Phosphatidylserine (PS) vs Resveratrol

Mechanism

Phospholipid concentrated in brain cell membranes. Supports neurotransmitter production (acetylcholine, dopamine), cortisol regulation, and membrane fluidity. Improves cognitive function, reduces exercise-induced cortisol, and supports HPA axis recovery.

Contraindications

• Soy allergy (if soy-derived — use sunflower-derived instead)

Mechanism

Resveratrol activates SIRT1 (the longevity sirtuin) via allosteric binding, promoting deacetylation of PGC-1alpha (mitochondrial biogenesis), FOXO3 (stress resistance), and p53 (DNA repair). It inhibits NF-kB and COX-2, reducing chronic inflammation. Resveratrol also activates AMPK independently of SIRT1 and inhibits phosphodiesterases (PDEs), raising cAMP levels. It improves endothelial function via eNOS upregulation and NO production.

Standard Dosing

250-500mg trans-resveratrol daily

Timing

Morning with a fat-containing meal. Often taken alongside NMN for synergistic sirtuin activation.

Cycle Duration

ongoing

Side Effects

• GI upset/diarrhea at high doses
• Headache
• Joint pain (rare)
• Insomnia (if taken late)

Contraindications

• Estrogen-sensitive cancers (theoretical ER agonism)
• Bleeding disorders
• Pregnancy/lactation
