Benfotiamine vs Collagen (Type I, II, III)

Mechanism

Lipid-soluble thiamine derivative that improves cellular thiamine availability and helps reduce advanced glycation stress in high-glucose environments.

Contraindications

• None established at standard doses

Mechanism

Hydrolyzed collagen peptides are absorbed as di- and tripeptides (primarily hydroxyproline-proline and hydroxyproline-glycine) via PepT1 transporters in the small intestine. These bioactive peptides accumulate in skin, cartilage, and bone where they stimulate fibroblast proliferation and extracellular matrix synthesis by upregulating collagen gene expression (COL1A1, COL3A1). They also inhibit MMP (matrix metalloproteinase) activity that degrades existing collagen, and stimulate hyaluronic acid production by dermal fibroblasts.

Standard Dosing

10-20g hydrolyzed collagen peptides daily

Timing

Any time; often added to morning coffee or post-workout shake. For joint support, take with vitamin C 30-60 min before exercise. Type II collagen (undenatured, UC-II) taken on empty stomach.

Cycle Duration

ongoing (minimum 8-12 weeks for visible results)

Side Effects

• Mild bloating
• GI discomfort
• Unpleasant taste
• Rare: calcium elevation (if calcium-containing marine source)
• Feeling of fullness

Contraindications

• Fish/shellfish allergy (if marine-sourced)
• Phenylketonuria (collagen contains phenylalanine)
• Histamine intolerance (bone broth collagen may be high in histamine)
