H2N Nutrition Diet Protein Ultra Review

H2N Nutrition are back under the microscope in this brand new supplement review.

Diet Protein Ultra is their latest, let’s see if it’s their greatest…

H2N Nutrition hail from my part of the world, and are a company I like to share as often as I can because they have a reputation for creating solid products.

However, as always, I will not hold back in this review.

Just like any other supplement, Diet Protein Ultra is going through my deliberately harsh supplement rating system and, just like the rest, it’ll get shredded if it fails to deliver on the promises it makes.

For the record, no supplement has ever received a 5 star review (yet)…


H2N Nutrition Diet Protein Ultra – The Good

There are many good points to this product.

If you’re a long-time follower of mine, you’ll know I was a big fan of the original formula for this product.

Known as H2N Nutrition Diet Whey, I once described it as “the best tasting whey protein supplement of all time.”

And I’m pleased to say Diet Protein Ultra stays on top of things in the taste game.

But taste is subjective.

If we really want to test the quality of a product, we need to get stuck into the ingredients…

Each 39 gram scoop from H2N provides us with 144 calories in the shape of:

  • 31g protein
  • 2.5g carbohydrates
  • 1g fat

The formula consists of whey protein concentrate, milk protein concentrate, and soya protein isolate.

This is a great macronutrient breakdown.

Diet Protein Ultra has an 80% protein-per-serving ratio, putting it at the top end of the whey protein marketplace.

What is a protein-per-serving ratio?

Well, we want as much of our scoop as possible to be protein. But many supplement companies like to stack their product with unnecessary “filler” ingredients, allowing them to sell poor formulas at premium prices.

In some cases, less than half of your scoop is protein.

So in terms of “bang for your buck”, these guys deliver. Massively.

To put this into perspective, the ever-popular Pro Jym has a ratio of 60%. Optimum Nutrition Gold Standard Whey has a ratio of 74%. Myprotein Diet Whey has a ratio of 65%.

Diet Protein Ultra also ensures it provides us with enough protein to stimulate muscle protein synthesis, at a mighty 31 grams per serving.

That’s higher than the baseline target of 22 grams, which was shown as the “sweet spot” for kick-starting hypertrophy in a 2009 study. (1)

This is great.

The protein formula is a blend, too.

If you’re a long-time reader you’ll know this is another good move, as studies clearly show that using a blend is superior to using one source of protein. (2)

Diet Protein Ultra contains whey protein concentrate, milk protein concentrate and soya protein isolate.

Whey protein concentrate is a fast-release source, soya protein isolate will take a little longer, and milk protein concentrate (which is a combination of 20% whey and 80% casein) is a slow-release form of protein.

This is ideal, as the combination will provide a very steady release of amino acids for your muscles to gobble up.

Finally, Diet Protein Ultra packs an impressive serving of taurine.

Each serving contains 1.2 grams but, considering the customer will likely consume more than one shake per day, this pushes the taurine serving beyond the clinically proven daily dose of 2 grams.

This unlocks the full benefits of taurine, which include better mental focus and blood flow. (3, 4)

Diet Protein Ultra – The Bad

I’m yet to come across a ‘perfect’ supplement.

And this is no different.

Alongside all the great stuff above, we get a “fat burning matrix”.

These are commonplace in ‘diet whey’ products, yet they rarely add anything to the quality of the product.

Diet Protein Ultra contains a combination of 195mg acetyl l-carnitine, 585mg CLA, 156mg green tea extract, and 546mg acai berry extract.

Research on CLA is inconclusive, while green tea extract has a very undeserving reputation as a ‘fat burner’. (4, 5, 6)

But the inclusion of these ingredients enables supplement manufacturers to make claims regarding weight loss and enhanced fat burning.

H2N Nutrition Diet Protein Ultra Review – The Final Verdict…

Well… it’s crunch time.

How does H2N Nutrition Diet Protein Ultra compare to the leading products in the whey protein market?

More importantly…

Will it become another member of the zero stars club?

As you can probably tell from the review above, it’s in no danger of joining the zero star club.

Diet Protein Ultra is a very solid whey protein supplement, ticking many of the boxes required to separate the ‘great’ from the ‘good’.

The high protein-per-serving ratio, the inclusion of a blend, and a whopping 31 grams of protein per shake make this a standout supplement which deserves a lot of credit.

H2N Nutrition have taken their original product – a firm favorite of mine – and made it even better.

It receives a mighty 4 stars from me.

You can buy it from their website.
