End Fatigue Revitalizing Sleep Formula

by Integrative Therapeutics Inc

End Fatigue Revitalizing Sleep Formula is a combination of herbal ingredients that promote relaxation and restful sleep.*

Valerian (Valeriana officinalis) root extract has been clinically demonstrated to support restful sleep.* 1–7 It has an approved monograph in both The German Commission E and the World Health Organization (WHO) Monographs on Selected Medicinal Plants.8,9

Passionflower (Passiflora incarnata) extract has been studied for its ability to calm simple nervous tension that may lead to occasional sleeplessness.* It has an approved monograph in the German Commission E.10 Passionflower extract has been reported to have calming effects in clinical trials.* For example, in a double-blind randomized controlled trial, subjects reported that passionflower extract was effective in calming restlessness.*11

L-Theanine is a key ingredient in green tea. Since ancient times, it has been said that drinking green tea brings relaxation. L-theanine's effect on brain amino acids and neurotransmittors has been investigated. L-theanine appears to modulate neurotransmitter concentrations in brain, such as serotonin and dopamine, promoting muscle relaxation and improving sleep.*12

In a clinical trial in humans, the brain activity of 50 volunteers was measured after the oral administration of 50–200 mg of L-theanine. L-theanine promoted the generation of alpha-brain waves, considered to be an index of relaxation, in the volunteers.* Researchers concluded that L-theanine promotes relaxation in humans by increasing alpha brain waves.*13

Hops (Humulus lupulus) extract has been shown to calm restlessness and can be used to support restful sleep.* It has an approved monograph in The German Commission E.14 The dried strobile of Hops is a popular sleep aid. While hops have been used for centuries for gastrointestinal health support, they have more recently been used to support healthy sleep.* Key constituents of hops include a volatile oil, valerianic acid, phytoestrogenic substances, tannins, and flavonoids. Hops extract, in combination with valerian, has been clinically demonstrated to improve sleep.* 15,16

Wild lettuce (Lactuca virosa) has been used in traditional medicine for its calmative effect.* Wild lettuce has been found to contain the key components of lactucic acid, lactucone, and lactucopicrin. Wild lettuce supports restful sleep by promoting a relaxed feeling.*17

Jamaica Dogwood (Piscidia piscipula) root contains isoflavonoids and tannins that help promote restful sleep.* This herb helps individuals fall asleep and promotes musculoskeletal relaxation.* This botanical ingredient has also been found to resolve nervous irritability, thus promoting quality sleep.*18
