Mechanism

ALA is a dithiol compound that functions as a cofactor for mitochondrial alpha-keto acid dehydrogenases (pyruvate dehydrogenase, alpha-ketoglutarate dehydrogenase). Both ALA and its reduced form DHLA are potent antioxidants capable of regenerating other antioxidants including vitamin C, vitamin E, and glutathione. ALA activates AMPK, improving glucose uptake via GLUT4 translocation, and modulates NF-kB-mediated inflammatory signaling. It chelates redox-active metals (Fe2+, Cu2+).

Standard Dosing

300-600mg R-ALA daily

Timing

On empty stomach, 30-60 min before meals. Split doses for higher amounts.

Cycle Duration

ongoing or cycle 12 weeks on, 4 weeks off

Side Effects

  • GI upset/nausea
  • Skin rash
  • Hypoglycemia symptoms
  • Body odor changes

Contraindications

  • Thiamine (B1) deficiency (ALA increases thiamine demand)
  • Hypoglycemia-prone individuals without monitoring
  • Autoimmune thyroid conditions (monitor thyroid function)

Mechanism

Multi-strain probiotics colonize the gut mucosa and exert effects via multiple mechanisms: competitive exclusion of pathogens, production of short-chain fatty acids (butyrate, propionate, acetate) via fermentation of prebiotic fibers, strengthening of intestinal tight junctions (via occludin and zonulin modulation), modulation of gut-associated lymphoid tissue (GALT, ~70% of immune system), production of bacteriocins (antimicrobial peptides), and bidirectional gut-brain axis signaling via the vagus nerve affecting serotonin, GABA, and BDNF levels.

Standard Dosing

25-100 billion CFU daily (multi-strain, 8+ strains)

Timing

On empty stomach (morning before breakfast, or bedtime). Some strains survive better with food — follow specific product guidance.

Cycle Duration

ongoing

Side Effects

  • Bloating/gas (usually transient, 1-2 weeks)
  • Mild diarrhea during adjustment
  • Brain fog or D-lactic acidosis (rare, with Lactobacillus overgrowth)
  • Histamine intolerance flare (strain-dependent)

Contraindications

  • Severe immunosuppression (risk of probiotic bacteremia/fungemia)
  • Short bowel syndrome
  • Central venous catheter (risk of Saccharomyces translocation)
  • Acute pancreatitis (PROPATRIA trial warning)
