product information

5-HTP from Griffonia seed to help increase brain serotonin levels

5-HTP is the precursor to serotonin, the neurotransmitter responsible for happiness. Because of this role in creating serotonin, 5-HTP is also indirectly involved in producing melatonin, a hormone critical for sleep. Melatonin helps the body’s bio clock stay in sync and regulates daily sleep-wake cycles. Regular sleep-wake cycles are the foundation for restful and rejuvenating sleep. Research also suggests that 5-HTP may help shorten sleep onset time and increase sleep duration. Our 5-HTP is from Griffonia seed, a West African shrub1.

Calming Amino Acids L-Glycine and L-Theanine

We’ve included the calming Amino Acids L-Glycine and L-Theanine. L-Glycine has been shown to reduce sleep onset time and sleep quality while L-Theanine helps promote relaxation.2.

Essential dietary minerals Magnesium and Zinc

Magnesium deficiencies are common in developed countries and a lack of magnesium can raise blood pressure and reduce insulin sensitivity. People with low magnesium levels often experience restless sleep, whereas healthy magnesium levels often lead to deeper, better sleep. Magnesium also plays a role in supporting sleep by maintaining levels of GABA, a neurotransmitter that promotes sleep.3

Zinc is an essential mineral and antioxidant involved in many enzyme processes. Recent research has shown that zinc levels vary with sleep quantity and zinc supplementation can increase both sleep amount and quality.4

BioPerine® to improve adsorption

You aren’t what you eat, you are what you absorb, and much of the goodness from food and supplementation can be lost through poor nutrient absorption.

We ensure you get maximum benefits from ZZZZs with an effective dose of BioPerine®, an extract from black pepper proven to increase bioavailability (absorption of nutrients).
