What Is GB-3?
GB-3 is a practitioner-exclusive bile acid and detoxification support supplement from Endo-met Laboratories — the pioneer of Hair Tissue Mineral Analysis (HTMA)-guided supplement protocols. GB-3 stands apart as one of the most targeted and clinically useful liver-gallbladder support formulas available, particularly valued for:

Copper detoxification — Endo-met protocols are particularly focused on addressing copper toxicity and biounavailability, and GB-3 is a cornerstone of copper removal protocols
Bile acid stimulation — Supports bile production and flow, improving fat digestion, fat-soluble vitamin absorption, and elimination of toxins through the biliary route
Drainage support — Opens the body's primary hepatic drainage pathway before and during detox or antimicrobial protocols to prevent toxin recirculation


Who Needs GB-3?
Michelle Tonkin ND recommends GB-3 for patients with:

Copper toxicity / excess copper detected via HTMA (hair tissue mineral analysis) — one of the most common mineral imbalances in modern patients
Poor fat digestion — nausea after fatty meals, light-colored stools, fat-soluble vitamin deficiencies
Gallbladder dysfunction — sluggish bile, gallbladder removal, biliary stasis
Liver detox support — before and during any detox, antimicrobial, or heavy metal protocol
SIBO / gut dysbiosis — bile deficiency is a major driver of bacterial overgrowth in the small intestine
Lyme disease / chronic illness protocols — drainage optimization is critical before starting antimicrobial therapy
Hormonal imbalances — bile is necessary for estrogen metabolism and conjugation
HTMA slow oxidizer patterns — GB-3 is a foundational supplement in Endo-met's slow oxidizer programs


Key Ingredients

Ox Bile (purified bile salts) — Replaces or supplements endogenous bile; directly improves fat digestion and stimulates biliary flow
Pancreatin — Digestive enzyme complex that works synergistically with bile for complete fat, protein, and carbohydrate digestion
Betaine HCl — Supports stomach acid production needed to trigger bile and pancreatic enzyme release
Pancreatic Lipase (concentrated) — Specifically targets fat digestion, reducing the burden of fat malabsorption

Endo-met products are formulated based on decades of HTMA mineral research. Full ingredient list on product label.

Why Drainage Comes First
A fundamental principle in Michelle Tonkin ND's protocols: you must open drainage pathways before beginning any detox or antimicrobial protocol. If bile flow is sluggish and the liver-gallbladder pathway is backed up, toxins and pathogens being killed off have nowhere to exit — they recirculate, causing worsening symptoms (Herxheimer reactions) and reabsorption of biotoxins.
GB-3 ensures the biliary drainage pathway is open and functional, making it an essential first-line supplement in any comprehensive detox, Lyme, or antimicrobial protocol.

How to Use GB-3

Standard dose: 3 capsules with each meal (with breakfast, lunch, and dinner) — 9 capsules daily
Reduced maintenance dose: 1–2 capsules with larger or fattier meals
Duration: Ongoing maintenance appropriate for gallbladder removal patients or copper detox protocols
180-cap bottle: Approximately 20-day supply at full dose; 60+ day supply at maintenance dose

⚠️ Caution: Do not use if you have active bile duct obstruction, acute cholecystitis, or are allergic to bovine products. Consult your healthcare provider before use.

Frequently Asked Questions
Q: Do I need an HTMA test before taking GB-3?
A: An HTMA provides the most targeted protocol guidance, but GB-3 can also be recommended based on clinical symptoms of poor bile flow, fat malabsorption, or copper excess. Book a free 10-minute consultation with Michelle Tonkin ND for personalized guidance.
Q: What is copper toxicity and how do I know if I have it?
A: Copper toxicity (or biounavailable copper) is identified through HTMA. Symptoms can include fatigue, mood swings, brain fog, estrogen dominance, and sensitivity to copper-containing foods (chocolate, nuts, shellfish). Michelle Tonkin ND specializes in HTMA interpretation and copper detox protocols.
Q: Can I take GB-3 if I've had my gallbladder removed?
A: GB-3 is particularly beneficial for patients without a gallbladder, as it provides the bile salts the gallbladder would normally store and release. Many post-cholecystectomy patients notice dramatic improvement in digestion and energy with GB-3 supplementation.
Q: What is the difference between the 90-cap and 180-cap sizes?
A: Same formula, different bottle sizes. The 180-cap size offers better value for ongoing maintenance protocols. The 90-cap is ideal for shorter-term use or first-time buyers.
