Does Too Much Whey Protein Cause Side Effects?
Whey protein is one of the most popular supplements on the planet.
But despite its many health benefits, there’s some controversy surrounding its safety.
Some claim that too much whey protein can damage the kidneys and liver.
The key difference between the three main types of whey protein is how they are processed.
Whey protein concentrate: Contains 70–80% protein.
It’s the most common type of whey protein and has more lactose, fat and minerals from milk.
Whey protein isolate: Contains 90% protein or more.
It’s more refined and has less lactose and fat, but it also contains fewer beneficial minerals.
Whey protein hydrolysate: This form is predigested, allowing your body to absorb it faster.
Whey protein is the most popular choice among athletes, fitness enthusiasts and people wanting to build muscle or lose weight.
Does It Cause Digestive Issues?
Some people have problems digesting whey protein and experience symptoms such as bloating, gas, stomach cramps and diarrhea.
Most of these side effects are related to lactose intolerance.
Lactose is the main carbohydrate in whey protein.
People who are lactose intolerant don’t produce enough of the enzyme lactase, which your body needs to digest lactose.
If you are lactose intolerant, try switching to a whey protein isolate powder.
Whey protein isolate is more refined, with a much smaller amount of fat and lactose than whey protein concentrate. People with lactose intolerance can usually safely take whey protein isolate.
Other options would be a non-dairy protein powder, such as egg, soy, pea, rice or hemp protein.
Could You Be Allergic To Whey Protein?
People with a cow’s milk allergy may be allergic to whey protein.
However, it is very rare for adults to have cow’s milk allergies, since up to 90% of people with cow’s milk allergies outgrow them by the age of three.
Symptoms of a cow’s milk allergy may include hives, rashes, facial swelling, throat and tongue swelling and a runny or stuffy nose.
In some cases, a cow’s milk allergy may trigger anaphylaxis, a severe, life-threatening allergic reaction.
A lactose intolerance could very easily be confused for an allergic reaction.
Constipation and Nutritional Deficiencies Caused By Whey Protein…?
Whey protein cannot be blamed for any constipation that may result when someone has removed fruit and vegetables from their diet in favor of whey protein when they are on a low-carb diet.
Fruits and vegetables are a great source of fiber, which helps form stool and promotes regular bowel movements.
Whole foods, especially fruits and vegetables, are nutrient-rich and contain a variety of minerals necessary for optimal health.
It’s important to keep eating a balanced diet while you’re taking whey protein.
Kidney or Liver Damage…??
Eating a high-protein meal can raise the pressure inside the kidneys and cause them to filter more blood than usual.
But, this does not mean that a high-protein meal harms the kidneys of healthy people.
That said, there is evidence that a high-protein diet can be harmful for people with kidney disease.
A high-protein diet in those with kidney disease may further damage the kidneys.
It is always advised to check with your doctor before beginning a supplement to make sure it is safe for them…that goes for everyone!
The liver needs protein to repair itself and convert fats to lipoproteins, which are molecules that help remove fats from the liver.
There is no evidence that too much protein can damage the liver in healthy people. However, people with liver disease should check with their doctor about whether whey protein is safe for them.
Whey protein is safe and many people can take it without any problem.
It may cause digestive symptoms in those with lactose intolerance, and those allergic to cow’s milk may be allergic to it.
If you experience side effects, try a whey protein isolate or non-dairy protein alternative.
Whey protein is one of the best supplements on the market. It has a wide range of benefits in strength and muscle building, recovery and weight loss.
