Omega-3 (EPA/DHA) vs Probiotics (Multi-Strain)

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)

Mechanism

Multi-strain probiotics colonize the gut mucosa and exert effects via multiple mechanisms: competitive exclusion of pathogens, production of short-chain fatty acids (butyrate, propionate, acetate) via fermentation of prebiotic fibers, strengthening of intestinal tight junctions (via occludin and zonulin modulation), modulation of gut-associated lymphoid tissue (GALT, ~70% of immune system), production of bacteriocins (antimicrobial peptides), and bidirectional gut-brain axis signaling via the vagus nerve affecting serotonin, GABA, and BDNF levels.

Standard Dosing

25-100 billion CFU daily (multi-strain, 8+ strains)

Timing

On empty stomach (morning before breakfast, or bedtime). Some strains survive better with food — follow specific product guidance.

Cycle Duration

ongoing

Side Effects

• Bloating/gas (usually transient, 1-2 weeks)
• Mild diarrhea during adjustment
• Brain fog or D-lactic acidosis (rare, with Lactobacillus overgrowth)
• Histamine intolerance flare (strain-dependent)

Contraindications

• Severe immunosuppression (risk of probiotic bacteremia/fungemia)
• Short bowel syndrome
• Central venous catheter (risk of Saccharomyces translocation)
• Acute pancreatitis (PROPATRIA trial warning)
