Sodium Bicarbonate

60-90 minutes before exercise

Sodium bicarbonate, commonly known as baking soda, is an alkaline compound that has been used for decades as an ergogenic aid in sports performance. It works by increasing the blood's buffering capacity, allowing athletes to sustain higher intensities of exercise for longer periods. It is one of the most well-researched performance supplements, particularly for short-duration, high-intensity activities.
