Several potential issues can cause or worsen erectile dysfunction. Many of these are discussed on our website. However, some are less discussed yet worthy of mention and attention; one such potential cause is a deficiency in nitric oxide. Nitric oxide, or NO, is a gas molecule that most cells in the body produce. It is an integral part of how our body functions and plays a role in activating the enzymes in blood vessels that, among other things, help make a normal erection. As we age, however, the body produces less nitric oxide (which is the case for many essential bodily functions).

Various podcasters, including Joe Rogan and Professor of Neurobiology at Stanford University Andrew Huberman, have discussed this herb in depth. They posit that taking Tongkat Ali boosts antioxidant levels in the body to fight free radicals while normalizing certain hormones like testosterone and Cortisol. Do these claims hold water? Let’s dive in.

Before we evaluate each of these claims, it is important to note that the FDA does not oversee supplements. Therefore, you must do your due diligence about which supplements to buy, as their purity and concentrations can vary. Safety should be your primary concern.
