Pet Supplements & Vitamins

Pet Supplements & Vitamins provide targeted nutritional support to help keep your dog, cat or small pet healthy, active and comfortable at every life stage. From daily multivitamins for overall wellbeing to omega-3 oils for joints and coat, probiotics for digestion and calming formulas for anxious pets, our Pet Supplements & Vitamins collection at Welzo makes it easy to buy trusted pet nutrition products online.

What Are Pet Supplements & Vitamins?

Pet supplements and vitamins are concentrated nutritional products designed specifically for animals, not humans. They can help fill dietary gaps, support joints, skin, coat, digestion, immunity and behaviour, and are often recommended alongside a balanced diet and regular vet care. Many owners build their pet’s routine using core nutrition from our Welzo Pet Supplements range, then layer in additional support from Pet Supplements tailored to their animal’s age and needs.

Benefits and Features of Pet Supplements & Vitamins

Supports overall wellbeing – multivitamins and general health formulas help ensure key vitamins and minerals are available in the right amounts.
Joint & mobility support – supplements with glucosamine, chondroitin, MSM or omega-3 can help maintain joint comfort and mobility, especially in senior pets or large breeds.
Skin & coat health – essential fatty acids, biotin and other nutrients support healthy skin, reduce dryness and promote a glossy coat.
Digestive & gut support – probiotics, fibre and digestive aids help maintain healthy digestion and stool quality.
Calming and behaviour support – targeted blends may help promote relaxation in pets who are nervous, reactive or stressed, especially when used with products from our Pet Calming collection.
Life-stage targeted formulas – tailored options for puppies, kittens, adults and seniors support age-specific needs.

Why Are Pet Supplements & Vitamins Important?

Even with a good diet, pets can have changing nutritional needs due to age, breed, activity level, environment or underlying health issues. Joint stiffness, itchy skin, digestive upsets and low energy are common concerns that may benefit from targeted nutritional support. Pet supplements and vitamins provide an easy, measurable way to support these areas without changing your pet’s entire diet. They are especially useful for older pets, working or sporting dogs, pets recovering from illness and small animals with specific dietary requirements, alongside wider pet-care essentials such as Rabbit Care Supplies and other species-specific products.

How to Use Pet Supplements & Vitamins

Always choose supplements formulated specifically for your pet’s species (dog, cat, small animal) and weight range.
Follow the dosage on the label carefully; many products are dosed by bodyweight and can be sprinkled on food, given as chews or offered as liquids.
Introduce new supplements gradually, especially probiotics or new flavours, to minimise digestive upset.
Use supplements consistently over several weeks, as many benefits build up over time.
Monitor your pet’s behaviour, appetite, stool quality and mobility, and consult your vet if you notice anything unusual.
If your pet is on medication or has a diagnosed condition, check with your vet before adding any new supplement.

Research, Insights & Expert Information

Vets frequently recommend joint and mobility supplements for large breeds and senior dogs to help maintain comfort and movement.
Essential fatty acids (like omega-3) are widely used for skin, coat and joint support in both dogs and cats.
Probiotics are increasingly used to support pets with sensitive digestion, changes in diet or stress-related stomach upsets.
Supplements are intended to support, not replace, a complete diet and regular veterinary care.
Because pets metabolise nutrients differently from humans, only species-specific products should be used.

FAQs

Does my pet really need supplements?

Some pets do very well on a complete diet alone, while others benefit from extra support for joints, skin, digestion or general wellness. Supplements are especially common for seniors, large-breed dogs, active pets and animals with specific health needs.

Can I give my pet human vitamins?

No. Human supplements can contain unsafe doses or ingredients for animals. Always use products specifically formulated for your pet’s species and weight.

How long does it take to see results from pet supplements?

Joint and skin supplements may take several weeks of daily use to show full benefits. Digestive aids and probiotics can sometimes show effects more quickly, particularly for mild digestive upset.

Are pet vitamins safe to use long term?

Most pet multivitamins and key supplements are designed for long-term daily use at the recommended dose. However, pets with medical conditions should be monitored by a vet.

Can I use more than one supplement at a time?

Yes, many owners combine, for example, a multivitamin, joint supplement and probiotic. Make sure products do not overlap excessively in certain nutrients and ask your vet if you are unsure.

What’s the best way to give supplements to fussy pets?

Chewable treats, flavoured liquids and powders that mix with food are often easiest. You can also pair supplements with healthy snacks from our Pet Treats collection to improve acceptance.

Should I stop supplements before a vet visit or surgery?

Some supplements may need to be paused before surgery or procedures. Always tell your vet everything your pet is taking so they can advise you appropriately.
