First, here’s how the Nitric Boost Ultra clinical trial worked, according to the official website:
Simon told a group of men to take Nitric Boost Ultra for 60 days.
After 60 days, men reported better sexual function, greater confidence, and better overall sex at all ages.
Men found it enhanced erections and sexual performance, but many men also found it helped with energy, vitality, and overall emotional balance, among other effects.
Despite the resounding success of the trial, Simon declined to publish it in a peer-reviewed medical journal.
According to some small studies, taking spirulina supplements could help with ED. A 2024 study in Marine Drugs, for example, found that spirulina prevented damage to erections. The study took place on rats—not humans. However, researchers found that spirulina increased cavernous contractility and boosted overall erectile function even when erections were deliberately damaged.
Horny goat weed has been known as a natural libido booster for centuries. Modern research, however, has connected the plant to powerful effects in formal settings. A 2013 study, for example, found icariin – a natural molecule within the plant – had erectogenic and neurotrophic effects, helping to enhance signaling within the body linked to erections and sexual performance.
Two of the most science-backed blood flow enhancers in Nitric Boost Ultra are the amino acids L-arginine and L-citrulline. Many men take these amino acids daily for bodybuilding performance, sexual function, and ED. In a 2019 meta-analysis, researchers found that taking an arginine supplement appeared to significantly improve International Index of Erectile Function (IIEF) scores in men without adverse side effects.
Overall, Nitric Boost Ultra contains a blend of science-backed ingredients linked to erections, better sex, blood flow, and overall virility in men.
