Each serving (31g scoop) of Nutrex IsoFit Whey Protein Isolate contains approximately 5.9g of BCAAs (branched-chain amino acids) and over 12g of EAAs (essential amino acids). These amino acids are naturally present in the protein and play a critical role in muscle recovery, repair, and performance.
In this article, we’ll explain exactly what these amino acids do, why their levels in Nutrex IsoFit matter, and how to use this information to maximize results in your training and diet.

Understanding BCAAs and EAAs
What Are BCAAs?
BCAAs are a group of three essential amino acids — leucine, isoleucine, and valine — that help:
- Stimulate muscle protein synthesis
- Reduce exercise-induced muscle breakdown
- Support energy during prolonged workouts
What Are EAAs?
EAAs are the nine amino acids your body cannot produce on its own, including the three BCAAs. They are:
- Histidine
- Isoleucine
- Leucine
- Lysine
- Methionine
- Phenylalanine
- Threonine
- Tryptophan
- Valine
Together, EAAs are vital for building and repairing muscle tissue, producing enzymes and hormones, and supporting immune health.
BCAA & EAA Content in Nutrex IsoFit
According to Nutrex IsoFit’s product label:
Per 31g Serving:
- BCAAs: ~5.9g total
- Leucine: ~2.7g
- Isoleucine: ~1.6g
- Valine: ~1.6g
- EAAs: 12g+ total
- Includes the 5.9g of BCAAs plus 6g+ of other EAAs
Why This Matters:
These numbers are considered optimal for post-workout recovery, as research suggests ~2.5g of leucine per serving is the threshold to maximize muscle protein synthesis.
Why the BCAA & EAA Levels in IsoFit Matter for Athletes
1. Faster Recovery
The rapid-digesting nature of whey isolate combined with a high BCAA content means muscles receive amino acids quickly after training.
2. Muscle Preservation in Calorie Deficits
During cutting or weight-loss phases, maintaining high EAA intake helps prevent muscle breakdown, supporting a lean physique.
3. Performance Support
BCAAs, especially leucine, also help reduce muscle soreness, allowing athletes to train more frequently.
Nutrex IsoFit vs Competitors: Amino Acid Comparison
| Protein Powder | BCAAs per Serving | EAAs per Serving |
| Nutrex IsoFit | ~5.9g | 12g+ |
| Standard Whey Concentrate | ~4.5g | ~9g |
| Grass-Fed Whey Isolate | ~5.5g | 11g+ |
| Vegan Pea Protein Isolate | ~4g | ~8g |
Verdict: Nutrex IsoFit offers above-average BCAA and EAA content compared to many protein powders, especially plant-based options.
Best Time to Take Nutrex IsoFit for Amino Acid Uptake
- Post-Workout: Maximizes recovery and muscle growth
- Morning: Prevents overnight muscle breakdown
- Between Meals: Maintains steady amino acid levels throughout the day
FAQ: BCAAs & EAAs in Nutrex IsoFit
Q: Are BCAAs in Nutrex IsoFit enough for recovery?
Yes — each serving contains more than the recommended leucine threshold for muscle protein synthesis.
Q: Do I still need a separate BCAA supplement if I use IsoFit?
Most athletes won’t need extra BCAAs unless training fasted or on very low protein intake days.
Q: Are the amino acids in IsoFit naturally occurring or added?
They are naturally occurring from the whey isolate, ensuring clean and complete protein quality.
The Bottom Line
Nutrex IsoFit delivers a strong 5.9g BCAA and 12g+ EAA profile per serving, making it ideal for athletes seeking fast recovery, lean muscle retention, and consistent performance. With its clean, low-carb formula, it’s a top-tier choice for anyone serious about results.
If you’re looking for a whey isolate that checks both performance and recovery boxes, IsoFit is worth adding to your supplement routine.
