Functional mushrooms have been sought after for centuries due to their rich contents of key nutrients, such as vitamins, minerals, and amino acids (1). Not only do these fungi contain beneficial macronutrients, they also may help support a vital function for healthy living: sleep.

Zylaria™, or Xylaria nigripes, is a type of mushroom that was first used medicinally centuries ago in Traditional Chinese Medicine (TCM) practices. Like many mushrooms, it grows underground, about a foot down, in dark, damp and warm conditions but unusually, only where there’s also a termite nest, specifically, the nest of the Odontotermesformosanus termite.

Both fungus and termite have a happy, beneficial relationship with each other, the fungus thriving in the folds of the termite nest, the termite using the fungus as its primary source of nutrients.

Zylaria™ is a rich source of amino acids, and not just for termites, but for us humans too. And the most exciting amino acid in this medical mushroom is gamma-aminobutyric acid or GABA.

GABA is a neurotransmitter, a chemical that acts as a messenger between the brain and the nervous system, taking messages from the brain to the nerve cells to slow down their activity. In other words, it’s a way of saying it’s the brake pedal for our continuous on-the-go minds. Its role is to counteract the compounds that exhibit ‘excitement’ in our brain, helping the human body to unwind, relax, and feel at ease.

Zylaria™ as a Natural Sleep Aid

Many people experience challenges in falling asleep and/or maintaining sleep.

Over time may lead to mental distress, bad memory, or mood disorders. It’s for this reason that GABA supplements and foods containing GABA are the focus of research by scientists looking into stress and poor sleep and why we at Nuliv Science focus on this area of research. GABA-promoting Zylaria™ also contains glutamic acid and glutamate decarboxylase, which both have natural, and importantly, gentle, tranquilizing effects.

Xylaria nigripes supplements have been displayed to help reset the natural body clock of the body, allowing sleep patterns to improve leading to more restorative and peaceful sleep, taking less time to fall asleep and staying asleep for longer.

And what’s more, the sleepy nutrients in Zylaria™ don’t act like a sleeping ingredient by completely ‘knocking out’ the end-users so that they fall asleep. Instead, the key nutrients naturally work in tandem with the brain to send more relaxing messages, promoting a general sense of calm. This means that taking Zylaria™ as a supplement to promote restful sleep may not exhibit side effects like ‘brain fog’ and grogginess that some natural sleeping aids do.

Zylaria™ Also Helps Lift Mood

Researchers have found that the benefits of Zylaria™ also may help those that are feeling down.

Researchers have found that in general, people with mood complications tend to have lower levels of GABA. Therefore, topping up levels of GABA with GABA-rich supplements and foods such as Zylaria™ seems to have positive benefits.

Research on Xylaria nigripes

Xylaria nigripes (Zylaria™) used in traditional Chinese medicine attempts to resolve sleep, mood, and memory problems (1). Pharmacological studies (2) indicate that the amount of glutamic acid (Glu), γ-aminobutyric acid (GABA), and the ability to bind to GABA receptors in the brain was higher in subjects in the treatment group compared to subjects in the control group after the administration of Zylaria™.

Furthermore, the activity of glutamate decarboxylase (GAD) was also elevated. This suggests that Zylaria™ may possess the ability to facilitate the entry of Glu and GABA into the brain to activate the receptors of GABA and thus exert its sedative and sleep-promoting and mood-elevating properties.

Market Potential

Much opportunity abounds for brands to include Zylaria™ in their formulas. Key players in the nutraceuticals industry can take advantage of the continuously growing demand that consumers are influencing with their purchases, specifically as it relates to sleep quality, mood, and general wellness.

Busy lifestyles, long days at work, and the demands of the workplace, and mood all play a role in affecting sleep quality and the brain’s general functions over the course of time.
