DOES IT WORK?
Salt (sodium chloride) in supplements serves as a flavoring agent, stabilizer, or electrolyte source. Sodium is an essential electrolyte, but most people get way more than enough from their diet. The tiny amount in a supplement (10-200mg) is nutritionally insignificant compared to dietary intake of 3000-4000mg/day. Only useful in electrolyte-specific products.
