Spirulina is a natural “algae” powder that is very high in protein and a good source of antioxidants, B-vitamins, and other nutrients. When harvested correctly from non-contaminated ponds and bodies of water, it is one of the most potent nutrient sources available.  It is largely made up of protein and essential amino acids.

Top 5 Benefits of Spirulina

Not everyone can get their hands on the optimal Hawaiian variety, but fortunately spirulina that’s produced includes very significant health benefits for people who regularly consume it. By regularly, I strongly recommend that you taking spirulina daily for the following reasons.

1. Detoxes Heavy Metals (Especially Arsenic)

Affecting people all over the globe, chronic arsenic toxicity is a problem. According to the World Health Organization, the U.S. is one of the countries affected by inorganic arsenic that is naturally present at high levels.

Arsenic toxicity is an even bigger problem in the Far East. In the words of Bangladeshi researchers, “Millions of people in Bangladesh, India, Taiwan and Chile are consuming a high concentration of arsenic through drinking water, and thousands of them have already developed chronic arsenic poisoning.”

In fact, up to 3 percent of the entire nation of Bangladesh showed clinical signs of arsenic poisoning alone. As Bangladeshi researchers pointed out, “there is no specific relief” for arsenic poisoning, which is why they evaluated alternatives like blue-green algae.

After giving 24 patients affected by chronic arsenic poisoning spirulina extract (250 milligrams) plus zinc (2 milligrams) twice daily, they compared the results with 17 patients who took a placebo and found that the spirulina-zinc combination worked. Ultimately, the participants experienced a 47 percent decrease of arsenic in their body. Spirulina against arsenic? Spirulina wins! Make it part of your heavy metal detox.

2. Eliminates Candida

According to researchers, “Candida species belong to the normal microbiota of an individual’s mucosal oral cavity, gastrointestinal tract and vagina.” What does that mean? Well, without a healthy microflora balance in our body, we are simply much more susceptible to sickness and disease.

In fact, leaky gut syndrome and improper digestion are directly connected to microfloral imbalance. Not only is invasive candidiasis the leading cause of mycosis-related death in the U.S., candida overgrowth has become the hallmark sign for most autoimmune diseases today.

Because of our shift toward a diet rich in sugar and unnatural ingredients, antimicrobial resistance and ineffective antifungal drugs, we have seen a significant rise in yeast infections since the 1980s.

Thankfully, spirulina appears to be able to help. Several animal studies have shown that it’s an effective antimicrobial agent, particularly for candida.

Specifically, spirulina benefits have been shown to promote the growth of healthy bacterial flora in the intestines, which in turn inhibits candida from thriving. Additionally, the immune-strengthening properties of spirulina will help the body eliminate candida cells. Spirulina against candida? Spirulina wins!

3. Improves HIV/AIDS

Up until recently, epidemiologists have been puzzled trying to understand why people in Japan, Korea and Chad have relatively low HIV/AIDS rates. One possible explanation, revealed in a 2012 study published in the Journal of Applied Phycology, may be the amount of algae people in these areas regularly consume!

When researchers took 11 HIV patients who have never taken antiretrovirals, they split the participants into three groups: one that was assigned to eat 5 grams of brown seaweed every day, one that was to eat 5 grams of spirulina, and one that ate a combination of both. After the three-month trial period was complete, two key findings were discovered:

Absolutely no adverse effects were experienced from both seaweed varieties and the combination.
CD4 cells (T-helper white blood cells that fight infection and are used to stage HIV) and HIV-1 viral load (another HIV biomarker) remained stable.

The results were so promising that one participant volunteered to continue the study for an additional 10 months, and this participant actually benefited from “clinically significant improvement in CD4 and decreased HIV viral load.”

4. Helps Prevent Cancer

According to the University of Maryland Medical Center, “A number of animal and test tube studies suggest that spirulina increases production of antibodies, infection-fighting proteins, and other cells that improve immunity and help ward off infection and chronic illnesses such as cancer.”

This doesn’t come as a surprise as more than 70 peer-reviewed articles have been published in the scientific literature evaluating spirulina’s ability to affect cancer cells.

In an article published this past April, Czech Republic scientists pointed out that, in addition to its ability to control blood cholesterol levels, “Spirulina is also rich in tetrapyrrolic compounds closely related to bilirubin molecule, a potent antioxidant and anti-proliferative agent.”

When tested on human pancreatic cells, these researchers discovered that, “Compared to cells that were not looked at, experimental therapeutics significantly decreased proliferation of human pancreatic cancer cell lines in vitro in a dose-dependent manner.” Essentially, this proves that consuming spirulina appears to be a potential natural cancer relief.

5. Lowers Blood Pressure

Phycocyanin is a pigment found in the spirulina that scientists have discovered possesses anti-hypertensive effects (it lowers blood pressure). Japanese researchers claim that this is because consuming the blue-green algae reverses endothelial dysfunction in metabolic syndrome.

I find this extremely promising for Americans because metabolic syndrome has rapidly become one of the main causes of preventable disease today, as it raises one’s risk of developing heart disease, diabetes and stroke.
