Jujube date is a sweet fruit that has traditionally been used for medical purposes. It is typically used for weakness, fatigue, anxiety, restlessness. This herb is considered to nourish both the blood and the energy. - 12. L-Arginine
L-arginine is an amino acid that has numerous functions in the body. It helps the body get rid of ammonia (a waste product), is used to make compounds in the body such creatine, L-glutamate, and L-proline, and can be converted to glucose and glycogen if needed. L-arginine is used for erectile dysfunction. Like the drug sildenafil citrate (Viagra), L-arginine is thought to enhance the action of nitric oxide, which relaxes muscles surrounding blood vessels supplying the penis. As a result, blood vessels in the penis dilate, increasing blood flow, which helps maintain an erection. The difference in how they work is that Viagra blocks an enzyme called PDE-5 which destroys nitric oxide and L-arginine is used to make nitric oxide.
In one study, 50 men with erectile dysfunction took either 5 grams of L-arginine per day or a placebo. After six weeks, more men in the L-arginine group had an improvement compared to those taking the placebo. Unlike Viagra, L-arginine must be taken daily.- 1. Gur S, Kadowitz PJ, Trost L, Hellstrom WJ. Abstract Optimizing nitric oxide production by time dependent L-arginine administration in isolated human corpus cavernosum.

- 13. Mucuna Pruriens
Mucuna pruriens, the popular Ayurvedic herb, is also known as velvet bean or cowhage. Mucuna Pruriens contains a significant amount of naturally occurring L-dopa, an amino acid that converts into dopamine. The increased dopamine levels also optimize the production of other hormones, including testosterone, leading to increased sex drive and improved sexual performance for both men and women, beneficial in stimulating muscle growth, as well as burning fat from fat cells. Studies in rats show mucuna pruriens supplements influence dopamine content in the cortex of the brain.- 1. Manyam BV, Dhanasekaran M, Hare TA.

Independent Zenerx Reviews
"As I stated in another discussion I have tried several different ED products including V* and C*. I have tried Zenerex and was not very impressed. For me, Provigro is by far the best product I have tried. The prescription drugs were a little "over the top" for me and gave me headaches. Plus there wasn't much "control"."
