Recent studies demonstrate that SCFAs affect bone metabolism via the processes outlined ( Figure 2 ): Intestinal Epithelial Function and Mineral Absorption: SCFAs act on IECs to promote their development and differentiation, hence affecting the mechanical, chemical, immune, and biological barriers of the intestinal mucosa, regulating electrolyte exchange (such as between mineral ions and hydrogen ions), lowering luminal pH, and directly improving the absorption of minerals specially calcium (99, 100);Systemic Signaling via G protein-coupled receptors (GPCRs): Upon entering systemic circulation, SCFAs interact with GPCRs, influencing metabolism and function in peripheral tissues, including adipose tissue, skeletal muscle, bone, and liver (101);Epigenetic Regulation: SCFAs block histone deacetylases (HDACs), therefore contributing to the epigenetic regulation of gene expression, which may influence bone metabolism (102, 103);Modulation of Inflammatory Cytokines: SCFAs can modulate the production of inflammatory factors, therefore affecting bone remodeling (104)
N-acetyl cysteine N-acetyl cysteine (NAC) is a form of cysteine, which is an amino acid
Immune Boost
As a defined synthetic sequence rather than an extract, it is reproducible from lot to lot, and it is supplied strictly as a research material for in-vitro laboratory work by qualified professionals
It's easy to use, widely available, and for many people, it's the first treatment worth trying
