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.
