Dog Food Ingredients 101: Manganese Sulfate

April 15, 2023

#AtoZChallenge 2023 letter M If you feed your dog commercial dog food, have you ever taken the time to go down the list of ingredients to learn what each one is?  It’s a daunting task!  As of today, I’m two weeks into my April blogging from A to Z Challenge, which has been focused on taking a deep dive into learning more about some of the ingredients found in commercial dog foods.  I hope you’ve learned something useful so far, and continue to stop by as we learn about a new dog food ingredient (almost) everyday this April!

This post is part of our 2023 April blogging from A to Z Challenge!  Join us this month as we go through the alphabet, A to Z, learning more about some of the ingredients that are commonly (or not so commonly, in some cases) found in our dog’s food!

What is Manganese Sulfate?

Manganese sulfate, formula MnSO4·H2O, is an inorganic compound that is pale pink in color.  Manganese is found naturally in seeds, nuts, whole grains, eggs, and green vegetables.

Why is Manganese Sulfate Added to Dog Food?

Although manganese is naturally present in some foods, many dog food companies also add supplemental manganese into their dog foods.  Manganese helps the body process protein, carbohydrates, and is important for proper enzyme function.  Some of these enzymes are involved in energy production and the creation of fatty acids.  Manganese helps keep the skeletal system, ligaments, cartilage, and organs, especially the liver and kidneys, healthy

Dogs require 2.3 mg of manganese per pound of dry food daily.

Cons of Feeding Manganese Sulfate to Dogs:

The effects of manganese toxicity are unknown.  It would be very difficult, if not impossible, for a dog to be exposed to enough manganese that it would result in toxicity.  The amounts of manganese found in dog foods are safe for dogs.

Benefits of Manganese Sulfate to Dogs:

Dogs require small amounts of manganese to keep their bodies functioning normally.  Symptoms of manganese deficiency include poor growth, reproductive issues, ataxia (wobbly movements, tremors, eye flickering), skin and coat abnormalities, and issues with the skeletal structure and joints.

Manganese is required for enzymes in dog’s bodies to function properly.  These enzymes, in turn, are important for many functions including energy production, fat metabolism, protein metabolism, carbohydrate metabolism, bone, cartilage, and collagen formation, brain function, and immune system function.

So What’s the Verdict on Manganese Sulfate?  Is it Safe as a Dog Food Ingredient?

Manganese is not only safe (it’s considered to be one of the lest toxic trace elements), it is required by dogs for proper body function.  Manganese is not commonly found in meat.  If your dog eats a diet especially high in meat protein, it’s common for dog foods to add supplemental manganese.
