Citrus Bergamot ExtractPhosphatidylserine
CategorySupplementsSupplements
Standard Dose100-300mg daily
TimingWith 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 DurationOngoing; no cycling required. Clinical benefits observed from 6-12 weeks.
Evidence LevelModerate-Strongstrong_human

Mechanism

Contains brutieridin and melitidin — statin-like HMG-CoA reductase inhibitors from bergamot orange. Activates AMPK, improves lipid profiles (reduces LDL, increases HDL), and has antioxidant effects. Supports cardiovascular and metabolic health.

Contraindications

  • Rhabdomyolysis risk if combined with high-dose statins without monitoring
B

Phosphatidylserine

Supplements

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)
