Ascorbic Acid
別名: Vitamin C, Ascor L 500
> **Key Point**: Most dogs and cats naturally produce their own Vitamin C and do not require supplements unless specifically directed by your veterinarian. * **Guinea pigs** cannot make their own Vitamin C and must receive daily supplementation through a fortified diet or specific Vitamin C drops. * Store Vitamin C supplements in a cool, dark place, as the vitamin degrades quickly when exposed to light and air. * If your pet is prescribed high doses, monitor their stool; contact your veterinarian if diarrhea occurs.
劑量必須由獸醫按你寵物的個別情況決定。切勿在沒有獸醫指導下給予人類藥物或其他寵物的處方藥。
