Carnitine is an endogenous, natural nutrient that is present mainly in muscles, but also in lower concentrations in vegetables, fruits and dairy products
All handling should be performed in a sterile laboratory environment using appropriate aseptic techniques
Given that isotope tracer studies show BB is clearly formed following oral l-carnitine ingestion, and similarly, isotope-labeled BB was readily converted into isotope-labeled TMA/TMAO following oral ingestion, we hypothesized that low overall plasma concentrations of gut microbiotaproduced BB in humans may be the result of microbial BB breakdown into TMA, predominantly occurring in the lower intestinal track (colon) distal to the absorption of most nutrients like l-carnitine and BB
reported that schisandrin B exhibited potent antioxidant activity by blocking the cyclooxygenase-2 (COX-2), interleukin-6 (IL-6) and interleukin-18 (IL-18) signaling pathways, thereby inhibiting collagen degradation through the suppression of matrix metalloproteinase (MMP) expression, offering protection against ultraviolet B (UVB)-induced skin damage and ROS [31]
