Muscle building and recovery, post-workout nutrition, calorie and carbohydrate support, protein synthesis support
Active adults seeking convenient high-calorie, high-protein nutrition or people with fast metabolisms who struggle to meet calorie needs from whole foods alone.
Mix 1 serving (6 scoops) with 18–24 oz of water, milk, or a preferred beverage and shake or blend for 30–45 seconds; use 1–3 times daily between meals, 30–45 minutes after workouts, and before bed. Start with a smaller amount to gauge tolerance due to the high carbohydrate load. Protein powders are often well tolerated with meals or snacks.
Gluten Free. Contains: Milk.
Provides all essential amino acids, including leucine, which signals muscle protein synthesis and supports repair after exercise.
Caution: Contains milk proteins; avoid if you have a dairy allergy or are highly sensitive to lactose.
Rapidly digested carbohydrate that replenishes muscle glycogen and provides quick energy for training and recovery.
Caution: High carbohydrate load may not fit lower-carb diets; can affect blood sugar response, so monitor tolerance.
Acts as a conditionally essential amino acid that fuels rapidly dividing cells and may support muscle amino acid balance after strenuous exercise.
Caution: May cause mild gastrointestinal discomfort in some people; reduce dose if sensitivity occurs.
Soluble fiber that ferments in the gut to produce short-chain fatty acids, which may support a healthy gut environment.
Caution: Increasing fiber too quickly can cause gas or bloating; increase gradually with adequate fluids.
Protein-digesting enzymes that help break dietary protein into smaller peptides and amino acids for absorption.
Caution: Rarely, digestive enzymes may cause stomach upset; take with food and discontinue if discomfort persists.
Whey protein supplies essential amino acids for muscle building, while maltodextrin provides fast carbohydrates to refill glycogen and support workout energy needs. Added glutamine and protease enzymes support amino acid availability and protein digestion, and inulin contributes gentle fiber for everyday nutrition.
Label Warning: Consult a physician before use if you have any pre-existing medical conditions, take medication, plan a medical procedure, are contemplating pregnancy, are pregnant, or are nursing.
Who should be cautious: People with milk allergy or dairy sensitivity due to milk-derived ingredients. Those monitoring cholesterol or sodium intake may want to review the amounts per serving. Individuals on medications or with health conditions should discuss use with a healthcare provider before starting.
