What is Spirulina

Spirulina Health Benefits And Beyond

Spirulina, a blue-green algae that naturally thrives in saltwater lakes and oceans, is packed with protein, vitamins, minerals, carotenoids, and antioxidants, which play a crucial role in cell protection.

The Aztecs in Mexico and individuals from the Lake Chad region in Africa have relied on spirulina for centuries.1 However, it wasn’t until the 1970s that spirulina gained popularity in the United States. Presently, spirulina is readily available in the form of pills or powder and is a much-loved Super Green Diet supplement.

While researchers continue to explore the potential health Spirulina Health Benefits, there is evidence suggesting its effectiveness in managing conditions such as high blood pressure and high cholesterol. Continue reading to discover more about spirulina’s health benefits, nutritional profile, as well as important details regarding its safety and recommended dosage.

Nutrition Facts

Spirulina Health Benefits And Beyond

Spirulina is rich in various nutrients such as fat-soluble vitamins (A, E, and K), fatty acids (DHA, EPA), beta-carotene, and minerals. While it serves as a protein source, it may not provide sufficient levels of certain amino acids necessary for optimal bodily function, unless there is a medical requirement to avoid specific amino acids (e.g., phenylketonuria or “PKU”). As spirulina is derived from cyanobacteria, it can be considered a protein option for vegans.

It is worth mentioning that the B12 in spirulina exists in a different form known as “pseudovitamin B12,” which is not easily absorbed by the body. Therefore, it is advisable to seek alternative sources for meeting your B12 requirements, particularly if you follow a vegetarian or vegan diet that may be lacking in B12. Older adults above 60 also tend to have lower levels of B12. B12 plays a crucial role in red blood cell production, as well as brain and nerve cell development. Inadequate B12 intake can result in fatigue, memory loss, depression, and various types of anemia.

Possible Allergic Rhinitis Relief

Limited evidence suggests that spirulina may alleviate the symptoms of allergic rhinitis, commonly known as hay fever. A small-scale study conducted in 2020 revealed that spirulina exhibited greater effectiveness in reducing allergic rhinitis symptoms compared to the allergy medication cetirizine (Zyrtec). Although further research is required, these findings hold promise for the potential Spirulina Health Benefit in managing allergic rhinitis.

Anemia Management Support

Spirulina is a notable source of iron, leading to speculation about its potential benefits for individuals with anemia. Anemia is a condition characterized by low levels of hemoglobin or red blood cells in the blood. Insufficient iron levels impede the production of hemoglobin, which is responsible for delivering oxygen to the body’s tissues and organs.

A small-scale study demonstrated that supplementing with spirulina for twelve weeks yielded positive effects on hemoglobin levels, particularly among women aged 50 and above. However, further research is necessary to establish definitive conclusions.

Blood Sugar Regulation Aid

Individuals with diabetes or those at risk of developing diabetes are frequently seeking methods to manage their blood sugar levels.

A 2021 systematic review indicated that supplementing with spirulina in daily doses ranging from 0.8-8 g can lead to improvements in fasting blood sugar levels and lipid profiles among individuals with type 2 diabetes. However, further research is required to establish definitive conclusions.

Excellent Protein Source

Spirulina is a rich protein source, particularly for vegans or individuals following a plant-based diet. While it may not contain as much protein as milk or meat, with 4 g of protein per tablespoon, it offers more protein than many other plant-based sources.

Potential for Fatty Liver Disease Assistance

In a small-scale study conducted in 2014, it was discovered that incorporating spirulina supplements could potentially benefit individuals with non-alcoholic fatty liver disease (NAFLD). The participants in the study were administered a high dosage of spirulina (6 g) daily for a duration of six months. At the conclusion of the trial, notable improvements were observed in liver enzyme levels, triglycerides, total cholesterol, low-density lipoprotein-cholesterol, and the total cholesterol/high-density lipoprotein cholesterol ratios. These improvements indicate a healthier liver function.

Weight Loss Support

Spirulina holds potential benefits for individuals with obesity. A systemic review conducted in 2019 revealed that spirulina might contribute to a reduction in body fat percentage and waist circumference among those with excess weight. However, it’s important to note that this meta-analysis only encompassed five studies, underscoring the need for additional research to establish concrete conclusions regarding spirulina’s role in weight loss.

Potential Oral Health Improvement

There are indications that spirulina may have a positive impact on oral health. A 2013 study discovered that applying spirulina gel to the gums can alleviate symptoms associated with periodontitis (gum disease). Furthermore, evidence suggests that spirulina can combat oral submucous fibrosis (OSMF), a condition that has the potential to develop into cancerous lesions in the mouth. Nevertheless, further studies are necessary to deepen our understanding of these effects.

Precautions

Individuals with phenylketonuria (a condition that affects the processing of the amino acid phenylalanine) and those with other amino acid disorders such as classical homocystinuria (HCU) or maple syrup urine disease (MSUD) may need to exercise caution when considering the consumption of spirulina, as it is rich in protein and contains various amino acids.

The safety of spirulina for pregnant or nursing individuals has not been definitively established. It is advisable to consult with your healthcare provider before using spirulina if you are pregnant, planning to conceive, or currently breastfeeding.

It is important to note that children should not be given supplements, including spirulina, without prior consultation with their pediatrician.

Since spirulina grows in lakes, there is a potential risk of contamination with substances such as lead or other heavy metals, as well as toxins. Therefore, it is crucial to ensure that spirulina products come from trusted sources and undergo rigorous quality testing.

What happens if I take too much Spirulina

Spirulina is a type of blue-green algae that is often consumed as a dietary supplement due to its high nutrient content. While it is generally considered safe, taking excessive amounts of spirulina can lead to potential side effects. Here are some possible consequences of taking too much spirulina:

Gastrointestinal Issues: Consuming excessive amounts of spirulina may cause digestive problems such as stomach cramps, nausea, vomiting, diarrhea, or constipation. These symptoms are typically mild and subside on their own once the excessive intake is stopped.

Allergic Reactions: Some individuals may be allergic to spirulina. If you are allergic to seafood or have a known allergy to spirulina itself, consuming too much can lead to allergic reactions such as hives, itching, swelling, or difficulty breathing. If you experience any allergic symptoms, it is important to seek medical attention immediately.

Heavy Metal Contamination: Spirulina has the ability to absorb heavy metals from its environment, which can be a concern if the spirulina has been grown in contaminated waters. Taking large amounts of contaminated spirulina could potentially lead to heavy metal toxicity. Therefore, it is crucial to purchase spirulina from reputable sources that regularly test for heavy metal contamination.

Vitamin A Toxicity: Spirulina is rich in beta-carotene, a precursor to vitamin A. While the conversion of beta-carotene to vitamin A is regulated by the body, excessive intake of spirulina or combining it with other vitamin A supplements may lead to an accumulation of vitamin A in the body, resulting in symptoms of vitamin A toxicity. These symptoms include dizziness, nausea, vision problems, hair loss, and even liver damage.

To ensure safe consumption of spirulina, it is best to follow the recommended dosage provided by the manufacturer or consult with a healthcare professional who can guide you based on your specific circumstances and health conditions.

Potential Drug Interactions

Spirulina should not be taken concurrently with certain medications, including antidiabetic drugs, medications that suppress the immune system, anticoagulant medications, and antiplatelet medications. It is important to consult your healthcare provider if you are currently taking any herbal supplements, particularly those that have blood sugar-lowering or blood clotting-slowing properties, as combining them with spirulina may pose potential risks. It is worth noting that Spirulina naturally contains approximately 0.26 micrograms (mcg) of vitamin K per gram, and exceeding this amount could potentially enhance the blood-thinning effect of certain medicines.
