Yu Sleep uses a mix of botanical extracts, amino-acid-related compounds, B vitamins, magnesium, melatonin and GABA in its nighttime liquid formula. Each ingredient has a different role, from supporting relaxation and normal nervous-system activity to helping maintain the body’s natural sleep-wake rhythm.
Below, you can see what each Yu Sleep ingredient is, why it is included and how it fits into the overall formula.
