About Jay Robb Whey Isolate Protein

This product is made from milk, yet the lactose has been removed to reduce the risk of allergic reactions. The milk is derived from grass-fed cows, meaning it is free of animal growth hormones. It’s also non-GMO and contains none of the typical ingredients that cause allergic reactions.

Made with Stevia for added sweetness, the whey protein is free of any and all artificial sweeteners, flavorings, and colorings. It contains no casein protein or MSG, is gluten-free, and has no sugar or aspartame. Basically, it’s as natural and healthy as the manufacturer could make it.

In terms of protein content, it delivers the industry-average 25 grams per serving. Each serving contains just 1 gram of carbohydrates, providing a small quantity of energy to help you get through your workout. It contains no BCAAs, but it’s simply a source of whey protein–ideal for a pre-workout protein smoothie.

The protein is produced using the “cold filtration” process, ensuring maximum amino acid content in the protein powder.

Pros of Jay Robb Whey Isolate Protein

Here are a few of the good things users have had to say about Jay Robb Whey Isolate Protein:

  • All natural: With this protein powder, you get ONLY natural ingredients. It’s made entirely from grass-fed cow’s milk, with only natural Stevia added for extra sweetness. If your goal is to find an unprocessed, untreated product, this is definitely one to consider. It’s not USDA Certified Organic, but it’s as close as it gets!
  • Decent flavors: Reviewers are divided over the flavors of the protein powders. Most agree that the “Orange Creamsicle” flavor and vanilla flavors are the best, though the Pineapple-Coconut flavor mixes well with chocolate milk. It’s not the best-tasting protein powder around, but considering that it’s all-natural, it’s a pretty good option. Best of all, there is little to no after-taste–a problem common among whey protein powders.
  • Mixes well: You will need to use a blender or Blender Bottle to get a really good mixture, but the protein powder is ideal for mixing with milk, coconut milk, or even water. It doesn’t produce too much froth, but it is rich and creamy. Definitely a good option for those who prefer a subtler addition to their smoothies.
  • Less sugar: Unlike most protein powders, this one contains almost no sugar–just 1 gram of carbs per serving. This means that it’s less likely to cause weight gain when consumed as a midday snack. It’s not as useful for restoring energy after an intense workout, but you’ll find that it makes a good addition to your healthy, low-calorie, low-sugar diet. The Stevia will add plenty of sweetness without adding sugar.

Cons of Jay Robb Whey Isolate Protein

As with any product, there are a few negative things people had to say about Jay Robb Whey Isolate Protein:

  • High cost: At $38 (For the latest prices and discounts, check here) for a 1.5 pound bag, this is one of the priciest protein powders around. Compare this to Optimum Nutrition Gold (one of the highest-rated protein powders), which costs just $58 for 5 pounds. Jay Robb Whey Isolate is definitely a protein only recommended for those who can afford to pay extra for quality.
  • Poor packaging quality: Unlike other protein powders that come in a can or tub, this one comes in a plastic bag with a “Zip-loc” closure. The closure is easily clogged with the thick protein powder, making it hard to close. The packaging is a bit cheap, and it doesn’t look or feel like a high-quality product like other protein powders.
  • Risk of allergic reactions: The product claims to be lactose-free, but it contains eggs and Stevia–both of which are known to cause allergic reactions. There is also a risk of cross-contamination with other allergens (such as soy, wheat, dairy, tree nuts, fish, peanuts, and shellfish) thanks to the fact that it is processed in the same facility as these other foods.
  • Strong Stevia aftertaste: If you’ve ever tasted Stevia, you’ll be familiar with the aftertaste it leaves in your mouth. Some reviewers called the aftertaste “soapy”. In many cases, the Stevia aftertaste was so strong that it made it hard for reviewers to enjoy the regular flavors.

Other Options to Consider – Alternatives to Jay Robb

If you’re not convinced that Jay Robb Whey Isolate Protein is the right product for you, here are a few good options to consider:

Promix 100% Grass-Fed Whey: This is another option for those who ONLY want whey protein made from grass-fed cow’s milk (see full review here). It doesn’t offer the same high nutritional value as Jay Robb Whey Protein Isolate (only 20 grams of protein per serving), but it gives you more carbs and fats–making it a better post-workout source of protein.

It is guaranteed to be free of soy, gluten, and nuts, though not lactose-free. At $80 (For the latest prices and discounts, check here) for 5 pounds of high quality whey protein, it’s a much more affordable alternative.

Cellucor Cor-Performance Whey Isolate: This is one of the highest-rated whey protein powders around! The nutritional profile is better than the Jay Robb Whey Protein Isolate–with 25 grams of protein and 5.5 grams of BCAAs.

It even contains digestive enzymes to make the whey protein easier on your digestive system. At the price–$48 (For the latest prices and discounts, check here) for 4 pounds–it’s definitely an affordable choice, and a high quality one at that!

BulkSupplements CLEAN Whey: This is an excellent protein powder for those who want all-natural whey isolates (my review here). Made in the USA, it’s clean, pure, and free of preservatives and fillers. It is a third-party lab tested for purity and is a top-rated product.

It is 90% whey protein, and though it has minimal flavor, it mixes beautifully with just about any liquid. It’s a product for a savvy consumer. (For the latest prices and discounts, check here)

Final Thoughts

While Jay Robb Whey Isolate Protein isn’t perfect, it offers a lot of benefits: all-natural whey protein, non-GMO ingredients, and a high dose of amino acids. It’s a tad pricey, but it’s definitely a good option for those who want clean whey protein made from grass-fed cow’s milk. If you are looking to buy in bulk, I’d check out this listing first.
