Prolab Lean Mass Complex Review
Previously Prolab Lean Mass Matrix - Now "Complex"
The Prolab Lean Mass Complex meal replacement powder was originally marketed as the "Lean Mass Matrix". From what I can see, there isn't any difference between the Lean Mass Complex now and the previous Lean Mass Matrix. Same nutritional content, same packaging, just a slightly different name.
I could make a wild guess and say that the "complex" part of the name is for the source of carbohydrates being complex carbohydrates. That, of course, is simply shooting in the dark.
Prolab Lean Mass Complex Nutrition
The Prolab lean mass complex meal replacement is based on a solid 40-40-20 diet plan, which I follow (although not religiously). You can read about my diet and nutrition plan in my rather long multi part diet and nutrition guide here. In short, however, the 40-40-20 diet plan just means that your daily nutrition intake is based on 40% protein, 40% carbs, and 20% fat.
Along with a host of vitamins, minerals, Prolab lean mass complex comes with 40 grams of protein blend, 40 grams of carbohydrate, and 8 grams of fat. The protein blend of fast and slow absorbing proteins which they call "Sustained Release Bioactive Proteins" - these consist of whey protein concentrate, micellar casein, calcium caseinate, and whey protein isolate. The whey protein component are fast absorbing, while the casein proteins are slow digesting.
40 grams of carbohydrates will probably seem on the high end of the scale for many; however, I'd like to point out that although Lean Mass Matrix has 40g of carbs per serving, the sources of carbohydrates is noteworthy. The 40 grams of carbohydrates comes from barley, brown rice, and oat flour. Let's check out the glycemic index of these.
- Barley - 25 GI
- Brown rice - 50 GI
- Oat Flour Porridge - 74 GI
As you can see, the carbohydrates come from low GI foods.

Lean Mass Matrix Taste Test
When it comes to the bottom line, we all want to know how good (or how bad in some cases) a protein supplement or meal replacement tastes. I've tried all 3 flavors: chocolate, vanilla, and cinnamon oatmeal. Overall, I would give lean mass matrix a 8.5/10 for taste.
The chocolate and vanilla flavors were pretty standard... Tasted like, well, chocolate and vanilla. =) Quite pleasant I would have to say. The cinnamon oatmeal is something else. I think this might be one of those flavors that you either like it, or you don't. I happened to like it. It had a pretty pleasant smell as well, just like cinnamon and oatmeal.
The shake was quite thick. This may sound strange, but while drinking it, I almost felt like I was drinking blended up cinnamon oatmeal cereal - not sure if that's a good thing. You may, or may not like this flavor, but give it a shot. I thought it was quite good. Finally, mixing wasn't an issue for all three flavors.
