Curcumin (with Piperine/Liposomal) vs Phosphatidylserine

Mechanism

Curcumin modulates over 100 molecular targets. Primary mechanisms include direct inhibition of NF-kB nuclear translocation (master inflammatory transcription factor), suppression of COX-2 and iNOS expression, inhibition of STAT3 and AP-1 signaling, and activation of Nrf2-ARE pathway upregulating Phase II detoxification enzymes (glutathione S-transferase, heme oxygenase-1). It also inhibits mTOR signaling and modulates epigenetic enzymes (HATs, HDACs, DNMTs).

Standard Dosing

500-1000mg curcuminoids daily (enhanced bioavailability form)

Timing

With meals containing fat. Piperine enhances absorption 2000% but also affects drug metabolism.

Cycle Duration

ongoing

Side Effects

• GI upset/diarrhea at high doses
• Yellow staining of teeth/skin
• Rare: contact dermatitis
• Potential iron depletion with chronic high-dose use

Contraindications

• Gallbladder obstruction/gallstones (stimulates bile flow)
• Iron-deficiency anemia (chelates iron)
• Scheduled surgery (discontinue 2 weeks prior)
• Pregnancy at therapeutic doses

Mechanism

Major phospholipid component of neuronal cell membranes (15-20% of total phospholipid pool) that maintains membrane fluidity and supports signal transduction. Serves as a cofactor for protein kinase C (PKC), Na+/K+-ATPase, and other membrane-bound enzymes critical for neurotransmitter release. Blunts HPA axis hyperactivation by modulating corticotrophin-releasing factor (CRF) receptor interactions, attenuating cortisol release during physical and psychological stress. Facilitates acetylcholine, dopamine, and norepinephrine release, and enhances glucose metabolism in the brain.

Standard Dosing

100-300mg daily

Timing

With meals (fat-containing preferred for absorption). Can be taken morning or evening. Cortisol-blunting effects are relevant for evening/pre-bed dosing in stressed individuals.

Cycle Duration

Ongoing; no cycling required. Clinical benefits observed from 6-12 weeks.

Side Effects

• Mild GI upset at high doses
• Insomnia (if taken too late in some individuals)
• Rare: nausea
• GI distress (uncommon)
• Insomnia (at higher doses)
• Headache (rare)

Contraindications

• Soy allergy (if soy-derived — use sunflower-derived instead)
• Known soy allergy (soy-derived PS)
• Antiphospholipid syndrome (theoretical concern)
