Milk Protein Isolate
Milk Protein Isolate
Snapshot
Milk Protein Isolate is a high-purity dairy protein containing both casein and whey fractions, offering balanced amino acid delivery with minimal lactose and fat.
What is Milk Protein Isolate?
Milk Protein Isolate is produced by filtering skim milk to remove most lactose and fat, yielding a powder with ≥90% protein comprised of soluble whey proteins and micellar casein.
Where It Comes From
Derived from dairy via cross-flow microfiltration and ultrafiltration processes; conforms to dairy protein standards for minimal lactose content and high protein concentration.
Key Nutrients & Compounds
Provides all essential amino acids with a 80:20 ratio of casein to whey proteins, delivering both rapid and sustained amino acid availability for muscle protein synthesis.
Health Benefits
Supports both immediate and prolonged muscle recovery; enhances anabolic response; promotes satiety; and suitable for lactose-sensitive individuals due to low residual lactose.
Recommended Dosage
20–30 g per serving post-exercise or between meals; adjust based on total daily protein needs and training intensity.
How to Use It
Mix Milk Protein Isolate powder with water, milk, or in smoothies; blend thoroughly to ensure solubility; consume within 30 minutes of exercise or as a protein snack.
Who Should Use It?
Athletes, fitness enthusiasts, and those seeking a high-quality protein source with both fast- and slow-digesting fractions; beneficial for lactose-sensitive users.
Possible Interactions or Cautions
Generally safe; individuals with dairy allergies should avoid; ensure adequate fluid intake to facilitate renal clearance of increased protein load.
Final Thoughts
Milk Protein Isolate offers a versatile, high-purity protein blend, making it an excellent choice for comprehensive muscle support and dietary convenience.
