Enjoy this offer to Attain Tinctures Begin from $38. Tinctures are an extract of functional mushrooms that are dissolved in alcohol. The amount of material to liquid used is the ratio that indicates the concentration strength of the tincture. The alcohol in the tincture helps increase the absorption rate of the functional mushrooms and makes tinctures the quickest way to feel the benefits. Beta-glucans are the active ingredients that make the tincture so powerful.
