Magnesium Stearate can be found in about 95% of supplements sold in pharmacies, stores and/or supplied by doctors and veterinarians to their patients.

Magnesium Stearate is a lubricant that acts as a slipping agent. 

It is created by adding a magnesium ion to stearic acid. 

Magnesium Stearate is added to pills and capsules to:
  • Keep the pills/capsules from sticking to each other;
  • From sticking to the machinery, which in turn...
  • Means that they processing plant can run the processing/production machinery at a higher speed...
  • Which means that they can increase production while requiring less inspection on the production line to ensure uninterrupted processing.
  • Culminating in better profit margins. 
Magnesium Stearate may be good for company profit but it is seriously bad for yours and your dogs health and here is why...

The Problem Is...


1.0 Stearic Acid is Typically Made Using Hydrogentated Cottonseed or Palm Oil.

These oils pose a real health risk:
  • Of all commercial oils, cotton seed has the highest content of pesticide residue.  
  • Cottonseed oil is used to coat the supplement – which means it is coating the nutrients in the supplement.
  • As a coating agent the cottonseed oil slows down/delays the absorption of the nutrients in the intestines.
  • The other problem with cottonseed oil is that it often comes from Genetically Engineered seed crops – long-term studies on the health effects of ingesting GE is not known.
  • In large amounts magnesium stearte damages the skin and liver…remember that most dogs are smaller than adult humans it would take less magnesium stearate to damage a dog.
2.0 Why is the Delay in the Absorption of Nutrients Bad?

Depending on what your dog is eating with the supplement the food may be pushed through the GI tract at a faster pass than the nutrients in the supplement can be absorbed. Your dog may not get to benefit from some or all of the nutrients meant to be delivered by the supplement. At best your money is thrown away, at worst your dog may be in serious trouble from lack of the required nutrient.


3.0 Magnesium Stearate - as Noted Above Contains Stearic Acid. 
  • Stearic acid suppresses T cells. 
  • Why does that matter? 
  • T-cells (T lymphocytes) are part of the lymphocytes group of white blood cells.
    Lymphocytes play a key function in cell-mediated immunity. 
  •  T Cells are killer cells, and are very important to good immune system function. 
  • Stearic acid causes the collapse of the cell membrane in these very important T cells. 
  • Collapse occurs when the T-cells are exposed over time to damaging doses of the acid. Collapse of the cell membrane leads to the destruction of cell function.

In my opinion the above provides sufficient reason to steer clear of magnesium stearate. 



It seems to me that the pharmaceutical companies are incredibly unethical as is the pet industry…here are a few more examples...
