Dogs and Cats still need vitamin D – July 2021

Vitamin D metabolism and disorders in dogs and cats

Vitamin D plays an important role in regulating calcium metabolism and in the development and maintenance of skeletal health of companion animals. There is also a growing interest in understanding the role vitamin D plays in non-skeletal health in both human and veterinary patients. This review provides an update of our current understanding of vitamin D biology in dogs and cats and gives an overview of how vitamin D metabolism can be assessed in companion animals. Congenital and acquired vitamin D disorders are then summarised before the review concludes with a summary of recent studies which have explored the role of vitamin D in the development and outcomes of non-skeletal diseases of dogs and cats.

Overview Veterinary and vitamin D has the following

Veterinary category has 147 items

Animals need Vitamin D too

Pets as well

Farm Vets are paid when their "patients" are healthy,
   vs doctors who are paid only when "patients" become sick

_Cows are routinely given 30 IU per kilogram (which would be 10,000 IU for a 150 lb person)
Same information is available on Cattle need 66 IU of vitamin D per pound
The US RDA of vitamin D for cows is 13 IU per kilogram (which would be 4,300 IU for a 150 lb 'cow')
Virtually all US farmers who raise livestock use feed which is supplemented with vitamin D
Merick Vet Manual supplement if not have UV or sunlight
