Product Features

Although MRX1 provides 45g of protein per serving, the supplement is not a protein powder. In fact, MRX1 is a meal replacement shake. The reason the supplement is a meal replacement centers on the amount of calories per serving. One serving, two scoops, equals 310 calories. The company recommends a minimum of four scoops for the average size man. In essence, you could be consuming 620 calories. Typically, if you are attempting to lose weight, your meal could not be this high in calories.

As we reviewed the ingredient list, we noticed the carbohydrate count. Each serving is 26g of carbohydrates, the majority from sugars. There is a long list of sugars included in the supplements. Regardless of the protein in the supplement, the carbohydrates are too high. This excludes dieters on a restrictive dieting plan.

The price is another concern. On the official website, MRX1 retails for approximately $60. This is twice as much as similar products on the market. This is a large sum to pay for a supplement with no guarantee of effectiveness. We noticed there are no links to clinical trials or scientific research.

Dieters know the proven benefits of protein powders and supplements. When used in conjunction with a balanced diet and exercise, supplements such as MRX1 are basically effective. The concern centers on the lack of evidence the supplement works. There are no links to clinical trials, scientific research or evidence of customer testimonials. The only proof relating to the effectiveness comes from the company.
