The 9 Best Vitamins for Cats
1. Purina Pro Plan Veterinary Diets Digestive Supplement for Cats – Best Overall
| Type: | Powder |
| Primary Ingredient: | Dried Enterococcus Faecium |
| Size: | 30 servings |
Purina Pro Plan Veterinary Diets FortiFlora Powder for Cats is one of the best overall vitamins for cats on the market. This product aims to improve a number of different aspects of your cat’s health. Purina Pro Plan Veterinary Diets FortiFlora Powder Digestive Supplement for Cats tackles immune health, digestive health, and fur health. It contains ample amounts of antioxidants, probiotics, and vitamins. It has even been shown to help cats suffering from diarrhea. The two main types of vitamins found in this product are vitamin C (derived from L-Ascorbyl-2-Polyphosphate) and vitamin E. This is a great all-around product that is easy to feed by pouring a package onto your cat’s food once per day. You get a month’s worth of supplements per box.
The biggest downside is the price. This is one of the more expensive vitamin supplements per month and can really add to your cat’s food budget. Not everyone will be willing or able to afford to put their cat on this regularly.
- Tackles multiple parts of your cat’s health
- Includes large amounts of Vitamin C and Vitamin E
- Easy to feed food topper
- Excellent formula from Purina Pro Plan
- Can help cats that suffer from diarrhea
- Can be expensive to use long term
2. Pet Naturals L-Lysine Cat Chews – Best Value
| Type: | Chews |
| Primary Ingredient: | L-Lysine |
| Size: | 60 chews |
Pet Naturals L-Lysine Cat Chews is a supplement aimed at cats with immune deficiencies or cats that are aging and are more prone to getting sick. These chews contain L-Lysine, which is an essential amino acid that helps keep your cat’s body running at its best. It also contains oat flour and rye flour. Oat flour contains good amounts of vitamin A, while rye flour contains a B vitamin complex. The result is a chew that gives your cat a ton of great benefits in one simple treat. The treats are even shaped like little fish. Pet Naturals L-Lysine Cat Chews are excellent for cats of all sizes and all ages. Many cat owners who have cats suffering from feline herpes (very common) use this supplement as an immune booster!
These treats were recently reformulated. They used to be molasses flavored, but now they are chicken liver flavored. The chicken liver smell is strong and unpleasant for some people to handle. And, this is not a multivitamin, so it may not be suitable if you’re trying to maintain your cat’s overall health. However, we still think these are the best vitamins for cats for the money, especially if you want to help keep your cat’s immune system in great shape.
- Potent immune supplement
- Amino acids, vitamin A, and vitamin B complex all present in large amounts
- Easy to feed chews
- Good quantity for the price
- Chicken liver treats don’t smell great
- Not a multivitamin; better for cats with immune deficiencies
3. Fera Pet Organics Probiotics for Cats – Premium Choice
| Type: | Powder |
| Primary Ingredient: | Organic Acacia |
| Size: | 2.5 ounces |
One reason that people give their cats vitamins is to help boost their gut health and digestive system. Many cats have digestive issues, including vomiting and loose stools. Fera Pet Organics Probiotics with Organic Prebiotics for Cats helps bolster cats’ gut health with a slew of natural ingredients, including billions of CFUs of microorganisms. The most potent vitamin in Fera Pet Organics Probiotics with Organic Prebiotics for Cats is vitamin E. This supplement includes 10 IU of vitamin E. You just need to use one small scoop of this powder per day to help improve your cat’s digestive health with potent vitamins and probiotics.
The only problem with this product is that it is formulated for both dogs and cats. Anything that is made for both cats and dogs (two very different species) may not be as effective as a product made for one or the other.
- Potent probiotic
- Easy to feed powder
- A large amount of helpful Vitamin E
- Tub will last quite a while
- Not specially formulated just for cats
4. The Missing Link Ultimate Feline Superfood
| Type: | Food topper |
| Primary Ingredient: | Ground Flaxseed |
| Size: | 6 ounces |
If you have trouble getting your cat to eat treats or solid supplements, you should try a food topper. This food topper is a simple powder that you add to your cat’s food so that they can get a blast of vitamins and nutrients with their meal.

You can add all of these benefits to your cat’s diet with just a little bit each day. Missing Link Ultimate Feline Superfood promotes skin, coat, digestive and immune health.
Some people think that flax seed, one of the primary ingredients of this supplement, is not suitable for cats, but that is not the case. Flax seed is perfectly safe for cats. The Missing Link Ultimate Feline Superfood is National Animal Supplement Council (NASC) certified.
- National Animal Supplement Council (NASC) certified

5. VetriScience Nu Cat Senior Soft Chews Multivitamin for Cats
| Type: | Chew |
| Primary Ingredient: | Oat flour |
| Size: | 30 chews |
VetriScience Nu Cat Senior Soft Chews Multivitamin for Cats is a multivitamin specifically aimed at aging cats. Some cats can live for an incredibly long time and giving them a vitamin to promote their health as they age will help keep them around longer. These chews do that by providing a laundry list of supplemental nutrients, including ample amounts of vitamins. VetriScience Nu Cat Senior Soft Chews Multivitamin for Cats include vitamin A, vitamin D3, vitamin E and vitamin B12. These vitamins go along with a host of minerals, omega-3s, and amino acids to promote immune, heart, liver, eye, and brain health in elderly cats. This pack includes 30 chews, which should last a whole month.
The biggest downside to these chews is that they sometimes crumble into small pieces in the package, and they can also be smelly. Overall, these are relatively minor gripes, but they should be noted.
- Specifically formulated for senior cats
- Tons of vitamins and minerals in one simple chew
- Affordable price
- Tons of varied health benefits

They are also made in the United States to help ensure consistent quality. They are also surprisingly affordable.
One of the only consistent complaints surrounding the cat formulation was that sometimes the treats seemed dried out. When dried out, the chews get hard and tough to chew, which can hinder your cat’s ability to eat them.

- Made in the United States
- 10 different vitamins included

- Treats can get hard and dried out
7. PetHonesty Dual Texture Hairball Support Chews Supplement for Cats
| Type: | Chew |
| Primary Ingredient: | Citrus pulp and apple pomace |
| Size: | 3.7 ounces |
Some cats struggle with hairballs. Some cats cough up hairballs a lot, and other cats let hairballs build up until they are extremely large and disruptive. One way to help your cat deal with hairballs is to give them a vitamin supplement that facilitates the passing of these gross objects. PetHonesty Dual Texture Hairball Support Chews Supplement for Cats uses natural fruit byproducts to give your cat a boost of vitamin C and vitamin A with the goal of causing hairballs to pass easier and break down faster. The main ingredients of these vitamin supplements are Citrus Pulp, Apple Pomace, Psyllium Husk, Zinc Methionine, Omega-3s. The fruit provides your cat with plenty of vitamins, and the psyllium gives a boost of fiber.
Feedback from regular users reports that these vitamin supplements actually work in reducing the number and severity of hairballs in cats. However, some cats refuse to eat them. That is to be expected as cats are generally pickier than dogs, but it is still disappointing when it happens.
- Natural source of vitamins and fiber
- Helps reduce and eliminate hairballs
- 30-day supply for one affordable price
- Some cats refuse to eat these treats
8. Nummy Tum-Tum Pure Pumpkin Canned Cat Food Supplement

All you have to do is give your cat a can of Nummy Tum-Tum Pure Organic Pumpkin Canned Dog & Cat Food Supplement in addition to their regular food and be done with it.
The biggest downside of Nummy Tum-Tum Pure Organic Pumpkin Canned Dog & Cat Food Supplement is simply the cost. It can get pricey to add this to your cat’s regular diet, even though it is easy and effective to do so.

Buyer’s Guide: Choosing the Best Vitamins For Your Cat
Do Cats Need Vitamins?
Not all cats need vitamin supplements. If you feed your cat a well-formulated diet and your cat does not have any underlying health issues, they should get most of the vitamins that they need. However, some cats have deficiencies that can manifest in things like fur loss and weight loss. In these cases, you might want to consider a vitamin supplement. If you are curious, you should ask a veterinarian. They will be able to point you toward a vitamin supplement that is right for your cat.
Not all cats need vitamins. But extra vitamins and minerals won’t hurt your cat if you want to try to give them a little boost. The decision of whether to give your cat vitamins is up to you and should be made by you with input from the veterinarian.
Vitamins vs. Supplements
Many supplements have vitamins in them, but not all of them do. If you are specifically looking to give your cat vitamins, you need to make sure that the supplements you are considering actually contain vitamins. Vitamins are given almost entirely via supplements, but not all supplements have vitamins in them. Some supplements only contain amino acids, probiotics, or fiber and do not contain measurable amounts of vitamins. Always look at the ingredient list and always check the nutritional facts before buying and feeding your cat supplements of any kind.
Getting Cats to Take Vitamins
Getting your cat to eat a supplement can be a challenge. Some cats do not like the smell or taste of supplements. You might need to try different types of supplements to help get your cat the vitamins they need. Many vitamin supplements come in chews that you feed like treats. Others are powders that you give as a food additive, which helps them blend in with their normal meal. Other vitamins are baked into regular dry food or wet food that you feed normally. Finding the type of vitamin supplement that your cat will eat regularly can be tricky, but once you find one that your cat likes, you should have no problem feeding them.
Consider Your Budget
Some vitamin supplements can be expensive. Be sure to consider your budget and also consider how often you will need to feed your cat the vitamins. If you plan on feeding your cat extra vitamins every day, you will need to consider how often you will need to rebuy or refill your supplies. Some prices look good up front, but if you need to buy the product weekly or monthly, it can add up quickly. Don’t get blindsided by recurring costs or by small quantities when buying and make a budget upfront before investing in something long term.
