I ONLY buy all-natural protein (NO Aspartame/Acesulfame-k/Sucralose, NO chemicals or artificial colors/flavors/colors)! And anyone consuming protein is presumed to be inherently health-conscience, so why would anyone consider ANY protein powder with this crap in it? That is beyond me. There are 1,000 flavors (double-chocolate chip cookie dough, triple espresso fudge cake, cake batter, blue lemon truffle punch, etc...) I mean seriously? Are there millions of morbidly obese body builders out there who need their protein shake to taste like their favorite candy-bars and screw their health in the process?? Anyway, I'll get off my soapbox, but for the rest of you who don't want cancer or brain-tumors and actually care about what they shove into their bodies, then look no further than this protein powder! Ok, I've spent many days doing the research to see if I can de-throne my current protein king powder ("Optimum Nutrition Gold Standard 100% Natural Whey Protein Powder") which I absolutely love! But wanted to see if there was something better or just as good for cheaper. Enter this product. Now, this review is to compare these two highly rated kings! These 2 powders are the best of the best when it comes to All Natural. To help with the analysis, please refer to the attached diagram. So, the bottom line is that for $1.00... NOW=39g protein, ON=30.9g protein. So, with NOW, you get 26% more protein for the same buck! Hows that for a "dollar menu" analysis. They are both highly rated and are both EXCELLENT choices... however, the difference is the ON has sugar (yes, natural sugar!) and has natural flavoring, so of course humans like sweet things so it gets the edge on taste (10/10 in my book... I literally love it just as much as a milkshake and it isn't that sweet, just enough to be lightly evident but not unhealthy). Now, the reviews for this NOW said it tasted horrible and bitter and I was really afraid to buy it but due to the $ per gram of protein and appearing an even healthier choice compared to the ON, I thought I'd try it. Let me tell you, it is totally awesome! Now, not as awesome as the sugar sweetened ON, but for having nothing in it but 100% protein (no sweetner/flavors) it is totally OK!!! Now... let me preface these "taste" statements with one thing... I ALWAYS use milk in my protein shakes (16 oz milk - fat-free / 1% / 2% / whole) with 2 scoops protein, blend 20-seconds, drink. I thought I'd have to mix half/half of NOW/ON but I really don't. The NOW tastes just neutral, like I'm just drinking milk (which I love) but the same or even a little better than just plain milk. Now, given that NOW has no sugar/flavoring, it is a "more" natural choice compared to the ON.. and on top of that, has 26% more protein per $1.00 spent... I'm totally sold! If I'm in the mood I can flavor it with vanilla, honey, chocolate, peanut butter, bananna. Or, it tastes neutral enough to where I don't feel I have to drown the flavor out with any of those things... because at least with milk, it tastes great just by itself!! Plus, the NOW has the added benefit of being flavor-neutral for usage in recipes (w/o inadvertantly adding sweet/flavored(vanilla/chocolate) flavor to your favorite recipes. Another fringe benefit worth noting is that the NOW is still a 5.0 lb jug. It is not trying to sneakily down-size to 4.8lb (like the ON)... this is how manufacturers do it slowly so you're still paying the same $50/tub but the tub is now a wee-bit smaller... evil, evil, I say. Anyway, both of these are my absolute favorite proteins, but taking a deep-dive into the nitty gritty details... there has emerged one-clear winner to rule all of the natural proteins out there (IMHO). Thanks for reading and I hope this helps you (I took out 3 hours on my day off to put this review together for you!). Let me know if this was helpful to you or if you have any questions. thanks!
