A Quick Look at NOW Sports Whey Protein Isolate

NOW started in 1968 as a natural health product company and has since grown into an award-winning brand with a wide range of products that includes health foods, supplements, essential oils, and even health foods. 

NOW takes food purity and safety very seriously, with an ISO-certified in-house lab that performs over 19,000 tests on various products every single month. All formulas are produced in NOW’s GMP facilities in the USA or Canada. 

This particular formula uses whey protein isolate, which is one of the many types of protein powder on the market. Whey protein isolate has gone through extra processing to remove fat and lactose, resulting in a protein with less total fat, total sugars, and cholesterol than standard whey protein. 

Whey protein isolate also digests slightly faster than standard whey or casein proteins, though protein timing doesn’t seem to be as important as many companies claim, with studies showing that your muscle-building potential is increased for up to 48 hours after training1.

NOW’s whey protein isolate is only available in three flavors, including an unflavored option, which isn’t super common. GGR tester Lauren Strong, CPT, tried the unflavored whey protein isolate powder during her hands-on testing.

Before You Buy

  • NOW uses high manufacturing standards and quality ingredients, so you can trust the quality of your protein. 
  • This whey protein isolate is one of the more affordable whey protein isolates we’ve tested, though it’s only available in three flavors if you include the unflavored powder. 
  • The unflavored option mixes well with other flavored ingredients but doesn’t taste all that great on its own, so you’ll want to mix it with something that has a stronger flavor.

Is NOW Sports Whey Protein Isolate Worth It?

NOW uses high manufacturing and testing standards to create trustworthy supplements that won’t empty your bank account. At $1.32 a serving, this protein powder is no exception, but that doesn’t mean NOW Sports Whey Protein Isolate is the best fit for everyone.

Before you buy anything, you need to make sure this is the right product for your goals. 

Great for:

  • Anyone looking for a protein source that’s high in protein, but low in total calories
  • Active individuals who are looking for a protein supplement to help improve muscle strength and recovery
  • Those who often get digestive issues from whey protein, and prefer to use isolates for easier digestion

Not recommended for:

  • Anyone who’s following a dairy-free diet and needs to avoid all dairy sources
  • Those looking for variety and taste over quality

Experience Using NOW Sports Whey Protein Isolate

When Lauren tested NOW Sports Whey Protein Isolate, she ordered the unflavored option. She said that the unflavored option didn’t taste very good mixed in plain water and had a bit of a strange aftertaste.

She added that it would taste great mixed into a smoothie with other flavors, and user reviews say they enjoy using the unflavored option to add protein to baked goods and other recipes. Flavor aside, Lauren said the protein mixed very well and didn’t cause any bloating or discomfort.

Price Per Serving

NOW Sports Whey Protein Isolate earns a rating of 4.5 out of 5 for pricing, with a price of $1.32 per serving for the unflavored version in the smallest size, which is 19 servings. Each serving is 28 grams or one level scoop.

You can also order unflavored in a larger serving size of 81 servings, bringing the total cost down to $0.89 per serving. 

The Creamy Chocolate and Creamy Vanilla flavors are a little bit more expensive, costing $1.03 to $1.30 per serving, though the product is frequently on sale and is sold at many different retailers at varying prices. 


NOW Sports Whey Protein Isolate has 25 grams of protein per serving, at only 110 calories for the unflavored protein, and 120 calories for Creamy Chocolate or Creamy Vanilla, earning it a 5-out-of-5-star rating. 

Whey protein isolate is whey protein that’s had most of the fat and lactose removed, resulting in faster and easier digestion. NOW Sports Whey Protein Isolate even earned a spot in our guide to the best protein powder for sensitive stomachs, though our ratings may change with future product testing.

The unflavored version only contains two ingredients, whey protein isolate and sunflower lecithin, with no other additives However, because NOW also makes food products, they do warn that the protein is manufactured in a GMP facility that processes other allergens, like yeast, gluten, soy, shellfish, and others. 

The Creamy Chocolate and Vanilla flavors also contain xantham gum, cocoa, xylitol, organic stevia leaf, and sea salt. Interestingly, the chocolate also contains 1.3 milligrams of iron, which is 8% of the recommended daily value. 

Even though the tub of protein mentions BCAAs on the front, which are branched-chain amino acids, there are no added BCAAs in this formula. BCAAs are three essential amino acids, l-valine, l-leucine, and l-isoleucine that are found in all whey proteins, so I’m not sure why they mention the BCAAs at all if they aren’t adding extra. From what I can tell, this has the typical amino acid profile you’d find in any whey isolate.

With this simple ingredient list, NOW Sports Whey Isolate is high in protein and low in excess calories from carbs and fats, making it a useful option for those on a calorie-restricted diet.

Taste and Solubility 

When it comes to taste, we give this a 4 out of 5. To be fair, Lauren only tried the unflavored edition, but she didn’t enjoy the taste, saying, “There’s definitely a whey taste, which is not that good. This is certainly not gag-worthy but I did mix this with water to get the full non-flavored effect. This would actually be pretty good with a sports drink, or in a smoothie.”

Other reviewers love the flavored options, but we haven’t tried those ourselves. Many customers report using the unflavored protein in other creative ways, like baking it into various recipes to add more protein.

RELATED: How to Use Protein Powder

Solubility earned a 5 out of 5, as it blended perfectly with no clumping, and it wasn’t too thick or unpleasant to drink. 

Side Effects

Lauren didn’t experience any side effects (aside from the weird taste of unflavored whey protein), so we scored this a 5 out of 5. 

If you’re sensitive to dairy you may need to avoid this product, but whey isolates are often very easy to digest as they’ve had most of the lactose removed. Several user reviews specifically mentioned that switching to this product eliminated the gas and bloating they experienced from other types of protein powder. 

Third-Party Testing 

For third-party testing, NOW Sports Whey Isolate earns a 5 out of 5 score. 

NOW does extensive testing on all of its formulas, completing over 19,000 tests and analyses each month at its in-house lab. That may not be true third-party testing but NOW does list the many credentials and certifications the brand has earned.

NOW has received ISO/IEC 17025:2017 accreditation from the American Association for Laboratory Accreditation (A2LA) for both the analytical and microbiological laboratories. They are also Non-GMO Project Verified, GMP certified by Intertek, and Informed-Sport tested to ensure there are no banned substances.

Bottom Line

Myprotein Impact Whey Protein provides 22 grams of protein per serving in a variety of flavors. However, it may not be a great choice for those with gluten sensitivity or other allergies due to the lack of clear ingredient labels on the product pages.

Customer Experience 

Overall, the customer experience is excellent when ordering from NOW Foods. They have a customer support phone number, or you can submit a form through their website. 

New, unopened items may be returned within 30 days, but you need to pay for your return shipping. Other retailers, like Amazon, often have better return policies and don’t charge for return shipping.

Ordering NOW Sports Whey Protein Isolate

When you order directly from NOW, orders that are $50 or more are eligible for free shipping in the United States, though you’ll need to pay an extra $6.95 if you live in Hawaii or Alaska. Other retailers may provide free shipping regardless of where you live. 

Customer Reviews

Customers also had similar comments about the unflavored option, saying it worked well but didn’t have the best flavor. Most users had good things to say about the Creamy Chocolate and Vanilla options but reported somewhat of an aftertaste from the sweeteners used.

Final Verdict of Our NOW Sports Whey Protein Isolate Review

NOW Sports Whey Protein Isolate is a high-quality, affordable protein powder that packs in 25 grams of protein for less than 120 calories per serving, and it’s very affordable compared to many other options on the market. 

It’s only available in three flavors, including unflavored, but for the price per serving and protein content, it’s hard to beat this protein powder. This is a great choice for anyone looking for a high-quality protein source on a budget and isn’t too picky about the flavor choices. 

  • NOW Sports Whey Protein Isolate has a great formulation that’s high in protein, low in total carbohydrates, and easy to digest, making it a great choice for a post-workout protein shake.
  • The flavor selection is quite small compared to most competitors, and the unflavored option isn’t very pleasant to consume alone.

NOW Sports Whey Protein Isolate: FAQ

Is whey isolate as good as whey protein?

Whey isolate may have a slightly higher amount of protein per serving, as some of the excess fats and lactose have been removed for faster and easier digestion. Both forms are rich in beneficial amino acids from protein, as well as important minerals like calcium and potassium. 

Is it okay to drink whey isolate every day?

Yes. Those who have sensitivities to dairy should avoid whey protein isolate altogether, but for everyone else, whey protein isolate is a useful tool to help you reach your daily protein goals. 

Who should not take whey isolate?

Those who are lactose intolerant, or have any problems with dairy, should probably avoid whey protein isolate and use a plant-based protein powder instead. 

Should I buy normal whey or whey isolate?

The protein in both types of whey is the same, and the primary difference is the extra processing in whey isolate that removes fat and lactose. Because of this, whey protein isolate typically has fewer calories per serving and could be a better choice for anyone following a weight reduction plan.

If you like throwing your weight down like any good meathead should, you’re probably pretty familiar with bumper plates. I’ve been testing all kinds of bumper plates over the years, such as the Rogue Fitness US MIL Spec Crumb Bumper Plates, American Barbell Urethane Bumper Plates, and REP Fitness Sport Bumper Plates.I’ve been impressed with the Fringe Sport Bumper Plates in the past so I was eager to deliver a Fringe Sport MilSpec Bumper Plates review. There are a lot of particulars I look for when reviewing a bumper plate—it’s about more than just bounce or aesthetics. I also look at the warranty, price, material, and scale on the Shore Durometer.Why You Should Trust UsI’ve tested over 70 different bumper plates and have even written an article about thebest bumper plates. (I also wrote one on thebest weight plates overall if you’re more of an iron-slinging dude.)
