Anxiety, Bloated, Tired, Tachycardia
Posted by Sharada (Los Angeles) on 09/07/2025

Last week, I just started using 1000 mg capsules 1x in the evenings. For the first time in years I experienced tachycardia a few days in. Being an experienced meditator, I was able to do some breathwork to calm down. I thought it was a strange bout of anxiety. In addition, I have been bloated and feeling unusually tired and also mentally foggy. After reading all these comments, I've decided to take a pause from MSM. My joint pain seems to have improved but I am not liking feeling this tired and bloated.
