（1）Promote the digestion and absorption of lipids and lipophilic substances

　　Bile acids have hydrophilic and hydrophobic surfaces, strong surface activity, and can promote the emulsification of oils and expand the contact area between oils and lipases; Regulating the activity of pancreatic lipase and trypsin to enhance their hydrolysis metabolism of fats; Transporting fat in the intestine and promoting fat absorption.

　　（2）Protect the liver, gallbladder, and resist stress

　　▲ Activate the farnesol X receptor to promote liver tissue cell proliferation and liver regeneration;

　　▲ Promote bile secretion, eliminate heavy metals, drugs, toxins, etc., and detoxify the gallbladder;

　　▲ Maintain liver glucose and lipid metabolism balance, reduce fatty liver deposition and liver burden;

　　▲ Enhance antioxidant enzyme activity, eliminate oxygen free radicals, and improve stress resistance.

　　（3）Improve immunity

　　▲ Bile acids interact with immune cells throughout the body, regulating cytokine production and enhancing overall immunity.

　　（4）Maintain dynamic cholesterol balance

　　▲ The synthesis of bile acids is an important pathway for regulating cholesterol homeostasis.

　　▲ Inhibit cholesterol precipitation.

　　（5）Protecting intestinal health

　　▲ Free bile acids diffuse freely into the bacterial membrane, causing pH changes inside and outside the bacterial membrane for sterilization;

　　▲ Inducing genetic mutations in pathogenic bacteria, directly damaging DNA to induce death of pathogenic bacteria such as Escherichia coli and Salmonella, and inhibiting their intestinal proliferation;

　　▲ Change the permeability of bacterial cell membrane and internal and external osmotic pressure to induce autolysis of bacterial cells;

　　▲ Promote the secretion of antimicrobial peptides by intestinal epidermal cells, increase the number of beneficial bacteria in the intestine, and maintain the balance of intestinal microbiota.
