One value that defines our innovation: The dog and cat comes first. For over 40 years, Royal Canin has worked with breeder partners and veterinary nutritionists to go ever further into innovation and precision to enable us to formulate nutritional solutions which perfectly meet dogs and cats’ real needs.
From the time they’re born until well into their golden years, dogs’ nutritional needs are constantly changing and their food should too. That’s why we offer a full range of products designed for every dogs life stage.
From the time they’re kittens until they’re mature, cats’ nutritional needs are constantly changing and their food should, too. Your cat’s health matters, and that’s why we offer a full line of nutrition designed for every life stage as well as based on thier specific breed, lifestyle or special requirements.
FROM THE INDUSTRY
Because of its composition, a Royal Canin Health Nutrition food provides all essential nutrients measured out with utmost precision in order to contribute every day and on a long-term basis to the well-being and health of cats and dogs, according to their age, his size, his physiological condition and his breed.
Royal Canin is a global leader in pet health nutrition. In an industry that continues to adapt to popular trends, our mission remains the same: Observing them, learning from them, respecting them and recognising their differences is quite literally our life’s work. The goal of that work is to provide every dog and cat with the nutrition that is precisely right for their individual needs – needs that vary with the pet’s breed, environment, age, weight, gender, digestion, their genetic makeup and lifestyle.
Vitamin D is a group of fat-soluble vitamins responsible for intestinal absorption of calcium and phosphorous. Although vitamin D is commonly called a vitamin, it is not actually an essential dietary vitamin, as it can be synthesized in adequate amounts by most mammals exposed to sunlight. Cats and dogs however, cannot synthesise vitamin D efficiently and must receive it in their diet.Vitamin D was discovered in an effort to find the dietary substance that was lacking in a disease, namely, rickets, the childhood form of osteomalacia
A little background information
The rickets-fighting power of fish liver oil was discovered in 1782 and vitamin D was isolated in 1932. This liposoluble vitamin is provided in the diet. It is naturally synthesised by humans and herbivores by the conversion of skin sterols under the action of solar rays. To be active in the body it must be modified, first in the liver, then in the kidney.
Vitamin D toxicity is rare although hypercalcaemia is generally a good indicator of hypervitaminosis D. The main symptoms of toxicity include anorexia, nausea, and vomiting, polyuria, polydipsia, weakness, insomnia, nervousness, pruritus, and, ultimately, renal failure (as a result of calcium deposition within the renal medulla).
Vitamin D plays an essential role in the regulation of calcium and phosphorus metabolisms :
Vitamin D deficiency can cause:
Marine fish and fish oils are the richest natural sources of Vitamin D. Other sources include fresh water fish and eggs (particularly the yolks). Beef, liver and dairy contain smaller amounts of vitamin D.
