Grass-fed whey protein isolate praised for excellent taste and clean ingredients. Customers said it "tastes delicious" and mixes easily without grittiness. Many loyal shoppers use it daily in smoothies, coffee, and baking. However, one customer reported a batch tasting like dish soap, and another noted potential recipe changes affecting consistency and clumping.

  • Cleanest ingredients and it taste tremendous. Never get sick of it even after years
  • Mixes easily with water and has a natural vanilla flavor with perfect sweetness
  • I have never had anything that tastes so good and is so healthy for me

Vanilla / 6 lb
Taste like dish soap

I would love to give this 5 stars but this batch taste like dish soap and is very sudsy every time I shake it up. I have used this product for years. First purchased from my chiropractor and then started ordering from the company. Waiting to hear back from the manager on how we can fix this.

Purely Delicious!!

I love this whey and have used it for many years. It mixes easily with water and has a natural vanilla flavor with a perfect amount of sweetness. This is a high quality product with very few ingredients - not a huge container full of fillers. I highly recommend. Especially if you’re into fitness and recovery.

Great flavor and no aftertaste bite!

Great product

great product because it is grass fed protein and includes large amounts of bcaa's (the building blocks for retaining and producing muscle) especially in older folks.This is a easy product to add to your mornings regiment without buying a alot of supp. and doing it yourself. But is not very affordable and can get pricey.

Delicious Whey Protein!

BUY IT! We ordered the 1lb of the double chocolate Grass fed whey protein first because we weren't sure if we would like the flavor. Now we order the 3lbs! It's delicious and just the right sweetness. Not overly chocolatey. Mixes really well. We will keep ordering this product. We love ordering from Lifesource because they share our values and have quality products.
