High Biological Value 100% Whey Protein Isolate
We’ve seen some great athletes in our lifetime.
Miami Marlins outfielder Giancarlo Stanton smacking home runs out of the ballpark.
New England Patriots tight end Rob Gronkowski scoring touchdowns and spiking the football in the end zone afterward (the famous “Gronk Spike”).
Oklahoma City Thunder point guard Russell Westbrook recording triple-doubles in historic fashion (and earning the nod as 2017 NBA MVP).
Their performances in their chosen sport speak volumes.
Get this: they’re also endorsers of Six Star Whey Plus Isolate.

Russell Westbrook – 2017 NBA MVP and Six Star Pro Nutrition athlete endorser.
We’ve reviewed Six Star Pro Nutrition 100% Whey Protein Plus before.
It didn’t blow us away, but its formula held its own – a combo of whey protein isolate, whey protein concentrate, creatine monohydrate, glutamine, and maltodextrin should help you muscle up and shorten recovery time.
We’re curious to see if Six Star Whey Plus Isolate makes the grade as well.
This supplement “features a protein source with one of the highest biological values that is easy to digest, mix and absorb,” per Six Star Por Nutrition’s official website.
“It’s undergone microfiltration to remove the things you don’t want (like fats and lactose) and retain higher concentrations of the things your body needs, like BCAAs,” per the same source.
The company also says Six Star Whey Plus Isolate is “loaded with fast-absorbing BCAAs, glutamine, and micro-filtered whey protein to help you recover from your workouts.”
We love the phrase “highest biological value.”
Any time you see that in your protein supplement’s description, it’s a major plus – the fast solubility and absorption rates should help feed your muscles after a hard workout.
The microfiltration process is not unusual – it’s what most whey protein isolate products go through for maximum protein and minimum fats and carb content.
Speaking of which, we’re stoked about Six Star Whey Plus Isolate’s impressive 30 grams of protein per serving (equal to a solid 60 percent of the daily value).
That’s a lot of protein, folks.
It trumps those of big-name protein products such as Optimum Nutrition Gold Standard 100% Whey (24 grams per scoop) and MyProtein Impact Whey Protein (20 grams per scoop).
Take that.
We’re sure Six Star Whey Plus Isolate’s awesome protein content will help you pack on lean muscle mass and recover faster from your training sessions.
Count on it.
Now, let’s delve deeper into what a two-scoop serving of Six Star Whey Plus Isolate offers you, per the company’s official website:
- Twenty-four grams of amino acids
- 12.5 grams of branch-chained amino acids (BCAAs)
- 6.1 grams of leucine
- 11.5 grams of glutamine and precursor
- One gram of fat
- Zero grams of sugar
- Three grams of carbs
Can anybody say, “lean muscle growth?”
The amount of BCAAs Six Star Whey Plus Isolate has is right up there with other leading protein supplement brands.
Based on the manufacturer’s information, you will enjoy three grams of leucine – the most anabolic amino acid – or so per scoop.
That much will help kick your muscle protein synthesis into overdrive.
Seriously.
Five grams of glutamine per scoop is a fantastic bonus. Take our word for it, folks.
Glutamine is a versatile alpha amino acid. Check out its huge fitness and health benefits:
- Helps preserve muscle mass
- Ramps up human growth hormone (HGH) levels
- Increases athletic performance
- Shortens recovery time
- Keeps free radicals at bay
- Promotes healthy blood sugar levels
- Boosts memory, focus, and concentration
Whew.
The Golden Era of Bodybuilding icons supplemented with glutamine (their physiques are hard evidence of its benefits) – you should, too.
Now, things begin to get confusing.
Bearing in mind the above information for two scoops of Pro Star Whey Plus Isolate, here’s what the actual Decadent Chocolate flavor ingredients list says about one scoop of fats, sugar, and carbs:
There’s a bit of a disparity, isn’t there?
In fact, many customers have been griping about this product’s advertising – they claim it didn’t deliver what it promised.
For instance, they say the manufacturer advertised zero milligrams of cholesterol per serving for the Decadent Chocolate flavor online.
To their dismay, they found out it has 55 milligrams of cholesterol per serving when they received it.
Issues like this will tarnish a manufacturer’s previously stellar reputation, believe us.
Things go downhill from there, folks.
We spotted a few fillers (sucralose and carrageenan) in Six Star Whey Plus Isolate.
Not good.
Customers have also given its taste mixed reviews online.
We agree with them – while it’s not horrible, it’s not the best-tasting protein supplement on the market.
It’s average at best, in our opinion.
Our initial impression: Six Star Whey Plus Isolate’s new formula has good potential, but several issues (false advertising, fillers, and taste) get in the way.
It’s not a top-notch product, for sure.
Sorry, Giancarlo, Rob, and Russell.
Let’s check out the formula ingredients:
- Calories, 150: Many protein supplements have between 100 to 150 calories per serving. Six Star Whey Plus Isolate falls within that limit, so no worries.
- Calories from fat, 20: This amount is not high at all, as the next section attests.
- Total fat, 2 g: Six Star Whey Plus Isolate’s two grams of fats per scoop represents just three percent of the daily value (five percent at most has a low value). All good.
- Saturated fat, 1 g: This supplement’s saturated fat content is equal to just five percent of the daily value. Again, it doesn’t go overboard in this regard.
- Cholesterol, 55 mg: The first red flag – Six Star Whey Plus Isolate’s Decadent Chocolate flavor has 18 percent of the daily value for cholesterol (a value of at least 15 percent is high). The Vanilla Cream flavor is worse – it has 20 percent of the daily value. If you’re monitoring your cholesterol intake, better skip this one.
- Total carbohydrate, 3 g: Because of its microfiltered whey protein isolate content, Six Star Whey Plus Isolate is a good option to complement your low-carb diet. It’s not a significant source of carbs at all at a paltry one percent of the daily value.
- Protein, 30 g: Without a doubt, this is Six Star Whey Plus Isolate’s biggest strength – its protein content trumps those of Optimum Nutrition Gold Standard 100% Whey (24 grams per scoop) and MyProtein Impact Whey Protein (20 grams per scoop). That’s making a huge statement.
- Calcium, 90 mg: At nine percent of the daily value, this supplement’s calcium content is just so-so.
- Iron, 0.85 mg: Six Star Whey Plus Isolate is not a significant source of iron at just five percent of the daily value.
- Sodium, 190 mg: This product’s sodium content is neither too high nor too low. However, if you’re monitoring your sodium intake, better opt for a protein supplement with five percent or less of the daily value.
Formula Analysis
What do you get when three big-name athletes endorse a bodybuilding supplement?
Hype. Lots of it.
Did Six Star Whey Plus Isolate live up to the hype?
Nope.
Quite honestly, its 30 grams of protein per serving jacked us up. If you want to muscle up and shorten your recovery time, this much will do it for you.
No doubt about it.
The other components (BCAAs, glutamine, l-leucine, etc.) were just as impressive.
Five grams of glutamine and three grams of leucine per scoop will give you a fast return on your investment.
Expect increased muscle mass, human growth hormone levels, antioxidant protection, and athletic performance, folks.
Hard evidence: Giancarlo Stanton, Rob Gronkowski, and Russell Westbrook.
No kidding.
On the other hand, we like Six Star Whey Plus Isolate’s low fat (three percent of the daily value) and carb (one percent of the daily value) content.
Now for the downsides.
The manufacturer comes up short in three areas – transparency, filler content, and taste.
While Six Star Whey Plus Isolate has no proprietary blends, the company’s alleged false advertising has done them in.
Put yourself in the customer’s shoes – how would you react if you see 55 milligrams of cholesterol per serving on the ingredient label (while expecting zero milligrams per serving)?
Eighteen percent of the daily value for cholesterol?
No, thank you.
Six Star Whey Plus Isolate’s two fillers – sucralose and carrageenan – have several side effects.
Boo.
Finally, this supplement’s Decadent Chocolate flavor is just so-so. In fact, some customers say it’s downright terrible.
To each his own. For us, it’s just plain average.
There you have it, folks: Six Star Whey Plus Isolate has potential, but it has several gaping holes.
It’s not a terrible supplement, by all means.
It’s not top-of-the-class, either.
Six Star Whey Plus Isolate Benefits
Six Star Whey Plus Isolate has the following benefits, per its official website:
- One hundred percent instantized, micro-filtered WPI content
- Sixty grams of protein for every two servings
- No trans fats
- Low sugar and low cholesterol content
We agree with most of these claims (except for the low cholesterol claim). For all of its imperfections, Six Star Whey Plus Isolate can still be an asset to one’s training program. However, there are far better WPI products out on the market.
Who Takes It?
The manufacturer intended Six Star Whey Plus Isolate for healthy and active individuals who want to increase muscle mass, shorten recovery time, meet their daily protein requirements, and achieve their daily fitness goals.
Any Side Effects?
Six Star Whey Plus Isolate has a fairly high amount of cholesterol (18 percent of the daily value). Individuals who are monitoring their cholesterol levels should not take this supplement.
This product also has the artificial sweetener sucralose and additive carrageenan, which both have side effects.
The manufacturer also issues a warning:

Final Word on Six Star Whey Plus Isolate
It turns out Six Star Whey Plus Isolate’s 30 grams of protein per serving was one of its few bright spots.
Yeah, we like the glutamine, leucine, low-fat, and low-carb contents.
However, we just can’t get past the false advertising, high cholesterol level, fillers, and mediocre taste.
Way too many loopholes for our liking, folks.
With that, we recommend you skip Six Star Whey Plus Isolate. There are heaps of protein supplements out there on the market, anyway.
I love Six Star Whey Isolate. The Vanilla Cream is absolutely delicious! I have never tried the Chocolate. I am also very pleased with only 3 grams of carbs per serving! Mixes very well with my morning coffee. I have had no issues with recovery after pretty intense workouts. The Cholesterol is almost identical to other TOP brands. I cannot believe you made an issue of this? Last reason I love my six star is because the price is right. Very, very affordable. 4.5 stars out of five for me.
