Is the word ringing a bell for you? Let us refresh your memory of GCSE science, if we may. Chlorophyll is found in plants – more specifically, it’s the green pigment found in the chloroplast.

“Chlorophyll is the stuff that helps absorb sunlight during a process called photosynthesis. This helps with generating energy for the plant to grow and survive,” says Kaitlin Colucci from The Mission Dietician. “It will be found naturally in your diet in your dark green leafy veggies such as spinach, kale, even things like wheatgrass – they are all really rich sources of chlorophyll.”

In the TikTok videos, most people are seen taking it as an over the counter supplement in a liquid form dropped into large glasses of water.
