A baby interacting with a dog and a man looking down.

The video opens with a man looking down at a baby and a dog. The scene transitions to a woman tying her running shoes next to a treadmill. Then, a close-up shows a hand opening a box with the Thrva logo and instructions. The next shot is a person holding a smartphone displaying health data, including hormones, metabolism, defense, and mind metrics. A graph shows a trend for 'Active B12' with recommendations to add B12-rich foods. The video then shows a woman with a small device attached to her arm, brushing her teeth. Finally, a man with a similar device on his arm is in a kitchen, preparing a drink. The ad ends with the Thrva logo and tagline.
