Recently I was asked if I wasn't afraid of vitamin overdose--levels.
(1/1)
DeeDee:
I can't remember which post the question Lola asked was originally in, so I'm starting this thread.
Lola asked if I wasn't afraid of overdosing V & B by giving them vitamin supplements. I said, "No," but here's why. All the daily amounts of what they get:
Guaranteed Analysis Represents Minimum Levels Per Tablet of Vetriscience CANINE PLUS™ CHEWABLE TABLETS:
Moisture (max) 5.23%
Methionine 7.5 mg
Linoleic Acid (min) 3.75 mg
Calcium (1.92%) 75 mg
Phosphorus (0.96%) 37.5 mg
Potassium (0.01%) 0.375 mg
Magnesium (0.96%) 37.5 mg
Iron (1154 ppm) 4.5 mg
Copper (1.1 ppm) 0.0045 mg
Zinc (385 ppm) 1.5 mg
Iodine (15.4 ppm) 0.060 mg
Selenium (1.4 ppm) 0.00525 mg
Vitamin A 900 IU
Vitamin D3 75 IU
Vitamin E 7.5 IU
Thiamine (Vitamin B1) 7.5 mg
Riboflavin (Vitamin B2) 3.75 mg
Pantothenic Acid 7.5 mg
Niacin 7.5 mg
Pyridoxine Hydrochloride (Vitamin B6) 3.75 mg
Folic Acid 0.003 mg

*Cobalt 0.060 mg

*Ascorbic Acid (Vitamin C) 18.75 mg
*P-aminobenzoic Acid 3.75 mg
*Inositol 3.75 mg
*Lecithin 7.5 mg
*Betaine Hydrochloride 7.5 mg
*Pepsin (Pork) 6750 FCC Units1
*Protease (Aspergillus oryzae) 40.0 HUT Units2
*Bromelain (Pineapple) 1.35 GD Units3
*Lipase (Aspergillus oryzae) 0.375 FIP Units4
So, because I don't give the recommended dosage of 3 per day for Vlad and 2 per day for Barkly, those are the exact daily amounts Barkly (1 tab daily)gets, and just multiply x2 for Vlad (2 tabs daily) .
Now here are the limit amounts in this chart:
Daily Requirements for Canines

Pantothenic Acid, (B5) mg Minimum Requirement - 0.39; Recommended Daily Allowance - 0.49
Folic Acid, (B9) µg Minimum Requirement - 7.1; Recommended Daily Allowance 8.9
Biotin, (B7) aka, Vitamin H; For normal diets not containing raw egg white, adequate biotin is probably by microbial synthesis in the intestine. Diets containing antibiotics may need supplementation
Vitamin B12 (Cobalamine) µg Adequate Intake - 0.92; Recommended Daily Allowance - 1.15 Choline mg Minimum Requirement - 45; Recommended Daily Allowance - 56
Note:
Vitamin C, (ascorbic acid) The liver of cats and dogs have the key enzyme L-gulono-Y-lactone oxidase, ( EC 1.1 3.8 ), which is able to synthesize the needed ascorbic acid from glucose. The NRC warns against high intake of ascorbic acid, stating the following: "High intake of ascorbic acid may act as a prooxidant and induce lipid peroxidation." This includes Fenton's reaction, which will enhance iron absorption and cause a resulting overdose of this mineral. This reaction is reduced with an increase in Vitamin E levels in the diet. (page 234).
Note: Here you can see Vitamin C for Barkly would be 250 a day, and for Vlad would be 750 a day. They don't get anywhere near that much supplementation. http://www.natural-dog-health-remedies.com/vitamin-c-for-dogs.html
So that's why I don't worry about vitamin overdose. They never make it anywhere near the actual daily allowance whether it be human or animal.
*Remember to move the decimal point to convert grams to milligrams.
The decimal place is moved 3 places to the right.
0.1 g = 100 mg if you want to read it in micrograms
Kimberly:
Where can I get more information about this information?
DeeDee:
Except for the ingredients in their old vitamins (they don't have that formula anymore), I think I Googled it.
DeeDee:
I'd suggest reading this book to know what is really important:

Lola:
I THINK I asked that question because it seemed to me, that you added a bunch of stuff. NOT saying what you do/did was wrong! I have faith that you know what you are doing. I wouldn't.
