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

Melatonin (N-acetyl-5-methoxytryptamine) is synthesized from serotonin in the pineal gland, regulated by the suprachiasmatic nucleus (SCN) via the retinohypothalamic tract. It binds MT1 and MT2 G-protein coupled receptors: MT1 activation suppresses neuronal firing in the SCN (sleep onset), while MT2 modulates circadian phase shifting. Beyond sleep, melatonin is a potent antioxidant that scavenges hydroxyl radicals, peroxynitrite, and singlet oxygen, and upregulates antioxidant enzymes (GPx, SOD, catalase) via Nrf2. It has anti-inflammatory properties (NF-kB suppression), immunomodulatory effects, oncostatic activity (anti-proliferative in several cancer types), and mitochondrial protective functions.

Standard Dosing

0.3-1mg for sleep onset (physiological); 3-5mg for jet lag; 10-20mg for oncological adjunct (under supervision)

Timing

30-60 minutes before desired sleep onset. For circadian phase advance: 4-6 hours before desired bedtime. Sublingual for faster onset. Dim lights 1-2 hours before taking.

Cycle Duration

Short-term for jet lag (3-5 days); ongoing at low dose for circadian support if needed; extended for oncological use under supervision

Side Effects

  • Morning grogginess (dose too high)
  • Vivid dreams/nightmares
  • Headache
  • Nausea
  • Dizziness
  • Reduced libido (at high chronic doses)
  • Next-day drowsiness
  • Depression (rare)

Contraindications

  • Autoimmune conditions (immunostimulatory)
  • Depression (may worsen in some individuals)
  • Seizure disorders (mixed data)
  • Pregnancy/lactation
