benefits of Spirulina are supported by recent research, and its
possibility for curing health issues is still being investigated.


You’ve likely heard of Spirulina if you’ve been keeping abreast of the

food source in several societies worldwide for hundreds of years.


Although it is usually well-tolerated, Spirulina is still regarded as a

Administration (FDA). It is pivotal to purchase from a reputable
brand. This article will discuss Spirulina’s beneficial properties
and side effects.

What is Spirulina?


Spirulina is a type of cyanobacterium, also known as blue-green algae. It is
produced in both fresh and saltwater. It is a production of
commercial safe human consumption products to be used in food and
supplements. This supplement can be used in the form of powder.
However, it is most normally prescribed as a tablet. It is
extensively used as a food source in some parts of Mexico and Africa
because it includes 60% protein and various vitamins and minerals.


Spirulina develops in lakes and can also grow in too harsh environments for
other organisms. Arthrospira platensis and Arthrospira maxima are the
two species’ sources of spirulina. The algae found on the pond’s
surface is the same as spirulina. Because spirulina is derived from
bacteria, it may be considered a protein powder source.


It’s also worth noting pseudo vitamin B12 is present as a vitamin source
of spirulina. However, it is other than the form that your body
absorbs typically. Furthermore, it is high in polyunsaturated fats,
C-phycocyanin, antioxidants, and beta carotene.


Several people take spirulina to assist others having allergies and asthma.
Many also believe that it will assist in the fight against
infections. However, few considered it a source of help in cancer
treatment. Some people use spirulina to support hyperglycemia or
diabetes. Someone else might use it to treat mouth ulcers. You can
also use it as a source of weight loss.


Nutritional value


Spirulina includes a wide range of vitamins, antioxidants, and minerals. All of
these are important for overall health. Spirulina contains the
following nutrients in 100 grams:


  • Calories:
  • Protein:
  • Carbohydrates:
  • Fats:


Spirulina has been shown to have a high protein level of about 60 – 65
percent. It is much higher than the vast bulk of vegetables. Protein
is an important trace element for reform and development. However,
numerous studies support the use of a high protein meal. On the other
hand, having spirulina regularly will guarantee that you are
ingesting a diverse variety of nutrients in huge volumes, which will
considerably benefit your health.


Benefits of Spirulina


Spirulina is a high-nutrient source. However, there have been a few studies
conducted on spirulina. According to research, this has
brain-protective antioxidant, anti-inflammatory, pain-relieving, and
antioxidant properties. Here are five health benefits of spirulina.



High in nutrients


Spirulina is a freshwater and saltwater growing organism. Cyanobacteria, like
plants, can generate the sun’s energy through a process known as
photosynthesis. Potassium, sodium, and vitamin A are the three
micronutrients discovered in the highest concentrations in spirulina.
It is also necessary for vision, the immune system, and reproduction.
An average everyday intake of spirulina is 1–3 grams. But doses as
high as 10 grams each day have been used successfully.


Relief allergic reactions


Many people suffer from allergies to dust, pollen, mites, pet dander, and
other substances. The pivotal active ingredient is known as
phycocyanin. For spirulina’s distinctive blue-green color, it plays
an important role. Phycocyanin has powerful antioxidant and
anti-inflammatory properties. However, it can attack free radicals
and prevent the formation of inflammatory signaling molecules.

Health of heart


It has been proposed that Spirulina
can benefit the heart by decreasing the quantity of bad cholesterol
and blood pressure. Scientists have found that phycocyanin has
antihypertensive properties, i.e. it reduces blood pressure. However,
it is a pigment found in Spirulina. Spirulina can also aid in the
reduction of levels of cholesterol and the avoidance of


In a 2010 research published in The International of Nutritional Science
and Vitaminology, rabbits were fed a cholesterol diet. It contains
0.5 percent cholesterol that is provided for four weeks. Another
study found that 1 gram of Spirulina daily limited triglycerides by
16.3 percent. Whereas bad levels by 10.1 percent in individuals with
high cholesterol. On the other hand, Spirulina raises oxidative
stress in your body, which benefits your cardiovascular system.


Protect from cancer


Several of the antioxidants found in spirulina have anti-inflammatory
qualities in the body. Cancer and other maladies are exacerbated by
inflammatory disease. When evaluated on human cells in the pancreas,
the researchers discovered that innovative therapeutic approaches
substantially lowered the growth and metastasis of pancreatic cancer
cell lines in vitro in a daily dosage way compared with uninfected
cells. Essentially, it demonstrated that including spirulina in one’s
foods can help protect the development of various cancers.


Lower blood sugar level


A few animal kinds of research showed that ingesting spirulina can
decrease blood sugar. In reality, findings demonstrate that it can
surpass several of the most frequently used prescription medications,
such as Metformin.


There seems to be some indication that spirulina can assist patients.
However, 2 grams of spirulina each day resulted in a remarkable
decrease in sugar levels. It is done in two-month research of 25
patients with type 2 diabetes.


According to studies, a 1% decrease in this indicator can minimize the chances
of diabetes-related death by 21%. Moreover, this was a slight and
brief study. More research is required.

Side effects of Spirulina


Even though spirulina is typically assumed to be safe, it would have some
adverse effects and disadvantages, particularly for individuals with
pre-existing conditions. Whereas serious kind of side effects from
spirulina are uncommon. They can appear and cause severe effects.
Here are a few of the possible side effects and disadvantages of



Spirulina absorbs what is in the water around it. In a relatively similar way
that plants absorb nutrients from the soil. If spirulina develops in
water contaminated with heavy metals, these contaminants may also be
observable in the supplements. Certain spirulina species grown in
uncontrolled conditions are frequently contaminated with metals such
as mercury, lead, arsenic, and cadmium.


Long-lasting ingestion of spirulina from untrustworthy sources causes harm to your
significant organs. These are the liver and pancreas. Check to see
how far your spirulina is coming from.

May affect blood clotting


Spirulina has a therapeutic index, which means it can thin your blood and
lengthen the time it would take for it to clot. When you’ve been
hurt, blood clotting is essential, and it can avoid excessive
bruising and bleeding. On the other hand, Spirulina supplements may
intrude with or slow down the progress. Thus, you should still
explain this hazard to your health professional and implement their
medical advice when it comes to supplements.


Phenylketonuria is a hereditary condition in which the patient cannot metabolize the
amino acid due to a lack of an enzyme known as phenylalanine
hydroxylase. Because spirulina contains phenylalanine, people with
the disease should prevent it.


The patient has stalled development, muscle spasms, hyperactivity, and an
analytical disability. Regretfully, phenylalanine is abundant in
spirulina. Spirulina ingestion worsens the signs of phenylketonuria.


Tips to avoid side effects


Because spirulina may have disadvantages or side effects for some people, you
should consult with a doctor before incorporating it into your diet
or supplement regimen. To avoid spirulina being polluted with toxins,
only buy products from reputable companies that have been evaluated
by third-party organizations such as USP or NSF International.
Remember that nutritional supplements are totally unregulated in the
United States, and even certified may not be entirely free from

Bottom Line


It should have been mentioned that some spirulina consumers have
disclosed a small series of adverse side effects such as pains,
nausea, headaches, allergic reactions, and sleeplessness. Whereas
more study on spirulina is wanted to verify the impacts of
supplementing it on health. There do seem to be a considerable amount
of benefits linked with

But while spirulina is exceptionally beneficial to our bodies, the
correct dose is essential. To get the most out of this fantastic
