Dog Cancer 4X more likely if low Vitamin D – Nov 2015

New Study Shows Dogs with Low Vitamin D Are At Risk For Cancer DogsNaturally

Some other factors that are known to decrease the ability to convert dietary vitamin D to 25-VitD:

• Polyunsaturated fats can decrease the bioavailability of vitamin D
• Fluoride (which is present in many pet foods and water supplies)
  decreases magnesium, which is an essential cofactor for vitamin D
• Strong magnetic fields can reduce vitamin D levels
• PCBs increase the risk of deficiency by 3%
• Roundup (glyphosate, which is present in foods and the environment) decreases vitamin D
• Flame retardants (which are 10 times higher in dogs than humans) inactivate vitamin D
• Low magnesium in foods
• Spay/Neuter (spayed females have 10% less 25VitD than intact females and neutered males have 30% less than intact males)
• Kidney disease (prevents the conversion of 25VitD to the usable form of vitamin D)
• Exposure to DDT and other pesticides
• Certain drugs (as well as St Johns wort and mineral oil) can consume or block vitamin D
