PhD bars are deliciously yummy and moreish. They are noted for being high in protein but low in sugar. Take PhD Smart Bar Chocolate Peanut Butter which is great tasting but high in protein and low in sugar. As with many bars they do not use palm oil.
One other interesting feature is their triple layering which is also a feature of bars like Grenade. The protein content is about 20g high quality protein per bar with 2g of sugar. The protein is a blend of milk protein (not isolate), collagen hydrolysate and soy protein isolate.
