Restful sleep can be so easy.

Many people struggle with restless sleep, problems falling asleep or waking up at night. This is exactly where *Sleeplike a Bull* comes in. The novel active ingredient matrix specifically combines ingredients that work synergistically to take your sleep to the next level - without artificial sedatives or side effects.

What makes Sleep like a Bull so effective?

Myo-inositol & L-theanine This combination supports GABA and serotonin regulation - two neurotransmitters that are essential for relaxation and restful sleep. Studies show that L-theanine shortens the time it takes to fall asleep and prolongs deep sleep phases (1,2,3,4,5).

Magnesium & vitamin B6 Insomnia can be exacerbated by magnesium and vitamin B6 deficiency. Both substances are essential for melatonin production, the hormone that controls your sleep-wake cycle (6,7,8,9).

Apigenin - the herbal sleep aid Studies have shown that apigenin has a calming effect on the nervous system (12,13). Studies also suggest that apigenin can have a positive effect on brain function (14,15), oxidative stress (16), inflammation (17,18) and the hormone regulation of testosterone, oestrogen and cortisol (19,20,21).

Saffron extract - for deep and restful sleep Saffron has been shown to increase serotonin levels and reduce stress hormones, which promotes peaceful, undisturbed sleep. Studies suggest that saffron may increase sleep duration and improve sleep quality (22,23).

Zinc & boron - for hormone balance Zinc and boron are involved in various processes in the body, including sleep and normal brain function (24, 25).

Conclusion - sleep like a bull

With *Sleeplike a Bull* you get a specifically developed formula that can help you fall asleep faster, sleep longer and wake up full of energy in the morning. No more tossing and turning - just deep, restful sleep. GN Laboratories and German Bull have teamed up to create an innovative sleep supplement that can help you optimize your recovery.
