Thermogenic Protein for Weight Loss

Thermowhey has been formulated based on cutting edge scientific literature. Combining the most bioavailable and pure Whey Protein Isolate with Micellar Casein (Milk Protein Isolate), the combinations of proteins in Thermowhey, ensure fats and carbohydrates are minimised. The addition of Casein means absorption is prolonged, which is vital for the feeling of fullness.

Amazing flavours

Thermowhey comes in 6 rich flavours that feel like a treat when really, they're as healthy as can be!

  • Chocolate - a creamy chocolate flavour. Truly a classic.
  • Cookies and Cream - a sweet blend of vanilla and cookies.
  • Strawberry - Thermowhey's fruity flavour.
  • Salted Caramel - the perfect blend of sweet and salt, with oodles of caramel.
  • Rocky Road - amazing combination of marshmallow, chocolate and strawberry.
  • Vanilla - a clean, crisp vanilla and nothing else.

An optimum blend of WPI and Casein

By combining Whey Protein Isolate and Casein, we feel that Thermowhey offers the vital benefits of both proteins, which together are more effective than either protein source in isolation. Thermowhey is more than 83% protein, yet contains less than 1g of fats and carbs per 30g serve. Thermowhey combines 9 key ingredients, Glucommanan Fibre, Forksolin, Sesamin, ALA, Green Tea Extract, Olive Leaf Extract, Cayenne Pepper Extract and Caffeine have been included at doses supported by literature, and should ensure body composition and performance goals are met.

Clinically tested ingredients

The ingredients selected for Thermowhey have all been used in clinical trials and have been included in doses which we deem effective for the purpose. It is important to note that Thermowhey is not simply a fat burning protein with fashionable ingredients, rather a very carefully formulated product which can assist those looking for real body composition changes.

Thermowhey is suitable for both men and women, regardless of body composition goals.
