Certified Organic Kava Kava Dried Root Extract

Also known as: Kava, Kava Kava, *Piper methysticum*

Overview

Kava is an herbal supplement derived from the root of *Piper methysticum*, native to the South Pacific. Traditionally consumed as a tea or in capsule form, kava is primarily utilized for its anxiolytic properties. The active compounds, kavalactones, play a significant role in the modulation of the gamma-aminobutyric acid (GABA) pathway, which is associated with feelings of calmness and relaxation. While research into kava is of moderate maturity, it presents a mix of positive findings regarding its efficacy in reducing anxiety, insomnia, and certain menopausal symptoms, although safety concerns, particularly regarding liver health, have been noted. Kava can be found in various forms including extracts and capsules, which differ in their concentrations and extraction methods, influencing absorption and effectiveness.

Benefits

Kava extract is primarily noted for its effectiveness in reducing anxiety symptoms, with several studies, including a 2003 Cochrane review, demonstrating statistically significant reductions compared to placebo. Individuals experiencing moderate to severe anxiety may find kava particularly beneficial, with many users reporting noticeable improvements within weeks of continued use. Some secondary benefits include improved sleep quality and alleviation of menopausal symptoms, though these effects are less comprehensively supported. The variability in effect sizes across studies underlines that while kava may significantly help anxiety relief for some, results can vary based on individual factors and preparation methods.

How it works

Kava operates primarily through the modulation of the GABA pathway, influencing inhibitory neurotransmission. It interacts with GABA_A receptors and affects related neural circuits, thereby impacting the central nervous system. Additionally, kavalactones have been shown to engage with various receptors, including opioid, dopamine, and histamine receptors, highlighting its complex influence on mood and stress response. The overall absorption and bioavailability of kava can be affected by the form in which it is consumed, as well as individual differences in metabolism.

Side effects

While kava is generally well-tolerated, it can lead to common side effects such as fatigue, headaches, and gastrointestinal distress. Less commonly, dermatological reactions and neurological symptoms may occur. Severe liver toxicity is a rare risk, often associated with specific kava preparations and not with standard doses; however, caution is advised as some preparations can induce liver injuries. Individuals taking medications metabolized by the liver, pregnant or breastfeeding, or with underlying liver conditions should avoid kava. There is a noted risk for individuals with a history of substance abuse or those on potential interacting medications, necessitating careful monitoring for adverse reactions.

Dosage

The minimum effective dose of kava is generally around 100 mg of standardized extract per day, while the optimal dosage range is typically between 100-300 mg daily, divided into multiple doses to enhance effectiveness and minimize side effects. Due to the lack of definitive data on a maximum safe dosage, caution is advised for dosages exceeding 300 mg. For best results and to mitigate gastrointestinal issues, kava should ideally be consumed with meals. Different extraction methods can affect the efficacy of kava, with lipid-soluble extracts often being more potent than aqueous extracts, emphasizing the importance of preparation in the overall absorbability and effectiveness of kava.
