Bulk Nutrients Best Protein Powder For Weight Loss

Thermowhey has been formulated based on cutting edge scientific literature for those who are after a whey protein powder for weight loss.

Why Thermowhey is the best thermogenic protein powder

Bulk Nutrients’ Thermowhey combines the most bioavailable and pure Whey Protein Isolate with Micellar Casein (Milk Protein Isolate).

This combination of proteins in Thermowhey ensure fats and carbohydrates are minimised, while the addition of Micellar Casein means absorption is prolonged which is vital for the feeling of fullness.

Weight Loss Protein Powder in Amazing Flavours

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

  • Chocolate - a decadent chocolate flavour. Truly a classic.
  • Cookies and Cream - a sweet blend of vanilla and cookies.
  • Strawberry - Thermowhey's fruity flavour, perfect for smoothies.
  • 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.

Thermowhey really is Australia’s best thermogenic protein powder for weight loss.

An optimum blend of WPI and Casein to aid weight loss

By combining Whey Protein Isolate and Micellar Casein, Thermowhey offers the vital benefits of both proteins, which together are more effective than either protein source in isolation.

“Thermoway tastes delish, mixes really well and is reasonably priced. I have it in four flavours (vanilla, rocky road, caramel and chocolate) and holy moly rocky road is next level delish. Tastes amazing with just water. Cannot recommend enough”

While this customer said...

“I ordered the strawberry and the rocky road Thermowhey. Arrived within 2 days. Couldn't wait to try these flavours. Both did not disappoint. The rocky road is just like rocky road! The strawberry is more-ish. Both are great on their own or added to foods. Both powders leave no yucky texture, and no lumps. Highly recommend”

    Great protein - vanilla maple and rocky road are the best flavours in the BN range of products ! Great with water and a good kick start to day.

    Vanilla Thermowhey

    Absolutely love this to add to daily shake

  • 5
    So delicious!!

    I've had the vanilla, vanilla maple, salted caramel and chocolate now. These are definitely the BEST tasting weight-loss shakes around and keep me feeling satisfied and full from breakfast til lunch and then lunch til dinner (when I eat a full, portion controlled meal). I've been on around 1-2kg weight loss a week since starting these shakes where I've failed in everything else before because of the foul tastes or no feeling of fullness. Can not recommend Bulk Nutrients enough!

    Purchased another 1kg pack of Vanilla Maple ThermoWhey, very happy with the flavour and the mixability of the products. One very happy customer that Vanilla Maple flavour is here to stay.
