Scientific Evidence for Onnit: Clinical Studies

Most nutritional supplement companies don’t invest in clinical trials. They’re too expensive. Onnit, however, has invested in multiple clinical trials. The company has run clinical trials on Shroom Tech Sport, Total Strength + Performance, Alpha Brain, and other formulas. We’ll summarize some of that scientific evidence below.

In 2017, Onnit published the results of its flagship clinical trial on Shroom Tech Sport. Researchers at Florida State University performed that trial. Researchers gave Shroom Tech Sport to participants in a double-blind, placebo-controlled setting, then measured the results over 12 weeks. After 12 weeks of taking Shroom Tech Sport, participants increased bench press reps by 12%, increased bench press and back squat reps by 7%, and improved cardio performance by 8.8% more than the placebo.

Similarly, this 2015 study analyzed the effects of Total Strength + Performance in resistance-trained men over four weeks. Researchers gave 27 college-aged powerlifters Total Strength + Performance or a placebo, then analyzed the results. After taking Total Strength + Performance for four weeks, researchers found the formula significantly increased one rep max for a squat, bench, and deadlift combined total weight compared to the placebo. Participants also added an average of 6kg (13.7lbs) to their 1RM bench press compared to the placebo. Plus, researchers found the formula was well-tolerated and did not alter hormone profiles.

Onnit has also conducted clinical trials on Alpha Brain. In this 2016 study, researchers gave Alpha Brain to participants in a double-blind, placebo-controlled setting. A group of 63 participants between ages 18 and 35 took Alpha Brain or a placebo for six weeks, then completed neuropsychological tests to analyze the effects. After six weeks of taking Alpha Brain, participants significantly improved delayed verbal recall tasks and executive functioning compared to a placebo. Because of these effects, researchers concluded that Alpha Brain significantly improved recent verbal memory compared to a placebo. However, they cautioned that this was the first clinical trial on Alpha Brain, and further study was needed.

Other studies have taken place on Onnit supplements without Onnit’s support. In this 2018 study, for example, researchers analyzed the effects of Alpha Brain in active duty US soldiers. Forty-three soldiers participating in a professional military course took Alpha Brain or a placebo for 30 days, taking three pills per day. Then, participants were asked to complete a marksmanship test. Researchers found that Alpha Brain “did not have any statistically significant effects on marksmanship performance in this study.” There was no significant difference between the Alpha Brain group and the placebo for accuracy, speed, and other metrics.

Overall, Onnit is one of the few nutritional supplement companies with clinical research supporting its formulas. You can view more information about Onnit’s clinical trials.
