Enjoy Healthy Whey Protein with Quality You Can Trust!

"The best quality whey protein powder I've found is the Fat Flush Whey Protein from UNI KEY..."
-Nan Kathryn Fuchs, PhD, Editor, Women's Health Letter

Our Fat Flush Whey Protein powder is the perfect protein supplement to support weight loss or a weight management program, lean muscle development, high energy levels, immune health, and the anti-aging process.*

With 20 grams of healthy whey protein per serving, you can enjoy delicious, satisfying smoothies as a complete breakfast, pre or post-workout boost or meal replacement.

Fat Flush Whey Protein is 100% natural, hormone free, pesticide free and chemical free. It contains non-denatured whey concentrate sourced from New Zealand.

Non-denatured whey protein powder is unheated to preserve fragile whey protein structure that contains glycomacropeptides, rich in branched chain amino acids, which act as natural appetite suppressants.

It also contains naturally-occurring healing substances, such as immune-enhancing immunoglobulins and lactoferrin, an iron modulator. Healthy whey protein has been clinically demonstrated to elevate glutathione levels to act as a potent free radical scavenger, relieve fatigue and facilitate muscle recovery.*

A2 Milk Protein

The cow's milk used to produce the whey concentrate for our non-GMO whey protein powder contains the highly sought-after non-mutated A2 beta-casein (milk protein). A1 beta-casein, found in most cow's milk from North America, may be linked to digestive problems, cardiovascular concerns and diabetes. In addition to being easier to digest, A2 protein also contains the amino acid proline which fights aging by supporting collagen.

Tested for Heavy Metals

We are confident in the quality of our whey protein powder and each batch is tested for heavy metals including lead, arsenic, cadmium and mercury.

Contains NO: GMOs, hormones, gluten, egg, soy, corn, added sugars, artificial sweeteners, artificial colors, artificial flavors, preservatives, pesticide residues, or synthetic fillers.

Sweetened with Stevia and inulin, virtually zero on the glycemic index. Stevia is a natural herbal sweetener, and inulin is a prebiotic that helps to support a balanced of intestinal flora for overall GI tract health.*

The lactose content for Fat Flush Whey Protein powder is below the level that generally causes problems for individuals who are lactose intolerant.

Our Chocolate Whey has been discontinued. For the same flavor, simply add unsweetened cocoa powder or cacao to our Vanilla Whey!


Use one (1) scoop per smoothie (scoop included).

Love the product

Love my UniKey whey protein. Have had various other products in the past but this whey protein taste the best and always remains powdery and does not clump up. I use it in many forms - smoothies, I sprinkle it over fruit to get additional protein and the flavor is phenomenal. Quality is superb that is why I subscribe this product and get it automatically shipped to me. Shipment is wonderful too - with std rate I get their products the very next day.

Doesn't hurt my stomach like other whey proteins do

I love that this whey protein is made with milk from A-2 cows. I'm extremely lactose intolerant but this whey doesn't bother me at all!! It also taste great! Thank you UNI KEY!

Fat Flush Whey Protein

I use the product - it’s extra protein to keep my diabetes in check. Just wish you still had it in chocolate!


UNI KEY Health

Hi Nancy, Thanks for your great review! Unfortunately, chocolate just wasn't a big seller. You can still get the chocolate flavor however by adding 1 tablespoon of cocao powder to your smoothie. In good health, UNI KEY Staff

I just love this protein powder. I put it in my oatmeal and make healthy shakes and also just drink it with almond milk. It’s my favorite protein powder!

Totally agree with Nan Fuchs….

That “this is the best whey protein I have found”. I have tried a number of different whey proteins including goat milk whey and none of them were digestible for me; I could tell because they all bother my stomach. Not so with this whey protein and now after reading your blog post I know why! Great to understand more about those factors of A2 milk proteins. This is a great tasting whey protein also. I like it in my FF smoothies.
