| Attribute | TUDCA | Cartalax |
|---|---|---|
| Category | Liver Support | Recovery |
| Research Stage | Preclinical | Preclinical |
| Mechanism of Action | TUDCA's mechanism of action operates through several distinct but overlapping pathways, making it unusual among bile acid therapeutics in having multiple pharmacologically meaningful modes of activity beyond simple bile-acid replacement. Pathway 1: Bile acid… | Mechanism of Action Cartalax's proposed mechanism is the Khavinson short-peptide framework applied to cartilage: passive membrane permeation, nuclear import, and sequence-selective chromatin modulation producing chondrocyte-favourable transcriptional shifts.… |
| Half-Life | — | No published human or animal pharmacokinetic data for Cartalax. As a small (~446.5 Da) tetrapeptide, rapid plasma hydrolysis (on the order of minutes) is expected, consistent with other Khavinson short peptides, but this has not been directly measured. |
| Typical Dose Range | — | 20 mg oral/sublingual once daily for 10 days; 60-90 day washout |
| Dosing Frequency | — | Once daily |
| Administration | — | — |
| Side Effects | TUDCA has an exceptionally favorable safety profile with decades of clinical use at the traditional cholestasis doses and accumulating safety data at the higher doses used in ALS trials. Common side effects (5-15% at typical doses 250-1,000 mg/day): - Mild… | Side Effects and Safety Cartalax has been used in Russian clinical settings for roughly 20 years with a sparse adverse-event literature — reassuring in direction, insufficient for confident pharmacovigilance.

Cartalax is a recovery that mechanism of action cartalax's proposed mechanism is the khavinson short-peptide framework applied to cartilage: passive membrane permeation, nuclear import, and sequence-selective…. The two differ in mechanism, half-life (not reported vs No published human or animal pharmacokinetic data for Cartalax. As a small (~446.5 Da) tetrapeptide, rapid plasma hydrolysis (on the order of minutes) is expected, consistent with other Khavinson short peptides, but this has not been directly measured.), and typical dose range.
Which has the longer half-life, TUDCA or Cartalax?
TUDCA has a half-life of not reported. Cartalax has a half-life of No published human or animal pharmacokinetic data for Cartalax. As a small (~446.5 Da) tetrapeptide, rapid plasma hydrolysis (on the order of minutes) is expected, consistent with other Khavinson short peptides, but this has not been directly measured.. Longer half-lives generally mean less frequent dosing but slower on/off kinetics.
Which is cheaper, TUDCA or Cartalax?
Lowest listed price on BodyHackGuide: TUDCA from $79.99, Cartalax from $58.85. Prices are pulled from the vendor listings tracked on BHG and change frequently. See the compare tables on each compound page for the current set of offers.
