What You Need To Know About MAN Sports ISO-Protein

Each serving contains 25g of pure protein and comes in a choice of sweet flavours including Donut Sprinkles, Blueberry, and Confetti Cake. Despite the ultra sweet flavours MAN Sports ISO-Protein is sugar free, but with its refined whey protein isolate, artificial sweeteners, sodium, and flavourings, it all looks extremely processed so will not suit you if you are trying to stick to a natural diet. The high price will probably put many customers off.

Our Verdict On MAN Sports ISO-Protein

MAN Sports ISO-Protein looks to be a good quality supplement but it comes at the pricier end of the market so with only 30 servings per container, it does not seem to offer the customer very good value. That said, it probably will work in the way as described, and if you use it to support a training regime or as a meal replacement you may find it helps you.

However we can’t pretend to be impressed by the choice of ultra sweet flavours and the additives and if you are looking to clean up your diet, this shake will not tick your boxes. In addition, the lack of customer feedback and the high price lets this supplement down. Overall, we do not recommend MAN Sports ISO-Protein to our readers.

MAN Sports ISO-Protein Review

MAN Sports ISO-Protein is a protein supplement that will suit you if you are looking for a shake to use as a post work out supplement or a meal replacement.

It contains just whey protein isolate as the active ingredient and each serving contains 25g. There are no additional extras such as vitamins and additional amino acids, all the nutritional benefits are delivered by pure protein alone.

Whey protein isolate is probably the best type of protein to take if you are looking to lose weight or fat. Whey protein Isolate, like whey protein concentrate is derived from milk but is processed to remove fats and lactose. Isolates contain 90% of protein per weight, compared with concentrates which contain between 29% and 89% per weight.

This means that you get more protein per serving and not only more amino acid content, less fat. Whey protein Isolate contains a full amino acid spectrum, so provides you with all the building blocks of protein which will help you build muscle. We also have written about the best one minute protein mug cakes and our top three protein shakes without using protein powder.

MAN Sports ISO-Protein Facts

  • Flavour range: Sprinkle Donut, Loopy Fruit, Mint Chip Ice Cream, Confetti Cake, Blueberry Muffin, Peanut Butter Bits, Chocolate Milk, and Vanilla Ice Cream
  • Each 2lb canister contains 30 servings
  • Each serving delivers 25g of protein

One point that the advertising focuses on, is the range of flavours. These include Sprinkles Donut, Mint Chip Ice Cream, Loopy Fruit (fruit loops), and Confetti Cake. Other more mainstream flavours include Blueberry Muffin, Peanut Butter Bits, Chocolate Milk, and Vanilla Ice-cream. If you like sweet flavours you will probably love them!

Interestingly the ingredients label states that there is zero sugar in the shake. However on closer inspection the shakes do contain artificial sweeteners that are up to 650 times sweeter than sugar. Other ingredients include “natural and artificial flavourings”, so this supplement will not suit you if you are trying to “eat clean” as many people put it. Source

How to Take MAN Sports ISO-Protein

  • Add 1 heaping scoop of ISO-PROTEIN in 8oz of cold water or milk
  • Make sure to shake well for full mixability, you are recommended to use a shaker cup
  • You can vary the amount of liquid based on the consistency and taste you desire
  • Consume 1 serving of ISO-PROTEIN within 30 minutes of your workout
  • You can also consume ISO-PROTEIN throughout the day based on your desired protein intake requirements

Overall MAN Sports ISO-Protein looks reasonably good. It delivers a reasonable serving size of good quality protein and contains only 110 calories if you add to water.

MAN Sports is a US company based in Texas. The address is provided as a PO Box in Mesquite Texas, but there is a customer phone line so presumably you can get hold of the company should you need to.

MAN Sports ISO-Protein Concerns:

  • This supplement is expensive compared to many other whey protein supplements on the market
  • Contains sodium, sweeteners, and artificial flavourings
  • The Shake comes in a choice of flavours but all are very sweet and sickly. If you don’t have a sweet tooth you may find it undrinkable

MAN supplements are on sale from online retailers such as AI Nutrition in the USA, MuscleWorx in Australia, and Power Myself in the UK. US customers can also find them on the shelves at The Vitamin Shoppe.

We have covered other MAN supplements in previous reviews including MAN Sports Sweat CompoundMAN CLA Powder, and MAN REM–PM, a natural sleep aid.

What Does MAN Sports ISO-Protein Claim To Do?

The advertising bills this shake as “The Best Tasting Protein on The Planet” that is “hands down the industry’s most anticipated whey protein isolate to date”

Anticipated by whom we wondered, but there are no further details to back up this claim.

There are two key features:

Not all isolate protein powders are created equal. We only use the highest yielding instantized whey protein isolate in ISO-Protein™. This means 90% of the total isolate protein is complete or usable protein, the highest yield available on the market.

Taste and mixability isn’t everything but it plays a huge part in the user experience. It’s much easier to stick to a supplement regimen when you actually enjoy (or crave!) what you’re drinking! ISO-Protein™ comes in easy to mix, super-delicious Blueberry Muffin, Peanut Butter Bits and classics like Chocolate Milk & Vanilla Ice Cream.

Does MAN Sports ISO-Protein Work?

Yes, it should work if you use it to replace a meal or power a workout. Although the claims in the advertising seem overblown, It does contains 25g of protein per shake and only 110 calories, so if you are looking to help build muscle and lose fat we feel that this supplement will probably help. If you are training at the gym and use this supplement correctly we can see that it will work just as well, if not better than the many of the other protein supplements on the market.

Some supplements deliver more protein per serving, but we like that this one includes only whey protein isolate is defined quantities. Less impressive is the lack of fibre which is sometimes added to shakes but as the major point of this supplement is that is contains only Whey Protein Isolate and nothing else, this is not surprising. In addition, ISO-Protein is quite high in sodium although not in dangerously high quantities.

Whether or not you enjoy drinking the stuff will be the deal breaker for most people.

I bought the blueberry muffin and peanut butter bits. I liked the blueberry so much that I put it back in my cabinet to save for later. I didn’t want it all gone at once. Then I opened the peanut butter bits and I loved it even more than the blueberry! These are now my go to post workout drinks!

I bought the peanut butter bits flavor and it is amazing. I was very surprised and happy to see how large the container was! I always drink it after my workouts now and it’s perfect….

I have the blue berry muffin flavor and it’s absolutely amazing, it doesn’t have that “protieny” taste to it . I mix it in my oatmeal every morning…..

I tried the PB Bits for the first time and it’s amazing! A nice true PB flavor. No terrible aftertaste or funky smell in my shaker cup. Mixes easily on the go with water and ice….
