MSM Supplement Side Effects

Methylsulfonylmethane (MSM) is a popular health supplement known for its ability to relieve arthritis and pain. However, like any supplement, MSM can cause mild to severe side effects. The amount you take, other medications you take, and your own personal constitution will affect how MSM works for you.

In this article, we will discuss some of the potential side effects of MSM and how to avoid them.

MSM Side Effects

1. Heart Issues

One of the most concerning side effects of MSM is its potential to affect the heart. Some people have reported experiencing heart palpitations, tightness in the chest, and increased blood pressure after taking MSM.

2. Emotional Side Effects

Emotional side effects caused by MSM can be equally as debilitating and frightening, including anxiety and mild to severe depression. Mood swings may also be more pronounced.

A number of Earth Clinic readers have reported a severe case of anxiety one to two days after starting MSM.

3. Skin Issues

MSM can also affect the skin with rashes, dry skin, hives, and itching.

4. Digestive Issues

Digestive side effects can include gas, foul stools, constipation, diarrhea, and urine retention.

Additional Side Effects

Other commonly reported side effects of MSM include:

  • Headaches 
  • Migraines 
  • Insomnia 
  • Muscle Cramps 
  • Increased Thirst 
  • Dehydration 
  • Fatigue 
  • Exhaustion
  • Dizziness
  • Nausea
  • Vomiting
  • Allergic reactions (such as itching, swelling, or difficulty breathing)
  • Flushing
  • Excessive Sweating
  • Kidney Problems (in rare cases)

How to Avoid MSM Side Effects

To avoid these side effects, it is important to start slowly and increase your dosage gradually.

Check labels and use a quality brand recommended by someone you know or a natural health practitioner.

Take MSM early in the day and with food to minimize the risk of side effects.

It is also important to be aware that some individuals may be more susceptible to side effects from MSM, including those with a history of reactions to sulfa drugs, mood disorders, and nutritional deficiencies.

MSM: Is it for Everyone?

MSM may not be suitable for everyone, and certain groups of people may be at higher risk of experiencing side effects. If you have a history of reactions to sulfa drugs, you may also have trouble with MSM. People with mood disorders may also be more likely to experience serious psychological side effects such as anxiety and depression when taking MSM. Additionally, if you have mild to serious nutritional deficiencies, MSM could exacerbate the problem by depleting molybdenum, an essential trace mineral.

If you take prescription or over-the-counter medications regularly, MSM may affect the way your medications work. It is important to consult with a healthcare provider before taking MSM if you have any underlying health conditions or are taking any medications.

In conclusion, while MSM can provide many health benefits, it may not be suitable for everyone. It is important to be aware of the potential risks and consult with a healthcare provider before taking MSM if you have any concerns. If you experience any side effects or have any concerns about taking MSM, it is important to consult a healthcare provider.
