Activation of these receptors triggers two complementary processes: it accelerates lipolysis (the breakdown of stored triglycerides into free fatty acids for energy) while simultaneously inhibiting lipogenesis (the conversion of glucose and other substrates into new fat stores)
While individual hypersensitivity cannot be entirely eliminated, the clinical trial evidence is highly reassuring
Methionine, inositol, and choline are not typically supplemented orally at therapeutic doses in isolation, so the MIC component still adds value even if B12 is covered
