BCAA Complex

For faster recovery, lean muscle support, and workout energy.*

  • 30 servings with a clinically supported 2:1:1 ratio of BCAAs. Instantized means the powder dissolves easily in water without clumping, making it smoother to mix and drink. The 2:1:1 ratio is the clinically researched balance of branched-chain amino acids shown to support post-exercise recovery and muscle protein synthesis.
  • With glutamine and B-vitamins to aid recovery and energy. Many BCAA supplements include only the core amino acids. Our formula adds 3 grams of glutamine plus energizing B-vitamins to support muscle repair, immune health, and clean energy during and after training.

FAQs

What does it do?

BCAA Complex helps support muscle recovery, endurance, and lean muscle maintenance. With clinically studied branched-chain amino acids in the ideal 2:1:1 ratio, it fuels performance and reduces muscle soreness after workouts.*

Who is it for?

This is for anyone active, training regularly, or looking to support recovery between workouts. Whether you're strength training, doing cardio, or building stamina, it’s a clean, effective way to help your body bounce back faster.*

How soon will I feel a difference?

Many customers feel a reduction in muscle fatigue within the first few uses, especially when taken before or after intense activity. By the end of the first week, recovery often feels quicker, with less soreness between sessions. With consistent use, long-term benefits like muscle support, improved endurance, and sustained performance tend to build steadily over time.*

Is it safe to take every day long-term?

Yes, BCAAs are naturally occurring in protein-rich foods and are generally safe for daily use. When taken within recommended amounts, they can support long-term muscle recovery and performance. As always, consult your healthcare provider if you have specific dietary concerns.*

What if I’m pregnant, nursing, or on medication?

Please consult your healthcare provider before using if you are pregnant, nursing, taking medication, or have a medical condition.*

The perfect pairings

Consider pairing BCAA Complex with Creatine or Electrolytes to support performance and hydration, or Magnesium Glycinate to promote recovery and muscle relaxation after training.*

Supporting acts

Beyond supplements

It’s called a supplement for a reason. BCAA Complex is just one part of your daily ritual for faster recovery, lean muscle support, and workout energy. It’s here to add to what truly matters — what you eat, how you move, and the intentional choices you make each day.

  • Prioritize post-workout protein

    Meals or snacks rich in protein after training help repair muscle tissue and replenish energy. Pairing BCAA supplementation with complete proteins like salmon, chicken, or eggs supports recovery and lean muscle growth more effectively.

  • Train with intention

    Whether lifting, sprinting, or circuit training, focus on form and consistency over intensity alone. BCAAs help reduce muscle breakdown and delay fatigue, so you can stay strong and energized through each session.

  • Protect your recovery

    Deep rest is essential for rebuilding muscle and reducing soreness. Make sleep a priority, and give your body space to recover between sessions. When combined with BCAAs, this leads to better performance and long-term progress.

Love the formula with no junk!

No sucralose, no fake neon colors. Just a clean amino acid boost.

helps me push through long runs

Endurance during my weekly runs is way up since adding this to my routine. Would like more flavors to choose from but the melon one they have now is good. Do one with peach!

Dear Taylor, thank you for the feedback. We love hearing this. We’re so glad it’s making a difference in your runs! Peach sounds like an amazing idea, and we’ve passed your request along to our product formulation team. Thanks for being part of the Arken community and for helping us grow with thoughtful feedback. Best regards, Arken.
