Thailand may be a paradise for us, but many things here, like bacteria, viruses, and parasites, can jeopardize our cat’s health.
Because of this, sometimes our furry friends need a little health boost.
Cat supplements can help fill nutritional gaps, boost immunity, and keep our kitties feeling their best.
But are all cat supplements on the market worth it? And more importantly, are they high quality?
To help you navigate the world of cat nutrition, I’ve compiled a list of the seven best cat supplements you can find in Thailand.
As I always write from my personal experience, the following cat supplements are ones I’ve used on my cats and had positive results with.

Should Cats Take Supplements?
If you look at the package of most cat food products, you will see that many have added vitamins and minerals.
So if high quality cat food is designed to meet all a cat’s nutritional needs, the question arises: do cats really need supplements?
It depends.
If your cat is totally healthy, there is no need to give them additional supplements. Their clean slate of health suggests that their diet is meeting all their nutritional needs.
However, if your cat has specific health problems, gets sick frequently, or is prone to issues like chronic diarrhea or UTIs, supplements are a good idea.
Young kittens can also benefit from supplements, even if they appear healthy. This is because their immune systems are still strengthening, making them more vulnerable to illness.
So, let’s talk about the supplement options available to cats.
If you’re wondering, ‘Can cats have human supplements? ‘ The answer is NO, as they may contain harmful ingredients to cats.
Moreover, there is no need to give cats human supplements as there are many excellent supplements designed specifically for felines.
Let’s take a look at some of the best cat supplements available through vets in Thailand and online stores, such as Lazada.
Best Cat Supplements For Kittens
Taurine

Taurine is an essential cat supplement that helps to maintain a healthy immune system, digestive system, heart function, and normal vision.
As taurine is added to most cat foods, most adult cats do not need these supplements.
However, taurine supplements can be helpful for kittens, especially orpahns, as taurine plays a crucial role in healthy growth and development.
If you give your kitten taurine supplements, I recommend Felovet, which contains both taurine and lysine, an essential supplement for immune support.
You can feed this gel directly to your kitten or mix it in their food.
Iron

I’ve fostered many orphaned neonatal kittens that had anemia.
Anemia is prevalent in young kittens living outdoors and results from a severe flea infestation.
In young kittens, the parasites can suck blood from their body faster than it can be replaced. This depletes their red blood cells and, over time, leads to anemia.
So, if you’ve rescued a young kitten covered in fleas, it’s a good idea to give them iron supplements.
There are two types of iron supplements for cats – gel or liquid.
Irosine is my go-to option as it contains:
- Iron (for blood support)
- Taurine & Beta-Glucan (for growth & development, as explained above)
- Lysine (for immune support)
- B Vitamins & Folic Acid (to promote appetite and cell repair)
Another option is Pettonic Plus, a liquid iron supplement. Pettonic Plus contains various vitamins and minerals to nourish the blood, such as:
- Iron
- Copper amino acid
- B Vitamins
- Folic acid
- Beta-glucan
Severe anemia can cause fatigue in kittens. So, besides iron supplements, consider giving them a high-energy nutritional supplement, like Nutri-plus gel.
Nutri-plus gel helps kittens and cats regain energy after illness and can stimulate their appetite. I often use this supplement for underweight and malnourished kittens I’m fostering.
Best Cat Supplements For Constipation & Diarrhea
Synbiotics

Both probiotics and prebiotics are essential for digestive health, and are particularly important when a cat is dealing with gut issues like constipation or diarrhea.
Probiotics increase the number of beneficial bacteria in the gut, while prebiotics act as food for this good bacteria.
Whenever one of my cats or foster kittens has digestive problems, I add synbiotics to their food.
Synbiotics are a combination of probiotics and prebiotics. There are a few different cat synbiotics you can get, but I use this one by Pawly.
You simply sprinkle the capsule contents over wet food. And unlike some supplements, they don’t have an unpleasant smell or taste.
Electrolytes

If your kitty has severe diarrhea or is vomiting due to stomach issues like a bacterial infection or worms, I highly recommend giving them electrolytes.
Electrolytes’ primary purpose is to replace the fluids lost from diarrhea and vomiting, preventing dehydration. This helps to ensure the normal functioning of cells, tissues, and organs.
In addition, electrolytes can help to:
- Maintain healthy muscle and nerve function.
- Boost heart health
- Help your cat recover from fatigue due to illness
I use Petme-Lyte, which contains added vitamins, amino acids (including taurine and lysine), and prebiotics.
So, how do you give a cat electrolytes?
There are a few different ways:
- Adding electrolytes to a bowl of water (check the packet for the ratio)
- Adding electrolytes directly to wet food (I also add a bit of water and mix it together)
- Syringe feeding electrolyte mix (this is the best option for cats that are refusing to eat or drink)
Best Vitamin For Cats Immune System – Lysine

If your cat comes down with the common cat flu, reach for the lysine supplements.
Lysine boosts immunity and can help lessen upper respiratory symptoms like congestion, sneezing, and runny nose. This is because lysine slows down the replication of feline herpesvirus, one of the viruses that causes cat flu.
Whenever I have cats or kittens with cat flu, I immediately start them on lysine supplements, and I see the difference it makes.
Moreover, when one cat gets sick, I give all my other cats lysine to reduce their chances of catching it.
While you can find lysine in many cat supplement gels, I recommend opting for the tablet form when treating cat flu. My vet prescribes this one by Intervetta, which you can also buy on Lazada.
Best Supplement For Cat Urinary Health – CystAid Plus

If you have a male cat prone to stress, CystAid Plus is a must!
CystAid Plus is a nutritional supplement that helps to manage lower urinary tract function and maintain a healthy bladder.
In other words, it reduces the chances of your kitty getting a UTI or bladder infection.
Urinary issues are common in male cats, as their urethra is much narrower than that of females, increasing the chance of blockage.
CystAid Plus contains N-acetyl D-glucosamine, which helps replace and maintain the bladder lining.
As urinary issues are often stress-induced, CystAid also contains L-Theanine, an amino acid (found in green tea) with natural calming properties.
CystAid Plus is easy to give your cat and has no strong smell or flavor. Simply sprinkle the capsule contents over your kitty’s food.
Best Cat Supplement For Skin And Coat – Coatex

Besides keeping them free from illness, we want to ensure our kitties have healthy skin and fur.
Coatex by VetPlus contains high levels of Omega 3 and Omega 6 EFAs, which have many benefits for your kitty’s coat, including:
- Reduces excess shedding
- Soothes irritated or dry skin due to parasites
- Reduces itching and flaking
- Promotes hair growth
- Makes fur softer and shiner
Coatex comes in liquid capsules. As the capsules are big, the best way to give this supplement is to cut it open and pour it over your cat’s food.
Final Thoughts On The Best Cat Supplements In Thailand
I’ve used all the supplements mentioned in this article on my own cats and kittens, and a qualified vet has highly recommended each one.
However, it’s important to remember that every cat is unique. I suggest consulting with your veterinarian before giving your cat any new supplement.
Additionally, while supplements can be beneficial, they should complement, not replace, prescription medication for any health issues your kitty might have. Always follow your vet’s advice on using supplements alongside prescribed treatments.
