Microbz Sleep is the UK's first liquid sleep supplement with bio live cultures. Sleep is essential for recovery, renewal and rebalance. Research is illuminating the crucial link between a healthy gut and a good night’s sleep. The quality of your sleep and the health of your microbiome are intricately linked, and research surrounding the connection of a healthy gut and a good night’s sleep, is ever growing. 

What's inside:

Live active cultures: your gut, also known as your second brain, is key to supporting your overall health. Beneficial microbes in your gut are vital for digestion, breaking down toxins, producing vitamins and supporting your immune system.

Chamomile: Used for years to reduce anxiety and treat insomnia, chamomile has long been recognised as a natural health remedy to settle your mind.

Oat Straw: One of the best calming herbs, mellow your mood with gentle oat straw. Historically used as a remedy for exhaustion and to strengthen the nervous system

Valerian: Used for thousands of years to promote relaxation and encourage healthy sleeping patterns. Valerian is known to interact with GABA, a chemical messenger which regulates nerve impulses in your brain and nervous system.
