In today’s fast-paced world, superfoods like spirulina, wheatgrass, and acai berries have taken center stage. But there’s one nutrient-dense green alga that’s creating quite the buzz in the world of natural health—Chlorella. Touted for its detoxifying properties, impressive nutritional profile, and potential to boost overall wellness, chlorella is increasingly finding a place in people’s daily routines. If you’re curious about this vibrant green supplement, this blog post will walk you through everything you need to know—its nutritional facts, benefits, side effects, how to take it, and more.
What is Chlorella?
Chlorella is a single-celled, freshwater green alga that has been around for over 2 billion years. Native to Japan and Taiwan, it is known for its rich green pigment, its high chlorophyll content. There are over 30 different species of chlorella, but Chlorella vulgaris and Chlorella pyrenoidosa are the two most commonly used in dietary supplements.
Despite its tiny size, chlorella packs a serious punch in terms of nutrients. However, its cell wall is too tough for humans to digest, which is why supplements often come in “cracked cell wall” or “broken cell wall” forms to ensure bioavailability.
