Whether you’re a certified fitness influencer or just a person who likes to casually work out, cheap protein powder is always a win. There’s nothing quite like a mostly-mixed shaker bottle full of protein shake after a gym session to make you feel like you’re doing your body right. Currently, Optimum Nutrition has discounted its Gold Standard Whey Protein for Amazon October Prime Day (aka Prime Big Deal Days), making this a great time to stock up. We picked this as our best protein powder for beginners in our best protein powders buying guide thanks to its affordable price and assortment of flavors, but it’s great for people at any fitness level.

 Optimum Nutrition protein powder nutritional information

Optimum Nutrition

This is your bread-and-butter basics protein. It offers 1.5g fat, just 3g carbs, and 24g protein. That’s a solid balance of macronutrients, and it comes in under $1 per serving. The macros may change a bit between flavors, but it stays fairly consistent. That flavor variation is actually one of the reasons we really like this brand of whey protein. You can pick from the list below and mix your powder however you like. Bake it into brownies, put it in your oatmeal, or fill a giant ant farm with it and slither around inside while you consume the precious proteins. I personally like the Double Rich Chocolate, which is why it got its picture on the page. It also holds up really well in my giant human ant farm. But there are other options available at various discounts, some of them even better than the above:

Prices are correct at time of posting but subject to change, so act fast.
