For starters, this isn't your run of the mill whey protein powder. This powder consists of protein, cocoa, natural sweeteners, and that's about it. This is ideal for people wanting a completely natural protein and are steering clear of artificial sweeteners (sucralose and similar compounds).

One result of the lack of artificial sweeteners is that this protein won't taste like chocolate brownie a-la mode. I can best describe the taste as being "weak" and "unoffensive". It's not very thick, so I would advise using less liquid as opposed to more when mixing. And as always, this formula tastes better with milk than with water.

There is one primary competing product this this one made by Optimum - which I had bought previously. The only real difference between the Optimum Natural Whey and this Met-Rx formulation is the lack of protein enzymes to aid in digestion. Everything else seems identical. For the roughly $10 per jug savings over the Optimum product, I would say this is a worthwhile tradeoff for most people.

Worth a review, for sure.

I just bought it AGAIN... and will continue to do so as long as price point and quality hold...

It's exactly what it says - natural whey, vanilla.

Clean - not loaded with artificial stuff, definitely the one I'd pick again, out of all the brands out there.

Flavor - fantastic - as whey goes, that is - honest, not chemical-ish.

Nice price at the time, no sucralose, and the easiest mixing, most easily digested whey I've found


My particular credentials: Years of using many different whey products, concentrate, isolate, whatever...

Update: One more important safety tip - when natural (or any) whey goes past it's sell-by date it will go bad on you. Flavor, odor, and consistency subtly change at first - then dramatically. Toss it at that point, it's no longer your friend.

I am not a nutritionist. Not even close. But as I approach 40 and have recently tried to resurrect my athleticism I have taken to a much better diet. Cut out a lot of junk food, lowered my carbs (not eliminated...just won't do that) and upped the protein greatly.
In looking at about 15+ different whey protein powders to start taking...I found a lot of them that had an additive called sucralose in them. It is an artificial sweetener that really has no redeeming qualities whatsoever. This was one of the few that did NOT have that. And as for value ($$/oz.) this was hard to beat.
The taste really is good. If mixed with milk it basically tastes like chocolate milk. Mixed with water is tolerable...but by far not my first choice. It may depend on what else you plan to either add, or intake shortly before or after. (probably don't want to mix with milk if you plan to eat or drink something very acidic soon). I have not yet tried to mix it with anything other than milk (2%) or water as far as the 'liquid' portion goes. However...my morning ritual is 8oz 2% milk, 1 scoop whey protein, 4 tablespoons organic vanilla yogurt, one heaping spoonful of peanut butter, and a healthy shake of chia seeds. That is what I have for breakfast every morning now. I have a very big appetite and that holds me over for a few hours (usually close to 4).
There are other ones out there that may do different stuff...but this one has worked for me. And it tastes good. And the price is unbeatable. What more do you want?

I had to give up on my favorite protein, ON Gold Standard Natural Whey, because I could no longer justify it financially (especially since the recent decrease in volume / same price point). Searching for something new that was quality and still easy on the wallet, I stumbled upon MET-Rx Natural Whey. It has turned out to be a great alternative. Coming from ON, it did take a little time to adjust too the new flavor. I think it's basically on par with Gold Standard but I felt my first couple of shakes were too sweet. That's what I liked about Gold Standard, it didn't taste crazy fake sweet like some of the others on the market. After a few rounds of the MET-Rx, I have adjusted and don't mind the sweetness at all, it feels toned down now. It doesn't taste like fake sweetener to me either. Also, it mixes even better than Gold Standard. I tried the chocolate first and will do the vanilla next.

Flavor Name: Peanut Butter CupSize: 2 lb Verified Purchase
I checked the labels on all the protein powders offered on Amazon, and I settled on this one because it had the lowest carb-to-protein ratio at the lowest price,...AND it came in a flavor not only not offered by many others, but one of my favorites in all things. I've had other protein shakes before;...strawberry, chocolate, vanilla,...and they all still tasted like a gritty powdered drink flavored to disguise the granular thing you were really drinking. But this was a very pleasant difference from those past experiences with other products. This actually tastes good all on its own and separate from its properties as a supplement. I truly enjoy drinking this stuff. And the flavoring is strong enough that I can even mix this with soy or almond milk and STILL taste great,...and I don't much like soy or almond milk.

I highly recommend this for your use if you think other formulas have not been that tasty.
