What is protein powder?

“Protein powder is a concentrated form of protein derived from various sources, such as animal products like whey and casein, or plant-based sources, like soy, pea and hemp,” explains functional nutrition practitioner Jenny Rich. The protein is processed into powder form for convenient consumption.

“Protein powders can be a great tool to meet overall protein goals since many women are under-eating protein at baseline,” says registered dietician Brittany Beaver. “The recommended dietary allowance (RDA) for protein is set to prevent deficiency, not for optimal health.” The ease of consumption can help one reach or maintain that baseline as part of an overall diet.

What to look for in a protein powder

“Added vitamins, minerals, probiotics, collagen and all 19 amino acids are something everyone should be looking for in a protein powder,” says Kylie Bensley, registered dietician and founder of Sulinu Nutrition. However, protein powders can be further vetted based on individual needs. To start, consider the powder’s protein source.
