Alcohol-free, sugar-free, vegan, and non-GMO, this tincture uses glycerin to reduce bitterness for a smooth taste. German technology powers a simple three-ingredient formula (water, glycerin, schisandra) with up to 98% absorption. Shake well and use a few drops in your beverage or directly under the tongue.
