Q

what is the difference between a drug and a supplement?

A

a drug is used to diagnose or treat a disease but a supplement is used to provide a nutrient that isn’t included in the pet’s current diet

Q

calcium functions

A

provides structural integrity to skeleton and contributes to maintenance of blood calcium levels through ongoing resorption and deposition
circulating calcium has roles in nerve impulse transmission, muscle contraction, blood coagulation, activation of enzymes, maintenance of cell membrane permeability and transport, and cardiac function

17
Q

phosphorus functions

A

in bone: lends structural support, released into bloodstream in response to homeostatic mechanisms
in soft tissue: involved in almost all of body’s metabolic processes

18
Q

magnesium

A

60-70% exists as the form of phosphorus and carbonates in bone, remaining is in cells
excess magnesium in cats has been implicated as a risk factor for struvite urolithiasis

19
Q

magnesium functions

A

cation in intracellular fluid
essential for cellular metabolism of carbs and protein
needed for protein synthesis, plays a role in muscle contractions and proper nerve transmission

20
Q

sulfur

A

largest proportion of sulfur found within proteins as a component of the sulfur-containing amino acids cysteine and methionine

21
Q

sulfur functions

A

helps transport amino acids across cell membranes

22
Q

iron

A

largest proportion found as a component of the protein molecules hemoglobin (<65%) and myoglobin (~4%)

23
Q

iron absorption

A

increased efficiency of iron absorption: low stores of iron in the body and increased metabolic need
factors that inhibit iron absorption: presence of phytate, phosphates, and oxalates

24
Q

copper

A

necessary for normal absorption and transport of dietary iron and essential for the formation of hemoglobin and for normal osteoblast activity during skeletal development
highest concentration found in liver

25
Q

zinc

A

widely distributed in body tissues
actions influence carbs, lipids, proteins, and nucleic acid metabolism
also a cofactor in synthesis of DNA, RNA, and protein
essential for normal cellular immunity and reproductive functioning

26
Q

zinc deficiences

A

usually associated with growth deficiencies in young animals
first clinical signs are usually skin and hair coat changes

27
Q

manganese

A

is a component of several cell enzymes that catalyze metabolic reactions
large proportion located in mitochondria
necessary for bone development and reproduction

28
Q

iodine

A

required for synthesis of hormones thyroxine and triiodothyronine
thyroxine stimulates cellular oxidative processes and regulates basal metabolic rate

29
Q

selenium

A

protects cell membranes from oxidative damage
can be toxic if excess amounts ingested

30
Q

cobalt

A

a constituent of vitamin B-12
no function identified

31
Q

chromium

A

a component of the organic complex known as glucose tolerance factor which enhances the action of insulin
has positive effects of supplemental chromium on glucose metabolism, insulin sensitivity, and immune responsiveness

32
Q

potassium

A

electrolyte
main cation in intracellular space
required for numerous enzymatic reactions, transmission of nerve impulses, and contraction of muscle fibers

33
Q

sodium

A

electrolyte
major cation found in extracellular fluid
helps maintain normal irritability of nerve cells and contractility of muscle fibers

34
Q

food

A

articles used for food or drink for man or animals

35
Q

drug

A

an article intended for the use in diagnosis, cure, treatment, or prevention of disease in animals and articles intended to affect the structure or any function in the body

36
Q

nutraceutical

A

portmanteau of nutrition and pharmaceutical applied to dietary supplements intended for specified therapeutic effects

37
Q

AAFCO

A

association of american feed control officials
independent organization that has been guiding state, federal, and international feed regulators with ingredient definitions, label standards and lab standards, while supporting health and safety of people and animals

38
Q

CVS

A

center for veterinary medicine
part of the FDA responsible for interstate regulation of animal food and drugs

39
Q

NASC

A

national animal supplement council
a trade organization comprising manufactures of dietary supplements for companion animals and associated industries

40
Q

FFDCA

A

federal food, drug, and cosmetic act
a law brought cosmetics and medical devices under control, and it required drugs be labeled with adequate directions for safe use

41
Q

DSHEA

A

dietary supplement health and education act
enacted in 1994
goals: ensure continued consumer access to a wide variety of dietary supplements and to provide consumers with more information about the intended use of dietary supplements
