Source Naturals - Kava 500 mg - 60 Tablets Source Naturals Kava can help with occasional anxiety. Source Naturals Kava is made from the roots of a pepper family plant, Piper methysticum. Pacific Island people from New Guinea to Hawaii have used kava for centuries. Research has shown kava extracts contain pharmacologically active constituents known as kavalactones, which are thought to be responsible for a relaxed and calm state of mind. Leaders of the Wellness RevolutionSource Naturals was created in 1982 by C.E.O Ira Goldberg to support each individual's potential to enjoy optimal health. At that time, the kind of nutritional formulations he envisioned - for the maintenance of well-being and the enhancement of life - simply didn't exist. The idea of combining many nutrients, herbs and nutraceuticals in one formulation, though common today, was then a rarity. Source Naturals pioneered the concept with Wellness Formula, now the industry's #1 immune support product. Source Naturals subsequently introduced numerous award-winning formulas, recognized for their excellence in independent surveys and nutritional analyses. In addition to Wellness, these award-winners include Life Force Multiple, Mega-Kid Multiple, Inflama-Rest, the Skin Eternal line, Higher Mind, Essential Enzymes, Male Response, and more. Source Naturals' comprehensive Bio-Aligned Formulas help bring the power of alignment to your body. When formulating, Source Naturals evaluates the underlying causes of system imbalances, and then provides targeted nutrition to interdependent body systems. Source Naturals' line of more than 600 products also includes well-researched, single entity nutrients in their highest quality and most bioavailable forms. Source Naturals nutritional supplements are at the leading edge of today's Wellness Revolution.
