Greens

Plants produce chlorophyll to absorb energy from sunlight. This chlorophyll is the main component of the various algae, sprouts, and leafy vegetables that we refer to as "greens".

Greens are available in tablets, capsules, loose powder, or as part of a multivitamin.

Well-known greens include chlorella, spirulina, wheatgrass, barley grass, and alfalfa.
