Looking for a way to change up your usual pre-workout supplement? Try a Beet Root Powder Pre-workout Smoothie! Beet root powder can provide several health benefits. It contains betaine, which helps provide important support for a healthy cardiovascular system and liver health. It also works with B-vitamins to support normal homocysteine levels. To help reduce any bitter taste, mix it with a sweeter fruit such as pineapple to balance the flavors and create a delicious smoothie that makes a great pre-workout drink.
