I recently tried two different types of protein powder from Optimum Nutrition. I first tried the Whey and Oats. The flavor I tried was Vanilla Almond Pastry and that's exactly what it tasted like. It tasted like an protein bar or granola bar, but a shake version. The scoops are large and contain 190 calories per serving, 4 grams dietary fiber, 16 grams carbs and a whopping 27 grams protein. This is made with premium whey protein and contains complex carbohydrates from whole oats. I mixed it with unsweetened almond milk and a banana. It was tasty and frothy and I felt full, using it as a meal replacement for both lunch and breakfast. My kids liked it, too. I used the blender and some ice and it all frothed up deliciously. It was convenient when I was out running around with the kids this past month. Our life has gotten extremely busy. I also enjoyed it after a mid-distance run and this powder is great recovery fuel! You can also mix it with water, but I much prefer mixing with milk or almond milk. The powder dissolved well, too.
We also tried the Greek Yogurt Protein Smoothie in Blueberry flavor. It tasted like a liquid blueberry muffin, when mixed with ice and unsweetened almond milk. I didn't mix this one with a banana. The Protein Smoothie version also comes in Strawberry or Vanilla. I tried this as an after snack and pick-me-up and it was refreshing while sitting out on our deck, watching the little ones play. It contains 130 calories per scoop, 8 carbs and 20 grams protein.
Neither powder had any weird clumps or after taste, something I've experienced with some other brands on the market.
I also am a HUGE fan of their Cake Bites. We've consumed dozens of packages of these tasty protein bites over the past year.
