The Ultimate Human Sleep Blend combines four research-backed ingredients that work together to support your body's natural sleep cycle. This science-driven formula helps you unwind at the end of the day and prepare for restorative rest.

Magnesium bisglycinate supports nervous system function and helps regulate neurotransmitters that promote relaxation. L-tryptophan serves as the building block for serotonin and melatonin, the hormones that control your sleep-wake rhythm.

Ashwagandha helps your body manage stress by supporting healthy cortisol levels, while L-theanine promotes a calm, focused state of mind. Created by human biologist Gary Brecka, The Ultimate Human brand brings over two decades of biomarker expertise to every formula.

Each ingredient is carefully selected to work with your body's natural processes—no sedatives, no habit-forming compounds, just clean support for better sleep. Comes in easy-to-take vegetarian capsules with 90 servings per bottle.
