Bacopa is a perennial plant that thrives in marshy subtropical and tropical regions around the globe. The highly regarded herb is a key ingredient in Doxiderol, a nutritional supplement that enhances cognitive function. Bacopa was chosen for its ability to protect the brain and increase acetylcholine, a biochemical messenger that enables the nervous system to relay information.

Ayurvedic practitioners first described the therapeutic properties of bacopa in 300 BC. The physicians recorded bacopa's abilities to enhance intelligence and memory. Nearly 2,500 years later, a growing body of modern research confirms the cognitive benefits of bacopa recorded in the Ayurvedic text.

In 1987, researchers in India evaluated the effects of bacopa on the intellectual function of school-aged children. During the four-week study, they administered bacopa to 40 children who were 6 to 8 years old. The scientists determined that bacopa increased perception and memory. The children were able to solve maze exercises quicker and more accurately after receiving bacopa. Many parents in India routinely use bacopa to enhance their children's intellectual development.

A 12-week study published in the August 2001 issue of Psychopharmacology investigated the effects of bacopa on cognitive function. Scientists randomly assigned the healthy volunteers, aged 18 to 65, to receive bacopa or an inactive substance. They also used a double-blind configuration for the study to conceal the identities of the products. Researchers use this design to ensure that the test results are valid because it eliminates bias by the researchers and participants. The bacopa group experienced a significant improvement in the speed at which they were able to process visual information. The participants also learned faster and stored new memories more efficiently.

In 2007, a Texas A&M College of Medicine laboratory study revealed one of the mechanisms responsible for bacopa's ability to promote brain health. According to the scientists, bacopa uses polyphenols to prevent oxidative stress and the damage that it causes to healthy brain cells. Bacopa also reduces harmful deposits of a substance known as beta-amyloid, which is the primary component of the plaque in the brains of patients with Alzheimer's disease.

A double-blind study published in the July 2008 issue of the Journal of Alternative and Complementary Medicine evaluated the effect of bacopa on elderly patients. The study confirmed that bacopa increased cognitive performance while reducing stress. According to the authors, the benefits achieved in this study confirmed the results of earlier research.

A 90-day study published in the December 2008 issue of Phytotherapy Research confirms the cognitive benefits that were previously demonstrated in other bacopa studies. Bacopa significantly improved the ability of the participants to temporarily store and use information required for completing a complex task. The double-blind study also demonstrated that bacopa reduced the time required to process visual information.

In addition to enhancing nerve signal transmission, the scientists theorize that bacopa increases cognitive function by reducing anxiety. Numerous studies indicate that anxiety interferes with the ability to perform tasks that require higher-level cognitive functions, such as learning and memorization. Stress disrupts biochemical messengers and healthy nerve signal transmission. Bacopa alleviates stress and restores a sense of calm by increasing acetylcholine levels, which reduces your heart rate and enables you to take deeper breaths.

Doxiderol is a great way to obtain the benefits of bacopa. This holistic supplement also contains other natural ingredients that promote brain health and support your ability to focus and concentrate on complex task as well as memorize information.
