While simple sugars from soda can cause a blood sugar spike in just 15 to 30 minutes, the complete metabolic journey of how long does sugar stay as energy is far more complex. The body's intricate system first uses glucose for immediate fuel, then stores it as glycogen, and ultimately converts any excess into long-term fat reserves. This timeline varies significantly based on factors like the type of sugar consumed, a person's activity level, and overall metabolic health.

According to several medical sources, most people experience an initial energy boost from B12 injections within 24 to 72 hours, especially if they have a deficiency. These injections bypass the digestive system for rapid absorption, providing a quicker effect than oral supplements.
