Pricey but good!

Great product. Mixes well in cold water or juice. Have to mix in small amount of water to dissolve clumps before adding to coffee or tea. If you add to hot coffee first it forms clumps that will be hard to dissolve. Overall, pricey but flavorless and can be used in baking as well.

Clean, smooth-mixing protein with a mild vanilla f

[This review was collected as part of a promotion.] This protein powder mixes easily and tastes good without being too sweet. The vanilla flavor is light and smooth. I didn't have any stomach issues after using it. The scoop is easy to measure, and it works well with water or milk. It's a little expensive, but the quality makes it worth it.

Great versatile protein powder for our family

We love the taste, it blends well and the price is great. We also use the chocolate flavor and bought a shaker bottle for my husband who just mixes it with water. I've made awesome sugar free cookies with a mix of the vanilla and chocolate powders and my teen son makes different smoothies with both powders.
