Title: Vitamins


1
Vitamins
  • Organic compounds necessary for normal
    physiologic function. Most cannot be synthesized
    in the body and must be present in the diet.

2
There are two categories of Vitamins
  1. Fat soluble (A, D, E, and K)
  2. Water soluble (B complex vitamins and vitamin C)

3
1. Fat Soluble Vitamins (A, D, E, K)
  • Require bile salts and fat clusters for
    absorption through the wall of the duodenum and
    ileum.
  • Are stored in lipid deposits in all tissues and
    are therefore required in smaller daily doses.
  • Over supplementation may lead to toxic
    syndromes. More is not better and will not
    improve performance.

4
Vitamin A, D, E K Sources
  • A Cod liver oil, milk, liver, egg yolk
  • D Liver, some fish, egg yolk, sunlight
  • E Wheat germ, corn and soybean oils
  • K Green leafy plants, liver, some fish meals

This information is not in your book.
5
Vitamin A
  • Plant sources have carotenoids (provitamin A)
  • Dogs can convert this to the active form needed.
  • Cats do not have the enzymes necessary to convert
    this to the active form. (another reason cats
    should not be fed vegetarian diets)

6
Vitamin D
  • Dogs and cats cannot use sunlight to convert
    provitamin D to the active form.
  • The active form of vitamin D is a hormone that
    works with calcitonin (parathyroid hormone),
    calcium, and phosphorus.

7
Vitamin E
  • Main function is an antioxidant.
  • This makes it useful as a preservative in pet
    food.
  • Pansteatitis

8
Antioxidants
  • Antioxidants function by stabilizing free radical
    molecules, which otherwise would have destructive
    interactions with surrounding tissues. They help
    to restore damaged tissues.

9
Vitamins C and E are Antioxidants
  • These vitamins help free the body of the damaging
    effects of free radicals.
  • Supplementation of these vitamins above the
    normal daily requirements can therefore be
    beneficial to the animal. In this case more means
    better. But dont go vitamin crazy.

10
Vitamin K
  • Can be absorbed from dietary sources or
    synthesized by microbes in the large intestines
    of dogs and cats

11
Vitamin K Deficiency
  • Vitamin K plays a critical role in blood clotting
    formation!
  • This means that deficiencies hemorrhage
    (bleeding to death)
  • Warfarin is a rodent poison that when ingested by
    cats from eating a rat or mouse, causes fatal
    hemorrhage if emergency supplementation of
    vitamin K is not administered.

12
2. Water Soluble Vitamins (B complex vitamins and
vitamin C)
  • Are poorly stored in the body
  • Excesses are lost via the urinary tract
  • Frequent intake is critical
  • Depleted faster, so that toxic effects are less
    likely to occur than deficiencies

13
Vitamin C Ascorbic Acid
  • An important water soluble vitamin, but is not
    necessary in the diet of dogs and cats as
    metabolism of glucose produces adequate amounts
  • Serves as an antioxidant
