Does Muscle Milk Stunt Growth

In this brief article, we will answer the question, “does Muscle Milk stunt growth?”, and will also address the functionality, benefits, safety, and possible side effects of the product. 

Does Muscle Milk Stunt Growth?

No, Muscle Milk does not stunt growth.

In fact, it is almost impossible for any supplement to stunt growth since the latter is caused by an inadequate supply of nutrition, an illness, or some genetic condition. Differences between human groups in the average values for size, body proportions and body composition are due to an interplay between genetic and environmental determinants of growth and development (1).. 

Muscle Milk, on the other hand, is a great source of overall nutrition that can help overcome illnesses related to malnutrition.

Can Muscle Milk Help You Grow Taller?

No, Muscle Milk cannot make you grow taller. Muscle Milk does provide the nutrients that can help your muscles and bones grow strong, and can help you achieve your body’s full potential.

Nothing can make you grow taller than your genetic predisposition. Growth and nutrition are closely related and the lack of nutrients may delay growth. However, many studies have shown that height, weight, body composition and skeletal development are related to both hereditary and environmental aspects of human beings (1).

What is Muscle Milk?

Muscle Milk is a globally recognized nutritional supplement drink developed by CytoSport which is easily available at supplement stores and most corner markets. 

It is mainly used by athletes and fitness trainers because the combination of high-protein and low-carbohydrates helps provide extra protein for pre and post-workout recovery.

Its ingredients include sodium caseinate, calcium, milk protein isolate, functional fats, fructose, maltodextrin, potassium citrate, a vitamin-mineral blend, and others. Among milk proteins, it contains whey milk proteins. 

Protein quality is a function of protein digestibility, amino acid content, and the resulting amino acid availability to support metabolic function. Whey protein is one of the highest-quality proteins given its amino acid content (high essential, branched-chain, and leucine amino acid content) and rapid digestibility. Consumption of whey protein has a robust ability to stimulate muscle protein synthesis. In fact, whey protein has been found to stimulate muscle protein synthesis to a greater degree than other proteins such as casein and soy (2).

How Does Muscle Milk Work?

Muscle Milk provides athletes with medium-chain triglycerides, which are readily broken down and utilized by the body to produce heat and energy for a better and more energetic workout. Resistance exercise alone stimulates muscle protein synthesis, but it also increases muscle protein breakdown, resulting in a net loss of muscle protein in the absence of an increase in amino acid availability. With the provision of protein following a bout of resistance exercise there is a synergistic effect of resistance exercise and protein, resulting in a greater increase in muscle protein synthesis than either stimulus would induce (2).

Moreover, the complex amino acids and proteins present in Muscle Milk help repair tissue damage experienced during intense workouts. Higher Protein diets have been shown to: (1) promote gains in muscle mass, especially when paired with resistance training; (2) spare muscle mass loss during caloric restriction; and (3) attenuate the natural loss of muscle mass that accompanies aging (2).

Is Muscle Milk Safe?

Yes, but there’s a catch. Even though its ingredients are not outright harmful, the answer to this question depends mainly on the individual taking it. 

For instance, people suffering from chronic diseases such as high blood pressure, kidney problems, or sensitivities to artificial sugars and food dyes must carefully read the product’s label before consuming the product.

If you’re unsure about whether you should try Muscle Milk, consult a qualified health professional.

Overall, Muscle Milk is preferred over other commercial whey or creatine supplements since it provides more energy during workouts. This is probably because the product is made to somewhat mirror the composition of mother’s milk, while also containing additional supplements that make it more useful for individuals wanting to build muscle.

Side effects related to whey supplementation are due to excessive use. Among the adverse effects are the increase in the presence of acne, dysfunction of the microbiota, and modifications in the regular metabolism of the kidneys and liver. The main concern is a possible overload of the kidneys due to an increase in the pressure and rate of glomerular filtration from a hyperproteic diet, since urea, the main product of protein metabolism, is excreted by this organ (3). 

Why Is Muscle Milk Not Considered ‘Healthy’?

Nutrient supplementation can help avoid diseases and mass loss after physical effort and training. In addition, whey-derived bioactive components have antimicrobial and antiviral properties, and enhance immune defense and bone health, and improve  antioxidative activity, and help protect against cancer and cardiovascular disease, and enhance the performance of physically active individuals, among other benefits (4). However, when taken in excess or by individuals with kidney and liver malfunctions, it can lead to harm. It is not recommended for those who are allergic to milk protein or lactose intolerant people (3).  

 There have been certain controversies concerning Muscle Milk that have raised significant concerns about its safety. We’ll address some of these now.

  • Muscle Milk also contains artificial sweeteners. According to the Center for Science in the Public Interest, consumers must avoid these types of sweeteners, since they alter the population of healthy gut bacteria, can be found in breastmilk, and increase the risks of certain diseases.
  • Even though Muscle Milk isn’t actually ‘milk’, it does contain the two major proteins found in milk – whey and casein proteins. These derivative proteins can cause allergic reactions in sensitive people.
  • A 10-ounce bottle of Muscle Milk contains 18 grams of protein. This puts people with kidney disease at significant risk, since some require a high-protein diet while others require a low-protein.
  • Since excess protein is metabolized by the kidneys, Muscle Milk can cause them to overwork which can be a potential problem for those suffering from kidney insufficiency. Hence, it is advised that you drink adequate amounts of water to help the kidneys flush additional protein.

Is Muscle Milk Safe For Kids And Young Athletes?

Yes, but parents must carefully consider all the factors involved in maintaining their child’s nutritional and workout needs, such as the need for any additional vitamins or nutritional adjuncts. Recent studies have shown that whey protein fed children had no diarrhea (4). 

Before relying on nutritional supplements, the goal must be to attain a balanced, healthy diet. A health professional is to be consulted if the child does not meet growth and body development expectations (1).
