FOXO4-DRI- Summary
- Collagen peptides are short-chain amino acid sequences produced by enzymatic hydrolysis of whole collagen (typically bovine or marine). They serve as bioactive signals that stimulate fibroblasts and chondrocytes to produce new collagen, elastin, and cartilage matrix, supporting skin, joint, bone, and gut health.
- FOXO4-DRI is a D-retro-inverso peptide derived from the FOXO4 protein that selectively induces apoptosis in senescent cells. By disrupting the FOXO4-p53 interaction that keeps senescent cells alive, it triggers programmed cell death specifically in these aging, pro-inflammatory cells while sparing healthy tissue.
- Half-Life
- N/A — food-derived; absorbed peptides circulate for hours, depot accumulation in tissues
- Estimated 2-4 hours (D-amino acid confers resistance to proteolysis)
- Admin Route
- Oral
- Subcutaneous, Intraperitoneal (research)

- Typical Dose
- 10–15 g
- 5 mg/kg in rodent studies; human equivalent approximately 0.5-1 mg/kg
- Frequency
- Once daily
- 3 consecutive days per cycle
- Key Benefits
- Stimulates skin collagen and elastin production
- Reduces wrinkle depth and improves skin hydration
- Supports joint cartilage regeneration
- Reduces joint pain in osteoarthritis
- Promotes bone density (stimulates osteoblasts)
- Improves gut barrier integrity (leaky gut)
- Supports hair and nail growth
- Excellent amino acid profile for muscle recovery
- Selectively clears senescent cells (senolytics)
- Reduces senescence-associated secretory phenotype (SASP) and chronic inflammation
- Demonstrated restoration of physical fitness in aged mice
- May improve healthspan and reduce age-related tissue dysfunction
- Potential for treatment of age-related pathologies driven by cellular senescence
- Does not affect healthy non-senescent cells at therapeutic doses
- Side Effects
- Excellent safety profile as food-derived protein
- Rare: bloating or GI discomfort at high doses
- Rare: allergic reaction (bovine or fish allergy)
- Mild bad taste (some forms)
- Limited human data; largely preclinical evidence
- Possible temporary inflammatory response as senescent cells are cleared (senolytic effect)
- Weight loss observed at high doses in rodent studies
- Unknown long-term safety profile in humans
