Vitamin C is an essential nutrient that the human body cannot produce on its own. It must be obtained through dietary sources such as fruits and vegetables, with citrus fruits, strawberries, and bell peppers being particularly rich in this vitamin. Its importance cannot be overstated; Vitamin C aids in the growth and repair of tissues, helps the body absorb iron from plant-based foods, and supports the immune system in combating infections. Furthermore, as an antioxidant, it protects cells from the damaging effects of free radicals, which can lead to chronic diseases and aging.
PQQ is naturally found in foods such as kiwifruit, green tea, and fermented soybeans. The average dietary intake is relatively low, leading to interest in supplemental forms of PQQ. Studies have suggested that supplementing with PQQ may enhance cognitive function, improve sleep quality, and promote heart health. Furthermore, it has demonstrated potential in neuroprotection, suggesting it may help guard against neurodegenerative diseases.
