The term meal replacement has been around for many years. However, with the major advances in understanding human health and food nutrition, Diet Meal Replacement Extreme is now more akin to a nutritionally complete meal.

They are both great products, but the Extreme version is enhanced in a number of ways vs the standard version. Firstly, it has a higher protein content and also a lower calories per serving.
Secondly, it has a wide range of value-add ingredients such as CLA and Green Tea Extract that aren’t present in the standard version.
Finally, the Extreme version has an incredible selection of flavours for you to choose from, including some of our insane-tasting Premium Flavours.
Absolutely! Just think of it as a normal daily meal. As always, check the label of any supplement you are looking to take for allergies and intolerances.

Meal replacements contain a balanced ratio of protein, fibre, fats, carbs and micronutrients, and are being designed to be nutritionally complete. A protein shake usually contains a very high protein content and is primarily made from pure protein sources, and then enhanced quite often with additional active ingredients to support specific body or performance goals.
It’s suitable for vegetarians, but unfortunately not for vegans. However, we have developed a vegan-friendly version called Vegan Diet Meal Replacement Extreme, which is ideal for vegans or anyone wanting to reduce their dairy intake.
This meal replacement shakes contains milk, soy and cereals containing gluten in all flavours. However, it is GMO Free, Aspartame Free, Egg Free and Palm Oil Free.
