Why Do Cats Need Vitamins And Supplements?

Vitamins are involved in nearly every function of your cat’s body. Vitamins are essential for normal body functions, including growth, immunity function, metabolism and regulation. They aid in the breakdown of food, the production of energy, and the replication of cells. They collect harmful substances in order to protect the eye, prevent injury, make bones and preserve vision. They’re everywhere, all the time. All of these vitamins work together, and with other important nutrients, to get their jobs done. Vitamin E, for example, is required to allow your cat to absorb A. Calcium can be absorbed by the body through vitamin D. That means a deficiency in one vitamin can affect the production of the others and nutrients. That’s why it’s important to maintain a healthy balance of all the important nutrients in your kitty’s diet. Other common supplements include essential fatty acids, probiotics, and nutraceuticals. The essential fatty acids can be responsible for shiny hair, healthy immunity system and decreased inflammation. They also have effects on almost every system of the body. They’re often given to cats to decrease itchiness due to allergies or other skin issues and aid in the treatment of arthritis. Probiotics are key to healthy digestion. These are the good bacteria found in the digestive tract that break down food particles and produce useful byproducts like vitamins. These bacteria also protect against the growth of harmful, disease-causing bacteria. After some form of digestive upset or the administration of antibiotics, probiotics are often given to kitties to repopulate the digestive tract with the proper bacteria. Nutraceuticals are herbal or natural supplements, such as glucosamine. There is very little regulation or scientific research involved in nutraceuticals production, so beware and always consult your veterinarian before using it. Just because there is no research doesn’t mean they won’t provide some benefit, however. Nutriceuticals are often used to “treat” specific issues rather than be used as an everyday supplement for all cats.


Lysine supplements are most commonly given to cats with feline herpes. Cat herpes is different from the main form of herpes we hear about most often that is associated with people. This isn’t an STD.

It is an upper respiratory illness that causes sneezing, nasal discharge, and eye infections. This illness is highly contagious.

Lysine boosts your cat’s immune response to help them fight off and prevent herpes infections. Lysine is available in powder, gel and treats. If you are suffering from feline herpes, make sure to treat all your cats with Lysine supplements.

VetriScience has a nice high quality Lysine supplement to keep your pets’ immune systems up to snuff.

Fish Oil

Cats with a dull coat or dry, flaky skin benefit from fish oil. Fish oil is a great supplement for promoting healthy coats (just like for humans, actually). Plus, cats love it.

Check with your vet to rule out major health concerns as dull coats are sometimes a sign of more serious problems.

Fish oil makes coats shiny and lustrous. It also helps dry skin maintain moisture. The fatty acids in fish oil assists in the natural processes of your cat’s skin and coat. Fish oil supplements are great for cats with dandruff.

Fish oil’s essential fatty acid formula has more benefits than just your cat’s fur.

Keep an eye on your cat’s stools while trying to find the right dosage. Loose stools and upset stomachs indicate the dose is too high.

TerraMax Pro premium fish oil is our choice.

Nutri-Vet Multi-Vite Salmon Flavored Gel Multivitamin For Cats – Best Overall

Nutri-Vet Multi-Vite Salmon Flavored Gel Multivitamin For Cats is our choice as the best available vitamin and supplement for cats because it not only offers a good range of essential vitamins and minerals but it comes in a convenient and palatable gel.

You can give it as you like. Some cats love to lick the gel directly with their fingers, due to its natural fish flavor. Alternatively, you can mix it in with some wet food, or, for especially picky and selective diners, you can put it on the paw and the cat will clean or lick it straight off.

It contains vitamin B12, B6, B2 and Vitamin C. To make the gel more attractive, it is fortified in calcium, zinc and copper. You can give the gel to all cats, however, you need to consult your veterinarian before giving it to any cat that’s sick or on other medication.

Although it is a good all-round product, the gel can be flicked off paws and some cats are put off by the smell.

  • Includes vitamins A, B, C, and D
  • Gel is easy to administer
  • Excellent price
  • Gel can be flicked off paw without eating
  • Fish haters might be discouraged by strong smell

Vitamins and supplements are a part of our everyday routine. Have you ever thought if your cat would benefit from added vitamins and minerals?

Although your cat should be getting its daily nutrients from its diet, sometimes a commercial diet might miss sufficient amounts of vitamins and minerals for your cat to thrive.

A cat may need to have a different mineral in order to be at its best during certain life stages. For example, senior cats might benefit from a joint supplement as they age.

If you have regular visits to your cat’s veterinarian, they might advise on the best cat vitamins for your cat.

Do I need to give my cat vitamins every day?

Before you go ahead and make giving your cat vitamins a part of your daily routine, it’s best to speak with your vet first. It might not be necessary to give your cat vitamins each day. Not only is it a waste of money, but also it can be harmful for your kitty.

A cat will usually excrete excess vitamins through their body. Too many vitamins could be dangerous for cats. Vitamins A, D and E can be toxic for cats.

If your vet recommends giving your cat vitamins, be sure to ask how frequently to give them so that you can create a routine that works for you.

Rx Vitamins Rx D3 Liquid Immune Supplement

Rx Vitamins Rx D3 Liquid Immune Supplement is a liquid supplement that provides vitamin D3 to your cat.

Cholecalciferol, also known as vitamin D3, is a fat-soluble vitamin that is considered essential to cats. Vitamin D3 is stored in fat cells, so your cat shouldn’t be deficient if it is receiving adequate amounts through other food sources.

Vitamin D is a vitamin that humans get from the sun. Vitamin D is naturally absorbed by our skin directly from sunlight. The skin of cats is thicker than that of humans, so it cannot absorb vitamin D3 as well. Their skin does still create vitamin D3, and they ingest it when licking and preening their fur. This means that even indoor cats create some vitamin D3 from their skin, when they sit on the windowsill or collapse in the last sunny spot in the corner of the room, but they may need help ensuring that they get enough of it.

Rx D3 is a liquid so can be mixed in with food or syringed into the mouth. It only delivers a relatively small amount of vitamin D3 per drop, however, which means that this supplement may not be strong enough for a seriously deficient cat.

Vitamin D is important for calcium absorption and muscle movement. However, too much Vitamin D can cause poisoning. Please only supplement your cat in the cases and amounts prescribed by the veterinarian.

  • Tops up vitamin D3 in your cat
  • It is simple to combine liquid form with food
  • Expensive
  • A relatively mild dose of vitamin D3

Buyer’S Guide: How To Select The Best Supplements For Your Cat

Supplements and multivitamins serve the same purpose for cats as they do for humans. Supplements and multivitamins provide the vitamins and minerals cats need and they can be difficult to find in their daily diet.

It is a good idea to check with a vet before introducing a new vitamin or supplement to your cat’s diet, but if your feline friend has a deficiency in a certain vitamin, or you have been advised to offer a regular supplement, finding the right one is important. This means checking ingredients, determining the required level of the vitamin in question, and ensuring that it is palatable and easy enough to administer. Every cat is different, so while a particular supplement might be a good choice for one cat, there might be something better for another.

Why Cats Need Vitamins And Supplements

Some cats cannot process vitamins and minerals properly due to medical conditions.

Some people may require a boost in order to keep their coats healthy.

Supplements give them this boost.

Cat owners looking for natural or homeopathic alternatives to conventional medications find supplements helpful.

But remember, supplements are not a replacement for visiting your veterinarian. Your veterinarian will be able to recommend the best cat vitamins and supplements for you cat.

Your veterinarian is the best person to help you determine what your cat needs. He or she will help you come up with a dietary plan based on your cat’s overall health.

It is not recommended to attempt self-diagnosis of your cat. Unnecessary use of supplements could cause greater harm than good.

Here are a list of common cat supplements and vitamins that help treat common conditions to keep your cat healthy.

Our review process is unbiased and based on extensive research. We may be compensated if you make a purchase through one of the links.

Supplement and Vitamin Types

It is possible to buy supplements for almost any essential vitamin and mineral, but most fall into the following categories:

  • Vitamin B12: Cats can’t produce vitamin B12, but they need it for good health. Vitamin B12 must be obtained from food or supplements. Vitamin B12 supports digestion, nervous system and immune system. It also helps to preserve cognitive function. This vitamin is found in meat and liver. A diet that is lacking in substantial amounts of meat can cause a deficiency. Vitamin B12 requires multiple organs to help digest and use it, so any organ failure or illness can also lead to problems and require supplementation. Some cats are given vitamin B12 injections, but the body only retains vitamin B12 for a limited time, so injections need to be regular. You can give supplements daily, which may be cheaper and more convenient for your cat.
  • Vitamin D – Cats produce vitamin D in sunlight, just like people. While human skin absorbs vitamin D naturally, cat skin is thicker and covered with fur, which prevents it from occurring. While they get only a small amount of vitamin D from their food, the bulk of felines’ vitamin D intake comes from the way that they lick their fur. Vitamin D, which is fat-soluble and cannot be disposed off through the urine, is retained in the body. Vitamin D poisoning is possible if you don’t carefully monitor and check the levels your cat is getting. To ensure that safe levels are maintained, consult your veterinarian or follow the manufacturer’s instructions.
  • Omega Fatty Acids – Omega fatty acids reduce inflammation which, in turn, can reduce the pain caused by diseases like arthritis. These fatty acids are good for skin, and help maintain a cat’s hair. DHA is more important for cats than EPA. This contrasts with dogs. Some high-dose fatty acid supplements can give cats diarrhea and cause vomiting so don’t overfeed.
  • Probiotics: Probiotics, which are living bacteria that help to fight bad bacteria in the cat’s stomach. Probiotics come in many forms, each with its benefits and uses. You should research the benefits of probiotics before you buy them. This will ensure that your cat is getting what they need.
