🥊 Combat Athletes: Why Omega-3 Should Be Your Secret Weapon?  

As combat athletes, we take hits and train hard. But are we giving our bodies - especially our brains - the protection they need? Let's talk about Omega-3! 🧠  

💥 Why It Matters for Fighters 

• Karate athletes = high impact (1 injury every 25 mins of competition!) 

• Near 60% of head & neck injuries in Olympic karate 

• Recovery is crucial for performance 

•  

🔬 Science-Backed Benefits 

• Reduces muscle soreness (DOMS) 

• Supports faster recovery 

• Offers potential brain protection from repeated head impacts 

• Helps manage inflammation 

🐟 Getting Your Omega-3 (Best Food Sources which low in mercury): 

• Anchovies, salmon, herring, Atlantic mackerel 

• Shellfish (shrimp, oysters) 

• Canned light tuna

• Plant sources: Limited conversion (not your best bet!) 

   

📋 Practical Guidelines: 

• O3I levels above 8% is pivotal for health & performance

• Aim for 2 servings of low-mercury fish weekly

• Supplementation: at least 2400mg EPA+DHA daily with 50%+ EPA/DHA content, maintain for at least 4.5 weeks 

• Timing of omega-3 supplementation is not mandatory 

• Vegetarian? Algae-based options available! 

• Avoid large dose supplementation in the first days post-injury 

• Choose trusted brands with 3rd-party certification (e.g. Informed Sports, NSF for Sports etc.) 

• Watch out for high Omega-6 foods (processed meats, fried & greasy foods etc.) 

 🔑 Key Takeaway: While Omega-3 is crucial, it's just one piece of the puzzle. Always prioritize a well-rounded diet first and consult with a registered sports nutritionist/dietitian before adding new supplements to your regimen.
