Menatetrenon (MK4) je menahinonsko jedinjenje koji se koristi kao hemostatički agens i kao dopunska terapija za bol uzrokovan osteoporozom. On je u prodaji za tu tretman osteoporoze u Japanu pod imenom Glakaj.

Menatetrenon jedna od devet formi vitamina K₂.^[4]

MK4 se formira konverzijom vitamina K₁ u telu, testisima, pankreasu i arterijskim zidovima.^[5] Mada biohemijski put transformacije vitamina K₁ u MK4 nije potpuno razjašnjen, studije sugerišu da konverzija nije zavisna od bakterija u crevima.^[6]^[7]^[8]^[9] Tkiva koja akumuliraju velike količine MK4 imaju veliki kapacitet konvertovanja dostupnog K₁ u MK4.^[10]^[11]
