Here are my notes from a couple mionths ago on TUDCA
The most effective Bile salt is TUDCA.
TUDCA is just UDCA wth taurine molecule attached while UDCA can only be gotten only thru prescription and be way more expensive. There may be patents on UDCA.
Bile acids are the most potent agents which increase bile flow, especially unconjugated bile acids. Doses (13-15 mg/kg per day) UDCA becomes the predominant bile
UDCA stimulates biliary secretion of bile acids and other organic compounds (e.g. bilirubin glucuronides, glutathione conjugates, bromosulfophthalein)
Dosing of TUDCA and UDCA: 500mg daily for the maintenance of healthy liver function during the use of a C17AA oral during a cycle. 1,000mg or higher daily for the purpose of repairing the liver following heavy hepatotoxicity and hepatocyte damage from cholestasis (and/or for individuals with serious liver disorders).
IMPORTANT: Do not exceed 8 weeks of TUDCA/UDCA use, as it can increase negative cholesterol values. It is reccomended to use these bile salts only during a cycle of oral C17AA anabolic steroids, or for the purpose of liver repair following periods of significant hepatotoxicity from the use of these compounds. Other compounds should be sought after for general year-round liver support.
RESULTS:
The dose of 900 mg/day produced the greatest enrichment of UDCA in serum bile acids; although there was no difference in the enrichment of UDCA between the different doses. There was a trend towards normalization of the abnormal LFTs in a dose-dependent manner (for y-glutamyl transferase (yGT), alkaline phosphatase (ALP), alanine transaminase (ALT) and IgM). Multi-factorial analysis showed that UDCA treatment, irrespective of dose, was significantly better than placebo for all the variables. The 900 and 1200 mg doses were better than both 300 and 600 mg using yGT and total bilirubin as variables, better than 300 mg using ALP and IgM as variables, and better than 600 mg using albumin as a variable. No variables showed a significant difference between 900 and 1200 mg.
CONCLUSION:
The optimum dose of UDCA is 900 mg/day (equivalent to 13.5 mg/kg/day).
How to take Ursodeoxycholic Acid
Always take Ursodeoxycholic Acid exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.
The usual dose is between 3 and 4 tablets a day. The dose is usually divided up and taken twice a day, i.e. 1 or 2 tablets taken with water after meals. One of the doses should always be taken after your evening meal.
Ursodeoxycholic Acid will work best if taken together with a low cholesterol and calorie controlled diet. You should discuss this with your doctor.
You will not normally take Ursodeoxycholic Acid for more than 2 years. Your doctor will give you regular check-ups.
