When is fast-acting glucose taken?

When is fast-acting glucose taken?

• A. Immediately after meal
• B. 15 minutes before meal
• C. 2 hours before meal
• D. 30 minutes before meal

Answer: (B)

Fast-acting glucose should be timed so its quick rise in blood sugar overlaps with the period when insulin is active during a meal. Taking it about 15 minutes before a meal lets the glucose start to enter the bloodstream as you begin eating, so the peak glucose availability lines up with the meal’s glucose absorption. This helps prevent lows during the post-meal period and supports better overall control as the meal is digested. If you wait until after the meal, the rapid rise may come too late to prevent post-meal lows or spikes, and taking it much earlier than 15 minutes before can cause the glucose to peak well before you eat, which is less effective for matching the meal.
