Unlike many food supplements, chlorella has one unique feature that makes the manufacturing process one of the primary concerns when considering a source of supplementation. Chlorella is completely indigestible by humans. We simply do not have the enzymes to break down its cell wall.

Unlike other green foods, chewing and digesting chlorella will not release the powerful health benefits contained within this green algae. This is because chlorella's tough outer cell wall, which is also chemically responsible for binding with the toxins inside your body, cannot be broken down by your biology, Therefore, it is imperative that the manufacturing process break down the tough outer cell wall for you, as this is the only way to make the chlorella biologically available to remove toxins from your body.

Heaven’s Choice is an Organic Broken Cell Wall chlorella cultivated indoors, keeping out any potential outdoor contamination. Furthermore, chlorella that is cultivated outdoors develops a thick cell wall to protect itself from the elements, which is virtually impossible for the human digestive system to break down. To combat this problem, manufacturers of outdoor-grown chlorella typically pulverize or mechanically rupture the cell wall to unlock vital nutrients. Heaven’s Choice Chlorella, grown indoors, does not need the thick cell wall and instead develops a very thin wall that breaks naturally during processing. Since Heaven’s Choice Chlorella does not undergo a forceful process of cell wall rupturing, the vital nutrients found inside remain intact and highly bioavailable for optimal nutrient absorption.
