What is Spirulina?
Spirulina is a natural algae (cyanobacterium) that is incredibly rich in protein and provides a good source of antioxidant and other nutrients. It has been the top selling food for many many years since it can provide a ton of benefits in a small dosage. It is largely comprised of essential amino acids, iron and protein. It is often described as the most powerful food on earth. Being high in protein content and other nutrients it is often recommended to use this powder anytime the immune system needs a boost.
However, it is worth to note that Spirulina does not contain Vitamin B12. It predominantly contains pseudovitamin B12 which is biologically inactive in humans.
If you are still not convince let me describe you the top benefits of Spirulina.
Top benefits of Spirulina
1. Most powerful food on earth
The rich concentration of protein and other nutrients in the powder has given Spirulina to be classified as the most powerful food on earth.
To understand this it is essential to understand it’s nutritional value per 100g.
Protein: More than 55% of Spirulina is a high quality natural protein often compared to eggs. If you are a vegetarian like me deprived of eating eggs this is a strong reason to accommodate Spirulina in your supplement list.
Iron: Spirulina is one of the best plant source of iron which makes it the favorite food item among vegetarians and vegans.
Vitamins: Spirulina is a rich source of vitamins such as Vitamin A, B1, B2, B5, B6, E and K.
2. Powerful Detox
Spirulina helps in the removal of heavy metals from the body. One study shows that 250mg of Spirulina extract combined with 2mg of zinc twice a day reduced the arsenic toxicity by 47%!  It is extremely high in chlorophyll which helps fight cancer, improving liver detoxification, speeding up wound healing, improving digestion and weight control, and protecting skin health.
3. Balances Blood Sugar Levels
Spirulina is effective in controlling the blood glucose levels and in improving the lipid profile of subjects with type 2 diabetes mellitus 
4. Improves HIV
Up until recently researchers were puzzled as to why people living in Japan, Korea, and Chad have low HIV / AIDS rates. Possible explanation to this is the people living in these regions consume algae regularly in their food!
Research was done on 11 HIV patients. People were divided into 3 groups: one that was assigned 5g of brown seaweed (Undaria pinnatifida), one that was assigned 5g of Spirulina (Arthrospira platensis) and one that was assigned a combination of both. No adverse effects were observed for the 11 subjects in the phase I trial, and quality of life indicators improved at 3 weeks. CD4 cells (milliliters) and HIV-1 viral load remained stable over the first 3-month study period. The trial was extremely promising to the level that one subject continued in the study for 13 months and had clinically significant improvement in CD4 and decreased HIV viral load! 
5. Allergies and Sinus
Spirulina helps reduce allergies as well as sinus issues. It can reduce inflammation that leads to nasal congestion and other issues such as itching and sneezing.
6. Anti Cancer
A study of 2014 reveals that Spirulina may be very helpful in cancer especially pancreatic cancer 
More than 100 articles have been published evaluating Spirulin’s effect on cancer cells 
7. Wake up call
Spirulina provides abundance of energy. Therefore it is best to take Spirulina in the morning when we need a wake up call!
8. Keeps eyes healthy
Spirulina is an excellent supplement to keep eyes healthy. Vitamin A is helpful in improving eyesight and this blue green algae is rich in Vitamin A. Since long time carrots have been prescribed for those who have weak eyesight but if we compare gram per gram of Spirulina and carrot – this powder has 10 times the Vitamin A contained in carrot.
Are there any side effects?
Blue green algae that is free from contaminants are very safe to consume. However, please bear in mind that contaminated blue green algae can cause
- Liver damage
- Stomach pain
- Rapid heartbeat
Therefore it is very important to verify the quality of the Spirulina that you intake.
Where to buy?
You can purchase Spirulina in powder form or tablets / capsules however it is preferable to buy the capsule form of it because the eating the powder form is a difficult job due to the taste! I have found the following products are real authentic if you wish to buy:
