About Our
Clinical Trial

We partnered with CitrusLabs, one of the leading Clinical Research Organizations in the United States focusing on evidence-based research and clinical studies for the dietary supplement industry.

The Proper Wild study is an IRB (Institutional Review Board) approved clinical research trial which investigated both qualitative and quantitative markers of health and well-being.

Overall, this trial provides evidence that Proper Wild is effective at boosting your energy, focus, mood, and productivity, while limiting negative side-effects such as stress, the jitters or crash.

Why Pair L-Theanine
With Caffeine?

Why Pair L-Theanine With Caffeine?

Our Organic Caffeine comes from Green Tea and is one of the purest available. Our L-Theanine (a naturally occurring amino acid also found in Green Tea) is produced through an enzyme assisted process that uses Green Tea leaves as one of several starting materials, which allows us to increase its purity and benefits to the user.

Multiple studies support that using Caffeine and L-Theanine together can reduce jitters and heighten concentration and cognitive alertness, while also boosting your mood.

It’s this combination of Caffeine and L-Theanine that makes Green Tea Leaves one of the world's most powerful cognitive boosters when used at the correct dosage.
