Our microalgae are grown with craft and science on our Kona Coast farm—allowing us to ensure consistent purity and high quality. It’s a special place for a farm and a lot of it is in every bottle. Thanks to our location on the Kona Coast, our microalgae thrive under a year-round sun. It’s here every day, and so are we—grateful to share a bountiful harvest.
