Can taking MSM trigger heart palpitations?

Woman messaging her heart Reader says, I have been taking MSM since June. I love it and passed the product on to a friend of mine who had similar issues with arthritis in her hands. She stopped taking it because she experienced heart palpitations, migraines, and severe bloating. I can understand the headaches and bloating but I have never heard of heart palpitations from taking MSM.

This is what her doctor said:

Likely a bad reaction from immune cross-reaction. Most products are not auto-immune neutral.

Have you come across this issue and can you give me any advice about the problem?

My response

I am not a licensed physician or medical practitioner, so please don’t take my comments as medical advice. With that disclaimer aside, what I can tell you is that a heart palpitation is one of the known detox reactions that can result from taking MSM (aka organic sulfur). Such a response indicates that the body is trying to eliminate toxins at a faster rate than it can handle it.

I am an active distributor for the Cellular Matrix Study, which has been evaluating the health effects of the product for the past 16 years. The study has determined from user feedback that taking too little MSM is more likely to result in an adverse reaction than taking too much. The recommended dose for individuals weighing under 200 pounds is 1 measured teaspoon of MSM twice a day, as the body needs to be provided with a fresh supply of sulphur every 12 hours. Any excess MSM that the body cannot use will be safely excreted in the bowels. If your friend is only taking a quarter or half teaspoon of MSM once a day, that can lead to a detox reaction.

To resolve many detox reactions to MSM, I recommend these two steps:

1. IMMEDIATELY take another dose of MSM with food or dissolved in a glass of water. I know this sounds counterintuitive, but this is what is known to work in many cases. As the body adjusts to the daily detox process, the adverse symptoms should begin to disappear.

2. The other key component to a successful MSM protocol is maintaining a proper level of hydration. It’s the oxygen in the water we drink that gets transported to the cells and allows them to repair and regenerate themselves in a healthy manner. The water we drink also enables toxins to be flushed out of our bodies. If we are dehydrated, then toxins accumulate without being expelled, which can lead to the type of bodily response that you’re describing. The rule of thumb is to drink one ounce of water for every two pounds of body weight. For instance, if your friend weighs 128 pounds, then the daily amount of water she should drink would be about 64 ounces.

Regarding the subject of proper hydration, I refer all inquiries to Dr. F. Batmanghelidj’s book called “Your Body’s Many Cries for Water” that is widely available on Amazon ( and other outlets.

    I wanted to know the best msm brand. Im using kalas optimsm but i had read somewhere that if the msm does not take atleast a few minutes to disolve in room temp then its impure although mine just dissolves instantly.

    The advice left above is ridiculous. If you have heart palpitations as the result of at supplement, STOP using it. Listen to your body.
