Glycocholic Acid
Also known as: Glycocholate, Bile Glycine Conjugate, Glycocholic Acid
Overview
Glycocholic acid (GCA) is a conjugated bile acid synthesized in the liver through the conjugation of cholic acid with glycine. It is naturally produced within the human body and plays a crucial role in the digestion and absorption of dietary fats, as well as fat-soluble vitamins. Its water-soluble nature enhances these functions, promoting metabolic regulation and homeostasis. GCA participates in various physiological processes, including energy metabolism, and has been studied in connection with multiple metabolic diseases. Research, including systematic reviews and meta-analyses, provides robust evidence supporting its role in liver and metabolic health, highlighting its therapeutic potential in conditions like nonalcoholic fatty liver disease (NAFLD) and metabolic dysfunction.
Benefits
Glycocholic acid is associated with several evidence-based benefits. For nonalcoholic fatty liver disease (NAFLD), a lower GCA-to-total bile acid ratio is indicative of the disease presence (p ≤ 0.01). It has been proposed as a potential biomarker, as evidenced by elevated GCA levels in patients with gallstone disease (WMD = 0.83 μmol/L, 95% CI = 0.06; 1.6) and in metabolic dysfunction-associated steatohepatitis (MASH). Additionally, GCA contributes to energy metabolism, with higher levels correlating with metabolic dysfunction-associated liver diseases, making it significant for understanding metabolic health.
How it works
Glycocholic acid interacts with the farnesoid X receptor (FXR) and the G protein-coupled bile acid receptor 1 (TGR5), which are critical in regulating bile acid synthesis, lipid metabolism, and energy homeostasis. GCA promotes fat emulsification, facilitating efficient digestion and absorption of dietary fats while influencing liver function through the regulation of bile acid levels and lipid metabolism. Its enterohepatic circulation—a process where it is secreted into the intestine and reabsorbed—further emphasizes its role in metabolic processes.
Side effects
Glycocholic acid is generally safe when produced within normal physiological limits, with no common side effects reported (>5%). There are no documented uncommon or rare side effects specifically linked to GCA usage. Although specific drug interactions are not well-documented, GCA may potentially interact with medications affecting bile acid metabolism or liver function. No contraindications for GCA have been identified, but it is important to recognize that individuals with liver or gallbladder diseases may show altered GCA levels, serving primarily as a diagnostic indicator rather than implying direct safety risks.
Dosage
There are currently no established dosages for Glycocholic acid supplementation due to its natural synthesis in the body. Consequently, no recommended effective or maximum dosage ranges exist. GCA operates within physiological levels naturally occurring in the human body, and considerations for specific timing or form are not applicable. The absence of supplemental forms means that absorption factors are inherently tied to the body's metabolic processes, emphasizing the importance of maintaining normal physiological GCA levels.
FAQs
Is Glycocholic acid safe to use?
Yes, GCA is generally safe since it is a naturally occurring bile acid.
What results can be expected from GCA levels?
Altered GCA levels can indicate metabolic conditions such as NAFLD or gallstone disease.
How does GCA interact with fat digestion?
GCA helps emulsify fats, aiding in their absorption in the intestine.
