Frequently Asked
Questions

What is protein powder and how does it work?

Protein powder is a dietary supplement that provides a concentrated source of dietary protein, typically with little or no fat and carbohydrates. It works by nourishing the body with amino acids—the building blocks of protein—that the body needs to repair and build more complex molecules, such as muscle proteins, neurotransmitters, and peptide hormones.

Is protein powder good for you?

Protein powder can be highly beneficial for people, particularly active individuals and athletes, who struggle to meet their protein needs through whole foods alone; protein powder provides a quick and easy source of protein that's typically light on the stomach and convenient when you don’t have time for a complete meal.

What does protein powder do to your body?

Protein powder, much like protein found in whole foods, provides essential and nonessential amino acids that the body uses to build and repair body tissues, such as skeletal muscle, and synthesize neurotransmitters, hormones, enzymes, and more. 

Is it OK to have protein powder every day?

Yes, consuming protein powder daily is safe for most individuals. However, it's important not to rely on protein powders as your sole source of protein.

How much protein powder should I take per day?

Most protein powders can be taken anytime throughout the day as a supplement or replacement for whole food to increase your protein intake. However, whey protein powder is generally best taken shortly after exercise, whereas casein protein powder is ideal for nighttime before bed.

When should I take protein powder for best results?

The ideal time to consume protein powder is within 30–60 minutes after your workout—often referred to as the "anabolic window"—to support muscle recovery and growth. However, taking protein before a workout can also be beneficial by helping prevent muscle breakdown and jumpstarting protein synthesis.
