Product Details:

Bodybuilding.com Casein Protein: 8-hour muscle power.*

In case you're unfamiliar with casein's slow-flowing style, it's the go-to protein any time your muscles hunger for a long-lasting meal.

While whey is ideal post-workout because it digests quickly, casein digests slowly and is optimal between meals or before bed. During these crucial hours, casein is a great protein source for a slow-release amino stream. Guess what? Slow and steady wins the race.

While casein isn't as directly anabolic as whey protein, it is helpfully anti-catabolic, which means that it can help prevent muscle breakdown and support around-the-clock repair.* You can even mix it with whey for a particularly powerful protein cocktail.

I've tasted many protein powders over the years and this one ranks in the top 3, and quite frankly could be my favorite. The Cnnamon Bun is fantastic. I've mixed it with both water and skim milk and can drink it either way. For a change up I'll add a little extra cinnamon to it or a little nutmeg just to break the manotiny but it's not needed. Until I find something better this will be my go to pre-bed protein drink.

This is a good casein at a good price. It is a really nice treat before bedtime, and that extra boost of protein doesn't hurt either. I will say that the flavor of this is very mild, I feel it could have a bit more vanilla-ness to it. The directions say to mix with 10 ounces of liquid, when I use straight milk the taste of the casein is overpowered, but if I use less than 10 ounces it gets way too thick after it sits a minute. I find that 6 ounces milk + 4 ounces water makes a nice base and I can enjoy the vanilla flavor better. Beware, though, casein powders in general are sticky and stick to everything, leaving powdery messes in their wake :)

So far so good. I take this strictly at night and cinnamon bun is a great tasting favor.

  • 9 Chocolate

Meets my cutoff of $10/lbs and tastes pretty good. Has that thicker and potent taste like most caseins but is a good choice

I've tried several brands' of Casein and this one is up there with the best--at a better price! It also has less of the after-taste usually associated with Casein. I usually take it with milk before bed. I'm switching to this Casein from the more-expensive brand I was using before... this is just as good, tastes better, and is more affordable.
