Spirulina, often referred to as “miracle algae”, has conquered the world of nutrition and well-being thanks to its numerous health benefits. Considered a superfood, this blue-green micro-algae is packed with essential nutrients and is an essential part of a balanced diet. Whether you’re an athlete, in search of vitality, or simply concerned about your health, spirulina has a lot to offer. Let’s explore its benefits and how to incorporate it into your daily routine.
What is spirulina?
Spirulina is an edible cyanobacterium, often referred to as algae, although it is not strictly speaking an algae. Cultivated in warm, alkaline waters, it is harvested, dried and processed into powder, tablets or flakes for consumption. Used for centuries by civilizations such as the Aztecs, spirulina is now widely acclaimed for its exceptional virtues. According to a study published in 2022, spirulina is one of the most nutrient-rich foods on the planet, making it a valuable asset for global food security.
The nutritional benefits of spirulina
1. Rich in complete proteins
Spirulina contains up to 70% complete protein, i.e. all the essential amino acids. It is an excellent alternative for vegetarians, vegans and people wishing to reduce their meat consumption. According to a publication by the Institute of Nutrition and Health, spirulina proteins are also highly digestible, with an absorption rate of over 85%.
2. A concentrate of vitamins and minerals
Spirulina is packed with B vitamins, particularly B12, which is essential for the proper functioning of the nervous system. It is also an important source of iron, magnesium, calcium and zinc, all of which are crucial to overall health. A 2021 study showed that spirulina supplementation can reduce the risk of anemia thanks to its high bioavailable iron content.
3. Exceptional antioxidant content
Phycocyanin, the blue pigment found in spirulina, is a powerful antioxidant. It helps combat the free radicals responsible for premature ageing and contributes to strengthening the immune system. In 2020, researchers demonstrated that phycocyanin possesses remarkable anti-inflammatory properties, making it an ally in the prevention of many chronic diseases.
4. Natural energy source
Thanks to its unique composition, spirulina provides long-lasting energy without causing glycemic spikes. It is particularly prized by athletes for improving endurance and promoting recovery. A study of marathon runners revealed that daily consumption of spirulina significantly improves performance and reduces oxidative damage after exercise.
5. Promotes good cardiovascular health
Studies have shown that spirulina can reduce LDL (“bad”) cholesterol levels while increasing HDL (“good”) cholesterol. It thus helps prevent cardiovascular disease. According to American researchers, a dose of 4 grams of spirulina a day for 3 months can reduce triglycerides by 16%.
The health benefits of spirulina
1. Strengthens the immune system
Spirulina stimulates white blood cells and improves immune response. It helps the body better defend itself against infection and disease. Clinical trials have also shown that spirulina may reduce the frequency and severity of respiratory infections.
2. Detoxifies the body
Rich in chlorophyll, spirulina promotes the elimination of toxins and heavy metals from the body, helping to purify the organism. A study conducted in China demonstrated that spirulina can reduce lead toxicity in workers exposed to this metal.
3. Improves digestive health
Easy to digest, spirulina is gentle on the stomach. It promotes a healthy intestinal microbiota, essential for optimal digestion. Recent research has shown that spirulina can also reduce symptoms of irritable bowel syndrome.
4. Reduces inflammation
Spirulina’s anti-inflammatory properties can help relieve joint and muscle pain, particularly in arthritis sufferers. In 2021, a study revealed that spirulina reduces inflammatory markers such as CRP (C-reactive protein).
5. Helps weight loss
In addition to being low in calories, spirulina contains nutrients that provide a lasting feeling of satiety, which can help control appetite. According to one survey, 60% of people who consumed spirulina for 6 weeks reported a significant reduction in food cravings.
