Core Nutritionals Pro Sustained Release Whey Protein Blend with Digestive Enzymes | 25g Protein, 2g Carbs | 5 lb Chocolate Peanut Butter Cup

Overview and flavor-forward nutrition

Core PRO Sustained Release blends fast-uptake whey with slow-digesting micellar casein to create a steady stream of amino acids across the day. The result is a protein shake designed to feel refreshing during recovery and easy to sip without the heaviness that some multi-source formulas can bring. Each 5 lb tub in Chocolate Peanut Butter Cup delivers 25 g of protein and just 2 g of carbs per serving, with no fillers in the formula. The flavor aims for a dessert-like indulgence while staying protein-forward, providing a satisfying aroma and rich mouthfeel that many athletes crave after training.

Beyond protein density, the formula includes a digestive enzyme blend to support digestion and nutrient uptake. The proteases work with the amino acids in the mix, and a portion of MCT fats may offer energy-friendly fatty acids to help sustain performance and post-workout recovery. This combination is designed to support a smoother fueling experience without lingering heaviness or bloating.

All day fuel and recovery

The protein matrix is designed for ongoing amino acid availability, pairing fast-uptake elements with sustained-release proteins sourced from cold-processed whey and micellar casein-rich milk proteins. This synergy may help support muscle repair and growth opportunities across long days or extended training blocks, without the need for constant reloading.

• Generous BCAAs in naturally occurring ratios to support fatigue delay and recovery timing
• Digestive enzymes to promote absorption and nutrient uptake
• Low carbohydrate profile to fit different fueling plans
