💪 1. What Is Select Protein?

Select Protein is PEScience’s flagship whey + casein blend, formulated using milk protein isolate as its primary ingredient. This premium blend is designed to be low in carbs, fat, and sugar, delivering 24 g of protein per 31–32 g serving with only ~120 calories.

It’s widely praised for its irresistible dessert-inspired flavors, developed in-house to taste exactly as named, making it the protein you’ll crave every day.

🥛 2. The Power of Whey + Casein

Whey and casein are the two primary proteins in cow’s milk, making up roughly 20% whey and 80% casein. Both are complete proteins with high levels of essential amino acids and branched-chain amino acids (BCAAs) like leucine, isoleucine, and valine, which support muscle protein synthesis and metabolic health.

Select Protein uses two protein sources: milk protein isolate (which naturally contains an 80:20 casein-to-whey ratio, is over 90% protein by weight, and has less than 0.5 g of lactose per serving), and whey protein concentrate, to bring the whey to casein ratio to a balanced ~50:50.

✨ 4. Benefits of Whey and Casein, and the Blend

Whey Benefits

  • Fast absorption post-workout
  • Bioactive proteins (e.g., immunoglobulins, lactoferrin)
  • Anti-inflammatory and immune-supportive

Casein Benefits

  • Slow digestion (4–5 hours)
  • Bioactive peptides improve calcium absorption and cardiovascular health

The Blend Advantage

  • Fast + slow amino acid delivery
  • More effective muscle protein synthesis
  • Higher satiety and better texture
  • Minimal lactose; easy on digestion

⏰ 5. How & When to Use Select Protein

  • Post-workout: Fast absorption aids recovery
  • Between meals: Curbs hunger, prevents catabolism
  • Before bed: Casein sustains amino acid levels overnight

Mix 1 scoop with 6–8 oz of water or milk. Blend with ice for added thickness.

🍦 6. Top Flavors You’ll Crave

🍰 6B. The Best Protein for High-Protein Recipes

Select Protein isn’t just for shakes, it’s the #1 protein powder for high-protein recipes.

Because it combines both whey and casein, Select Protein delivers a moist, fluffy texture in recipes like:

100% whey proteins dry out in baking, leaving a gritty, chalky texture. Select Protein’s blend congeals perfectly when heated, providing a rich, soft-baked consistency that elevates protein-based treats.

Pro tip: Try Cake Pop or Snickerdoodle in muffins or pancakes for a bakery-style experience.
