The majority of the spices in MetaBuz™ come from the bark, roots, and seeds of plants and trees. As such they are are not chemically altered or extracted- they are simply ground into small fibers or particles. They will not dissolve but merely remain in suspension. After time that will settle out to form a clump in the bottom and this may not taste pleasant.
To minimise settling out at the bottom, stir or shake as you drink. If you are drinking cold chai tea the addition of a few drops of lemon juice can reduce the sensation of fibers and clumping.
