BCAA Dosage Calculator
The BCAA Dosage Calculator estimates your optimal daily BCAA dosage based on body weight, activity level, and fitness goals. This tool helps athletes and fitness enthusiasts maximize muscle recovery and prevent breakdown. Whether you are aiming for muscle growth, endurance support, or enhanced recovery, this calculator provides a precise plan to fuel your performance. Stop guessing your scoop sizes and ensure you get the exact grams needed to trigger muscle protein synthesis.
How Optimal Daily BCAA Dosage Is Calculated
Your optimal dosage represents the specific amount of branched-chain amino acids required to trigger muscle repair based on your unique physiology.
Dosage = Weight (kg) × Activity Multiplier × Goal Multiplier
Where Multipliers Adjust For:
- Activity Level: Sedentary (0.05) to Athlete (0.15) based on oxidation rate.
- Fitness Goal: Ranges from 0.9 for fat loss to 1.3 for recovery needs.
First, we determine your baseline needs by multiplying your weight by an activity factor. This step accounts for how many amino acids you burn daily. Next, we apply a goal multiplier to increase or decrease the dose based on whether you want to build muscle or maintain current mass.
Finally, if you select a training day, the result is multiplied by 1.2 to replace the extra fuel burned during exercise. This method ensures you hit the leucine threshold needed to stimulate growth.
What Your Optimal Daily BCAA Dosage Means
Your result tells you exactly how many grams of BCAAs to consume daily to support your specific training demands without wasting supplements.
Muscle Growth (12g – 16g)
If your result falls in this range, you are in the hypertrophy zone. Split this dose into two servings: take one 30 minutes before lifting and another immediately after. This ensures your blood amino acid levels stay high enough to build tissue.
Endurance Performance (8g – 12g)
For runners or cyclists, this dosage helps delay central fatigue. Sip this amount slowly throughout your long event to prevent your body from burning muscle for energy. It keeps you focused when you hit "the wall."
General Maintenance (5g – 8g)
This lower range is perfect for rest days or light activity. A single serving in the morning is enough to prevent muscle breakdown. It acts as a safety net for your diet to ensure you never run low on essentials.
Important Note
Remember that BCAAs are a supplement, not a total replacement for whole food protein. They work best when added to a diet that already includes high-quality protein sources like chicken, eggs, or whey.

Monitor your recovery and energy levels after a week of following the calculated dose. If you still feel excessive soreness, try increasing your intake by 1-2 grams.
