5 Best Cat Supplements and Vitamins – Veterinarian Recommended

Like humans, pets do not always get all the essential vitamins and minerals required from their diet. Since they cannot express their needs, it becomes difficult to know if an extra boost of nutrition is needed unless faced with health conditions or nutritional deficiencies.

Cats can benefit from extra immune support through supplements, especially those on a raw diet, ensuring they receive essential micronutrients.

Supplementation depends on your cat’s health, life stage, and diet. While supplements should complement, not replace, veterinary care, they can support overall health.

Choosing the right supplement can be challenging, but this review helps guide you in selecting the best options for your cat’s needs.

What Are Cat Vitamins and Supplements?

Cat vitamins and supplements are specially formulated products designed to enhance your cat’s nutrition, supporting overall health and well-being.

Just like humans, cats sometimes need additional nutrients that might not be adequately provided by their regular diet. These supplements can include vitamins, minerals, probiotics, and other nutrients that support specific health needs, such as joint health, digestion, and skin condition.

With a variety of supplements available, cat owners can address specific concerns like weight management, immunity, and skin health, helping their cats live a healthier and more active life.

Key Ingredients Present in Best Cat Supplements and Vitamins

Here are some of the key ingredients to be on the lookout for when settling for the best Cat Supplements and Vitamins:

Omega-3 Fatty Acids

Omega-3 fatty acids have anti-inflammatory properties, making them ideal for cats with allergies. They reduce shedding, promote a shiny coat, and support joint health, especially in cats with arthritis. A study published in 2021 states that cats who received Omega-3 had better movements, such as navigating stairs, than those who did not receive oil with Omega-3.^[1]

Vitamins B12

Vitamin B12, found in meat, fish, eggs, and liver, is essential for cats as they cannot produce it. It supports digestion, nervous function, cognition, and immune health. A research conducted on Vitamin B12 in cats indicates that it is an essential catalyzer for nucleic acid and hematopoiesis and also necessary for cell growth and function.^[2]

Glucosamine

Glucosamine helps in the treatment of joint problems in cats.^[3] It ensures a cat’s cartilage remains in good condition and prevents breakage. Supplementation of glucosamine also helps in the treatment of urinary tract disease.

Probiotics and Digestive enzymes

Probiotics are live bacteria that promote a good balance of microbiomes in the intestines.^[4] A microbiome supports the digestive system’s immune health and reduces inflammation. Digestive enzymes help in digestion and enhance the pancreatic function in cats.
