Deputy Assistant Commissioner Matt Twist said it is "sobering" to see the impact COVID-19 has had on health service workers across London.
He added: "But we are proud to be able to offer support to the London Ambulance Service at this critical time. At the heart of policing is the drive to save lives and keep people safe and I know officers volunteering to support the LAS will do so with pride and upmost professionalism.
"The Met has a long history of supporting our blue light colleagues across the city, responding to some of London's most challenging incidents.
"This partnership will see the Met provide 75 officers taken from a range of commands to drive ambulances to incidents across the capital
