Noun
protein powder (countable and uncountable, plural protein powders)
A food supplement created to provide a greater share of protein than natural nutrition.
For 'The Rise of Cobra,' I was dieting more and using protein powder to help supplement my meals. For 'Retaliation,' however, I opted for more natural protein. I had a chicken breast and broccoli meal about five times every day. I also drank plenty of water and made sure I got enough rest. Lee Byung-hun
I start off my morning with an Acai berry smoothie. I blend the Acai berries with kefir, blueberries, protein powder and peanut butter. I like this first thing in the morning because it's light on my stomach. Charity Shea
