Whole Food Sources of Manganese For Dogs

Dogs need to be fed manganese through the diet in the amount of  1.25 mg/1000kcal daily for adult dogs.

Think of manganese as the vitamin “uber” transporting the rest of the vitamins from the gut to the body.

The Small Animal Clinical Nutrition states that manganese is a component and activator of enzymes (glycosyl transferases), lipid and carbohydrate metabolism, bone development (organic matrix), reproduction, cell membrane integrity (mitochondria).


Impaired reproduction, fatty liver, crooked legs, decreased growth.

Deficiencies have also been linked to CCL injuries.


Relatively non-toxic.

Why Is Manganese Lacking In Diets

Poor quality kibble and unbalanced cooked and raw diets do not contain enough manganese.

Whole Food Soures of Manganese

Manganese (Mn) [mg/100g]

Cinnamon: 17.46

Mussel, blue, cooked, moist heat: 6.8

Sesame seeds, dried: 2.46

Brown rice 1.03

Clam 1

Oyster, cooked, moist heat: 0.59

Oats: 0.56

Green Tripe – raw: 0.44

Kale, cooked: 0.42

Apples, raw, with skin: 0.03

Squash, acorn, cooked: 0.24

Blueberries: 0.2

Asparagus: 0.15

Interestingly enough, the highest level of manganese can be found in cinnamon and it actually came up during a call when I was receiving training from Animal Diet Formulator on how to use their software. The question of palatability came up – because not all dogs will eat food that has cinnamon.

Manganese Supplements

Kibble, cooked and raw meals that are formulated to AAFCO’s standards technically do not need additional manganese supplemented.   You might see it as an ingredient as manganese oxide, manganese sulfate, manganous chloride, and manganese carbonate.

Food that is labeled “for supplemental feeding” may or may not have sufficient levels of manganese. Look at the label to verify levels or contact the manufacturer for the information.  

If you are feeding DIY cooked, raw, or using unbalanced commercial grinds or mixes you will want to supplement or feed food sources that contain manganese. Ionic drops work well because you can tailor the dosage to the size of your dog.

      Hello Lynn. You’re absolutely correct. I just updated the list. I pulled it up and you can find it right under oats. 0.44 mg/100g of green tripe. Also more about Green Tripe here: https://dailydogfoodrecipes.com/green-tripe-has-no-probiotics-or-enzymes/
