Revitalizing Sleep Formula by Enzymatic is a dietary supplement that promises to assist with various sleep problems, including to help you fall asleep faster and maintain a healthy sleep cycle, improve sleep quality for better energy levels the next day, and to rejuvenate the body during the sleep period.

The formula is an herbal mixture and claims to be non-habit forming, which is an excellent characteristic of any supplement of this kind. The manufacturing company Enzymatic Therapy is a manufacturer of supplements designed to help support optimum health in a variety of ways. From detoxification and cleansing formulations, to products targeting children health, the company is one of the most reputable manufacturers of dietary supplements in U.S. The formula was designed with Jacob Teitelbaum, M.D., recognized fatigue expert and author of the program “From Fatigued to Fantastic”.

The formula is designed to help healthy adults achieve optimum restorative sleep, and not to address more serious issues like insomnia. Pregnant and nursing women as well as those who already take drugs for other conditions should consult a specialist before use.


1) Quick Overview

The supplement features various botanical extracts well-established as sleep promoters or as able to diminish fatigue and restore proper energy levels. Among them there is the popular Valerian root extract, a plant that has been known for its therapeutic effects since the ancient Greece and Rome. It’s most common uses would involve its sedative, pain relieving, and anticonvulsant effects. It possesses tranquilizing effects; however the exact mechanism of work is unknown. The most popular theory is that it works in connection with the GABA neurotransmitter receptor system. Nonetheless, like all herbs, Valerian contains numerous chemical compounds any of which might produce the sedative effect. This is why there are no standardized doses available. The plant appears to be safe, although headache, nausea and diarrhea can occur.

Passiflora or Passion Flower is another chemical featured by the formula. Similar to the Valerian extract, this herbal extract too is hard to study because it contains many chemical compounds that might play roles in observed effects. One study on mice for instance which was published in May 2014 reported measurable sedative results using large doses of two different species of passion flower extracts. Although side effects are seemingly very poorly documented, some have reported dizziness, confusion and impaired gaits after using extracts of Passiflora.

Nutrition Facts

2) Revitalizing Sleep Formula Nutrition Facts

Revitalizing Sleep Formula contains the following ingredients: Valerian Root Extract standardized to 0.8% valerenic acids, Passionflower Leaf and Flower Extract, L-Theanine (Suntheanine brand), Hops Flower Extract, Wild Lettuce Leaf Extract, Lemon Balm Extract, vegetable capsule (modified cellulose), magnesium stearate, and silicon dioxide.

Valerian root is also popularly used in sleep supplements like Super Snooze.

3) Is Revitalizing Sleep Formula Right for You?

Fatigued to Fantastic! Revitalizing Sleep Formula is a mixture of several herbal extracts and amino acids. The website claims that this product is formulated with valerian root extract, which provides clinically demonstrated benefits for relaxation and restful sleep without morning grogginess. However, we were unable to find any relevant clinical studies on their website to support these claims. Furthermore, while the product is labeled as “lab tested,” the manufacturer does not cite any lab researches.

L-theanine appears to be the key ingredient here. Also known as gamma-glutamyl methyl amide, L-theanine is an amino acid commonly found in tea (infusions of Camellia sinensis), primarily in green tea. L-theanine can cross the blood-brain barrier, and several scientific studies have shown to have psychoactive properties. This amino acid is also believed to reduce mental and physical stress and improve cognitive function.

While the inclusion of L-theanine appears to be justified, we do not believe Valerian was a good choice. This herbal extract is usually used as an alternative to chemical sleeping or anti-anxiety drugs. However, the plant does have diuretic properties which, in the long term, may end up interrupting sleep and could cause headaches. In more severe situations, the treatment with Valerian Root may even lead to insomnia.

Bottom Line

8) Our Bottom Line

Healthy individuals can suffer from troubles falling asleep, staying asleep or getting back to sleep, and the number of causes and reasons is so vast that going about this issue is usually a matter of trial and error. Among the potential solutions, there are also herbal dietary supplements such as Revitalizing Sleep Formula, which attempts to offer support for the body to relax, enter sleep cycles, maintain them and replenish energy supply for a productive next day.

While for many it has worked, there are some who say no effects were noticed in the sense the formula should produce effects. This formula is designed with Jacob Teitelbaum, M.D., the author of the popular From Fatigued to Fantastic program, which is a great endorsement.
