- Vitamin D in eggs increased 4X after UV lighting near legs was added – April 2019
- Hens with Vitamin D were better in at least 5 ways – RCT Aug 2018
Pets as well
- Critically ill dogs with good levels of vitamin D have much better outcomes (humans too) – March 2018
- Half of dogs now get cancer, it used to be just 1 percent (probably low Vitamin D)
- Dogs, cats, rabbits, guinea pigs, pet birds, etc need Vitamin D
- Dogs with Cancer have low vitamin D, same as humans – Sept 2017
- Companion animals (dog, cats) need vitamin D too – March 2016
- Hospitalized cats 8X more likely to die if low vitamin D (Vit. D helps humans too) – May 2015
- Rickets increasing in dogs
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 that is supplemented with vitamin D
Merick Vet Manual supplement if not have UV or sunlight

Low blood 25-hydroxyvitamin D (25(OH)D) concentrations have been associated with cancer in dogs. Little research has examined what other factors may affect 25(OH)D concentrations.OBJECTIVES:
(1) To determine whether the presence of cancer (lymphoma, osteosarcoma, or mast cell tumor [MCT]) in dogs is associated with plasma 25(OH)D concentrations and (2) identify other factors related to plasma 25(OH)D concentrations in dogs.ANIMALS:
Dogs newly diagnosed with osteosarcoma (n = 21), lymphoma (n = 27), and MCT (n = 21) presented to a tertiary referral oncology center, and healthy, client-owned dogs (n = 23).METHODS:
An observational study design was used. Dietary vitamin D intake, sex, age, body condition score (BCS), muscle condition score (MCS), and plasma concentrations of 25(OH)D, 24,25-dihydroxyvitamin D (24,25(OH)2 D) (a marker of CYP24A1 activity), as well as ionized calcium (ICa), parathyroid hormone, and parathyroid hormone-related protein concentrations were measured. An analysis of covariance was used to model plasma 25(OH)D concentrations.RESULTS:
Cancer type (P = 0.004), plasma 24,25(OH)2 D concentrations (P < 0.001), and plasma ICa concentrations (P = 0.047) had significant effects on plasma 25(OH)D concentrations. Effects of age, sex, body weight, BCS, MCS, and plasma PTH concentrations were not identified. A significant interaction between ICa and cancer was found (P = 0.005). Plasma 25(OH)D concentrations increased as ICa concentrations increased in dogs with cancer, whereas plasma 25(OH)D concentrations decreased as ICa concentrations increased in healthy dogs.CONCLUSIONS AND CLINICAL IMPORTANCE:
Results support a relationship between cancer and altered vitamin D metabolism in dogs, mediated by plasma ICa concentrations. The CYP24A1 activity and plasma ICa should be measured in studies examining plasma 25(OH)D concentrations in dogs.Dogs with Cancer have low vitamin D, same as humans – Sept 2017Printer Friendly Follow this page for updates5798 visitors, last modified 20 Sep, 2022, This page is in the following categories (# of items in each category)Attached files
