When it comes to building lean muscle, not all protein is created equal — even if the label says “20 grams.”
At Muscle Up Bars, we use whey protein concentrate, and there’s a reason for that. Whey simply outperforms most plant proteins when it comes to building and repairing muscle.
🧬 The Science of Muscle-Building Protein
Your muscles rely on something called essential amino acids (EAAs) — especially leucine — to trigger muscle repair and growth after workouts.
Here’s how a few common proteins compare:
| Protein Source | Leucine Content (per 100g) | PDCAAS* | Muscle-Building Efficiency |
|---|---|---|---|
| Whey Protein Concentrate | 10–11g | 1.00 | ⭐ Excellent |
| Brown Rice Protein | 6–7g | 0.50–0.65 | ⚪ Moderate |
| Pumpkin Seed Protein | 6–7g | ~0.70 | ⚪ Moderate |
*PDCAAS = Protein Digestibility Corrected Amino Acid Score (1.0 = best possible)
🥩 Why Whey Wins
Whey protein is a complete, fast-absorbing protein source, delivering all nine essential amino acids in the right ratios to build lean muscle.
Brown rice and pumpkin seed proteins are great for plant-based nutrition, but they lack some key amino acids and have lower bioavailability — meaning your body absorbs and uses less of it for actual muscle repair.
In simple terms, you’d need 30–40% more rice or pumpkin protein to equal the same muscle-building effect as whey.
⚖️ The Bottom Line
If your goal is to stay strong, recover faster, and build lean muscle, quality matters more than quantity.
That’s why every Muscle Up Bar delivers high-quality whey protein concentrate — for people who read labels, care about what’s inside, and want real results from their nutrition.
