✅ Omega-3 Fatty Acids (EPA & DHA)

• Promote cognitive sharpness and recovery from mental fatigue
• Improve decision-making under pressure — especially in endurance and team sports

✅ Vitamin B12 + Choline

• Key for myelin repair and neurotransmitter synthesis
• Enhance motor learning and focus under high neural demand

✅ High-Quality Protein

• Supports neuromuscular repair and neurotransmitter building blocks (e.g., tyrosine, tryptophan)
• Low carbohydrate load aligns with ketogenic or targeted performance nutrition strategies

✅ Micronutrients (Selenium, Zinc, Iron)

• Help mitigate oxidative stress and fatigue
• Critical for oxygen transport and brain metabolism under prolonged physical load

• High sodium content — beneficial post-exercise but requires caution for salt-sensitive individuals
• Lower fat and cholesterol profile than Beluga — may suit lean performance diets better
• Smaller egg size and subtler flavour make it ideal for inclusion in light recovery meals or as a garnish
