  • Hydrolysed Collagen (Type I)
  • 2.5–10g
  • Supplies proline, glycine, hydroxyproline for dermal collagen synthesis
  • High. Peptides 2–10 kDa cross intestinal barrier intact
  • Gold standard for skin elasticity improvement; doses below 2.5g rarely produce measurable results in clinical trials
  • Reduced L-Glutathione (GSH)
  • 500–1000mg
  • Master antioxidant; neutralises ROS, reduces melanin production
  • Variable. Liposomal forms show superior absorption vs standard capsules
  • Essential for oxidative defence and skin tone evenness; sublingual or liposomal preferred over oral capsules
  • Buffered Vitamin C
  • 500–1000mg (split dose)
  • Cofactor for collagen crosslinking; regenerates oxidised glutathione
  • Moderate. SVCT1 transporter saturates at ~400mg/dose
  • Synergistic with both collagen and glutathione; split dosing critical for maximising absorption
  • Hyaluronic Acid (Low MW)
  • 120–240mg
  • Binds water in dermal matrix; increases skin moisture retention
  • Moderate. Low MW forms (<300 kDa) show better oral bioavailability
  • Clinically effective at lower doses than collagen; pairs well with collagen for comprehensive skin hydration
  • Ceramides (Oral)
  • 30–50mg
  • Restores lipid barrier function in stratum corneum
  • Low to moderate. Absorption enhanced with dietary fats
  • Emerging evidence for barrier repair; best used alongside hydration-focused peptides
  • Astaxanthin
  • 4–12mg
  • Potent antioxidant; protects against UV-induced collagen degradation
  • High. Lipophilic compound absorbed with dietary fats
  • Strong adjunct to glutathione for photoprotection; clinical doses start at 4mg daily
