Omega-3 (EPA/DHA) vs Pregnenolone

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

Pregnenolone is the 'master steroid' synthesized from cholesterol via CYP11A1 (side-chain cleavage enzyme) in adrenal glands, gonads, and brain. It serves as the biosynthetic precursor to all steroid hormones (progesterone, DHEA, cortisol, testosterone, estradiol, aldosterone). In the CNS, pregnenolone and its sulfated derivative (pregnenolone sulfate) function as potent neurosteroids: pregnenolone sulfate is a positive allosteric modulator of NMDA receptors enhancing glutamatergic neurotransmission, a negative modulator of GABA-A receptors (increasing neural excitability), and an activator of TRPM3 calcium channels. It also modulates sigma-1 receptors involved in neuroplasticity.

Standard Dosing

Research indicates 10-50 mg daily orally for neurosteroid and cognitive support. Clinical trials in schizophrenia used up to 500 mg/day.

Timing

Morning dosing preferred (aligns with diurnal cortisol rhythm). Sublingual may provide faster onset and better bioavailability. Take with or without food.

Cycle Duration

Ongoing with periodic reassessment. Cycle 5 days on / 2 days off, or 3-4 weeks on / 1 week off to prevent downstream hormone accumulation.

Side Effects

• Headache
• Irritability/mood changes
• Insomnia
• Acne (via androgenic metabolites)
• Heart palpitations
• Hair loss (if converting heavily down androgen pathway)
• Overstimulation
• Overstimulation and anxiety (from GABA-A antagonism at higher doses)
• Insomnia (if taken late in the day)
• Acne (from downstream androgen conversion)
• Irritability
• Hair growth or loss (from downstream hormonal changes)

Contraindications

• Hormone-sensitive cancers
• Seizure disorders (complex GABA modulation)
• Pregnancy
• PCOS
• Concurrent HRT without monitoring
• Use only with lab-guided supervision
• Hormone-sensitive cancers (breast, prostate, ovarian — due to downstream conversion)
• History of seizures (pregnenolone sulfate is pro-excitatory)
• Pregnancy and breastfeeding
• Bipolar disorder (may exacerbate manic episodes)
