Effect of Alpha Hope Dietary Supplement on Health and Cognitive Performance

University of Memphis14 enrolled

Overview

The purpose of the present research study is to evaluate the claims about the supplement influencing cognitive function that may impact performance on cognitive task and related biochemical measures. The synergistic administration of Pyrroloquinoline Quinone and molecular Hydrogen (in the form of Alpha Hope) will be evaluated in adults without a diagnosis of disease (i.e., otherwise healthy adults-the population the supplement is marketed to) on certain biochemical markers, subject's self-assessed wellness, and functional measurements determined via computer tests.

Alpha Hope is a dietary supplement that contains Pyrroloquinoline Quinone and Magnesium-which has been shown to generate molecular hydrogen when mixed into water. Both Pyrroloquinoline Quinone and molecular hydrogen have been shown to exhibit antioxidant and anti-inflammatory capacities. Both Pyrroloquinoline Quinone and magnesium are widely used as dietary supplements, alone and in combination with other ingredients; however, to our knowledge, this is the first time that these two ingredients have been coupled together within one dietary supplement. Previous research has demonstrated a wide range of health benefits from Pyrroloquinoline Quinone. Of particular interest, Pyrroloquinoline Quinone has been shown to improve cognition when supplemented at daily dosages similar to that proposed in the present study. Molecular hydrogen has inherent anti-apoptosis, anti-inflammatory, and anti-oxidation properties and has therefore been studied in numerous animal studies, as well as human studies as a possible treatment for degenerative brain function. One method for generating molecular hydrogen, is using elemental magnesium, which reacts with water to generate molecular hydrogen. The purpose of the present research study is to evaluate the claims about the supplement influencing cognitive function that may impact performance on cognitive task and related biochemical measures. The synergistic administration of Pyrroloquinoline Quinone and molecular Hydrogen (in the form of Alpha Hope) will be evaluated in adults without a diagnosis of disease -(i.e., otherwise healthy adults- the population the supplement is marketed to) on certain biochemical markers, subject's self-assessed wellness, and functional measurements determined via computer tests.
