Expert Reviews

What reviewers liked

Extremely high amount of protein at 30 grams per bar,which should satisfy your hunger. Mixes fast and slow acting proteins, which is deal for athletes.
The majority of users have rated the meal replacement bar positively for its remarkably good taste. Many protein bar companies fail in this category, which is why MET-Rx stands out in this aspect.
If your goal is to bulk up and add muscle, the high calories and carbs, combined with 30g of protein per serving will certainly make it easier. No other protein bar we've seen has more calories.
No observed side effects.
Formulated with high nutrition to keep up with high level athletes.
General creaminess that is not found in most meal replacement bars.
If there’s one thing we want to touch upon in this Met-Rx Big 100 Colossal bars review, it’s that these bars taste fantastic. One huge complaint that people have about protein bars is that they often have a texture that can only be described as “chalky”. The Big 100 bars not only avoid this problem, but impress us with a chewy texture.
When I began eating it, I had no problem eating the entire bar very quickly. I have a very small appetite and for me, even eating a large protein bar is a lot of calories for me to consume.

What reviewers didn't like

A little pricey per bar versus some others. Has 410 calories per bar, which is high.
One thing customers have complained about is the high cost of the product and the varying results for those trying to lose weight.
In terms of price, they're slightly more expensive than most protein bars.
The sugar slightly high.
Melts more easily
Always creates the feeling of a full stomach, which does not suit some athletes after a workout
Met-Rx Big 100 Colossal bars have one side effect that you should keep in mind. Every bar contains sugar alcohols, which may cause gastrointestinal discomfort for some people.
