Unique Attributes Of Different Protein Types Dietary protein ingestion is critical to maintaining the quality and quantity of skeletal muscle mass throughout adult life. Sufficient intake of good quality protein is needed to promote muscle protein synthesis (MPS), provide strength and help to overcome weakness and fatigue. However, all proteins are not the same; they vary in terms of nutritional profile, digestibility, and bioavailability. Each protein source has unique attributes, which include divergent amino acid profile and different digestion rate that determines its ability to stimulate skeletal muscle protein synthesis (MPS). The quantity of protein consumed in a day is not the sole determinant of its potential to stimulate MPS. Significance Of Adequate Protein Intake Achieving adequate protein and energy intakes is more likely when protein is distributed evenly throughout the day. A single protein source may be rich in only 1 or 2 key amino acids and cannot provide an even distribution of protein through the day. Milk contains two protein fractions, whey, and casein, which are characterized as “fast” and “slow” proteins, based on their rate of digestion, respectively. Soy protein isolate (ISP) is more of an ‘‘intermediate’’ protein in terms of digestion rate based on plasma peak amino acid concentrations. Whey protein has higher leucine content. ISP and casein contain more glutamine than whey protein. Also, ISP supplies 3 times more arginine than either dairy protein. Hence, a single source of protein will be inadequate in providing an anabolic environment for MPS. An observational study showed a ~25% higher 24-h MPS with an evenly distributed protein intake compared to the skewed intake. Protein Combinations For Superior Muscle Gain Protein combinations with a range of digestion rates can produce superior gains in muscle mass compared with a single protein source or blends of protein with similar digestion rates. Thus, ingesting a protein blend which combines >1 type of protein will help capitalize on the unique digestive properties of each type of protein. This allows for an optimal blood availability of amino acids to increase the amplitude and duration of MPS stimulation. Horlicks Protein+ Contains Triple-Blend Of High-Quality Proteins Horlicks Protein + contains fast acting whey, intermediate-acting soy protein, and slow acting casein. Every serve## of Horlicks Protein+ with milk provides 33% protein (16 g protein$$) and 1.5 g leucine. A blend of protein with ≥2 types of proteins is typically done with the intent to capitalize on the unique digestive properties of each type of protein, optimize bioavailability of amino acids, and support muscle growth. Whey protein has been referred to as “fast” proteins as it is rapidly digested than casein and leads to a large rise in plasma amino acid levels. Soy protein is more of an “intermediate” or ‘slower acting ‘protein in terms of the digestion rates based on plasma amino acid concentrations vs. whey and casein. Casein has been referred to as “slow” protein compared to whey as the plasma appearance of dietary amino acids after a casein-rich meal is slower, lower, and prolonged. Thus, the triple blend of whey, soy and casein allow for both fast and prolonged release of amino acids supporting an increased amplitude and duration of MPS stimulation. Horlicks Protein+ delivers all 8 amino acids essential for adults namely threonine, lysine, methionine, valine, isoleucine, leucine, tryptophan, and phenylalanine.
