Safety and Side Effects of Spirulina Consumption
Spirulina is a type of blue-green algae that has been consumed for centuries for its nutritional and health benefits. It is a good source of protein, vitamins, minerals, and antioxidants. Spirulina is also a relatively easy organism to grow, making it a sustainable and cost-effective source of these nutrients.
Safety
Spirulina is generally considered safe for consumption by most people. However, there are some potential side effects and interactions with medications that should be considered.
Side Effects
Some people may experience mild side effects after consuming spirulina, such as:
Stomach upset
Headache
Dizziness
Allergic reaction
In rare cases, more serious side effects have been reported, such as:
Liver damage
Kidney damage
Blood clotting problems
Medication Interactions
Spirulina may interact with certain medications, such as:
Blood thinners
Diabetes medications
Immunosuppressants
Antidepressants
If you are taking any medications, it is important to talk to your doctor before taking spirulina.
Importance of Sourcing Spirulina from Reputable Manufacturers
It is important to source spirulina from reputable manufacturers that use safe and sustainable cultivation practices. Spirulina that is grown in contaminated water or that is not properly processed may contain harmful bacteria or toxins.
Specific Populations
Pregnant women and breastfeeding mothers: There is limited information on the safety of spirulina consumption for pregnant women and breastfeeding mothers. It is best to consult with your doctor before taking spirulina if you are pregnant or breastfeeding.
Children: Spirulina is generally considered safe for children to consume. However, it is important to start with a small dose and increase gradually to see how your child tolerates it.
People with allergies: Spirulina can cause allergic reactions in some people. If you have any allergies, it is important to talk to your doctor before taking spirulina.
Conclusion
Spirulina is considered by many medical doctors, scientists, and nutrition experts to be the world’s most powerful superfood. It is gaining more attention from medical scientists as a nutraceutical and source of potential pharmaceuticals. There are several new noble reviewed scientific studies about the spirulina’s ability to hinder viral replication, strengthen both the cellular and humoral arms of the immune system and cause regression and inhibition of cancers. While these studies are preliminary and more research is needed, the results so far are exciting.

It took modern man 50 years of research to rediscover and reveal spirulina as the most nutritious food on the planet. Millions of people worldwide eat spirulina cultivated in scientifically designed algae farms. Current world production of spirulina for human consumption is more than 1,000 metric tons annually. The United States leads world production followed by Thailand, India and China. Aztec Foodgrowers Corp. is the pioneer Filipino producer of spirulina here in the Philippines. More countries are planning production as they realize it is a valuable strategic resource.

Spirulina is not chlorella, or the blue-green algae harvested from Klamath Lake, Oregon. Chlorella, a green micro- algae, is a nutritious food but does not have the same anti-viral, anti-cancer and immune stimulating properties of spirulina. The chlorella cell wall is made of indigestible cellulose, just like green grass, while the cell wall of spirulina is made of complexed proteins and sugars.

Today Spirulina is being used as a therapeutic agent because of its antioxidant, anticancer properties and its ability to strengthen the immune system. Spirulina has properties known to lower blood sugar levels in diabetics, have beneficial effects on patients suffering from pancreatitis, hepatitis and cirrhosis. Helpful in glaucoma, cataracts and night blindness. It has high contents of essential fatty acids, thus making it an effective ingredient for heart and liver protection.

Scientific studies also have indicated that Spirulina has got anti-inflammatory, anti-allergic, antimicrobial and anti-stress properties and also helps in the treatments of asthma, arthritis, etc. Recent studies have indicated that Spirulina has a property of reducing heavy metals and nephrotoxic substance from the body. Studies confirm that this property is due to its combination and amazing concentration of nutrients
Spirulina is a generally safe and healthy food for most people. However, it is important to be aware of potential side effects and interactions with medications. It is also important to source spirulina from reputable manufacturers.
