Your glutathione starts dropping after 30

The video starts with a graphic of a human torso and liver, with text overlay. A man then appears in a small inset window, speaking directly to the camera. The background changes to show a microscopic view of a virus, then a website interface, then a close-up of skin cells, and finally a hospital hallway. The man's face is shown in close-up for most of the video, with varying expressions.
