Overview of Spirulina: Nutritional Profile and Classification

Table of Contents

Nutritional Profile

The nutritional composition of Spirulina includes:

Component Amount per 100g
Protein 60-70g
Carbohydrates 13.6g
Lipids 5-10g
Vitamin A 3100% of carrots
Iron 5100% more than spinach

Spirulina also contains significant amounts of antioxidants, including phycocyanin and chlorophyll, which contribute to its health benefits (Sabat et al., 2025). Due to its rich nutrient profile, Spirulina has gained popularity as a dietary supplement, especially among vegetarians and health-conscious individuals.

Phycocompounds in Spirulina: Types and Health Benefits

Spirulina is a reservoir of bioactive compounds known as phycocompounds, which contribute to its health-promoting properties. These include:

  • Phycocyanin: A blue pigment with strong antioxidant and anti-inflammatory properties.
  • Chlorophyll: A green pigment that may aid in detoxification and improving liver function.
  • Carotenoids: Such as beta-carotene, which are known for their antioxidant effects.
  • Vitamins and Minerals: Including a range of B vitamins, calcium, magnesium, and iron.

These compounds work synergistically to enhance human health, showing effects such as immunomodulation, antioxidant activity, and anti-inflammatory responses (Sabat et al., 2025).

Antioxidant and Anti-inflammatory Properties of Spirulina

Spirulina’s antioxidant properties are primarily attributed to its high content of phycocyanin and carotenoids, which scavenge free radicals and mitigate oxidative stress. This action can lead to reduced risks of chronic diseases such as cardiovascular diseases and cancer (Sabat et al., 2025). Studies have shown that phycocyanin can inhibit the production of pro-inflammatory cytokines, thus exhibiting anti-inflammatory effects that may benefit conditions like arthritis and other inflammatory diseases (Sabat et al., 2025).

Health Benefit Mechanism
Antioxidant Scavenges free radicals
Anti-inflammatory Inhibits pro-inflammatory cytokines
Immunomodulatory Enhances immune response
Antimicrobial Inhibits growth of pathogenic bacteria
Neuroprotective Protects neurons from oxidative stress

Spirulina’s Role in Disease Prevention: Antibacterial and Antiviral Effects

Spirulina has been recognized for its antibacterial and antiviral properties. Research indicates that it can inhibit the growth of various bacteria, including Staphylococcus aureus and Escherichia coli, and viruses such as the herpes simplex virus and potentially SARS-CoV-2 (Sabat et al., 2025).

Antimicrobial Mechanisms

The mechanisms by which Spirulina exerts its antimicrobial effects include:

  • Disruption of Bacterial Cell Membranes: The compounds in Spirulina may interfere with the integrity of bacterial cell membranes, leading to cell lysis.
  • Inhibition of Viral Replication: Certain extracts can block viral entry into host cells or inhibit viral replication processes.

These properties suggest that Spirulina can play a significant role in preventing infections and supporting overall health.

Practical Applications of Spirulina in Nutrition and Industry

Spirulina’s versatile applications extend beyond dietary supplements. It is utilized in various industries, including:

  • Food Industry: As a natural colorant and nutritional supplement in products like smoothies, bars, and snacks.
  • Cosmetics: Due to its antioxidant properties, Spirulina is incorporated into skincare formulations to promote healthy skin.
  • Aquaculture: Spirulina serves as a feed supplement for fish and other aquaculture species, enhancing growth and nutritional value.

Its adaptation to various applications underscores its potential as a sustainable resource for improving human health and nutrition (Sabat et al., 2025).
