Serinytex® ( pronounced sah-rhen-ahtex ) is a proprietary formulation designed to support a restful night sleep. It is a synergistic blend of herbs , amino acids and melatonin formulated by Dr. Germaine Hawkins, DO, psychiatrist. Dr.Hawkins encourages sleep hygiene, exercise and a balanced nutritional diet to promote optimal health. You should avoid overly-stimulating activities including electronics (i.e tablets, smartphones, television) while in bed, caffeinated beverages and carbohydrates or sugary foods within three hours of sleep onset. In the event you desire an all natural complementary option to support a restful night’s sleep , Serinytex may be for you!

Sleep disorders are vastly underreported, and there are likely many more than 70 million Americans who are not getting adequate sleep. Only a third of Americans get the recommended 7 to 9 hours of sleep a night.

An estimated 30%-50% of the general population is affected by insomnia, and 10% have chronic insomnia. Insomnia affects all age groups. Among adults, insomnia affects women more often than men.

Serinytex® is NOT a drug. Nor is it FDA approved for insomnia or any sleep disorders Serinytex was designed with the idea of synergy – combining well studied and researched amino acids, herbs and melatonin- all which individually have shown some benefits in sleep support. Serinytex contains melatonin, glycine, L-theanine, valerian root, passion flower extract and lemon balm extract. Dr. Hawkins chose the included ingredients based on their known calming, anxiety-reducing and potential ability to enhance GABA and serotonin production.


is a hormone made by the pineal gland, a small gland in the brain. Melatonin helps control your sleep and wake cycles. Very small amounts of it are found in foods such as meats, grains, fruits, and vegetables. Natural melatonin levels slowly drop with age. Some older adults make very small amounts of it or none at all.

Benefits of Melatonin

  • Helping to control sleep patterns for people who work night shifts.
  • Preventing or reducing problems with sleeping and confusion after surgery.
  • Reducing chronic cluster headaches.
  • Treating seasonal affective (SAD).


High serotonin levels are associated with being awake, but erratic sleep and stress can disrupt serotonin production and cause sleep disorders, like insomnia and apnea. Serotonin may make up for that loss and help people with a sleep disorder get more sleep. To be more specific, when serotonin accesses the dorsal raphe nucleus (DRN) part of the brain, it’s able to activate its receptors and increase (REM) sleep.

Glycine has been found to increase serotonin levels in the prefrontal cortex which may help to alleviate sleep issues and maintain behavioral sleep. Some possible benefits of glycine include

  • Improving subjective sleep quality. Glycine may increase sleep efficiency and decrease sleep onset latency.
  • Supporting Deep Sleep Reduced drowsiness and enhanced cognitive performance with glycine point to solid rest.
  • Reducing insomnia. Glycine amino acid reportedly boosts serotonin levels and accordingly reduces insomnia.

Glycine is also believed to lower core body temperature and to relax blood vessels at night; both these biological activities have been tied to sleep onset and sleep quality.


An amino acid found in green tea, L–theanine has a calming effect because it reduces levels of the stress hormones cortisol and epinephrine. When taken before bedtime, L–theanine helps you to stay asleep. If you wake up during the night, taking L–theanine can help you get back to sleep.

Benefits of L-theanine

Improving sleep

With its ability to increase relaxation and lower stress, L-theanine can help in sleep in a number of ways. L-theanine may help people fall asleep more quickly and easily at bedtime, thanks to the relaxation boost it delivers. Research also shows L-theanine can improve the quality of sleep—not by acting as a sedative, but by lowering anxiety and promoting relaxation.

Reducing stress and anxiety

L-theanine is what’s known as an anxiolytic—it works to reduce anxiety. Some anxiolytics, such as valerian and hops, have sedative effects. L-theanine, on the other hand, promotes relaxation and stress reduction without sedating. L-theanine can help foster a state of calm, attentive wakefulness.

L-theanine has positive effects on both the mental and physical symptoms of stress, including lowering heart rate and blood pressure.

Research suggests that L-theanine can help reduce anxiety in people with schizophrenia and schizoaffective disorder.

Valerian Root

Valerian is an herb most commonly used for sleep disorders, especially the inability to sleep (insomnia). It is frequently combined with melatonin, lemon balm, or other herbs that also cause drowsiness. Valerian is also used for conditions connected to anxiety and psychological stress.

Valerian extract can cause sedation is by increasing your brain’s GABA level. GABA is an inhibitory neurotransmitter with a potential sedative effect. Unlike many prescription sleeping pills, valerian has fewer side effects and is a lot less likely to result in morning drowsiness

Passion Flower Extract

Passion flower (Passiflora incarnate) is a climbing shrub native to the tropical parts of the United States. Traditional herbalists enjoy a number of passion flower benefits, using it, for example, as a sleep aid, especially when patients complained of restlessness and interrupted sleep due to exhaustion. And recent clinical trials using passion flower show it is also one of the most valuable and effective herbal anxiety remedies in addition to its usefulness in improving sleep and treating insomnia.

Passion Flower appears to boost the level of gamma-aminobutyric acid (GABA) in your brain. This compound lowers brain activity, which may help you relax and sleep better.

Lemon Balm Extract

is a perennial plant from the mint family known for soft lemon scent. Its leaves are used as a soothing agent and may potentially aid sleep by:

  • Reducing stress. Lemon balm is reported to minimize stress by reducing symptoms of anxiety and minimizing agitation.
  • Reducing insomnia. Some data suggests that extracts of the leaf may minimize the effects of insomnia.
  • Calming the senses. Above all, lemon balm is considered by many to have a calming effect.

Several studies show that lemon balm combined with other calming herbs (such as valerian, hops, and chamomile) helps reduce anxiety and promote sleep.

Sleep Health Facts*

  • B vitamins helps tryptophan in your body convert to niacin and serotonin, which regulate sleep and increase REM. Consider foods rich in B3, B5, B6, B9 and B12 or a preferable supplement.
  • Vitamin D deficiency is associated with less sleep overall and also, with more disrupted sleep.
  • Studies have shown itamin E can help relieve hot flushes and night sweats for menopausal women, and improve sleep quality.
  • Magnesium is well known for its ability to relieve insomnia. One study found that it helps decrease cortisol, the “stress hormone” that can keep you up at night. It also helps muscles relax, to give you that calm “sleepy” feeling and help you unwind after a long day.

* Consult your physician before taking any supplements, minerals , amino acids or vitamins including but not limited to magnesium. In some cases , excess consumption of any of these can affect your health. For example, magnesium also has cardiac effects that may be undesirable in certain individuals.

Reviews for Serinytex®

  • I have tried several over the counter sleep aids and none compare to this one! I fall asleep within 30 minutes, stay asleep and wake up feeling great! Thank Dr. H for designing another home run product. No morning grogginess either.

    - M. Foster – March 22, 2018
  • So happy that I can finally sleep! I was tossing and turning throughout the night. Tried essential oils, music , hot baths . Even tried a few prescriptions but they gave me horrible side effects. Serinytex is just right. I feel refreshed in the am. If I have an early morning I just take though.

    - George. P – April 15, 2018
  • This is the best sleep aid I have tried. I am a life long insomniac and refuse to try any more prescription sleep aids. Some nights I take three but I wake up feeling like I got at least 6 hours of good sleep. Before 4 was a good night for me.

    - Brandy N. – April 20, 2018
  •  Serinytex makes me sleepy but not comatose. I have a 1 1/2 year old and am a single parent. If I need to wake up when he is crying I can and have no problem going back to sleep! Awesome product! I will keep taking this one. Worth every penny.

    - Tina k. – April 24, 2018
  • I am a shift worker and this stuff comes in handy regulating my sleep. It is smooth and i don’t feel medicated. Glad I found it.

    - Terrence O. – April 27, 2018
  • Took Alteril which worked only so so but I feel tired in the morning. Serinytex works good work me and my busy days. I like it and now have my son who is 18 starting it too. Great buy! Will recommend to others. 

    - Tony K. – April 28, 2018
  • When i saw the ingredients I was worried because I had tried melatonin and it didn’t do jack squat!! But my friend swore by it so i tried it and i guess the combo makes a difference. It helps me feels refreshed but I can’t say i sleep any ‘harder’ or ‘deeper.

    - Ulrick V. – May 1, 2018
  • My husband and I have been on Serinytex for two month and we love it! When we travel to different countries or times zones it really help beat that dreaded jet lag.
