What is Chlorella Blue-Green Algae Powder?
Chlorella (Chlorella Vulgaris) algae are one of the oldest foods on the planet and date back to the
Precambrian period. Chlorella algae is a fine blue-green color due to its high levels of chlorophyll. Its
cells are also quite small, equivalent to that of a human blood cell. The name Chlorella reflects these
features, as it comes from the Greek word chloros, meaning green, and the Latin word ella, meaning small.
Scientists discovered the unicellular freshwater alga in 1890, but they didn’t uncover its nutritional
properties until the 1990s. However, scientists have researched the Chlorella genus of algae for its
nutritive properties since the 1940s. Populations around the world boomed following World War II, and the
agriculture industry couldn’t keep pace with the demand. Even if countries expanded their farmlands, many
would still fall significantly short of their populous’ needs. Countries experienced protein shortages as
well, as cultivating livestock was an expensive process.
Chlorella algae rose to prominence as a potential solution to these issues, as it is rich in
protein, fats, and vitamins. However, interest in Chlorella waned due to advances in agriculture
and crop efficiency resolving the world food shortages. Even so, it remains a non-meat option for protein
and many other nutrients. The Chlorella Vulgaris species is a bioavailable source of vitamin B12,
iron, and protein.
What Makes Chlorella Algae Powder so Popular?
Like Spirulina Algae, chlorella alga is a single-celled
primitive organism. Chlorella vulgaris is one of the more popular Chlorella species for
producing supplements, as it can survive in unfavorable conditions and resist foreign invaders. Chlorella
learned how to adapt to fresh water and survive the occasional drying of ponds. It developed an outer
fibrous shell surrounding a delicate, nutrient-rich inner cytoplasm.
This fibrous shell has two major functions. The first is that it protects inner cellular membranes until the
alga is completely desiccated. Yet chlorella has a more important trick to beat the competition: the outer
fibrous shell grabs and holds nutrients from the water before the pond completely dries. By doing so,
chlorella can survive and flourish once the pond refills. It is this affinity for absorbing and retaining
minerals and other nutrients within chlorella's outer shell that makes it a valuable supplement.
What Does "Broken Cell" Mean?
Chlorella: A Vegan Superfood
Chlorella is a popular supplement among vegans. It’s a non-animal-based protein source, and it’s rich in
vitamin B12. Vegans often struggle to consume this essential vitamin, as most B12 food sources come from
animal meat and dairy products.
Chlorella Nutrition Information
A one ounce serving of chlorella provides the following:
- Calories: 115
- Protein: 16g
- Carbs: 7g
- Fat: 3g
- Vitamin A: 287% daily value (DV)
- Thiamine (B1): 32% DV
- Riboflavin (B2): 71% DV
- Methylcobalamin (B12): 330% DV
- Iron: 202% DV
- Magnesium: 22% DV
- Phosphorous: 25% DV
- Zinc: 133% DV
Each chlorella microorganism contains a nucleus, starch grains, chloroplasts, and mitochondria surrounded by
a cell wall made primarily of cellulose. The outer shell is indigestible. PureBulk Chlorella is referred to
as "broken cell wall algae." High-pressure nozzles break through the outer shell to expose the nutrient-rich
cytoplasm inside. It also exposes more of the fibrous outer shell surface area, enhancing the digestibility
of this single-celled, nutritionally packed microalgae.
Potential Chlorella Benefits
Vegan Complete Protein
Chlorella is a complete protein, as it contains all nine essential amino acids: histidine, isoleucine,
leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. It also contains several
non-essential amino acids: alanine, arginine, aspartic acid, cysteine, glutamic acid, glycine, proline,
serine, and tyrosine.
Rich in Several Nutrients
It’s rich in vitamins and minerals, including chlorophyll, vitamin A, vitamin B12, iodine, vitamin K1, and
Iron. Chlorella contains small amounts of several other important nutrients: riboflavin (vitamin B2),
manganese, vitamin C (ascorbic acid), biotin (vitamin B7), vitamin B6, thiamin (vitamin B1), phosphorus,
vitamin E, magnesium, pantothenic acid (vitamin B5), potassium, and zinc. Like other algae, chlorella is a
great source of omega-3 fatty acids. It also contains numerous antioxidants.
Binds to Heavy Metals
Chlorella may enhance how the body clears toxins from the body. It absorbs significant levels of heavy metals
from its surrounding environment, and it may act as a detoxifying sponge as it passes through the digestive
tract. It’s also able to weaken the toxicity of heavy metals and reduce levels of other damaging food
Immune System Enhancer
Animal and human studies have shown that chlorella boosts the body’s natural immune response, which may
improve overall immunity. One study noted that men taking chlorella produced more antibodies than those
taking a placebo. Another study noted that chlorella increased participants’ immune activity.
Chlorella is rich in antioxidants that help fight free radicals and oxidative stress. Over time free radical
damage can lead to, contribute to, or worsen many chronic illnesses. Some of its more notable antioxidants
include beta-carotene, chlorophyll, vitamin C, lutein, and lycopene. One study noted that chlorella exerts
bioprotective effects in young individuals and bioremediation in older participants. It also boosts
antioxidant levels in individuals with an increased risk of oxidative damage. It may convey neuroprotective
effects by reducing inflammation in the brain.
Chlorella: A Complete Vegetarian Protein
Vegetarians and vegans have to consume a mix of plant-based proteins, as many plant foods lack certain amino
acids. Chlorella has all nine essential amino acids and is a high-protein food.
Preliminary research shows chlorella may improve aerobic endurance. Participants taking chlorella supplements
showed improved oxygen saturation in their lungs after four weeks, whereas the placebo group experienced no
improvements. Researchers hypothesized that this is due to chlorella’s branched-chain amino acid content,
isoleucine, leucine, and valine. Multiple studies have shown that BCAAs are effective aerobic endurance
enhancers. Chlorella is also a good protein source, which is essential for muscle growth, development, and
Are There Nutritional Differences Between Chlorella Algae and Spirulina Algae?
Chlorella has higher levels of provitamin A, iron, magnesium, omega-3 fatty acids, riboflavin (vitamin B2),
and zinc when compared to spirulina.>a Spirulina
has fewer calories per serving and has more copper and thiamine (vitamin B1) than chlorella. While lower
than chlorella, spirulina has notable levels of vitamin B2 and iron. Both are rich in antioxidants and
nutrients. However, chlorella has a slight nutritional advantage, whereas spirulina has a marginally higher
Does Chlorella Powder Taste a lot Like Spirulina Powder?
Spirulina has a slight fishy or ocean taste because manufacturers typically cultivate it in salt or brackish
water. Chlorella is a freshwater alga and is very "green" tasting owing to its high chlorophyll content,
like barley green powder or wheat grass juice powder. For most people, the aroma and taste of chlorella
algae powder are neither unpleasant nor objectionable. If you prefer, PureBulk offers vegetarian and gelatin
Potential Side Effects of Chlorella Blue-Green Algae
Most individuals can take chlorella supplements without experiencing adverse effects. Some individuals may
experience an upset stomach or nausea. Individuals may notice a harmless green coloration of their bowel
movements due to chlorella’s chlorophyll content. Excess doses can cause diarrhea. Individuals with
autoimmune conditions shouldn’t take chlorella powder without consulting their physician first, as it can
affect the immune system. Chlorella may interact with some blood thinners as well. Some individuals may
experience allergic reactions to chlorella, particularly those with an iodine allergy. Always speak with a
doctor before starting any new supplements.
Bioavailability, Mixing, and Solubility of Chlorella Blue-Green Algae
Chlorella blue-green algae powder mixes well with water or juice. Strong-flavored vegetable or citrus juices
mask any taste chlorella may have.
