What are the best vitamins & minerals for dogs & cats? Decoding your pet’s nutritional needs can feel like trying to read a food label in another language. But don’t stress, we’re here to help break it down in plain speak.
At PetWell, we believe in simple, purposeful nutrition rooted in real food and clean ingredients, because your pet deserves better than synthetic guesswork.
This guide covers the vitamins and minerals your dog or cat needs, why natural sources matter, and how to make sure their body can absorb every bit of goodness. 🐾
Why Do Pets Need Vitamins and Minerals?
Think of vitamins and minerals as your pet’s internal maintenance crew, they keep everything running behind the scenes: immune system, bones, coat, digestion, brain health, all of it!
When your pet’s missing key nutrients, things can start slipping. But when they’re fuelled properly? That’s when the real magic happens.
🌿 Why Natural Is Better. No Debate Here
Let’s talk about why natural, whole food–based vitamins absolutely beat the pants off synthetic ones:
✅ Higher Bioavailability = Better Absorption
✔️ Nutrients from real food are easier for the body to recognise and use.
✔️ Better absorption = better results = happier, healthier pets.
✅ Fewer Additives, Less Fuss
✔️ No weird fillers or preservatives
✔️ Less chance of allergies or digestive flare-ups
✔️ Cleaner ingredients that you (and your pet’s gut) can feel good about
✅ Nutrients That Play Well Together
✔️ Whole foods come packed with extra goodies like antioxidants and enzymes
✔️ Nutrients work in synergy (fancy word, but it just means they’re better together)
✔️ Boosts everything from immunity to coat shine, joint health and digestion. It even helps reduce anxiety and stress in your pets.

PetWell Tip: Our RELIEF Allergy + Skin + Coat supplement isn’t just loaded with superfoods, it’s crafted to support skin and coat, it’s gentle on tummies and boosts their immune system. No synthetic fluff, just real goodness.

PetWell Pick: Our DIGEST Gut Health supplement blend includes natural ingredients and enzymes that provides gut relief without the synthetic load.
Ever wonder if you can feed your dog human foods? We've got the answers in our blog: Can Dogs Eat Human Food?
🦴 Safe for Daily Use (No Guessing Games)
The problem with synthetic vitamins? They can build up in the body overtime and become toxic especially fat-soluble ones like A and D.
Natural, food-based nutrients are kinder to the body, and way safer for long-term use. You get what your pet needs , nothing dodgy.
💩 Better Digestion = Better Absorption
When your dog has a happy gut, everything just works better. Many whole food vitamin sources come with:
✔️ Natural fibre for smoother digestion
✔️ Enzymes that help break things down
✔️ Prebiotics to support gut flora
Combine that with our DIGEST supplement and you’ve got the perfect pair. It’s made with real food–based herbs and probiotics to help your pet absorb every bite.
🐕 Natural Taste Wins Every Time
If your pet’s a picky eater, good news: natural tastes better. Whole food–based supplements smell like food, not chemicals. That means:
✔️ Fewer battles over supplements
✔️ Less tablet rejection
✔️ More tail wags (and drool)
By choosing supplements with natural vitamins, such as those found in PetWell Supplements, you provide your pets with a more balanced and bioavailable source of essential nutrients, supporting their overall health and well-being.

🌏 Bonus: Better for the Planet
Less processing = lower environmental impact. Natural supplements skip the heavy manufacturing and come from more sustainable sources. So, you’re not just supporting your pet, you’re backing the planet too.
🎯 Bonus: Natural Support for Real-Life Health Stuff
Real food nutrients also help with things like:
✔️ Joint support (hello, green-lipped mussels and PetWell MOBILITY)
✔️ Inflammation and immunity (shout out to spirulina and moringa in PetWell
RELIEF)
✔️ Skin flare-ups and digestion (nettle, beetroot, oyster extract, also in PetWell
RELIEF)
We’ve designed every PetWell supplement to be packed with purpose, no fillers, just functional ingredients your pet’s body knows how to use.
🐾 Final Woof
When it comes to vitamins and minerals, natural just makes sense. Your pet deserves nutrients that work with their body, not against it. The kind that supports immunity, digestion, skin health, and energy, without adding stress or synthetic nonsense.
