Frequently Asked Questions
What is the best way to take Muscle Matrix?
Add 1 heaping scoop of Muscle Matrix casein powder to 6-8 ounces of cold water or beverage (milk, almond milk, rice milk, juice, etc.) and mix in a shaker cup. To make a creamy smoothie, add 2-3 ice cubes and put in a blender for 20-30 seconds. Vary the amount of liquid to meet your desired taste and consistency. Consume 1 scoop within 20 minutes after your workouts. Consume 1-3 servings daily as needed to satisfy your protein requirements, which are often calculated based on your body weight. Do not use it as a sole source of nutrition.
When is the best time to take Muscle Matrix?
Muscle Matrix should be taken at nighttime (right before sleep) and within 20 minutes after workouts to help provide sustained amino acid delivery during the two most crucial times of muscle growth: during sleep and post-training. The slow-digesting casein forms in Muscle Matrix, supporting prolonged protein absorption.
Is consuming too much protein bad for your kidneys?
Absolutely not. This is a myth. No scientific literature shows that eating a high-protein diet has any detrimental effects on renal function in otherwise healthy individuals.
How should I stack NutraBio Muscle Matrix Protein with your other products?
We suggest taking one of our versions of PRE 30-45 minutes before your workout, Intra Blast during, and Muscle Matrix immediately after.
Can’t I meet my daily protein requirements through a regular diet?
While it is possible to meet daily protein requirements through a balanced diet, some individuals find it challenging to get the 1.5-2 grams per kg/bodyweight necessary to maximize muscle growth and promote recovery. Whole food sources such as milk, cheese, and cottage cheese are excellent options for casein protein, providing additional vitamins and minerals. However, food sources may not always be convenient, which is why individuals often turn to protein supplementation as a convenient way to meet their individual protein needs.
Are whey isolates superior to higher-quality whey concentrates — such as WPC 80?
Yes, and no. Whey isolates are 90% pure protein, while higher quality whey concentrates will be ~80% pure protein — making isolates “superior” on a gram-for-gram basis. However, both forms of whey digest rapidly and help support muscle-building and recovery goals. At the end of the day, which one you choose really depends on your goals. If you need a protein that is lower in calories and free of fats, lactose, and cholesterol, go with an isolate. On the other hand, if you need a protein that is more calorie-dense and fat-laden, which may be beneficial when weight gain is the goal, choose a high-quality whey concentrate.
How is casein or whey protein made?
Both casein and whey proteins are derived from milk during the cheese-making process. Enzymes are added to coagulate the milk, separating the curds (casein) from the whey. The curds are processed into various casein forms, while the liquid whey is filtered and dried into powder.
What are the health benefits of casein protein?
Casein protein supports muscle growth, recovery, and helps prevent muscle breakdown due to its slow digestion rate. Additionally, casein peptides found in casein protein may help support healthy blood pressure and metabolic health as part of a balanced diet.
