The Company Behind MET-Rx Big 100

MET-Rx is a company that has been around for over 20 years. Dr Scott Connelly founded it to help sick patients maintain muscle mass while staying in their hospital beds. The products seemed to work efficiently for the first five years and Dr Connelly became famous.

His company received scrutiny when MET-Rx research claims were found to be fake. Nevertheless, Dr. Connelly pressed on, and his MET-Rx supplements became popular.

The company began to change when he sold it in 2000 to the Rexall Sundown Incorporation. Rexall Sundown’s owners decided MET-Rx could be beneficial to more than just hospital patients. Over the years, the company transformed into a fitness-focused business that targets the bodybuilding and athletic industries.

Met-Rx began sponsoring professional athletes such as weightlifters and football players in the early 2000s, which helped the company gain a lot of popularity. MET-Rx is still in California and Nature’s Bounty Co. currently owns it. They specialize in weight loss supplements, protein shakes, powders, and meal replacement products. MET-Rx sells over $100 million in products every year.

The marketing team targets various age groups, from young to old, while shipping its products domestically and internationally. The most popular areas where MET-Rx products sell well include South America, Africa, Asia, Australia, the Middle East, Mexico, Canada, and the Caribbean.

Ingredients

MET-Rx Big 100 Ingredients

MET-Rx Big 100 contains several ingredients, including:

  • L-glutamine

  • Soy protein isolate
  • Sugar alcohols

metrx big 100 wheat fiber

  • Wheat fiber
  • Whey protein concentrate
  • Whey protein isolate
  • Vitamins
  • Minerals

Surprisingly, many of the ingredients in this product are natural. This convinces nutritionists that MET-Rx took the time to create a meal replacement bar that will benefit people with decreasing hunger without jeopardizing overall health.

However, due to the amount of sugar in MET-Rx Big 100 bars, nutritionists and strict dieters have recommended other options.

Side Effects

MET-Rx Big 100 Side Effects

So what kind of side effects should we watch out for? The MET-Rx Big 100 bars do not come with a long list.

Possible side effects from the bars are not unique, and altering eating habits will always cause mild discomfort. These bars have an ingredient called sugar alcohol, which can cause irregular digestion patterns. Irregular digestion can lead to flatulence, stomachaches, nausea, and increased bowel movements.

Benefits

MET-Rx Big 100 Benefits

The claimed benefits of eating the MET-Rx Big 100 bars range from fitness benefits to health improvements. MET-Rx claims these bars will not only help reduce hunger throughout the day but that they will also boost energy and reduce the overall recovery time between workouts.

The long-term benefits that it allegedly gives are lean muscle growth, weight loss, and a healthy, well-sculpted body. The combination of natural ingredients and high-quality protein is to help an individual reach their fitness goals and create a noticeable change in their physique.

MET-Rx is supposedly beneficial to customers who are physically active on a regular basis, and also to people who are occasionally active as long as they are on a relatively healthy diet.

metrx big 100 benefits

The company claims to produce higher sports performance results compared to other fitness products.

Along with these benefits, MET-Rx states that its products are extremely easy and convenient to use.

The MET-Rx website states that its products are advantageous for women who want to improve their physique and it assures users that they will help increase metabolism if you take them daily when exercising.

Not only is the MET-Rx Big 100 ideal for young customers, but the company also states that nutrients in the product will benefit the elderly, who are often susceptible to losing muscle mass.

Does MET-Rx Big 100 Work?

The MET-Rx official website provides statements regarding the amount of research behind their various supplements and products.

They supposedly have 20 years of research supporting the quality and efficacy of the fitness products they offer.

Although the MET-Rx website contains testing results for the amino acid in Metamyosyn protein, these meal replacement bars do not have any direct clinical or medical proof supporting the company’s claims of muscle growth, weight loss, or even decreased hunger.

The MET-Rx official website contains many claimed benefits about MET-Rx Big 100 meal replacement bars, but those claims also come with a condition.

The company states that users should constantly be working out on a regular basis while taking the product.

They also state that results will come if the user stays on a regulated diet and does not consume a lot of unhealthy foods while eating the bars. That being said, doctors and fitness connoisseurs have concluded that there is no clear proof that the bars will produce results on its own. In fact, they believe that it might be a good idea to look at cheaper supplements or weight loss alternatives.

cheaper alternative to metrx big 100

There is no evidence to back up Met-Rx’s claims that the products can stimulate weight loss or even enhance muscle growth. If using the bar for weight gain and muscle growth, the high sugar and high fat may not be much of a problem. However, if using the bar as a meal replacement, the sugar and high fat content are not exactly healthy for the body.

According to doctors, every person needs to have at least some carbohydrates to recover after a workout. But those carbs certainly don’t need to be sugars and not 29g of them.

MET-Rx Big 100 Reviews

Customers have given MET-Rx Big 100 a variety of reviews concerning the product’s quality, taste, prices, and efficiency.

The MET Rx Big 100 colossal bar reviews typically give the product a high rating overall, with some negative comments.

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.

Along with the taste, the quality of the bars has also received favorable reviews. One thing customers have complained about is the high cost of the product and the varying results for those trying to lose weight.

Customers were not impressed with how much sugar is in the bar, especially those attempting to lose weight.

When asking how healthy MET Rx Big 100 is, one must take into account the negative nutrition facts as well as the positive ones.

Directions

Directions For MET-Rx Big 100

You’re meant to eat MET-Rx Big 100 bars immediately after a workout if you’re trying to build muscle. You can also eat them in place of or with a regular meal if trying to lose weight.

The bars are not to replace every meal of the day and you should only eat them every three to four hours.

Along with consuming these meal replacement bars on a regular basis, MET-Rx states that users should be working out each day to balance exercise with a well-rounded diet.

This combination is to increase the flow of nutrients into the body to benefit the user’s health in the long run. Users should also note that MET-Rx Big 100 is mainly with soy protein isolate. If they have any soy related allergies, it is best that they contact their physician before purchasing the product.

MET-Rx Big 100 and Weight Gain

metrx big 100 and weight gain

The answer will depend on the customer’s goals.

If someone is trying to lose weight or reduce hunger, these meal replacement bars may be a good option to consider. They might help an individual reach their weight loss goals if they are taking in fewer calories and carbohydrates than they would on a regular basis.

You should also note that consuming the bars alone will not necessarily increase weight loss, as the MET-Rx website states. Customers need to work out on a regular basis to stimulate fat burn. You should eat the bars to reduce hunger instead of unhealthy foods that will simply cause you to gain weight.

Another thing to keep in mind is that people who participate in physical activity on a regular basis will more likely lose more weight compared to people who do not. Therefore, users need to realize that MET-Rx meal replacement bars are not necessarily a key factor in weight loss, habitual physical activity is. This means that other weight loss options should remain in consideration.

Eating healthy products while working out consistently will help burn fat; which means that at some point, a meal replacement bar may be simply unnecessary.

What Users Are Saying

“Met-Rx has been a great company for a long time. I love the bars which are a great alternative when on the go.”

“I gave the MET-Rx bars a chance and after eating about half of one I had to stop. The bars were incredibly sweet and after checking the label I noticed there was 28G of sugar PER BAR! The title of the bars say “healthy meal replacement” but pretty much no instance would I consider eating a bar with lots of preservatives and 28G of sugar a “healthy” meal.”

“These MET-Rx Big 100 bars are big. Each of them could really replace a meal, with 32 ounce of protein, equivalent to 6 and a half eggs. It also has a good amount of fiber.”

Bottom Line

The Bottom Line – Does Met-Rx Big 100 Work?

Are you unwrapping a Met-Rx Big 100 bar? Well, we like that that some positive customer comments are on the web and the company has been in business for years, but we’re sceptical about this one because there are no clinical studies supporting the strength-building claims. We also have reservations due to customers talking about bad taste and a high price tag.

If you want to improve your strength gains, our suggestion is a program that teaches you how to eat right and is backed by published clinical studies.

Among the best programs we’ve seen this year is one called Noom. The quality of the tools provided is unprecedented. There is human one-on-one coaching, food logging, an extensive food database and more. Plus, science says it works because people lose weight and keep it off.

The company that’s behind Noom is so confident in their weight-loss app, they’re providing customers with a 14-day trial.
