Best MSM For Cats: Buying Guide & Our Top Picks (Review 2020)

a white cat

As your cat ages, they are more susceptible to significant issues with pain, inflammation, joint problems, fatigue, coat issues, and general impairments of everyday functions. 

Pets must have adequate MSM in their body to function optimally. Unfortunately, most pets struggle to get access to adequate sulfur. This is largely due to modern farming and pet food production methods, which has decreased the amount of sulfur found naturally in food sources, leaving most animals in a significantly deficient state. 

Even if your cat is getting adequate sulfur, they can greatly benefit from the addition of MSM that can quickly help with joint and pain issues, and promote optimal overall health, wellness, and coat appearance.

Whether your cat is deficient in sulfur or is getting adequate sulfur in their diet, we’ve got it covered in our Buying Guide and our top 5 picks of Best MSM For Cats out there.

In a hurry? Click here to jump straight to the reviews!


What is MSM?

MSM (Methylsulfonylmethane) is a naturally occurring sulfur compound that’s used to improve immune function, reduce inflammation and help regenerate healthy body tissue. 

The reason MSM contains so many benefits is that it provides biologically active sulfur, which is the third most abundant mineral in the body and required to support multiple structure and function within the body, such as connective tissues and the respiratory system. 

MSM can be found is small quantities in fruits, vegetables, grains, milk, and meat. The compound itself is actually created naturally through the earth's sulfur cycle when phytoplankton and algae die and decompose. It then releases sulfur compounds into the atmosphere where they are transformed to DMS.

DMS is then converted to DMSO in the presence of ozone and sunlight. From there, they return to the earth's surface in rain water and is absorbed by plant life and ultimately eaten by animals. 

The commercially available MSM products are manufactured because the amounts found naturally are too small for extraction. MSM is produced when DMSO (dimethylsulfoxide) is oxidized. Then, it gets purified by either through crystallization or distillation method to remove impurities.


What does Sulfur do For Your Cat?

As cats get older, the concentration of sulfur in the body begins to decline. As a result, your cat may develop dull fur, skin problems, joint pain, brittle nails, poor gastrointestinal system, and generally weak immune system.

Other signs of sulfur deficiency:

  • Fatigue and lack of energy
  • Joint pain and inflammation
  • Shoulder and neck pain
  • Hip and leg pain

Although sulfur is present in all cells of the body, with the highest concentrations found in joints, hair, skin, and nails. However, the therapeutic benefits occur at levels much greater than what’s found in a regular diet.

One of the main reasons you want to get MSM supplement for your cat is because it works in conjunction with glutathione to help detoxify the body. When your cat's body is deficient of sulfur, the detoxifying process is hindered. As you can imagine, this leaves your furry friend susceptible to a lot of health problems.

Additionally, sulfur is actually not stored in the body but rather used and the excess amount is flushed out daily. For cats, especially senior cats, this can be a problem if they are not getting enough in their diet. 

Sulfur also plays in a different critical roles in the health of skin, bones, cartilage, and fur. More benefits include the following:

  • Promotes energy 
  • Enhances overall mobility
  • Reduces pain and inflammation
  • Potent detoxification for your cats's entire body
  • Maintenance of healthy skin and hair
  • Relief of some allergy symptoms
  • Helps remove parasites from the digestive tract
  • Promotes general wellness

Is MSM Safe For cats?

MSM is considered to be very safe. It has been used for decades for both humans and pets. However, at the beginning, your cat may experience some detoxification symptoms such as vomiting and diarrhea.

Don’t fret, these symptoms will disappear as your cat's body acclimatizes and stabilizes itself. It is advisable to administer MSM supplement to your cat with food to help decrease gastrointestinal upsets.

If your pet is on medications, make sure your vet knows about MSM so they can confirm the ability to integrate MSM into your cat's overall care and health management protocol.

Buying guide: What to look out for when purchasing a MSM product

1. Price

The price of MSM supplements can vary greatly from one brand to another. If a product is overly priced, it doesn't absolutely mean it's a great product. It's also true if something is cheap it doesn't mean it's a low quality product.

Price alone doesn't guarantee the quality of a product. You also need to do your own research and compare products side by side to determine the best supplement for your cat.

2. Budget

Make sure to compare prices from different shops or online shops so that you get the lowest price for that particular supplement. You need to have your budget on check so that you only buy what you can afford. If you find that the product is either too expensive or too cheap, then look at the quality and other factors to find the best.

3. Flavor

It's also important to consider the flavor of a supplement, especially if your cat is a picky eater. It doesn't matter how great a product is if your the taste of the supplement is not appealing to your cat. Some MSM supplements are flavored with chicken or beef while other are not. Make sure you read the label carefully and choose the flavor your cat likes.

4. Different forms of MSM Supplement

Feline MSM supplements are available in liquid, powder, crystal, tablet and chew forms. Every cat has different preference, so learning what your cat likes and choosing supplements based on that knowledge can be very helpful.

Liquids - The liquid form is often more preferred as the ingredients are easily and quickly absorbed by your cat's body. It's also easier to mix the liquid with your cat's favorite food. 

Powders or crystals - Powers and crystals can easily be dissolved or mixed with your cat's favorite food.

Tablets - It can be a challenge to get your cat to swallow tablets. Additionally, the process of making tablets can have added binders and fillers which can significantly impact the amount of ingredients absorbed by your cat's body. If you buy  tablets, you can wrap the tablet with your cat's favorite food to hide it, making it easy for them to swallow. 

Chews - Chews are also easy to administer to your cat. Many companies have their chews flavored that your cat will like.

5. Know What You Are Looking For

Don't be enticed by advertisements that are very strategically done to promote their product. Make sure you know what you are looking for so you don't end up with a poor quality product that could potentially do more harm than good. 

Some companies may add words like "organic" "all natural" to entice you into buying it thinking that it is a great product for your cat. Make sure to  read ingredients and labels carefully. Additionally, do not hesitate to research well on the company that you will purchase supplements from.

6. Other Reviews

You may also want to check out how many other cat owners have purchased the supplement you are looking to buy. Inquiring your friends and relatives on the best products there are is another way to get reviews.

6 Comments on “Best MSM For Cats: Buying Guide & Our Top Picks (Review 2020)”

  1. Lovely article. I had no idea what MSM was until I read your article. The last cat I had was about 40 years ago. He was a tough cat. We lived in open fields so I thought of not fixing him so that he could defend himself. He did get in a lot of fights. He would come home with wounds of large bites. He was a big cat too. He came home every night for 7 years but on the night he didn’t return I knew that something got him. We lived in an area that had lots of coyotes. Thanks for writing this article. It brought memofries from the life of my cat.

    1. Hello Courtney,

      Thank you for sharing your story. Your story reminded me of my cat that also didn’t return and I am not sure what exactly happened to her. I still miss her to this day.
