They create the best cat supplements, based on a formula resulting from research, feed the
cats, and monitor their response to the diet through many health tests. In this way, they get a
complete picture of the effect that the dietary formula has on the cat’s body. The best pet food
companies conduct food studies before launching a new product.
All this is because the most loved pets and the most frequently found in people’s homes are
without a doubt, cats and dogs. Besides the provided food, they also need vitamins and
minerals for the good internal and external functioning of the body.
Vitamins are necessary for growth, appetite, and proper digestion, as well as development,
having an essential role in healthy skin, teeth, and bones.
Unfortunately, there are very few companies that conduct food studies. Most, simply develop
diets based on a formula, package, and sell them without ever feeding actual cats. But about
why and how we have to supplement the cats’ diet with supplements and vitamins, we’re going
to talk more in the buyer’s guide.
To take care of your animals, in our article we will offer you a wide range of vitamins and
minerals. We have products such as powder, capsules, tablets, gel, and oil. So let’s begin our

To select the best cat supplements from so many brands and varieties of cat food, we need
to do research based on valuable information.
In general, large pet food companies that produce and sell large quantities worldwide are more
reliable than unknown ones, but this is not a rule. We may not find the ingredients written on the
label in the food’s content.
But the big companies develop the diet formulas using food studies based on the special needs
of different breeds, life stages, and health status, so we can have greater confidence.
As we said in the beginning pet food manufacturers will create a diet based on the cat’s life
stage and lifestyle. A growing kitten has very different nutritional needs than an adult cat.
Many pet food companies produce foods designed to meet the nutritional requirements of “all
life stages” to cover a larger market segment. That means the formulas do not meet the dietary
needs of one age group, not to mention the differences between races.
Once you’ve chosen a diet developed with respect for the animal and is ideal for your cat’s
stage and lifestyle, there are some supplements you can consider based on your cat’s special
You should always discuss with your vet any supplements you plan to give your cat. This will
ensure there are no health complications or interactions with other medications you are giving or
medical conditions your cat has.
If you choose a multivitamin or a single specific nutrient, please be aware that adding them
to a complete, balanced diet can combine with nutrients already in the food and create toxicity.
What is certain, according to veterinarians from the American Veterinary Medical
Association (AVMA), good quality vitamins and supplements, administered on time, ensure a
long and healthy life for cats.
Types of cat supplements
General vitamins and minerals
A variety of best cat supplements, such as single or multivitamin products are available for
cats. Most cat foods contain all the vitamins and minerals a cat needs. But when the cat’s diet
consists of homemade food or that bought at the pet shop on the corner, we must consider
adding them to the daily ration.
Essential fatty acids
Omega-3 and Omega-6 fatty acids, administered for their quality, keep a clean and shiny
coat and prevent hair loss. It also protects your cat’s immune system, liver, eyes, brain, and
joints. And, just like in humans, Omega-3s boost heart health and fight high cholesterol.
Probiotics are healthy, “good” bacteria that help improve digestive health. They contain
microorganisms such as Lactobacillus acidophilus or Lactobacillus casei (also found in some
yogurts), which control the overpopulation of “bad” bacteria in the large intestine.
They are herbal remedies that fall into a gray area between pharmaceutical products and
supplements. The most famous are:
Glucosamine and chondroitin
We give together these to help protect the joints to prevent or slow the progression of
arthritis. These work to increase lubrication within the joint and repair the cartilage. They won’t
eliminate arthritis or correct structural abnormalities, but they can help support movement
Milk thistle extract or silymarin (the thistle with purple flowers)
Helps eliminate toxins from the cat’s liver. We can use it for cats with liver disease.
5 reasons to use the best cat supplements containing
vitamins, minerals, and other active elements:
1. In the case of arthrosis or joint problems, supplementation with vitamin C, chondroitin, GAg (Group
Antigens), and other active elements can lead to a reduction in joint inflammation, increased
comfort, and improved mobility. In the case of dermatoses, supplementing the supply of
essential fatty acids, omega-3, and 6, can lead to a decrease in itching and an improvement in
2. Because kitty is growing. With growing cats, an additional intake of calcium, magnesium,
phosphorus, and vitamin D is necessary, in certain concentrations relative to each other, to help
the harmonious growth of bones.
3. In the case of acute diseases. Severe diseases can lead to a decrease in the body’s ability
to feed itself, to produce many vitamins on its own, and above all, to record an exaggerated
4. After antibiotic treatments. We know that the bacterial flora in the intestines of animals
handles the “production” of some vitamins needed by the body, and antibiotics destroy these
“little factories” of vitamins.
5. Has an irregular diet, deficient in nutrients. You may think that what you prepare for them
at home is ideal, and they eat very well. It is normal and well known that you put your love and the best feelings for your cat when you prepare the meal. We could only say that you can use them
as a “safety net” in the unlikely event that some chemical element necessary for good body
maintenance could be missing.
5 reasons NOT to give food supplements to your cat without
the recommendation of a specialist veterinarian:
1. Some of the vitamins are already produced in the animal’s body. The bacteria synthesize
vitamins from the B group and vitamin C in the intestine. An excess of vitamin B could lead to an
increased risk of neoplasia or lead hyperexcitability. Excess vitamin C can lead to changes in
the pH of the urine and can lead to the appearance of lithiasis problems.
2. Several of the vitamins can accumulate and become toxic. For example, vitamins D and A
can accumulate in the fatty tissue of animals and can even cause intoxication.
3. There are variety of foods with the best cat supplements can aggravate diseases such as kidney
failure or certain forms of cancer.
4. Dietary supplements can cause digestive disorders.
5. Food supplements for human use are not recommended for dogs and cats, same as
those for dogs are not used for cats, and vice versa. The balance between the constituent
elements in each product, their doses are different from species to species and their
administration can lead to disorders that are difficult to diagnose.
Supplements that should be avoided or administered with
Experts say that supplements containing:
Garlic: destroys red blood cells, leading to anemia
Onion: destroys red blood cells, which leads to anemia
Calcium: too much can be toxic
Vitamin D: too much can be toxic
Vitamin C: Too much can cause urine to be too acidic, which can lead to crystals forming and
blocking the sanitation system
Do cats need the best cat supplements?
Healthy cats with a complete diet do not need nutritional supplements. Introducing
supplements can throw their diet off balance and cause problems. Supplements in high amounts
can be harmful to cats as they cause digestive problems and should only be given on the advice
of a veterinarian.
What supplements should the cat’s diet contain?
Cats are carnivorous animals that rely on the proteins found in meat to grow harmoniously
and be healthy. Cats evolved from hunting animals that usually eat a lot of protein, moderate
amounts of fat, and a moderate amount of carbohydrates. In addition, compared to dogs or
humans, cats need more protein in their daily diet.
At the same time, cats also need other nutrients, including vitamins, minerals, fatty acids,
and amino acids. Cats should also have fresh, clean water at all times.
In addition to protein, cats can eat fruits and vegetables, but some are easier to digest than
others. Kittens instead, have sensitive stomachs and need special nutrition to grow up healthy,
strong, and full of energy.
What oils are safe for cats to consume?
A few common oils that are the best cat supplements and safe to use are fish, cod liver,
hemp, flaxseed, krill, coconut, and sunflower oil. However, large quantities of sunflower oil (or
any oil) can cause diarrhea. Over time, your cat will become fat so don’t feed it too much. The
same applies to fish cans like sardines in oil, which are slightly better but still shouldn’t be
consumed in large quantities.
If we feed the cats with the best cat supplements like premium, original food, such as Zesty
Paws Salmon Oil, produced by serious companies, supplements and vitamins should be
administered only in certain cases, periods of life or to increase the state of health.
If the diet consists mainly of food prepared at home or bought from local pet shops, it is good to
consider the administration of vitamins and supplements to keep the cat healthy for as long as
