Whey Protein Side Effects:
Maladies and Ailments

Whey protein side effects can be very harmful to your health. The human body needs sources of protein that have minimal or no adverse impact on bodily systems. And only plant-based whole foods can offer you that.

Here are some possible side effects.

Whey Protein Side Effects - LACTOSE INTOLERANCE

Lactose is milk sugar and many people find it difficult to digest it. Some unrefined forms of whey protein contain higher levels of lactose. The standard whey protein powder will have about 5-6 % lactose.

Whey Protein Side Effects - ALLERGIC REACTIONS

Lactose intolerant people usually have allergic reactions to dairy products. Whey protein is a highly refined form of dairy. Some allergic symptoms from ingesting whey are:

  1. Rash
  2. Hives
  3. Itching
  4. Vomiting
  5. Coughing
  6. Wheezing
  7. Breathing difficulties
  8. Swellings: lips, mouth, or throat
  9. Diarrhea or blood in the stool (especially in infants)

Whey Protein Side Effects - OVERLY ACIDIC BLOOD PH

Milk is easily the most acid-forming food material, with lots of proteins and calcium. And therefore so is whey. A range of 7.0 to 7.4 is a suitable alkaline pH value for blood. Whey is a low fat animal food very high in proteins. Excessive protein intake causes higher acid levels in the body and thus in the blood. Then the body has to self-regulate to restore blood alkalinity by releasing minerals from the bone including calcium.


The body uses calcium from the bones to reverse the effects of blood acidity. High blood calcium levels increase the presence of calcium in the urine. Excess calcium creates stone formation and possible kidney disorders.

Ammonia is a byproduct of protein digestion and it’s the liver’s responsibility to detoxify ammonia as a waste material. Heavy consumption of whey protein can stress the liver and damage this organ.


Calcium is an alkaline mineral stored mostly in the bones of the body. Whenever the blood becomes acidic, the body releases bone calcium into the blood stream to restore and maintain alkalinity. Long term use of whey and other dairy foods can cause a depletion of calcium deposits in the bones. The outcome of this is a mineral imbalance in the bones, with ensuing joint problems and osteoporosis.

These are some other side effects you can experience from excessive consumption of whey protein:

  1. Increased frequency of bowel evacuations
  2. Loss of appetite
  3. Headaches
  4. Bloating
  5. Fatigue
  6. Cramps
  7. Thirst

To conclude…

The most acidic food substances available to you are milk and dairy products. These foods are also very high in animal proteins and calcium. Excessive consumption of milk and dairy foods can be quietly lethal. Whey protein is a processed expression of cow's milk.

Phytonutrients from plants are best for the human body. It is a basic design by nature through the vehicle of plants to efficiently nourish the body with all required nutrients inclusive of amino acids. A whole foods plant-based diet is best for maintaining the alkaline levels of blood.

Bones need exercise just as muscles. And lack of exercise will cause bone density issues and osteoporosis. Lack of exercise will thus further exacerbate skeletal problems from using animal protein such as whey.
