The journalist shared a video report in a joint post with BBC Radio 5 Live, which documented her experience donating blood.
While the star made the trip to the Oxford blood donation centre back in February, the finished report detailed the journey of the blood donations, including the stage where it's separated into red blood cells, platelets and plasma, before being stored in fridges at a temperature of four degrees and finally transported to the people who need it.
The caption read: "What happens after you've given a blood donation? As a regular blood donor, Naga Munchetty has asked herself this question countless times. After she gave blood on BBC Radio 5 Live we followed the journey donations just like hers go on. Here's what it looks like…"
Naga's followers were quick to praise the star in the comments section, with one person hailing the post as "inspirational". Another person wrote: "Well done for sharing this. So important," while another added: "Well documented, very interesting and learnt something new, thank you."
A fourth follower commented: "Great work here from Naga, saving lives!"
The post comes a day after Naga showed her support for her fellow BBC Breakfast co-star Nina Warhurst after she received criticism from a viewer.
Hitting back at a negative comment which said Nina's hair looked "a mess", she responded on Twitter: "Women who do this to women. Too repulsed by my hair to eat her breakfast, but managing to bang out this vitriol. Apart from anything else I can't bear inaccuracies - I think we can all agree my hair looked [heart hands emoji]."
Naga was quick to rally around her co-star, commenting: "It looked fab x."
Naga - who is married to TV director James Haggar - appears on BBC Breakfast every week from Thursdays to Saturdays, and also hosts a BBC Radio 5 show from Monday to Wednesday.
She also recently wrapped filming for the latest series of her BBC documentary, Claimed and Shamed, which exposes the growing problem of insurance fraud.
