Only Essential Choline combines both choline and citrate. This is important because citrate activates choline as it energizes and alkalizes the cell. Essential Choline replenishes choline stores quickly and effectively, improving endurance and performance. Alkaline for Life Essential Choline comes in a liquid form to guarantee optimum absorption and purity. The commonly used form of choline, choline bitartrate, contains cornstarch and may contain reactive or irritative antigens. Our Essential Choline is contaminant free, more bioavailable than tablets or capsules, and more convenient!
