Zizi Bar is different from "legacy" heart bars because of supplements, calories and quality. Supplements: Other heart bars have 0.8 - 1g of plant sterols per bar. The Zizi Bar includes 2g of plant sterols and also includes 2.4g of red yeast rice. The Zizi Bar contains more than 4x as many supplement ingredients as other bars. Calories & added sugar: Other heart bars are 170-180 calories and include 5-6g of added sugar. We want to support your heart health without loading you up on calories and added sugars, so the Zizi Bar contains only 80 calories and no added sugar. Quality: The Zizi Bar is a dietary supplement, which means we commit to additional testing and quality requirements above and beyond food products. Legacy heart bars are food products, and do not commit to this additional testing.
