Will LMNT break my fast?Updated 14 days ago

No, LMNT will not break your fast. Calories break a fast by increasing blood sugar and provoking an insulin response — but the significance of that insulin response depends on how many calories you consume and what they came from.

LMNT contains so few calories that many folks in our community (who wear continuous glucose monitors, or CGMs) have shared that they don't experience any blood sugar increase when drinking LMNT. Since health is highly individual, we encourage you to test that yourself. If you prefer to avoid all calories during a fast, our Raw Unflavored drink mix contains zero calories — it's just sodium, potassium, and magnesium.
