60 Caps

Efectiv Zylaria 60 Caps, 500mg Xylaria Nigripes Extract for Natural Sleep Support

Efectiv Nutrition Zylaria is a non-stimulant sleep support supplement built around the trademarked Zylaria extract. Each capsule delivers 500mg Zylaria (Xylaria nigripes extract). The 60-capsule bottle provides 60 single-capsule servings.

Zylaria is a standardised extract of Xylaria nigripes, a medicinal fungus used in traditional Chinese medicine. Research suggests Zylaria supports GABA production and activity in the brain. GABA (gamma-aminobutyric acid) is the primary inhibitory neurotransmitter in the CNS, responsible for reducing neuronal excitability and creating the conditions for onset and maintenance of sleep. Unlike supplemental GABA itself, which has limited blood-brain barrier permeability, Zylaria is proposed to support endogenous GABA synthesis via GAD enzyme support, potentially achieving more effective CNS delivery. The 500mg dose is the clinically studied amount.

What separates Zylaria from common sleep aids like magnesium or melatonin is the mechanism specificity. Magnesium supports sleep through muscle relaxation and general nervous system calming. Melatonin directly modulates the circadian rhythm. Zylaria specifically targets GABAergic inhibitory tone, addressing the hyperarousal and cognitive overactivation that prevents sleep onset in high-stress individuals - a different and complementary pathway.

Zylaria suits athletes with overthinking or cortisol-driven sleep onset problems, anyone who cannot tolerate pharmaceutical sleep aids or melatonin, and individuals who find that mental stimulation or training-induced nervous system activation disrupts sleep quality. It is not suitable for use alongside benzodiazepines or other GABA-modulating medications without medical advice. Contains no major allergens.

Frequently Asked Questions

How do I take Efectiv Zylaria?

Take one capsule with water 30 to 60 minutes before bed. After the first week of consistent use, you can increase to two capsules per night if you prefer a stronger dose. Zylaria can be used nightly as part of an evening routine.

How is Zylaria different from Efectiv Sleep Formula Powder?

Zylaria is a single-ingredient capsule delivering 500mg of Xylaria nigripes extract for natural GABA support. Sleep Formula Powder is a multi-ingredient drink combining glycine, magnesium, lemon balm, valerian and other actives. Zylaria suits a simpler nightly capsule routine; the powder suits broader stack coverage in one serving.

Can I take Zylaria with magnesium or ashwagandha?

Yes. Zylaria pairs well with Efectiv Magnesium Bisglycinate, which supports muscle relaxation through a different pathway, and with Efectiv Ashwagandha KSM-66 if elevated stress is contributing to broken sleep. Avoid combining Zylaria with a second dedicated sleep product such as Sleep Formula Powder, as that up on the same goal.
