Berberine vs Omega-3 (EPA/DHA)

Mechanism

Berberine activates AMP-activated protein kinase (AMPK), the master metabolic sensor, mimicking many effects of caloric restriction and exercise. It inhibits mitochondrial Complex I, increasing the AMP:ATP ratio which triggers AMPK. Downstream effects include enhanced GLUT4 translocation (glucose uptake), inhibition of HMG-CoA reductase (cholesterol synthesis), upregulation of LDL receptor expression, and suppression of PCSK9. It also modulates gut microbiome composition, increasing short-chain fatty acid-producing bacteria.

Standard Dosing

500mg 2-3x daily (1000-1500mg total)

Timing

With meals or immediately before meals (reduces postprandial glucose spike). Must be taken with food.

Cycle Duration

Cycle 8-12 weeks on, 4 weeks off (or continuous under practitioner supervision)

Side Effects

• GI cramping/diarrhea (dose-dependent)
• Constipation in some
• Abdominal distension
• Potential for hypoglycemia

Contraindications

• Pregnancy (uterotonic — may induce contractions)
• Lactation
• Concurrent use of multiple CYP3A4 metabolized drugs
• Severe liver disease
• Children under 12

Mechanism

EPA and DHA incorporate into cell membrane phospholipids, modulating membrane fluidity and lipid raft signaling. EPA competitively inhibits arachidonic acid conversion via COX-2 and 5-LOX, reducing pro-inflammatory eicosanoids (PGE2, LTB4) while generating anti-inflammatory resolvins and protectins. DHA is critical for neuronal membrane integrity, modulating BDNF expression and synaptic plasticity via Nrf2 and NF-kB pathways.

Standard Dosing

2-4g combined EPA/DHA daily (targeting 2:1 EPA:DHA ratio for inflammation; 1:1 for cognitive)

Timing

With meals containing fat for absorption. Split dose AM/PM.

Cycle Duration

ongoing

Side Effects

• Fishy burps/aftertaste
• Mild GI upset
• Loose stools at high doses
• Potential increased LDL in some individuals

Contraindications

• Active bleeding disorders
• Scheduled surgery (discontinue 2 weeks prior)
• Fish/shellfish allergy (use algal-derived)
