Overview

Ovagen is a synthetic tripeptide consisting of Lysine-Glutamic acid-Aspartic acid (KED), developed as a bioregulator for liver and gastrointestinal tract tissue. It is closely related to Livagen (KEDA) but targets both hepatic and GI mucosal tissue. The Khavinson group's research suggests Ovagen modulates gene expression in hepatocytes and GI epithelial cells, supporting mucosal barrier integrity, digestive enzyme secretion, and hepatic detoxification function. It has been studied in models of toxic hepatitis, gastric ulceration, and age-related digestive decline. Available in Russia as oral capsules, Ovagen is positioned as a broader digestive system bioregulator compared to the liver-specific Livagen.

Key Takeaways: Ovagen

  • Research doses typically range from 5000 to 10000 mcg via oral capsule
  • 0 benefits with strong evidence, 0 moderate, 4 preliminary
  • Half-life: Minutes (typical of short peptides)
  • 3 cited research studies in this guide

Mechanism of Action

Ovagen is proposed to regulate gene expression in hepatocytes and GI epithelial cells through direct peptide-DNA interaction. In liver tissue, it upregulates genes involved in Phase I/II detoxification enzymes, albumin synthesis, and antioxidant defense (SOD, glutathione peroxidase). In GI tissue, Ovagen modulates expression of mucin genes (MUC2, MUC5AC) supporting mucosal barrier integrity, tight junction protein expression, and epithelial cell turnover. The peptide may also influence local immune function in gut-associated lymphoid tissue (GALT) by modulating IgA secretion and epithelial cytokine signaling. Age-related decline in digestive function is proposed to result from altered gene expression in GI and hepatic tissue, which Ovagen aims to normalize.

Concentration

50 mcg

per 0.1 mL (10 units)

Step-by-Step Guide

1

Gather Materials

Ovagen vial, bacteriostatic water, alcohol swabs, insulin syringes.

2

Equilibrate Temperature

Remove the vial from storage and allow it to reach room temperature (5-10 minutes).

3

Sanitize

Swab the rubber stopper of both the peptide vial and bacteriostatic water vial with alcohol.

4

Draw Water

Draw 2 mL of bacteriostatic water into a syringe.

5

Add Water to Vial

Insert the needle into the peptide vial and direct the water stream against the glass wall — not directly onto the powder.

6

Mix Gently

Swirl the vial gently until the powder is fully dissolved. Never shake. The solution should be clear and colorless.

7

Store Properly

Refrigerate at Refrigerated (2-8°C) after reconstitution. Up to 30 days refrigerated.

Frequently Asked Questions

Ovagen (KED) is a tripeptide bioregulator targeting both liver and GI tract tissue. It supports hepatoprotection, mucosal barrier integrity, and digestive function restoration.

Livagen (KEDA, 4 amino acids) is liver-specific with demonstrated chromatin decondensation. Ovagen (KED, 3 amino acids) targets both liver and GI tract more broadly. They are related but distinct peptides.

Evidence is primarily from Russian institutions at the preliminary level. Most data comes from cell culture, animal models, and clinical observations rather than controlled trials.
