Diet Whey Complex Extreme

Diet Whey Complex Extreme contains a Tri-Protein Blend of Diet Whey Isolate 97, Whey Protein Isolate 90 and Whey Protein 80. This ground-breaking formula also includes premium grade amino acids, vitamins and minerals, plus microencapsulated CLA, the soluble fibre Konjac Glucomannan and our own unique Tri-Tea Blend.

Diet Whey Complex Extreme Macronutrient Profile

The actual macronutrient profile of Diet Whey Complex Extreme has been purposely designed to contain very little carbohydrates and fat, yet equally be very high in lean protein. By using only the finest premium grade ingredients, each serving of Diet Whey Complex Extreme contains less than 2 grams of carbohydrates and 22g of protein.

Diet Whey Complex Extreme Added Active Ingredients

To help you better understand the comprehensive and complex ingredient profile of the Diet Whey Complex Extreme, the TPW™ team have listed the individual ingredients below:

  • Clarinol® CLA - is a special kind of fatty acid that involves microencapsulation technology. Each individual CLA particle is microencapsulated with a water soluble coating that helps control the release of the active ingredient, which helps improve its stability and function. More importantly for many people, it removes the unpalatable taste that CLA is known for.
  • TPW™ Tri-Tea Blend - contains a unique blend of Matcha Green Tea, White Tea and Black Tea. Each is known for its impressive content of antioxidants.
  • L-Carnitine - is an amino compound found in tissues that use fatty acids as the main fuel. It’s one of the best-selling single amino acid supplements in the diet industry.
  • Konjac Glucomannan - is a form of water soluble fibre which has been found in studies to contribute to fat loss. This is because Konjac Glucomannan can help increase feelings of satiety and being full which in turn prevents overeating and unhealthy snacking.
  • TPW™ Vitamin Blend- is synergistic blend of vitamins and minerals shown to contribute to normal energy-yielding metabolism, normal functioning of the nervous system and macronutrient metabolism.

It tastes grate easy to drink and it help. I don’t train to often and my diet is not the best but I’m getting weight loss slowly but surely

I ordered this product about a month ago in "Banana Smooth". The powder mixes perfectly and is so smooth to drink.
I have been using the shake, along with the Green Tea Capsules and I've lost 0.8kg of fat each week for the last 4 weeks. This is the most amount of fat I've lost in one week compared to every other dieting method I've ever used. Of course it has to be used with a calorie controlled diet and a good exercise plan but still.

My only other comment is that I don't like the Banana taste. Yes, I did buy Banana but only for the reason that I thought it would be the least disgusting out of the flavours. It tastes just like a Banana milkshake when used with Almond or normal cows milk. It's just that I'm not a huge fan of Banana. Can we have some more flavours please? I'd personally love it in the Vanilla flavour

Its a very good product!
I usually use it in the evening after an exercise and combine it with a Diet Meal Replacement (that I take in the morning). Together with a healthy lunch I never feel hungry. It's tasty (I tried Chocolate Silk and banana by now) and I can't stop recommending it to my friends. Excellent!
