If you've been shopping for protein powder, you've probably noticed two names dominating every shelf: whey protein and pea protein. One's been the gym standard for decades. The other is newer, plant-based, and growing fast. So which is actually better?
What Is Pea Protein? Pea protein is made by extracting protein from yellow split peas. At Prookie's 80% purity, you get 24 grams of protein per 30g scoop — no dairy, no soy, no gluten.
What Is Whey Protein? Whey is a byproduct of cheese production. It's a complete protein with high leucine content — the amino acid most linked to muscle protein synthesis. Fast-digesting with a decades-long track record.
How Do They Compare? Whey scores higher on the DIAAS scale (around 1.09 vs 0.82 for pea). But a 2015 study in the Journal of the International Society of Sports Nutrition found pea protein produced equivalent muscle thickness gains to whey over 12 weeks of resistance training. If you eat a varied diet, the amino acid gap fills itself naturally.
Digestibility Many people find whey causes bloating or digestive discomfort — especially with lactose sensitivity. Pea protein is dairy-free, easier on the gut, and digests more slowly which may support better satiety.
Choose Pea Protein If You:
- Are lactose intolerant or dairy-free
- Are vegan or vegetarian
- Want a shorter, cleaner ingredient list
- Have digestive sensitivity to whey
The Bottom Line For muscle building, both work. For clean eating and digestibility, pea protein wins. The best protein is the one you'll actually use consistently — and if a one-ingredient label matters to you, it's hard to beat.
