Pregnenolone vs Serrapeptase

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)

Mechanism

Serrapeptase (serratiopeptidase) is a proteolytic enzyme originally isolated from the gut of the silkworm (Serratia marcescens). It hydrolyzes non-living tissue including fibrin, blood clots, cysts, and arterial plaque while sparing living tissue. It reduces bradykinin and other pain-mediating amines, provides anti-inflammatory effects by reducing neutrophil infiltration, and thins mucus by cleaving glycoprotein structures. It may also enhance antibiotic penetration into biofilms.

Standard Dosing

120,000-240,000 SPU (serratiopeptidase units) daily

Timing

On empty stomach (critical — food proteins will be digested instead of systemic absorption). 30+ minutes before meals or 2 hours after.

Cycle Duration

Cycle 4-8 weeks on, 2-4 weeks off

Side Effects

• GI discomfort
• Nausea
• Skin rash (rare)
• Muscle/joint pain (rare)
• Pneumonitis (very rare, case reports)

Contraindications

• Bleeding disorders
• Scheduled surgery (discontinue 2 weeks prior)
• Concurrent anticoagulant therapy
• Active peptic ulcers
• Active bleeding
• Pre-surgery
• Blood clotting disorders
