Best Whey Protein Isolate Sample Sizes of 2024
Winner - TransformHQ Whey Protein Isolate
Whether your goals are building muscle, shredding fat, or maintaining cardiovascular health, getting enough protein can be tough for many people. I didn’t know I was protein deficient until I plugged my numbers into a protein calculator! With my body mass and fitness goals, I should eat at least 200 G of protein daily, which can be tough to get through meals and snacks alone. However, it is totally achievable with the help of whey protein isolate.
There are several kinds of protein, and I prefer whey isolate due to how it’s processed. Isolate is processed a bit more than other forms of protein. This results in whey protein isolate having higher protein content and lower fat and carbohydrates per serving.
With the massive amount of online options, it can be tricky to find the right whey isolate. Which whey isolate provides tons of protein per serving? Which is the most affordable and provides a hefty amount of servings?
Also, which protein powder tastes the best and is high-quality?
After ordering, tasting, and researching, I have picked five GREAT options and ranked them for you.
Without further ado…(drumroll, please)... I present the best Whey Protein Isolate Sample Sized Powders of 2024!

What I loved:
There is lots to love here. If you don’t have room for a bigger container, this 7 oz tub is perfect.
I ordered the Vanilla Creme Brulee, and I loved it. Transform HQ's Vanilla Creme Brulee has a super tasty Creme Brulee that isn't too sweet. It mixes well in the shaker bottle and was a bit foamy, but not too much. I thought it was totally delicious. Each serving provides 25 G of instantized whey isolate, which is probably why it mixes so easily. It also has just 120 calories.
Transform’s formula has no extra sugars, which is nice and straightforward. There is zero fat (just 0.5 grams per serving) and trace amounts of carbs, sodium, calcium, and potassium. I like that there are no fillers or unnecessary ingredients.
The last thing I love about Transform HQ’s whey protein isolate is the high-quality product. Transform HQ has gone the extra mile to manufacture its product in a state-of-the-art facility. Their protein isolate is manufactured in a GMP-compliant and FDA-registered facility. This definitely makes them shine bright on the market.
What could be better:
I realize that not everyone likes Vanilla Creme Brulee as much as I do. If you’re not into the Vanilla Creme Brulee, check out 4 other delicious flavors on this list.
Also, not everyone likes the smaller tubs, and would prefer a bigger tub, which TransformHQ offers if you like this flavor.

What I loved:
There is a lot to love here. Nutricost is an up and coming brand that has 100's of products on their website and Amazon. They are incredibly low priced on most of them. This particular sample pack is one of the lowest priced deals I've seen out there. Especially when you include the free shaker bottle.
I especially liked the Milk Chocolate, as it tasted as good as any chocolate on the market. Vanilla and Strawberry Milkshake were really good too, and I only liked them a little less because of my taste preference for chocolate.
They mixed pretty well after a little time. It wasn't the overall smoothest, but overall one of the better ones that I tasted.
What could be better:
The only real downside for me was that I would have liked to taste a few more of their different flavors. But with that price, I couldn't possibly complain too much.

What I loved:
Okay, so there is lots to love here. If you don’t have room for a big 5LB container, this 1.7LB tub is perfect.
Levels is a solid brand that boasts grass-fed whey that has no added sugars, soy, gluten or fillers.
There is zero fat (just 0.5 grams per serving) and trace amounts of carbs, iron, calcium, and potassium. I like that there are no fillers or unnecessary ingredients.
The thing I love about Levels whey protein isolate is that it is such a high-quality product. Levels manufacture's its product in a state-of-the-art facility. Their protein isolate is manufactured in a GMP-compliant and FDA-registered facility. This definitely makes them shine bright on the market!
What could be better:
While I like the smaller tubs, they are slightly less cost-effective. This tub has 14 servings, which could last for two weeks if you take one scoop per day, and the tub costs $24.99. When you look at the overall price, it is super affordable for a tub of protein isolate. When it comes to the price per serving, it is more than other brands on this list at $1.79 per serving.
Remember, if you’re tight on space in your pantry, this 14 serving pack of protein makes way more sense than the bigger 2-lbs. It just depends on your top factors for making a purchase.

What I loved:
Naked Whey is known for their no frills formulas to use the least amount of ingredients as possible. That is something I prefer as someone that tries to eat foods that are as clean as possible. I love that about Naked Whey Products.
I also liked that I could sample the two different flavors and one unflavored types, which is a good way for me to figure out what flavors I preferred. As far as my preference, I liked the vanilla flavor as it wasn't overpowering like some other brands that I've tried. The unflavored was as you would expect as it was as neutral as you could get for unflavored. As always with unflavored, I generally chug it down or mix it as a shake with some fresh fruit.
The pricing was also a big plus, at only $8.99 for the three sample packs. There's no better way to find out what you like by getting samples. It was a great way for me to decide if I wanted to get a larger tub.
What could be better:
I wasn't a big fan of the chocolate flavor, as it felt like a watered down version of chocolate milk. I preferred using the unflavored and adding what I liked than the chocolate flavor. However, I always remember that taste is subjective and some people might like the less sweet taste.

What I loved:
- 8 sample packs of 4 different flavors (2 of each)
- Fast digesting
- $29.96 for 8 sample packs
- Mixes Well
- Contains naturally occuring BCAA's
What could be better:
- A little expensive for my taste
- Non-traditional flavors
What I loved:
E-flow is a brand that is new to me. I was excited to try some new flavors that weren't the traditional chocolate and vanilla flavors. I was glad that I found that one of the flavors really tasty. The S'Mores flavor is one of my favorite whey protein flavors I've tried in all of the tests.
What could be better:
I was pretty excited to try the other flavors as well, but the other three weren't what I was hoping for. I would have loved for them to include some other flavors, like chocolate or vanilla, or some other flavors that Eflow has. I would have loved to compare their chocolate to other chocolate's of other brands.
I also wish that I could have had it at a little lower of a price. I am glad that the S'more flavor was excellent and I may try that flavor in a larger capacity.

What I loved:
- $12.99 that includes three samples and a shaker bottle
- Instead of a traditional milk-based proteins, a clear citrus-based protein
- 20 G of protein per serving
- Digests Quickly
- Made In A GMP Compliant, FDA Registered Facility
- Smooth mix
What could be better:
- The flavors
What I loved:
Animal has a unique take on protein powders. Instead of the traditional whey powder that looks like a shake, they've come up with a different way to do whey. They have a whey that looks like a citrus drink with fruit flavors. I was intruged and had to try it. My favorite tasting one was watermelon limeade. The other two, blueberry acai, and pineapple orange, weren't as good, but were passable.
I appreciated that they included a shaker bottle, though it wasn't the best quality or necessary. The all mixed well, and were a refreshing break from the traditional powders and flavors I'm used to with other whey powders.
The price was right as well, as it included 3 sample packs and a shaker bottle for just $12.99.
What could be better:
The watermelon Limeade was pretty great while the others were mediocre. There was a slight aftertaste but that is normal for me with citrusy drinks.

I ordered the Chocolate, and I enjoyed it. Transform HQ's Chocolate compares well with other chocolate Whey Protein that I've had before. It mixes well in the shaker bottle and was a bit foamy, but not too much. I thought it was totally delicious. Each serving provides 25 G of instantized whey isolate, which is probably why it mixes so easily. It also has just 120 calories.

TransformHQ wins with a strong brand reputation, a great price, and had 7 servings per tub, and an amazing unique Vanilla Creme Brulee flavor, and high-quality assurance because it is made in a GMP-compliant, FDA-registered facility, TransformHQ Whey Protein Isolate gets my #1 ranking by a big margin.
My Review Process
Here are the factors I considered for this review after researching, ordering, and trying them:
- Formula
- Quality
- Pricing
- Flavor
Here's why those 4 factors above were extremely important to me when it came to ranking the top ten Whey Protein Isolate powders:
1. Formula
With so many different products available, I wanted to take into account what exactly is in each powder.
2. Overall Quality
In the supplement world, things seem like they have the potential to get a little crazy. That's why brand reputation is such a big factor for me. That said, I took into consideration the band's presence on Amazon, the amount of reviews they had, and I also looked into what other people were saying about these products.
3. Pricing
Since whey protein isolate powders can range widely in price, another factor I considered in my rankings was the price per tub. With prices increasing everywhere, I know it is essential to keep spending as low as possible.
4. Flavor
It’s gotta taste great. I mixed up each one of these whey protein isolates to give you my personal opinion, as well as a general opinion on the flavor. I have tried countless protein powders, so I know what is standard in the industry and share my take on each one.
What is Whey Protein Isolate?
While shopping for whey protein, you will likely see many options. The two most common forms of whey protein are “Whey Isolate” and “Whey Concentrate.” Isolate is more highly processed and contains more protein, less fat, less carbs, and less lactose than concentrate (often less than 1%).
Whey protein isolate is a high-quality protein supplement made from the liquid component that separates from milk during cheese production. It’s a source of vitamins, minerals, branched-chain amino acids, and all nine essential amino acids.
You can throw this powder in a shaker with your desired beverage. You can also add it to smoothies, yogurt, cereal, use it to make protein bars, and more to help reach your daily protein goals.
Benefits of Whey Protein Isolate
Many people think Protein = Big, Bulky Muscles. Well, not so fast.
Most people don't get enough protein. No matter your diet and exercise- for example, if you’re on a plant-based diet or working out regularly- you should calculate your daily protein intake to ensure you’re getting enough.
You might want to supplement your diet with protein powder for many reasons beyond chasing that dream body.
Here’s a quick list:
Weight Management
Protein suppresses appetite by reducing your level of hunger hormones, and it also boosts metabolism.
Bone Health
People who eat more protein experience greater bone mass retention as they age. Increasing protein can help support healthy bones.
Muscle Recovery
That makes sense, right? Protein contains all the building blocks your body uses to repair itself, so when your muscles need to recover, the materials to do it are right there.
Minimizes Muscle Loss
Whether you are trying to gain muscle at the gym, maintain muscle while managing weight loss, or age gracefully, supplementing with whey protein can help prevent muscle loss.
What If I’m Lactose Intolerant?
Whey isolate often contains less than 1% lactose and is generally safe even if lactose intolerant.
However, particularly sensitive individuals may want to consider a plant-based protein supplement if whey isolate proves too much.
What is a protein intake calculator? Where do I find one?
Protein intake calculators factor in your weight, activity level, and fitness goals to help you figure out how much protein you need daily. There are many online, and I have used the one by Examine.com, which doctors review.
It is so convenient and easy to use - just type in a few numbers, and you’ll get your daily recommended protein intake.
