Lavela WS 1265, also known as Silexan™, is a clinically studied, non-habit-forming oral lavender essential oil (Lavendula angustifolia) that has been shown to promote relaxation, foster sleep quality in those experiencing occasional anxiety, calm nervousness, and support general mental health.* Clinical trials published in peer reviewed medical journals demonstrate Lavela 1265 as a well-tolerated option for occasional anxiety.*1,2

How it works

While lavender's chemical composition includes terpenes, alcohols, ketones, polyphenols, and flavonoids, its monoterpenes linalyl acetate and linalool are the most likely primary components responsible for its beneficial activity.3 Both linalool and lavender essential oil have demonstrated in vitro a dose-dependent ability to interact with the glutamate NMDA-receptor and an ability to bind to the serotonin transporter (SERT).4 The lipophilic properties of lavender essential oil enable it to cross cell membranes and impact signaling channels in neurons isolated from animal models.5

Clinically researched Silexan

Lavela WS 1265 (Silexan) is one of the few oral lavender essential oils with demonstrated efficacy and safety in published, controlled clinical trials. Use of the studied material has been proven to provide a statistically significant reduction of nervousness compared to placebo by four weeks.*1,6 Lavela WS 1265 supports sleep when disrupted by occasional anxiety and helps relieve occasional anxiety without sedation, withdrawal, or unwanted sedative effects.*
