Effect of a Specially Formulated Dietary Supplement With Pyrroloquinoline Quinone, γ-aminobutyric Acid, Caffeine and B-vitamins on Cognitive Function in Healthy Postmenopausal Women: a Randomized, Double-blind, Placebo-controlled Study

Various food supplements have been shown to improve cognitive function. However, there is limited data on the impact of these supplements on postmenopausal women. Millions of women experience difficulty with concentration, and memory lapses during menopause. Research shows that up to 60% of women report cognitive changes related to menopause, severely impacting their quality of life and professional performance. Women are significantly more likely to develop dementia and other cognitive dysfunction. The specially formulated Cortexium with four key ingredients aims to support cognitive function in women:

• PQQ (Pyrroloquinoline Quinone) is a redox coenzyme with high antioxidant potential and is considered to affect the brain function by increasing mitochondrial production and activation, nerve cell protection, and enhanced production of nerve growth factor.
• GABA (gamma-aminobutyric acid) is an important neurotransmitter that helps induce calm and relaxation in the brain. Its positive effects include reducing stress and anxiety, which promotes mental clarity and concentration, thus enhancing mental performance. Additionally, it can help combat fatigue by supporting restful sleep, which, in the long term, boosts brain function efficiency.
• B-VITAMINS (B1, B2, B3, B5, B6, B7, B9, B12) are essential for brain function and energy production. They support the synthesis of neurotransmitters that improve mood, memory, and concentration, and help combat stress and mental fatigue. Together, they contribute to protecting brain cells and maintaining cognitive performance.
• CAFFEINE: The stimulating and invigorating effects of caffeine on the brain and nervous system have been known for centuries. Caffeine is a mild psychostimulant with invigorating effects. It also alleviates symptoms of fatigue and enhances work capacity. Moreover, moderate amounts of caffeine are known to have a stimulating effect on the cerebrocortical fields responsible for thinking: it enhances mental activity, improves cognitive functions, and accelerates mental associations. In this way, caffeine's stimulating effect can also lead to an improved sense of well-being Our aim is test the hypothesis that Cortexium dietary supplement improves cognitive function in postmenopausal women.
