Does Protein Powder Give You Gas

The Benefits and Side Effects of Protein Shakes Explained for Beginners

There isn’t any scientific evidence that proves that a high protein diet can cause an increase in flatulence. While there is some evidence showing that protein powders can increase flatulence, this is mainly because of undigested lactose components paired with the users inability to break it down.

In general gas is a systemic issue and requires a systemic solution. Even if you don’t have a lactose sensitivity, a high lactose diet can increase flatulence. Some protein powders contain additives that can also contribute to flatulence, such as sorbitol, gums, thickening agents, “natural flavors” and other types of both natural and artificial sweeteners.

Certain types of protein powders can increase flatulence, but they can also make the gas your passing smell terrible. The main culprit behind protein powder giving you gas is the quality of the whey protein itself.

Not all whey protein is created equally, as some cheaply made whey protein concentrates can have additives that make you bloat like crazy.

You should also make sure that you’re reading through the ingredient list of the whey protein powders that you are purchasing.

Make sure that the whey protein powders you are purchasing contain limited filler ingredients, flavors, and sweeteners.

How Much Should You Take

You can take whey protein powder simply by mixing it with water or a liquid of your choice.

Its important to follow the serving instructions on the package. Taking more than the listed amount is not recommended. Also, be sure to follow any additional directions that may be provided by your doctor or dietitian.

In general, its a good idea to talk with your doctor before adding supplements to your diet.

If you have lactose intolerance, you may find whey protein isolate or non-dairy protein powders easier to tolerate. Non-dairy protein powders may come from sources such as pea, egg, rice or hemp.

People with cows milk allergy should not take whey protein, because it is a milk product.


When taking a whey protein supplement, be sure to follow the serving instructions on the package. Do not take more than the recommended amount.

You Don’t Need The Extra Protein Or The Heavy Metals Our Tests Found

The promises are enticing. Whether you’re looking to shed unwanted pounds, get a quick energy jolt, build muscles, or fight the aging process, protein drinks are being boosted by some supplement makers as a scientifically proven way to quickly achieve your goals.

The products, sold as ready-to-drink liquids or powders that you mix with milk, juice, or water to make shakes, attract not just athletes and body-builders but also baby boomers, pregnant women, and teenagers looking for a shortcut to a buff body.

Some ads say that protein supplements, in flavors such as strawberry and vanilla cream, can be a nutritious and time-saving snack or meal replacement.

In a testimonial for BSN Lean Dessert Protein Shake, “fitness celebrity” Jennifer Nicole Lee says, “Being a busy mom with 12-hour workdays, I rely upon my Lean Dessert Protein to get adequate amounts of protein without wasting time on creating complex meals ….”

Another product, Muscle Milk, boasts on its website: “Designed after one of nature’s most balanced foods: human mother’s milk ….”

Uses Of Casein Protein Powder

Side effects of whey protein

Casein is one of the most nutritious milk proteins and accounts for about 80% of the proteins in milk, cheese, and yogurt. All mammals produce the casein component in their milk for their offspring. This type of protein can be found in protein powder, dietary supplements, and dairy-based baby formula. Whether it’s for muscle recovery, muscle growth, weight management, or reaching your daily nutrient goals, protein powder is a useful supplement that can be added to your daily routine. Keep reading to learn more about the uses of casein protein powder, the potential side effects, and what to look for when purchasing a casein protein powder.

Protein in the form of a dietary supplement is often not as necessary as people might think, especially when it comes to reaching your daily nutrient intake. Protein deficiency in the United States is quite rare, and daily protein supplements should be taken at the recommendation of your physician or nutritionist. Casein protein powder can be used to achieve goals when it comes to:

Muscle building and recovery

Bone health

Weight management

Medical conditions

Casein protein powder has been used in the treatment or management of certain medical conditions. However, there is insufficient evidence that shows how casein protein directly affects these conditions. Some of the medical conditions that have shown some evidence of being positively affected by casein protein include:

Protein Powders May Be Doing More Harm Than Good

Jared Hirschfield, National Center for Health Research

Protein powders have become increasingly popular in recent years among a wide range of people from professional athletes to those too busy to grab a full meal. They assume that supplementing their diet with sports nutrition powders is a safe and easy way to add muscle faster and recover more quickly. Many of these products are advertised as natural or organic and promise immediate and dramatic results.

But are these supplements actually safe? In addition to protein, these powders often contain potentially harmful chemicals, and some are even contaminated with toxins and metals. How could that be? Under the Dietary Supplement Health and Education Act, no dietary supplements, including protein powders, are regulated by the FDA to make sure they are safe or effective. There is also no requirement that supplements be tested to make sure they contain what the labels say they contain. Research has shown that many dietary supplements sold in major drug store chains, natural food stores, and respected online outlets do not contain what they are supposed to or contain ingredients not listed on the label.

Are Protein Drinks Safe For Kids

For children with protein deficiency or another medical condition that keeps them from getting enough protein, protein drinks can be used to supplement their diet.

However, there is a lack of evidence supporting the benefits of protein powder for children with these illnesses. In a 2015 review, researchers studied the evidence surrounding the effects of protein supplementation in children with chronic illnesses like cystic fibrosis and pediatric cancer. These illnesses often keep children from getting adequate nutrition. This study found no significant improvements in weight, height, or nutritional status.

For most healthy children, protein supplements are unnecessary. Protein deficiency is uncommon in the United States, and most children with a well-balanced diet get the recommended amount of daily protein.

For most self-identifiers of lactose intolerance, dairy products are off the menu as a dietary source for their protein macros. Lactose intolerance is a type of digestive disorder. The lactose-intolerant population struggles to efficiently breakdown lactose, the main carbohydrate found in dairy products and dairy by-products.

Despite their potential health benefits, high-protein diets may cause adverse effects, reports a November 2014 review published in âNutrition & Metabolismâ. When consumed in excess, protein may affect your kidneys. The risks may be even greater for people with kidney disease.

Beware that high protein intakes may contribute to weight gain when energy expenditure is low. This nutrient supplies 4 calories per gram. If you don’t burn the extra calories, they’ll add up and can cause you to gain fat.

Additionally, your body has the ability to convert excess protein to glucose, which may further increase the risk of gaining weight. If you’re physically active, a high-protein diet will work in your favor. Unfortunately, it’s not the best choice for those with a sedentary lifestyle.

Other Potential Negative Side Effects

In addition to weight gain, consuming too many protein shakes could cause other negative side effects.

  • Nutrient deficiency. If you use protein powder shakes as replacements for several meals a day, “there could a risk of not getting enough of other important nutrients,” says registered dietitian nutritionist Trista Best, RD at Balance One Supplements.
  • Constipation. Many protein powders lack fiber, which can cause constipation, Best says. And long-term use of protein supplements may cause a gut microbiota imbalance, according to a 2018 study in Nutrients.
  • Impaired kidney function. Before drinking high-protein shakes, “check with your doctor if you have kidney disease to ensure added protein is safe for your kidneys and what your limits should be,” Poston says. Protein metabolism can be taxing on the kidneys, according to a 2020 study.

Whey Protein Side Effects

Whey protein shakes are an excellent pre- or post-workout snack. Whey protein can be helpful in building muscle mass or replenishing your body after rigorous exercise.

You May Drop A Few Pounds Quickly

High fat and protein diet is what a lot of people on the keto diet experience. A high protein diet may cut carbs significantly and you’ll lose some water weight right away. This is because carbohydrates store water in the muscle for energy as glycogen, so when carbs are cut out, the stored glycogen and water is released.

“This can be encouraging for people who are trying to lose weight and need a jumpstart,” say the Nutrition Twins. “Just keep in mind that if you don’t cut calories, the weight isn’t body fat weight, and will come back as soon as you start adding carbs back in.”

How Much Protein Do You Actually Need

Does Too Much Whey Protein Cause Side Effects?

The European Food Safety Authority developed the dietary reference values for protein. An average adult is expected to consume at least 0.83g and maximum of 1.2 of proteins per kg of body weight per day.

In other words, an average 70kg person should take at least 58 g of protein and maximum of 84g of protein every day.

Surprisingly, this much amount of protein is easily fulfilled by consuming 3-4 servings per day of diverse beans, lentils and grains.

You May Get Sick More Often

If you’re getting too much protein, you’re likely not eating other foods such as fruits, vegetables and whole grains, which contain powerful antioxidants and anti-inflammatory compounds that help to protect your immune system and fight disease.

In a review done by Critical Care Medicine Journal, protein calorie malnutrition could lead to an impaired host immunity with particularly harmful effects on the T-cell system, which is part of the immune system and develops from stem cells in the bone marrow, resulting in an increased chance of infection and increased morbidity and mortality in hospitalized patients.

Increased Heart Attack Risk

A recent animal study published in the journal Nature Metabolism showed that high protein diets may directly affect cardiovascular health, potentially increasing the risk of a heart attack.

Researchers evaluated two groups of miceâone fed a high fat, high protein diet , and the other a high fat, low protein diet. It turned out that the mice on the high fat, high protein diet developed significantly worse arterial plaque than the mice on the high fat, low protein diet.

What’s more, the plaque in the rodents’ arteries was of the unstable variety that tends to break apart and increase heart attack risk.

“Our study shows how and why dietary protein leads to the development of unstable plaques,” says Dr. Babak Razani, an associate professor of medicine from Washington University School of Medicine in St. Louis, MO told Medical News Today. “A couple of scoops of protein powder in a milkshake or a smoothie adds something like 40 grams of proteinâalmost equivalent to the daily recommended intake.”
