Primary Biliary Cholangitis

The bile ducts are tubes that move bile — a substance that helps with digestion — from the liver to the small intestine. Primary biliary cholangitis is a chronic disease in which the bile ducts in the liver become injured and inflamed and are eventually destroyed.

Quick Answer

What it is

The bile ducts are tubes that move bile — a substance that helps with digestion — from the liver to the small intestine. Primary biliary cholangitis is a chronic disease in which the bile ducts in the liver become injured and inflamed and are eventually destroyed.

Evidence-Based Protocol

Supplement stack ranked by research quality

Moderate Evidence

Primary Stack (Tier 1)

Vitamin DA
2000-4000 IU daily (higher if deficient; may need prescription doses)

Commonly deficient due to fat malabsorption; critical for bone health (osteoporosis risk high in PBC)

15 studies | 800 participants
CalciumA
1000-1200mg daily with meals

Important for bone health; may be poorly absorbed; osteoporosis prevention

12 studies | 600 participants

Supporting Stack (Tier 2)

Vitamin AB
10,000-25,000 IU daily (monitor levels; avoid excess)

Fat-soluble vitamin often deficient in PBC; supports vision and immune function

8 studies | 300 participants
Vitamin EB
400-800 IU daily (water-soluble form if malabsorption severe)

Fat-soluble vitamin deficiency common; antioxidant; may help with neuropathy

8 studies | 300 participants
Vitamin KB
2.5-10mg daily or based on INR

Often deficient; essential for coagulation; may need monitoring

8 studies | 300 participants
Omega-3 Fatty AcidsC
2-3g EPA+DHA daily

Anti-inflammatory; may help with hypertriglyceridemia common in PBC

6 studies | 200 participants
SAMe (S-Adenosyl-L-Methionine)C
800-1600mg daily

Supports liver methylation and glutathione; some evidence in cholestatic liver disease

5 studies | 150 participants
Milk Thistle (Silymarin)C
420-600mg silymarin daily in divided doses

Traditional hepatoprotective herb; antioxidant; limited evidence in PBC specifically

5 studies | 150 participants

How It Works

Primary Biliary Cholangitis (PBC), formerly called Primary Biliary Cirrhosis, is an autoimmune disease where the body's immune system attacks the small bile ducts in the liver. This leads to bile buildup, which damages the liver over time.

KEY FEATURES:

•Primarily affects women (90%)
•Usually diagnosed ages 40-60
•Positive anti-mitochondrial antibodies (AMA) in 95%
•Slowly progressive
•Can lead to cirrhosis if untreated

COMMON SYMPTOMS:

•Fatigue (most common, often debilitating)
•Itching (pruritus) - can be severe
•Dry eyes and mouth (Sicca syndrome)
•Right upper abdominal discomfort
•Jaundice (later stage)
•Bone pain (osteoporosis)

CRITICAL: PBC requires medical treatment with ursodeoxycholic acid (UDCA) - this is the cornerstone therapy. This protocol is SUPPORTIVE ONLY.

STANDARD TREATMENT:

•UDCA: First-line treatment; slows progression
•Obeticholic acid: For inadequate response to UDCA
•Fibrates: May help some patients (bezafibrate, fenofibrate)
•Symptom management: Cholestyramine for itching
•Liver transplant: For advanced disease

ASSOCIATED CONDITIONS:

•Osteoporosis (common and serious)
•Fat-soluble vitamin deficiencies (A, D, E, K)
•Thyroid disease
•Sjogren's syndrome
•Celiac disease

* Vitamin D and Calcium are critical for bone health.

* Fat-soluble vitamins (A, D, E, K) often need supplementation.

* Monitor bone density regularly and treat osteoporosis if present.

Expected timeline: PBC is a chronic disease. UDCA can significantly slow progression. Life expectancy normal or near-normal with early treatment and good response.

Obesity is a condition of excessive body fat that increases the risk for other conditions such as diabetes and heart disease. Fat is how the body stores extra calories that were eaten but not used. Obesity treatment usually involves restricting the calories eaten or creating a negative calorie balance.

Cirrhosis

1 shared supplement · 12 outcomes

Liver cirrhosis is a severe form of liver disease characterized by the replacement of healthy tissue with scar tissue, resulting in impaired liver function.

Chronic Liver Disease

1 shared supplement · 17 outcomes

Chronic liver disease is a progressive loss of liver functions for a period longer than 6 months. Chronic liver disease is caused by inflammation and destruction of liver cells that ultimately causes a hardening (fibrosis) and scarring (cirrhosis) of the liver.
