Chlorella is one of the most ancient food plants on earth. These tiny, single-celled green micro algae are “fresh-water phytoplankton” that float on the water’s surface soaking up sunshine and converting it into green energy power cells! Prairie Naturals Chlorella comes in two dosage forms of broken-cell-wall chlorella: powder and tablets. The powder is ideal for adding to smoothies and shakes for instant appetite control. The tablets are convenient and easy to use. No fillers, binders, excipients, carriers. Just pure, organic and fair trade chlorella.
