This is important in a product designed for people in calorific deficits, as the nature of dieting can increase the chances of deficiencies. Take two rounded scoops (55g total) with 200-300ml of water or skimmed milk. Shake or blend for 30 seconds. Take 1-3 servings per day. Who Takes It? This formula contains Tolerase™ L, an active lactase that turns lactose into galactose and glucose. It has been specially developed and patented for use in sports and dietary supplements for lactose-intolerant people to allow them to enjoy these and other dairy products.

This is provided by the extraneous part of the whey concentrate (a mix of milk sugars and fats), and the addition of sunflower oil as a powder. A great source of omega 6 fatty acids, sunflower oil contains healthy, unsaturated fats, and has been shown to reduce LDL (bad) cholesterol, boost HDL cholesterol and reduce risk of heart disease.

USN uses current, up-to-date, peer-reviewed nutritional research throughout the development of our products and continue to employ the latest manufacturing protocols. USN manufactures its products according to stringent GMP and BRCGS regulations (where applicable) and, therefore, takes proactive steps to ensure that our products are safe and effective. As part of this system, we ensure that the ingredients used in USN products: The use of soy protein here is probably to help bump up the protein content due the low-grade whey concentrate and other ingredients that pad the protein out. e.g the fibre content. Calcium caseinate A complex carbohydrate with a lower GI than maltodextrin – rice hits around the 70 mark on the glycemic index, but as a processed starch it’s likely to be higher than this.

This high-quality protein allows you to reach your goals and put your all into exercise.

Whey protein is cheaper to produce than its more refined cousins, isolates and hydrolysates. Concentrate typically achieves 35-80% protein by weight, USN offers us 46%, which is on the low side. Especially as more and more well-known brands are producing whey concentrate-based shakes that hit the high end of the concentrate percentage protein range. Similar but inferior to micellar casein, it’s cheaper and has just as much protein by weight. Calcium caseinate is produced by altering the pH of milk to be more acidic using chemicals and making the casein insoluble. When separated, the casein is combined with calcium hydroxide to form calcium caseinate. During this process the proteins are well and truly denatured, making them less bioavailable and even slower to absorb than micellar casein. I’d love to have seen a blend using more micellar casein instead of this. A big shame is that there is no individual breakdown of how much of each protein is in USN Diet Fuel Ultra Lean. But, at the 46.1g of protein per 100g, the majority is probably from the low-refined whey concentrate.

We can’t compare the doses unfortunately as none are included. But I’d go out on a limb and say that 2.4g is far more than in USN Diet Fuel Ultra Lean. FibreSimilar to its whey counterpart, soy protein isolate achieves no less than 90% protein content by weight. Soy protein has been seen to aid in weight loss and protect muscle mass just as effectively as whey protein. A fruit that’s known to enhance the flavour experience of different foods, garcinia cambogia has collected notoriety for being a superfood fat burner. However, there is little to no evidence to suggest this. The only positive study was in conjunction with a calorie deficit in overweight individuals where a slight increase was noticed. The dose for this… 2.4g garcinia cambogia daily. Overall USN Diet Fuel Ultra Lean has all the hallmarks of a weight loss shake; it just doesn’t offer anything we haven’t seen before. There has been some effort to reduce the GI of the carbs by using rice starch and adding fibre to the mix, but the sunflower oil content is negligible in the bigger picture.
