Overall Quality

Optimum Nutrition is very well known around the world for being one of the best manufacturers of sports and bodybuilding supplements, especially in the protein powder arena.

With this in mind, it should come as no surprise that Pro Complex is a truly world-class protein powder.

This product certainly isn’t the cheapest one of its kind; however, you absolutely do get what you pay for, so if you are looking for a high-grade protein supplement then you are definitely in the right place.


Most of us have used protein powder in the past so there isn’t a whole lot to say on the efficiency of using this product.

It is worth mentioning, however, that the refined proteins in Optimum Nutrition Pro Complex mix wonderfully into water or milk, leaving you with a shake that is delicious and very easy on the stomach.

Taste / Composition / Mixability

There is a tendency with some highly refined proteins such as isolates and hydrolysates to lack flavor and texture.

Unfortunately, this leads some manufacturers to add in extra, arguably less healthy ingredients such as creamers and emulsifiers.

This doesn’t appear to be the case with Optimum Nutrition Pro Complex, and you can easily tell that the manufacturer has made a great deal of effort to produce a shake that is well balanced in terms of taste, consistency, and overall digestibility.

As we just mentioned above, Optimum Nutrition Pro Complex mixes very easily even by being shaken or stirred, and the end result is a delicious protein drink that you can adjust in terms of consistency by adding more or less water depending on your preferences.

Is it Worth the Money?

If you are an absolute beginner your money would probably be better off spent on a cheaper protein powder so that you can allocate some of your budget to other basic supplements such as creatine monohydrate and a multivitamin.

On the other hand, if you are slightly more experienced or you are training hard for a competition then Optimum Nutrition Pro Complex checking out.

As mentioned earlier, this is a premium protein powder supplement, and one that is probably not suitable for those of you are operating on an extremely tight budget.

Nevertheless, the premium on this product is certainly justified, and the Optimum Nutrition Pro Complex definitely offers decent value for money.

Final Thoughts

Optimum Nutrition Pro Complex is a tasty and highly effective protein blend that is very easy to digest and provides the added benefit of a range of vitamins and minerals.
