Porcine Bile Powder
Also known as: Porcine bile acids, Bile powder from pigs, Pork bile powder, Porcine Bile Powder
Overview
Porcine bile powder is a supplement derived from the bile of pigs, containing key bile acids such as hyocholic, chenodeoxycholic, and hyodeoxycholic acids. It is used primarily as a digestive aid to improve emulsification of dietary fats and enhance absorption of fat-soluble vitamins (A, D, E). This powder enhances lipid digestion by increasing lipase activity, facilitating the hydrolysis of triglycerides into absorbable fatty acids and glycerol. Despite a moderate body of evidence supported by animal and in vitro studies demonstrating its digestive benefits, clinical trials on humans are scarce, indicating an urgent need for further research to validate its efficacy and safety in human populations.
Benefits
Porcine bile powder is best known for enhancing the emulsification of dietary fats and improving the absorption of fat-soluble vitamins. Studies in animal models, particularly feeding trials in laying hens, have shown that supplementation can lead to significantly better uptake of vitamins A, D, and E within 84 days, especially in low-fat diets that include 30-120 mg/kg of porcine bile acids. While some pre-clinical studies across broader neurological domains suggest potential benefits from bile acids, these findings do not apply specifically to porcine bile acids, highlighting the uncertainty in translating animal model results to human health outcomes.
How it works
Porcine bile acids enhance lipid digestion by acting as emulsifiers for dietary fats, improving the efficacy of lipase, the enzyme responsible for breaking down triglycerides into absorbable molecules: free fatty acids and glycerol. This process predominantly occurs in the small intestine, where the interaction of bile acids with lipid droplets increases the bioavailability of nutrients that depend on fat for absorption.
Side effects
Generally, porcine bile acids are thought to have a favorable safety profile based on existing animal studies. However, human data on side effects are lacking, with no common adverse effects reported (>5% incidence) and very few uncommon (<5%) or rare (<1%) side effects documented. Given this data gap, caution is prudent for individuals with existing liver or gallbladder conditions, as bile acid metabolism could be influenced. Pregnant or breastfeeding individuals and those with liver or gallbladder health issues should consult a healthcare professional prior to using porcine bile acids due to the insufficient safety data in these populations.
Dosage
Animal studies indicate a minimum effective dose of porcine bile acids at around 30 mg/kg of diet, with optimal dosages ranging between 30 and 120 mg/kg. However, specific guidelines for human dosages are not established. It is recommended to consume porcine bile powder with meals to enhance its digestive effects. The supplement is available in both powder and capsule forms, and its effectiveness is reliant on dietary fats and the presence of the enzyme lipase. Adequate safety thresholds or established upper limits for human consumption have yet to be defined.
