The Icelandic group's CBD tinctures come in two forms - Sleep, which is infused with spiced rose and lemon, and Wake, which has a citrus pine flavour.

Sleep is "formulated using premium ingredients selected to support your mind and body as you drift off into the ethereal", while Wake is "to help you align with the physical world. To be taken after waking or during the day for focus."

Each tincture contains 1000mg of full-spectrum hemp derived CBD.

A statement on the Vona site reads, "In Icelandic, Von loosely means "to hope". As the world spins ever faster, our collective hope is for a better life: healthier, less stressful, more benevolent and inspiring, for others and ourselves. Vona has been created specifically to address those aims."

This is the second CBD-infused product that Sigur Rós have released. Back in 2017, the band launched their CBD Wild Sigurberry gumdrops.
