Education: Kava & AlphaWave® L-Theanine

KAVA

Botanical and Cultural Origin Kava (Piper methysticum) is a perennial shrub native to the South Pacific. Traditionally prepared as a cold-water infusion from the peeled and ground rootstock, it has over 3,000 years of documented ceremonial and therapeutic use. Kava has played a central role in Pacific Island cultures, highly valued for its ability to enhance social connection and promote both physical and mental relaxation. This longstanding traditional use forms the foundation for its inclusion in modern clinical practice.

Material Selection and Extraction The kava extract featured in this product is derived exclusively from the fresh rhizome of the Noble variety of P. methysticum—the only kava type traditionally and consistently consumed in Pacific Island cultures. Cultivars such as Borogu, Eva, and Namabawan are favoured for their balanced chemotypes, desirable sensory profiles, and lower concentrations of undesirable constituents.

To ensure quality and safety, this extract is:

• Standardised to ≥10% total kavalactones: The key lipophilic compounds responsible for kava’s clinical effects.

• Prepared using traditional water extraction: This avoids organic solvent residues and preserves the full spectrum of native kavalactones.

• Sourced exclusively from the rhizome: Stem peelings and aerial parts are strictly excluded to reduce levels of Flavokawain B (FKB)—a chalcone compound associated with hepatotoxicity when co-administered with paracetamol.

This careful sourcing and processing approach supports a clinically responsible kava profile, perfectly aligned with both traditional preparation methods and contemporary safety considerations.

Neurophysiological Pathways The central nervous system activity of kava is attributed to its kavalactones, which modulate multiple neurochemical targets. These include:

• Interaction with the GABAergic pathway.

• Modulation of voltage-gated ion channels.

• Influence on monoamine neurotransmission.

• Effects on noradrenaline transport.

ALPHAWAVE® L-THEANINE

AlphaWave® is a high-purity, clinically studied form of L-theanine, produced via a proprietary fermentation and purification process and standardised to ≥98% purity. It offers a concentrated and consistent source of this neuroactive amino acid, known for promoting a state of calm without causing sedation.

Mechanisms of Action L-theanine is a non-proteinogenic amino acid that modulates several neurophysiological pathways involved in the stress response and mental relaxation:

• GABAergic modulation: L-theanine has been shown to increase GABA levels and support GABA-A receptor expression, enhancing inhibitory neurotransmission without causing sedation.

• Glutamatergic regulation: It modulates the glutamatergic system by attenuating glutamate-induced excitotoxicity and supporting a healthy excitatory-inhibitory balance.

• Alpha brainwave activity: L-theanine increases alpha brainwave activity, particularly in the frontal cortex (as measured via EEG). This brainwave pattern is associated with a state of "relaxed wakefulness," typically observed when an individual is calm yet alert, such as during meditation.

Clinical Benefits These underlying mechanisms support L-theanine’s observed clinical benefits, including its ability to calm the mind and reduce the physiological response to stress without cognitive impairment. AlphaWave® L-theanine has been evaluated in multiple clinical studies demonstrating its efficacy in supporting a healthy stress response. Its evidence base supports both acute and ongoing use in stress-related presentations, reinforcing its role as a non-sedating, well-tolerated compound.
