Spirulina: A Complete Protein Source

Spirulina, a blue-green algae, is a complete protein with an exceptional 55–70% protein content, containing all nine essential amino acids (EAAs). It’s a powerful tool for addressing nutrient deficiencies. Below, we detail its amino acid profile and benefits.

Amino Acid Profile

Protein Content: 55–70%

• Essential Amino Acids:
  • Histidine: ~1.0 g/100 g (supports tissue repair and nerve function)
  • Isoleucine: ~3.0 g/100 g (aids muscle repair and energy production)
  • Leucine: ~4.5–5.0 g/100 g (promotes muscle growth and hormone production)
  • Lysine: ~2.5–3.0 g/100 g (enhances calcium absorption and collagen formation)
  • Methionine: ~1.0–1.2 g/100 g (supports liver function and antioxidants)
  • Phenylalanine: ~2.5 g/100 g (precursor to neurotransmitters)
  • Threonine: ~2.5 g/100 g (supports immune function and collagen production)
  • Tryptophan: ~0.8–1.0 g/100 g (supports mood and sleep regulation)
  • Valine: ~3.5 g/100 g (supports muscle repair and energy)
• Non-Essential Amino Acids:
  • Alanine: ~4.0 g/100 g (energy metabolism)
  • Arginine: ~3.5 g/100 g (blood flow and tissue repair)
  • Aspartic Acid: ~5.0 g/100 g (energy and neurotransmitters)
  • Cysteine: ~0.5 g/100 g (antioxidant support)
  • Glutamic Acid: ~7.0 g/100 g (neurotransmitter and energy)
  • Glycine: ~2.5 g/100 g (collagen and detoxification)
  • Proline: ~2.0 g/100 g (collagen synthesis)
  • Serine: ~2.5 g/100 g (immune function)
  • Tyrosine: ~2.0 g/100 g (thyroid support)

Nutritional Benefits and Uses

• Highest Protein Content: Ideal for boosting protein intake in small servings.
• Rich in EAAs: Exceptional leucine and lysine for muscle and immune support.
• Nutrient-Dense: Contains B vitamins, iron, and antioxidants like phycocyanin.
• Supplement Form: Add powder to smoothies or tablets for convenience; strong flavor may require masking.
• Considerations: Lower bioavailability due to cell wall; source from reputable suppliers to avoid contaminants.
