Approximately 7-10% of the world's population suffers from sodium sensitivity. For those individuals, or those with fluid retention issues on the whole, additional sodium is generally not recommended, and our product is therefore not likely to be a good fit. However, approximately 90-93% of the world's population experiences no rise or only a modest, temporary increase in blood pressure. Those that try it tend to report the effects of higher-sodium electrolyte supplementation as "very positive," overall. If you have any medical conditions which necessitate the consumption of a low-sodium diet, using a high-dose electrolyte supplement is not recommended. If you experience adverse symptoms or effects such as nausea, bloating, stomach pains, diarrhea or vomiting when trying LMNT, cease use of the product. Note the quantity of water you use to dilute LMNT, the timeframe for drinking it (e.g. sipping it over the course of an hour vs. chugging it in a few mins), and any other new activities or dietary tinkering might have an impact on your experience of LMNT.
