why vitamins and minerals matter in pet food
Here’s a basic rundown of the vitamins and minerals that your pet needs to help their bodies be happy and healthy. Have questions about your unique pet’s diet? Your veterinary team is here to help.
Vitamins and minerals help your pet’s body function right.
A big part of keeping your pet happy and healthy is a quality diet with the right balance of essential nutrients, including important vitamins and minerals that enable incredibly important actions inside your pet’s body. They help your pet get energy from food, provide antioxidant support, enable cells to communicate with each other, allow nerves to send messages to the brain, provide tools to build healthy bones, and much, much more.
A quality pet diet should provide all of the important vitamins and minerals your pet needs, without supplements. Don’t worry if you don’t see each one specifically called out in an ingredient list — many of these nutrients typically come nested inside a more complex food ingredient, which may provide more than one benefit for your pet.

Vitamins are valuable for pet health and nutrition
Water-soluble (hydrosoluble) vitamins
Water-soluble (hydrosoluble) vitamins dissolve easily in water, which means your pet will normally pee them out when their body is done with them.
The list of essential water-soluble vitamins includes B vitamins, choline and inositol, folic acid, and many more. Each one does something just a little bit different (but equally amazing) for your pet.
See common water-soluble vitamins
Choline and Inositol
This dynamic vitamin duo works together to build cell membranes and helps to protect your pet’s skin from dehydration. As a solo hero, Inositol also plays a role in nerve conduction.
Niacin
Niacin helps with skin health and to give your pet a glossy coat. It also works beneath the surface to help break down sugars and fats into energy.
Vitamin B1: Thiamine
Think energy and brain function. Thiamine generates energy for your pet’s cells and helps to move sensory impulses between neurons in the nervous system.
Vitamin B2: Riboflavin
Riboflavin-rich pet foods help boost your BFF’s skin health and to let them turn fat into energy.
Vitamin B5: Pantothenic acid
Vitamin B5 is a part of coenzyme A, a crucial component of metabolic reaction, otherwise known as all the processes that create energy for your pet’s cells.
Vitamin B6: Pyridoxine
Vitamin B6 is another coenzyme power player for creating energy inside your pet’s cells, specifically for amino acid metabolism.
Vitamin B8: Biotin
Much like niacin, your pet’s body uses biotin to increase skin and hair health. Biotin also supports a healthy nervous system by breaking down glucose, fatty acids and some amino acids.
Vitamin B9: Folic acid
Folic acid helps to synthesize DNA as part of the cell multiplication process. Fetuses need a lot of folic acid, so it’s easy for pregnant people and pets to develop a B8 deficiency.
Vitamin B12: Cobalamin
Another cellular power player! Vitamin B12 is another vitamin that helps at a cellular level for protein synthesis. It also fights against anemia and boosts red blood cell production.
Vitamin C
While vitamin C is a must for humans, it’s not actually an essential vitamin for dogs or cats. Typically, pets only need vitamin C in their diet when their own livers can’t produce enough to deal with issues like age, cell stress, and joint issues like arthritis.
Fat-soluble (or liposoluble) vitamins
Fat-soluble (or liposoluble) vitamins can’t be flushed out as easily as water-soluble vitamins. This means they can easily build up in body tissues and become dangerous at high levels, resulting in other health issues for your pet.
Vitamin A, vitamin D, vitamin E, and vitamin K are all fat-soluble vitamins that do really good things for your pet’s body. Your veterinary team can help advise you on the best ways to make sure they’re in your pet’s diet in the right amounts.

Vitamin A
Vitamin A is essential for vision and skin regeneration, and is what helps your cat or dog see in the dark. Pets with a vitamin A deficiency are susceptible to eye problems, skin problems, infections and pulmonary complications.
Vitamin D
Vitamin D increases the intestinal absorption of calcium and phosphorus, optimizes calcium bonding, and reduces the loss of calcium and phosphorus in the urine. The upshot? Vitamin D helps your pet avoid rickets, fractures, and joint issues.
Vitamin E
Vitamin E is crucial to helping your pet’s immune system fight oxidation, plus age-related conditions like heart disease, cataracts, and neurological diseases. Pet food labels may contain vitamin E in oils, oleaginous grains, or cereal germs.
Vitamin K
Vitamin K enables many enzymes essential for proper blood coagulation. Without it, pets can suffer digestive, nasal, skin and cerebral hemorrhages, and anemia. If your pet has dangerously low levels, they may even require an emergency vitamin K injection.
Magnificent minerals support major life functions
Macro elements
Macro elements are minerals that your pet needs in larger quantities to support healthy functioning.
See common macro elements
Calcium
About 99% of calcium in your pet’s body is in their bones, where it’s crucial for a strong skeletal structure and information transfer between cells. It’s especially important for puppies and kittens as they grow, and is often seen in tandem with other minerals, like phosphorus, to make sure pets get the good stuff they need.
Iodine
A minor metal, iodine plays a significant role in your pet’s digestive system and helps with the synthesis of thyroid hormones that regulate your pet’s metabolism.
Magnesium
Magnesium is a multifunctional mineral that helps to build your pet’s bones, produce energy at a cellular level, and enable a good working nervous system.
Phosphorus
When balanced with calcium, the two minerals work together to maintain bone structure and cell energy. Your veterinary team will let you know if your older dog needs a diet with less phosphorus, to avoid complicating existing health conditions.
Potassium
Potassium is called a macro mineral, because the body needs large amounts to balance it with sodium for proper cell functioning and energy creation.
Potassium citrate
Potassium citrate helps to bond with calcium in your pet’s system, helping to reduce urine acidity and prevent painful kidney stones.
Sodium
Sodium helps to monitor the pressure inside and outside of your pet’s cells. And, since it encourages your pet to drink more water, it also encourages your pet to pee and clear out minerals that might otherwise form kidney stones.
Sodium phosphates
Sodium phosphates help slow down the formation of tartar, the dental-disease-causing crust created by old plaque on pet teeth.
Trace elements
Trace elements include copper, iodine, iron, manganese, selenium, and zinc. Your pet only needs small, or trace, amounts of these minerals for optimal health. Trace elements may also be called chelated trace elements, or be included under “purified salts.”
See common trace elements
Iron
The small amounts of iron your pet needs are vital for bodily function, like helping to provide oxygen to both organs and muscles.
Copper
Copper helps with several functions in your pet’s body, helping their systems absorb iron and stop anemia. Plus, it’s part of melanin synthesis, which is what ultimately gives your pet his or her hair color.
Manganese
Especially important for puppies and kittens, as well as older pets, manganese helps ensure quality bone and cartilage. It also helps with mitochondrial function to provide energy.
Selenium
Selenium acts as an antioxidant to help fight against oxidative stress, which includes aging, pollution, cancer, or inflammatory diseases. Selenium also acts in tandem with vitamin E to protect cell membranes from free radicals.
Zinc
This mineral can help boost your pet’s body function, including the quality of their skin and hair and reproductive function.
When does my pet need vitamins and mineral supplements?

If you’re feeding your pet a quality diet, you really shouldn’t need to give them supplements. Quality pet food is designed to provide all the vitamins and minerals your puppy, kitten, dog, or cat needs. Plus, adding unnecessary vitamins or minerals to your pet’s diet can create a nutritional imbalance and actually be harmful to your BFF.
If you’re concerned about special needs — like picking a puppy and kitten diet to support your little one as they grow — reach out to your veterinary team. We can help you navigate the pet food aisle and pick a chow with the right balance of calories, calcium, iodine, and other good stuff for the pet you love.
