🔍 Whey Protein vs Plant Protein: The Core Differences
| Feature | Whey Protein | Plant Protein |
|---|---|---|
| Source | Milk-derived (dairy) | Pea, rice, hemp, soy, etc. (vegan) |
| Protein Quality | Complete protein with all amino acids | Varies; some are incomplete |
| Absorption Speed | Fast | Moderate to slow |
| Digestibility | Easy (unless lactose intolerant) | Generally easier on the gut |
| Muscle Building | High in leucine, great for muscle gain | Still effective, but slower |
| Allergen Concerns | Contains lactose | Dairy-free, allergen-friendly |
| Environmental Impact | Higher | Lower (more sustainable) |

💪 Is Whey or Plant Protein Better?
It depends on your goals and dietary restrictions:
- Choose whey protein if you want fast muscle recovery, are not lactose-intolerant, and want a high-leucine boost for strength training.
- Choose plant protein if you’re vegan, have digestive issues, or prefer sustainable nutrition.
Many people also combine both for variety and balanced amino acid intake.
🌱 Vegan Protein vs Whey: What About Nutrient Density?
Plant-based proteins often come with additional fiber, antioxidants, and minerals that whey doesn’t provide. However, whey still wins in terms of bioavailability and fast muscle protein synthesis.
