What it's actually good for

Recovery

Weak Evidence

Preclinical data shows stimulation of cartilage matrix proteins, but human evidence is largely anecdotal.

Longevity

Weak Evidence

Mechanistic studies show downregulation of senescence markers in vitro, but longevity effects in humans are unproven.

How it works

Cartalax is a synthetic tripeptide (Ala-Glu-Asp) developed in Russia as a tissue-specific bioregulator for cartilage. Current evidence is primarily limited to preclinical models and Russian observational studies suggesting it may modulate chondrocyte gene expression.

Acts as a gene expression modulator that interacts with DNA sequences to stimulate protein synthesis in chondrocytes and normalize extracellular matrix homeostasis.

Safety

  • Limited long-term safety data in human clinical trials
  • Consult a physician if you have existing joint pathology or autoimmune conditions
  • Not evaluated by the FDA for safety or efficacy
