You’ve heard it said often that nature provides everything we need to survive. This is true. Granted, nature may not provide everything we want, but it does provide everything we need. One of the most abundant sources of nutrition and health is our oceans. One of the things the oceans provide is Spirulina, a scientifically proven source of nutritional needs and health benefits. Let’s take a look at the many things Spirulina can offer you when used appropriately.

What is Spirulina?

Spirulina is an algae that boast a green-blue coloring. It is found in the salty alkaline oceans in Asia, Africa, and Central America. This spiral-shaped plant grows freely in these areas and is sometimes in such a great quantity the waters surrounding it take on its coloring. In the United States, it has to be “farmed”. The unique environment that it grows in, specifically alkaline water, has made it considered by NASA as a possible nutritional source on space missions.

Records indicating the use of Spirulina go back to usage by the Aztecs. At the same time, these same algae were harvested in the Sahara Desert. Today, you can find Spirulina in pill or powder form in the nutritional supplement aisle of most stores and on the shelves of health food stores. Ongoing studies have indicated the possible benefits of this supplement.  It is no mystery when you see, what this superfood contains.

Protein, Carbohydrate, B-complex vitamins, beta-carotene, Vitamin E, manganese, zinc, copper, iron, selenium, gamma linolenic acid (an essential fatty acid)

With all these nutrients, it is no wonder that people are starting to praise the daily use of this supplement. Let’s take a list of some of the many benefits of Spirulina.

11 Spirulina Health Benefits

Spirulina has been undergoing scientific studies for some now and the possible benefits are numerous. Here are eleven of the benefits that are considered to be studied well. In addition to the benefits listed below, Spirulina has shown promise in helping alleviate symptoms of HIV and Hepatitis, relieve menstrual cramps and lower blood sugar levels. It has yet to be determined where the benefits of Spirulina end.

Rich in Protein.

Spirulina boasts a full fifty to seventy percent protein by weight. It also contains Vitamin B-12. Those ho follow a vegan or vegetarian lifestyle can certainly benefit from the added protein. For those who do have meat in their diets, you know how expensive meats can be. It would help to have an additional source of protein that could help you save money on your grocery bills. Many people find they are deficient in Vitamin B-12, which can result in eye problems and depression. The human body can’t produce B-12 and it is normally only found in animal products. Being able to get that additional B-12 can be a great benefit.

Allergy Relief.

Studies have shown that Spirulina inhibits the release of histamines, which are the culprits in allergy symptoms. With regular use, it has been shown that symptoms such as sneezing, itchy and watery eyes and other symptoms, such as nasal stuffiness, of an allergic reaction are greatly reduced.  

Controls Cholesterol.

Some of the greatest health problems in the United States are those related to the heart. These include high cholesterol and high blood pressure. While the greatest way to keep these things under control is to consume a healthy diet and participate in regular exercise, studies have shown that regular ingestion of blue-green algae has lowered both in elderly patients. Spirulina alone won’t cure either of these but may help reduce the number of medications you require to control both.

Oral Cancer.  

While more research needs to be conducted, several studies have been promising in regards to Spirulina reducing pre-cancerous abscesses that are in the mouth. Many of those who smoke or chew tobacco products are at increased risk to oral cancers. Nothing has yet been studied about whether or not oral cancer might be reduced, but the benefits on the early lesions are promising.

Boosts immunity.

The nutrients in Spirulina are high in anti-oxidants and have been found to boost the immune systems of the elderly. Regular consumption has been shown to prevent viral infections. Over time, white blood cell counts are shown to increase. These cells are the ones that fight illness in the human body. This increase is thought to be the reason immunity is boosted.

Improves Brain health.

Spirulina has been shown to improve cognitive functioning over a period of time. It contains L-tryptophan, which is necessary for the production of the neurotransmitter serotonin in the brain. This neurotransmitter plays a large part in mood regulation and sleep. Memory loss has been slowed with regular use of this supplement. Degenerative conditions like Alzheimer’s and Parkinson’s have been shown to slow with the addition of Spirulina to diet. It has also been shown to help with concentration, which may help those with ADHD focus better without any, or at least a reduction of dosage, medication.


We are subject to many impurities every day. They come in the air we breathe, the foods we eat and in many other places we don’t realize. Spirulina contains antioxidants that can help protect your body from the effects of these toxic substances. Inflammation not only causes pain but also is the cause of many diseases. Phycocyanin, which gives Spirulina its color, has been scientifically proven to reduce inflammation. Considering the regular use of medication to deal with the pain and swelling of inflammation has many irreversible side-effects, being able to reduce it even partially can help keep other organs in your body safer.


Anemia is a blood condition that is caused by the lack of red blood cells. Those with anemia often feel constantly tired and may feel cold all the time. This condition is especially prevalent in the elderly population. One study showed that Spirulina not only boosted the immunity of the elderly participants but it also helped increase the productivity of red blood cells, alleviating the anemia.

Athletic Benefits.

Studies have been conducted on athletes, who often fall victim to oxidative effects that cause them to lose strength and endurance. Spirulina improved both strength and endurance in half the studies and improved strength only in the other half. It remains to be seen how other studies turn out in regards to the endurance benefits for athletes, but the muscle strength enhancement is showing great promise.

Healthy skin.

Spirulina contains all eight of the essential amino acids you require. This is great news for your skin. The nutrients help increase the rate at which your skin rejuvenates; reducing the sallow look that is often present when skin production slows due to aging. The health benefits provided also add a glow to skin and help keep the moisture. This is due to the detoxing properties that are needed to undo the damage created by the free radicals that attack your skin on a daily basis.

Bone health.

Your bones need calcium to stay strong. As we age, our bones begin to lose their density. Regular use of Spirulina, which contains a high amount of calcium, has shown to help improve bone density. This could help prevent or slow the process of such disorders as osteo-arthritis and osteoporosis. This news is very encouraging to those who are lactose intolerant and may not be getting the required amount of calcium. Calcium supplements have been known to cause constipation, creating even more discomfort for those who take them. Spirulina may make the need for such supplements unnecessary.


Side Effects of Spirulina

Being a natural substance, this supplement is perfectly fine in the majority of people who use it. It is important to keep a few things in mind. Spirulina tends to absorb the things in the water around it so it is important to know where your particular source originates. If not careful, it is possible that it may contain heavy metals that can cause damage to your body. Most of the contaminated product comes from the shores of China and Japan, but do research to ensure your source is safe. Secondly, when it comes to nutritional supplements, more is not better. Read any instructions that come with your supply and do not take more than is recommended.

It seems like every week you hear of some new “superfood” that you just can’t survive without. Some have scientific evidence to back them up and others don’t. Spirulina is one of those with scientific and historic evidence to back up its claims. Can you live without it? Of course, you’ve made it this far in life without it. However, you have nothing to lose and possibly a lot to gain by giving it a trial run. You can’t go wrong adding some more vitamins and important minerals to your diet. In addition, many vegans like blue-green algae products because they are the only plants that contain Vitamin B12, one of the vitamins that the body can’t produce and one that is only available in meat products. Spirulina is something worth adding to your diet.
