Which immediate side effects often manifest in the gastrointestinal tract after consuming too much kelp?

Gas and bloating, diarrhea, and general stomach upset.

Beyond the systemic concerns related to mineral balance, immediate negative reactions to overconsuming kelp often involve the digestive system. Many consumers report mild to moderate disturbances following ingestion. The common complaints specifically cited include the development of gas and bloating, episodes of diarrhea, and general sensations of stomach upset. These gastrointestinal disturbances are generally attributed to the high fiber content characteristic of sea vegetables and the unique composition which some digestive systems struggle to process initially. While usually transient, these effects can significantly impact daily life.
