About Nooroots
Nooroots is a UK brand of natural nootropic supplements, founded in London in 2022. Its mission is to support everyday progress, helping people feel clear, calm and capable of doing what they set out to do. It began with a question about how small daily habits shape the way we think, feel and function, and the part plants can play when they're used thoughtfully.
Nooroots chooses each ingredient on the published human studies, puts every dose on the label and makes its supplements in the UK. It also publishes the Ingredient Atlas, a free record of the research on ingredients used in brain and sleep supplements, and free caffeine and magnesium calculators.
