Some common ingredients found in Fast Start Keto Gummies include exogenous ketones, MCT oil, and electrolytes. Exogenous ketones are supplemental ketones that can help promote ketosis and increase energy levels. MCT oil, which is derived from coconut oil, is a type of healthy fat that can help increase ketone levels in the body. Electrolytes, such as sodium, potassium, and magnesium, are important for maintaining hydration and electrolyte balance, which can be challenging on a keto diet.
