Osteoblasts have a high rate of energy consumption during bone formation and bone protein synthesis. Therefore, it is likely that decreased energy production that accompanies aging, could contribute to reduced osteoblast activity, a critical feature of senile osteoporosis, and that this reduction might be counteracted by favoring energy availability. Cells of the osteoblastic lineage generate 40–80% of the requested energy through fatty acid degradation, thus the modulati...

Betaine (BET) is a component of many food. It is an essential osmolyte and a source of methyl groups. BET consumed from food sources and through dietary supplements presents similar bioavailability. BET exerts an antioxidant activity and decreases inflammation states. Dietary supplement with BET are used in many inflammation-connected pathologies, although its mechanism of action is not fully understood. Recent studies have shown that BET stimulates muscle fibers differentiati...
