A recent study provided a new perspective on mitochondrial glutamine metabolism, offering mechanistic insights into metabolic adaptation during tumor hypoxia, the emergence of drug resistance, and glutaminolysis-induced metabolic reprogramming and presenting metabolic strategies to target glutamine metabolism in cancer cells

Clinical studies have shown that it has several antiaging and cardio- and neuro-protective properties, and can also alleviate osteoarticular, urologic, and menopause-related discomfort.60 The extract has also been found to have a photoprotective, modulating effect on skin pigmentation.61 Several RCTs evaluating the use of French maritime pine bark extract have shown a significant reduction in signs of facial aging, such as wrinkles and solar lentigines,62,63 and increased levels of hyaluronan synthase and type I collagen.64 Another RCT (n=76) showed increased skin elasticity and hydration and decreased skin darkening in Asians working in highly polluted areas after treatment for 12 weeks.65 No relevant adverse effects were reported
