MAIN TAKEAWAY:

Where LMNT Excels:
Due to the inclusion of additives and the chemical form of magnesium that LMNT’s recipe uses, it may have increased ability to dissolve in water. Furthermore, its plastic-coated stick pack design is not terrible for travel and taking a single serving on-the-go.
Where GRIT Excels:
GRIT’s glass packaging minimizes microplastic exposure and allows for a greater volume of electrolytes for a lower cost. This means more days fasting for less money.
By using only four simple ingredients, including magnesium chloride, you are only getting what your body needs with no extra filler or unknown chemicals messing with your fast. If you are having trouble dissolving GRIT, a shaker bottle works wonders.
LMNT packets can contain up to 450 mg of Maltodextrin.
Why does this matter?
Maltodextrin has been shown in studies to be higher on the glycemic index than corn syrup. This can create an insulin response in the body.
Higher insulin levels and lower insulin sensitivity are linked to:
⚠️ Obesity
⚠️ High Blood Sugar
⚠️ Hypertension (High Blood Pressure)
⚠️ Type 2 Diabetes
⚠️ Heart Disease
