Propel is an excellent "middle ground" hydration supplement. It’s more flavorful than plain water but much healthier than soda or full-sugar Gatorade. It’s an affordable, zero-calorie way to ensure you’re hitting your daily water intake while getting a small boost of vitamins.The grape flavor is prominent and hits that nostalgic "purple drink" profile without being overly medicinal. Because it is sweetened with acesulfame potassium and sucralose, it has a very crisp, sweet taste. If you aren't a fan of artificial sweeteners, you might notice a slight aftertaste, but for most, it’s refreshing and light.
