Nutramax Cobalequin B12 Chewables (45 ct)
Nutramax Cobalequin is a trusted cobalamin supplement from a leading vet brand. The chewable tablets are small and flavored, so many cats take them like treats. Each tablet gives a steady dose of B12, and it also includes folate. This is helpful for cats who need support for gut health and red blood cell production.
I like Cobalequin for cats with soft stools or low appetite. It is also a great pick for cats with IBD or pancreatic issues when a vet suggests oral B12. The tablets crush well if your cat is picky. You can mix the powder into a spoon of wet food for easy dosing.
Pros:
- Vet-trusted brand with strong quality control
- Chewable and palatable for many cats
- Includes folate for extra metabolic support
- Easy to crush and hide in wet food
- Clear dosing for small pets and cats
Cons:
- Chewable form may not suit cats who refuse tablets

- Not a replacement for injections in severe deficiency
My Recommendation
Nutramax Cobalequin fits cats who need daily gut and energy support and who accept small chews. It shines for mild to moderate cobalamin support and for cats with diet-sensitive stools. If your cat prefers a “treat” presentation, this is a smooth win. In the Top 5 Best Quality Vitamin B 12 For Cats, it is my most balanced pick for quality, taste, and trust.

RX Vitamins B12 Liquid for Cats & Dogs (4 oz)
This RX Vitamins liquid provides flexible dosing for cats of all sizes. The dropper makes it easy to measure and to mix into food. Liquid B12 is a strong choice for cats who fight pills or chews. It is made for metabolic and nervous system support and to help appetite.
I found the liquid smooth to use in daily routines. A few drops can blend into a small spoon of tuna water. That keeps the dose simple and stress free. The large 4 oz bottle lasts a long time for single-cat homes.
Pros:

How I chose and why it matters
I picked and tested these products as of 2026 with a clear goal. I wanted safe, palatable Vitamin B12 options that are easy to use and backed by veterinary logic. Cats often need cobalamin when they have soft stools, poor appetite, weight loss, or chronic gut issues. Many senior cats also struggle with low energy. In those cases, B12 can make a calm but real difference. It can support appetite, mood, and how your cat feels day to day.
Vets often check serum cobalamin in cats with IBD, EPI, or pancreatic stress. If levels are low, many cats improve on a B12 plan. Oral forms help mild to moderate needs, while injections help severe cases. The Top 5 Best Quality Vitamin B 12 For Cats in this guide cover a range of forms. That means you can match your cat’s taste and health needs without guesswork. It also means you can start simple, then adjust with your vet as needed.
What to look for when buying B12 for cats
- Form: Chewable vs liquid. Choose what your cat accepts.
- Type: Methylcobalamin vs cyanocobalamin. Ask your vet if one is better for your cat.
- Added support: Folate or B-complex can help in some cases.
- Dosing clarity: Clear instructions and a good dropper or small tablet matter.
- Brand trust: Pick brands with vet input and quality control.
Giving B12 the easy way
I suggest you build a tiny “B12 ritual” each day. Use a small spoon of wet food, tuna water, or a lickable treat. Give the dose at the same time daily. Keep the serving small so your cat eats it all at once. If you use a chewable, try a quick praise and a pet right after. That turns the dose into a tiny win for your cat.
Safety notes and vet tips
Vitamin B12 is water soluble. It has a wide safety margin in cats when used as directed. Still, check with your vet before you start. If your cat has chronic digestive disease, ask whether to run a cobalamin test. Some cats need lab checks and timed re-doses. If your cat has not seen the vet for weight loss or vomiting, do that first. A smart plan pairs good testing with the right supplement form.
How these five compare in real life
Nutramax Cobalequin earns the top spot for taste and trust. RX Vitamins Liquid shines for exact dosing and long-term value. The B-12 Complex Drops help when you want broad B support in one bottle. The Methyl B-12 Liquid is ideal for nerve-focused plans. Jackson Galaxy B12 is perfect for trial runs, small spaces, and quick appetite support. This mix covers almost any home and any palate. That is why I chose them as the Top 5 Best Quality Vitamin B 12 For Cats.
Final shopping advice
If your cat accepts chews, start with Cobalequin. If your cat refuses solids, pick a liquid like RX Vitamins. If your vet wants methylcobalamin, go with the methyl B-12. For a gentle, broad boost, choose the B-12 Complex Drops. If you need a small bottle to test, use Jackson Galaxy B12. Any of these can help your cat feel better and eat more. The key is to pick the right form for your cat and to stay consistent.
