MET Rx Natural Whey Protein Powder

MET-Rx Natural Whey Protein Powder Review

With a protein combination that includes Whey Protein Concentrate and Whey Protein Isolate, MET-Rx Natural Whey offers you with 23 g of protein, 5 g of carbs, 2 g of fat, and 130 calories per serving.

Over 5.5 grams of essential and non-essential amino acids, including Arginine, Alanine, and the entire range of BCAAs, are included in each 33 g scoop (L-Leucine, L-Isoleucine, L-Valine). Would a ‘all-in-one’ muscle-building protein be greater value for money if it didn’t contain Creatine Monohydrate or L-Glutamine?

We’ll compare MET-Rx Natural Whey to two additional top-rated protein powders: Six Star 100% Whey Protein and Optimum Nutrition Gold Standard in this review. Ingredients, doses, pricing, cost per serving, flavors, and customer comments are all included to assist you in determining whether Natural Whey is the ideal protein for your fitness objectives and budget.

We’ve also included suggestions for the finest Glutamine, Creatine, and pre-workout supplements to use with Natural Whey to help you achieve your goals for strength, lean muscle growth, endurance, and post-workout recovery.

Who Are Met-Rx?

MET Rx Natural Whey Protein Powder

For almost 20 years, MET-Rx has been the market leader in sports nutrition. Protein bars, RTDs, protein powders, multivitamins, amino acids, and creatine have established their name on supplying high-quality supplements. Natural Whey Protein Powder, Creatine 4200, and the MET-Rx Protein Plus bar are among the current bestsellers, each with over 500 positive Amazon ratings.

Meal replacement powders from MET-Rx are also well-known (MRPs). In the earlier edition, you had to combine powder from two canisters, one labeled “base” and the other “plus.” The micellar casein component was eventually eliminated and the product was offered as a single product. One of their most popular products is the MET-Rx meal replacement powder. 3 grams of L-glutamine, 38 grams of Metamyosyn protein, and more than 6 grams of BCAAs are included in each meal.

Met-Rx Natural Whey Ingredients

MET Rx Natural Whey Protein Powder Amino Acid Profile

This might be a good alternative to Optimum Nutrition Gold Standard Whey if you’re on a budget. Except for 1 g less protein, 1 g more fat, and 10 more calories per serving, MET-Rx Natural Whey has a nearly identical macronutrient profile. A 5 pound tub of Natural Whey costs slightly over $43 ($0.64 per serving) at writing this article, whereas a 5 pound container of Gold Standard Whey costs $58 ($0.78 per serving).

When it comes to the micronutrient profile (vitamins and minerals), the salt content (55 mg, 2% DV) is among the lowest we’ve observed in a protein powder, with average cholesterol (40 mg, 13% DV) and calcium levels (109 mg, 11 percent DV).

Protein Blend And BCAAs

The protein mix is made up of whey protein isolate and whey protein concentrate, with the whey isolate helping to keep the carb and fat content low while the whey concentrate keeps the price low.

Natural Whey provides about 5 g of BCAAs (L-leucine 2.4 g, L-isoleucine 1.4 g, L-valine 1.3 g per serving) despite not having a 2:1:1 ratio. The following is a complete list of essential and non-essential amino acids.

Essential Amino Acids (Eaa)

  • Isoleucine 1,417 mg
  • Leucine 2,406 mg
  • Lysine 1,966 mg
  • Methionine 467 mg
  • Phenylalanine 741 mg
  • Histidine 437 mg
  • Isoleucine 1,417 mg
  • Leucine 2,406 mg
  • Lysine 1,966 mg
  • Methionine 467 mg
  • Phenylalanine 741 mg
  • Valine 1,310 mg
  • Threonine 1,509 mg
  • Tryptophan 387 mg

Non Essential Amino Acids (Neaa)

  • Glutamic Acid 3,133 mg
  • Alanine 1,099 mg
  • Arginine 531 mg
  • Aspartic Acid 2,426 mg
  • Cysteine 563 mg
  • Glycine 408 mg
  • Proline 1,356 mg
  • Serine 1,083 mg
  • Tyrosine 681 mg

Cocoa, fructose, 170 mg of stevia extract (sweetener), and soy lecithin for enhanced mixability in water and milk are all stated on the label. MET-Rx Natural Whey does not include acesulfame-potassium, a sugar substitute that is up to 200 times sweeter than table sugar and is deemed safe by the FDA, but there is some debate over its safety.

This product is environmentally friendly in the sense that it does not include artificial chemicals, however that may not be enough for you. The protein in this product is neither non-GMO nor hormone-free. We tend to think of it as more half-way natural since it removes some of the components that make us nervous.

While this is excellent, it does not match the performance of MET-Ultramyosin, Rx’s which is a pure whey isolate. As a result, this product is less effective. We would have considered this product considerably more amazing if it had retained its Ultramyosin origins.

While MET-Rx claims to have kept the lactose level low, the product still contains whey concentrate, which is typically higher in lactose. If you have lactose sensitivity, this product may cause you stomach problems. For this reason, a digestive enzyme like Lactase may have been beneficial, but it wasn’t added.

Sizes And Flavors

Each tub has up to 68 servings with a serving size of 33 grams. This should last 34 days / 1 month if taken at the recommended daily dose of 2 scoops each day.

Each serving was $0.64 at the time of writing this review, which is less expensive than NOW Foods Whey Protein Isolate (about $1.00 per serving). The BCAA ratios are identical in both protein powders, however the MET-Rx protein includes slightly more carbohydrates (+4g) and fat (+1.5g) per serving. Before making a final purchase choice, we always recommend determining the average cost per serving across all sizes.


  • Chocolate
  • Vanilla

Mixability, Taste, And Texture

This product had a pleasant taste in both milk and water, but nothing particularly remarkable. However, achieving a consistent flavor in both milk and water might be difficult, but this product succeeds. The texture was very pleasant, and the powder easily dissolved in both milk and water.

  • Use it in milk For a smooth texture, mix easily with milk.
  • Use it in water For a smooth texture, it mixes readily with water.


MET-Rx Natural Whey is really simple to use. You can make it using a blender, shaker, or even a glass and spoon (which comes in handy when your shakers are dirty or you need to get out the door quickly). According to the instructions, mix 1 scoop of protein with 6–8 oz of your preferred beverage. For somewhere between 20 and 30 seconds, blend, shake, or mix. You’re left with a lovely, smooth shake after that.

Examining The Big Picture

In terms of macronutrients, each serving of this protein powder provides 23 grams of protein, 2 grams of fat, and 5 grams of carbs. Each scoop or serving has 130 calories. If you want to grow lean muscle and aid in muscle repair, these are good macros to use. You’ll get 46 – 92 grams of protein if you consume the recommended 2-4 servings per day for severe athletes. That would undoubtedly help you increase your protein intake and satisfy your daily protein requirements for muscle growth.

Side Effects

Taking MET-Rx Natural Whey has no negative side effects for me. They keep the recipe basic and eliminate superfluous ingredients such as artificial sweeteners and flavors. I didn’t have any bloating or stomach pain the entire time I was taking it. It does include milk and soy, so if you’re sensitive or allergic, proceed with caution.

The Most Effective Uses

This protein powder is ideal for gaining lean muscle mass and assisting with muscle rehabilitation. It contains 23 grams of protein per serving and BCAAs, which aid in each of these areas. Serious athletes should eat 1-2 servings twice daily for optimum muscular assistance. MET-Rx also recommends taking at least 1-2 scoops right after a workout.


A 2 pound bottle of MET-Rx Natural Whey costs $38.99. The cost of protein per gram is 6.27 cents. For a protein powder, this is about average. I believe it is an excellent value for the money, and because it has 27 servings, it might last you about a month.

MET-Rx guarantees your complete pleasure. They will replace the item or give you a full refund if you are not completely satisfied with it. They don’t give a deadline, simply that the things should be returned as soon as feasible. I appreciate it when a firm gives their consumers a guarantee; it makes all the difference!

What’s The Most Effective Method To Utilize Met-Rx?

Clearly, the most effective approach to use MET-Rx is to make use of all of its features. The combinatorial benefits of beneficial macro and micronutrients and a meal-patterning profile and regular exercise, including progressive resistance training, can have a substantial impact on body composition.

It can also help to increase the body’s lean muscle mass while also enhancing overall vigor and wellness. Meals and snacks (including MET-Rx products) should generally be eaten at regular intervals throughout the day (every three hours or so). This ensures that nutrients are delivered consistently to the bloodstream and that the benefits are maximized.

I’ve heard that eating a well-balanced diet of real foods, without any extra supplements, will help you attain ideal body composition and health. Is this correct?

Yes, it is theoretically feasible to achieve the metabolic benefits of MET-Rx products by eating a well-balanced diet of complete foods, but doing so would be exceedingly difficult. This is why: The unique composition and exact amounts of macro and micronutrients in MET-Rx products result in beneficial metabolic benefits. Metamyosyn, for example, is a mix of multiple distinct proteins with appropriate amino acid compositions and sequences, and is a protein component of MET-Rx. To generate a unique final amino acid array, these proteins are purified, separated, and recombined.

Engineered foods are based on the idea of fortifying natural foods to make them very nutrient rich. Engineered foods give a very high concentration of highly critical nutrients calorie for calorie. Consider a 300-calorie whole-food source that provides:

  • Over 50% of your daily protein need.
  • 100% of your daily calcium requirement.
  • A significant portion of the recommended daily allowance for a variety of vitamins and minerals.

While a few whole foods have high concentrations of a few nutrients, it’s rare to discover any entire foods with a broad spectrum of nutrients at extremely high levels. Furthermore, most people do not have total control over their foods in terms of selection, development, storage, and preparation. Many individuals are becoming increasingly hesitant to cook and consume entire meals at home. Because we consume so much of our daily meals outside of the house, it is nearly hard to be entirely aware of the nutritional qualities of the foods we consume.

With MET-Rx, you can relax knowing that the experts in sports nutrition have already done the legwork for you. It’s never been easier or more convenient to get the advantages of great nutrition.

Benefits Of Met RX Natural Whey

The following are some of the advantages of MET-Rx Natural Whey:

  • Each serving contains 23 grams of protein.
  • Each serving contains 5 grams of BCAAs.
  • Cholesterol, saturated fat, lactose, and carbohydrate levels are all lower.
  • Mixing, dispersion, and solubility are all simple to achieve.

There’s no denying that MET-Rx Natural Whey provides all of these advantages and more.


While we don’t believe this product accomplishes anything particularly well, it will appeal to people who want a little bit of everything. This isn’t a low-carb isolate in the traditional sense, but it’s also free of artificial additives. This product is for people who seek a pleasant protein powder that gives fantastic results and has nothing in it that makes us nervous, all at a reasonable price. As a result, many people find MET-Rx Natural Whey to be an appealing alternative and a perfect beginner’s powder.

Frequently Asked Questions (FAQs)

Who’s Going To Take It?

MET-Rx Natural Whey is designed for athletes and active people over the age of 18 who wish to gain lean muscle growth, improve recovery, and fulfill their daily protein requirements.

How Might Met-Rx Products Help Me Exercise More Effectively?

MET-Rx products have been carefully designed with a detailed nutritional profile to induce particular metabolic benefits and include no fillers. MET-sports Rx’s performance products are designed to deliver excellent nutrition that supports maximum health and fitness and a simple and accessible method for you and your family to get the nutritional advantages of a variety of foods.

What Distinguishes Met-Rx From A Meal-Replacement Product Or Other Nutritional Supplements For General Use?

The phrase “meal replacement” is deceptive. It means your body can tell the difference between the nutrients in a snack and those in a meal, which it can’t. The body simply reacts to the size and nutrient composition of the food it consumes and the pattern of food consumption to metabolize it. MET-Rx products are more than simply a smorgasbord of dietary calories; they are precise nutritional formulas that supply the positive nutrients required for optimal performance.

Several MET-Rx products can be eaten alone or in combination with other foods. They provide a well-balanced nutrient profile and, when eaten as part of a well-balanced, whole-foods diet, can help meet the majority of the body’s nutritional needs.

Is It Okay To Combine Met-Rx With Other Whole Foods? Supplements For Nutrition?

Absolutely. In fact, when combined with other meals, MET-Rx precision nutrition solutions are most effective. With 37-38 grams of protein per serving, MET-Rx original meal replacement powder contains more than 50% protein. Is it possible to eat too much protein in a single sitting?

While any nutrient may be consumed in excess, the quantity of protein in a single meal is very tiny when compared to how much the body can absorb. All nutrients, including protein, are absorbed exceptionally well by the human gut.

What Kind Of Protein Is Most Beneficial To The Human Body, And What Makes Met-Rx Metamyosyn So Unique?

The amino acid makeup of any protein, among other things, influences its physiologic value. Amino acids are the basic building blocks of protein and are required for the majority of metabolic pathways to function properly. They use particular methodologies to quantify and qualitatively assess the impact of consuming certain amino acid arrays on various areas of metabolism.

The amino acid array in the Original Meal Replacement was created to perform well in tests that assess overall protein quality. When used in conjunction with regular exercise and a well-balanced diet, it has been shown to help grow lean muscle mass and improve body composition. In today’s MET-Rx products, there are several modifications of the original Metamyosyn protein combination.

On The Met-Rx Regimen, How Much Total Protein Should You Take Each Day, And What Whole Food Protein Sources Do You


The amount of protein needed per day differs from person to person. In comparison to inactive people, athletes and bodybuilders will require more protein to maintain lean muscle mass. Highly active people should take around 2 grams of high-quality protein per kilogram of body weight per day, or about one gram of high-quality protein per pound of body weight per day. Overweight people should limit their overall protein intake and see their doctor.

When it comes to dietary protein sources, the amino acid content of the whole-food source is the most important factor to consider. The following list includes some whole foods that provide high quality protein sources, based on comprehensive studies on amino acid profiling:

  • Cottage cheese that is low in fat or fat-free.
  • Turkey breast meat that has been deboned and skinned.
  • Whites of eggs
  • Tuna, salmon, and halibut are among the many seafood available.
  • Skinless chicken breasts that have been broiled.
  • Red beef slices that are lean.

Is Met-Rx Appropriate For Those Who Do Not Live Active, Athletic Lives?

Without a doubt. Even inactive individuals on a regular basis can benefit from MET-Rx nutrition supplements combined with a balanced diet. The optimal nutrient composition of MET-Rx products, the meal patterns suggested in the guide, and the whole foods recommended all contribute to improved metabolic function and overall health. They recommend that everyone engage in some form of daily activity for optimal health and body composition.

Can Women Benefit From Using Met-Rx Medications And Following The Meal Plans That Are Recommended?

Women who wish to enhance their looks and general health might benefit from the MET-Rx program, which offers numerous distinct benefits. Women may achieve their ideal physique by using MET-Rx sports nutrition products and following the recommended meal programs. The MET-Rx food plan is designed to assist your metabolism when paired with a regular exercise routine. You may enjoy eating balanced meals and snacks throughout the day with MET-Rx.

Seniors will benefit from the substantial nourishment provided by MET-Rx products. As we grow older, we lose more nitrogen and body protein, making it more difficult to obtain the nutrients we require. Maintaining muscular mass and strength is essential for a healthy lifestyle. Optimal diet is essential for good health at any age. MET-Rx is beneficial to almost everyone.
