How Does Red Rex Work?
The supplement first stimulates the release of additional nitric oxide in the body, which claims to improve circulation. The icariin in Epimedium is a potent substance which may help with this release, as is L-Arginine.
A study on rats in the Asian Journal of Andrology found that icariin improved erectile function.
The improved blood flow to the manhood helps to strengthen erections. This product also claims to help dilate the blood vessels, so that more blood is able to flow through.
Red Rex Ingredients
These are the primary active ingredients in this product:
L-Arginine – This is an amino acid which can initiate extra nitric oxide in the body, leading to harder erections. A meta-analysis of research in the Journal of Sexual Medicine found this substance to be very effective at treating erectile dysfunction, orgasmic function, and overall sexual satisfaction.
Cnidium Monnieri – This is a flowering plant also called Monnier’s Snowparsley. In Asia people use it frequently as an herbal medicine to treat a number of conditions. According to an article in Translational Andrology and Urology it dilates the blood vessels, making it a useful treatment for erectile dysfunction.
Epimedium Brevicornum – This is a plant which is also called horny goat weed. It contains a strong substance called icariin. It’s considered to be a potent aphrodisiac, and a possible treatment for impotence. A study in mice in Andrologia found that this substance was effective in enhancing male sexual function.
Is Red Rex Safe?
The ingredients in this product are quite safe, except for the warnings to asthma sufferers and people having surgery. For the most part, they only lead to mild side effects.
