Looking for an affordable snack that's satisfying and fits in with your health goals? You can enjoy great savings on a range of protein bars this Amazon Prime Day, including a 12 box of Quest Nutrition bars, now $20.99 at Amazon (opens in new tab), as well as our favorites, Misfits Plant-based Protein Bars, now $22.00 for a box of 12 (opens in new tab).

Bulk buying protein bars can be much more cost effective than buying a single bar from a grocery store or vending machine. In fact, while it might initially seem an investment, it can save you up to 50% in the long term. Not to mention, having a plentiful supply of protein bars to hand can help to curb mid-morning cravings, or provide a post-workout pick-me-up.

We've tried and tested a number of the best protein bars here at Live Science, rating them in terms of nutritional value, affordability and taste. Many of them are currently on offer as part of Amazon Prime Day 2022, making this a great time to stock up on protein-packed snacks.

Most protein bars contain at least 10g of protein, with many containing around 20g. This macronutrient can support lean muscle gain, as well as helping to keep you fuller for longer. So why not grab a box of your favorite protein bars for a generous discount this Prime Day?
