The Top Evidence-Backed Health Benefits of Consuming Spirulina

Spirulina, a cyanobacteria prevalent in both fresh and saltwater sources, has rapidly become one of the sought-after superfoods. Recognised for its distinct blue-green colour, spirulina operates similarly to plants and gets energy from sunlight through photosynthesis. 

Historically, the Aztecs incorporated spirulina into their daily diet, and its potential was further discovered when NASA considered its cultivation in space to nourish astronauts. 

Today, spirulina has become very popular because of its nutrient-dense profile and many health benefits. 

In this post, you’ll learn the many science-backed health benefits of adding Spirulina to your diet. 

Historical Context: Spirulina Through the Ages

• Ancient Times: Believed to have played a pivotal role in transforming our planet's atmosphere from carbon dioxide-rich to oxygen-rich, Spirulina has been around for aeons, making it one of the oldest life forms. This transformation allowed for diverse life forms to thrive on Earth.

• Aztec Era: The nutritional wonders of Spirulina weren't globally recognized until the 16th century. The Aztecs discovered its benefits, turning it into edible cakes known as 'tecuitlatl'.

• Mid-20th Century: By the 1950s, the tradition continued in Mexico near Lake Texcoco, where natives referred to these dried cakes as "dihé," which became a staple food sold in local markets.

• Commercial Production: Spirulina's commercial production took off in the 1970s, pioneered by a French company, with countries like Japan and the USA quickly catching on.

The Top Health Benefits of Spirulina 

Spirulina didn’t immediately become a huge name in the health food industry. In fact, it didn’t become too popular until NASA utilised it as a dietary supplement for astronauts in outer space. 

Widely considered a prokaryotic lifeform, spirulina is one of the oldest microorganisms in the world and has been linked to the formation of the Earth and cited as the planet's first source of oxygen via the MIT Department of EAPS.

The world finally started to look more closely at spirulina and found this humble “algae” to contain an astounding amount of nutrients.

It is a sustainable food source that could potentially help fight world hunger. But aside from being a food source, raw spirulina can help improve many ailments such as allergies, high cholesterol, high blood pressure, anaemia, and fatigue.

Here are some of Spirulina's most useful health benefits: 

It Improves Metabolism Rates.

The high protein content in spirulina makes it beneficial for boosting metabolic rates. Proteins require more energy to break down compared to fats or carbohydrates, leading to increased calorie burning. 

Moreover, the B vitamins present in spirulina play a crucial role in energy production, aiding metabolic processes and ensuring efficient energy utilisation.

It Helps Maintain Healthy Teeth

Spirulina is rich in calcium and phosphorus, essential minerals for tooth health. These minerals are pivotal in strengthening the tooth enamel and preventing tooth decay. 

Additionally, the antimicrobial properties of spirulina can help combat harmful bacteria in the mouth, reducing the risk of gum diseases.

It Improves The Immune System

Spirulina is packed with antioxidants, notably phycocyanin, which combats oxidative stress in the body. This helps to bolster the immune system by protecting cells from damage. 

Additionally, spirulina has been shown to increase the production of infection-fighting proteins, antibodies, and other cells that improve immunity and help ward off infection and chronic illnesses.

It Helps Maintain Normal Muscle Function

The protein-rich nature of spirulina makes it an excellent supplement for muscle growth and repair. Amino acids, the building blocks of proteins, are essential for muscle function, and spirulina provides a complete protein source containing all essential amino acids. 

Furthermore, the magnesium and potassium in spirulina help in muscle contraction and relaxation, preventing muscle cramps and fatigue.

It Improves Cognitive Functions

Spirulina contains a good amount of Omega-3 fatty acids, amino acids, and antioxidants, all of which are beneficial for brain health. 

These components help protect the brain from oxidative damage and inflammation, potentially delaying or reducing the risk of cognitive disorders. 

Also, the B vitamins in spirulina support neurotransmitter function, which is vital for memory, focus, and overall brain function.

It Improves Cardiovascular Health

Spirulina is known to have a lipid-lowering effect. It contains gamma-linolenic acid (GLA), which has been studied for its potential to reduce bad cholesterol levels, potentially lowering the risk of cardiovascular diseases.

Its antioxidant properties may protect the heart by reducing inflammation and preventing plaque build-up in arteries.

It Helps In Blood Sugar Regulation

Studies have indicated that spirulina may assist in stabilising blood sugar levels, making it beneficial for those with diabetes or at risk of developing the condition. The algae can improve insulin sensitivity and reduce blood sugar spikes after meals.

It Helps Maintain Gut Health 

Spirulina is a source of probiotics that can support a healthy gut flora balance. By promoting the growth of beneficial bacteria in the gut it aids digestion and potentially combats issues like candida overgrowth.

Additionally, its anti-inflammatory properties can soothe and heal the gut lining, potentially benefiting those with conditions like leaky gut or irritable bowel syndrome.

It Promotes Skin and Hair Health

Rich in vitamins and minerals, spirulina can promote healthier skin and hair. Its anti-inflammatory and antioxidant properties can combat acne and skin ageing, while the protein, iron, and GLA content can contribute to shinier, stronger hair.

Is Spirulina Worth Adding To Your Diet? 

Spirulina's amazing nutritional profile and wide array of health benefits mean you should definitely add it to your diet. From supporting cardiovascular health to enhancing cognitive functions and promoting skin vitality, the evidence speaks volumes about its potency. 

But, like always, before making any significant changes to one's diet, it's advisable to consult with a healthcare professional to ensure it aligns with your needs.
