F
N+ Score54
ProteinServing: 36 Gram(s)Type: Amino acid/Protein

Nutrex Research Black Series Muscle Infusion Chocolate Peanut Butter Crunch is a protein supplement containing 8 ingredients. Each 36-gram serving delivers 25 grams of protein, 160 calories, 3 grams of fat, and 7 grams of carbohydrates. While the protein content is substantial for muscle support, the product's N+ Score of 54 and 'F' grade place it in the 'below average' tier. This score is partly influenced by the underdosed amounts of Calcium (127 mg) and Iron (1 mg) relative to their daily value percentages, suggesting they are not primary functional components. The product may be suitable for individuals seeking a general protein source, but it does not excel in micronutrient delivery or overall formulation quality according to its N+ Score.
