Customers review summary

The Isopure unflavored whey protein powder appeals to customers seeking a clean protein base with no flavor that blends into coffee and smoothies. Its two ingredient formula, strong protein to calorie ratio, and gentle effect on stomachs make it easy to mix into cold drinks or baking. A minority of customers mention a milky taste or occasional clumping in hot liquids, yet most find it a versatile, easy way to boost daily protein.

Under the 'Product Info' warning, it states not to use this product for weight reduction. Why? I thought this would be a great solution to my protein needs for weight loss.

  It's perfectly fine to use this as your protein supplement within a balanced diet, I do- its my favorite powder by far, it mixes well even in just your morning coffee, and I've lost a lot including or in my daily 1200 calories. I think they put that warning on there just to say 'hey, this isnt a meal replacement', because it doesn't include carbs or lipids which you need as well.

Brianna S

  I use this product as a solution to insure I meet my protein needs from exercising and weight reduction. I think the intention of the manufacturer is that it not be used as a replacement meal but instead as a supplement. This is a very clean complete product.

Pamela

  I don't know why they put that on there. You would need to ask them. I don't eat much meat & alergic to soy. So I use it to supplement the lack ofpprotein that I consume.

Claudia S

  I'm not sure why it would state that. It may be a "CYA" thing.

  Hi. The last batch I ordered doesn't expire until 6/2015. It may loose some nutritional value the longer it is opened (exposed to air) but I don't know. It is a great product!

Sharon P

  I've used this alternating between flavors over the course of a couple of months. I've never had an issue with Isopure protein clumping or not mixing well even over time. Hope this helps.

Sara H

  Well the label dating indicates almost 3 years. (But as long as it's sealed, it seems like it should keep much longer without degrading much.)

John

  Hard to say as I use a big scoop everyday. Sorry I couldn't be more helpful. It won't go bad, because you'll use it! It's great stuff.

Laura S

  I drink a shake at least every other day. 1 tub lasts approx 1.5 months for me
