventing the breakdown of nitric oxide; L-Arginine helps assure that you have sufficient nitric oxide to begin with. A study of arginine showed improved sexual function in men who had low levels of nitric oxide. L-arginine is also used to address sexual dysfunction in women. It may also be beneficial in support of the immune system, the liver, and the heart and circulatory system, and may help lower blood pressure and cholesterol.

➤ L-Citrulline

L-Citrulline boosts nitric oxide in your body, one of the keys to both sexual performance and athletic performance, by relaxing arteries and improving blood flow. L-Citrulline is used by your body to create its own arginine. L-Citrulline is also found naturally in watermelon, legumes, meat, and nuts.

The short version: Why are these ingredients good for optimum sexual health?
For men, the l-citrulline and l-arginine helps your body create the nitric oxide needed to enhance the blood flow essential for strong sexual performance. (In fact, Viagra® functions primarily by preventing the breakdown of nitric oxide.) L-Carnitine has been shown to have benefits similar to those of testosterone without the drawbacks of testosterone supplementation (it has also been shown to enhance the function of Viagra), and we include both forms that have been shown to be most beneficial. LJ100 is a patented, clinically proven standardized extract of Eurycoma longifolia (also known as Tongkat Ali) from Malaysia.
