Digestive Enzymes (Broad Spectrum) vs Melatonin

Mechanism

Broad-spectrum digestive enzyme complexes supplement endogenous pancreatic and brush border enzyme production. Key enzymes include: lipase (triglyceride hydrolysis to fatty acids/glycerol), protease/peptidase (protein to amino acids via peptide bond cleavage), amylase (starch to maltose/glucose), lactase (lactose to glucose/galactose), cellulase (plant fiber breakdown), and invertase (sucrose hydrolysis). They reduce osmotic load in the small intestine, decrease bacterial fermentation of undigested substrate, and improve nutrient bioavailability.

Standard Dosing

1-2 capsules with each main meal

Timing

Immediately before or at the start of each meal. Not needed for small snacks.

Cycle Duration

ongoing as needed

Side Effects

• GI cramping if taken without food
• Allergic reactions (rare)
• Mouth ulcers from chewing enzyme capsules
• Perianal irritation from lipase at very high doses

Contraindications

• Acute pancreatitis
• Known allergy to enzyme sources (porcine, fungal, fruit-derived)

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
