New and improved recipe. MCT Oil. Be strong. Not hungry. Not all protein is the same, and neither are all protein bars. Bulletproof bars are made with collagen protein from grass-fed cows that provide essential building blocks for skin, joints and bones. Made with cashew butter and MCT oil for sustained energy and quality fats to satisfy hunger-each bar contains 11 g of protein and 2 g of sugar. Our bars are always gluten-free and provide delicious, on-the-go nutrition to support a healthy lifestyle. Bulletproof is an integrated approach to mind-body nutrition that helps transform the way you feel. Unleash your limitless potential.
