Visualize How Insulin Works

See how the timing of your insulin bolus relative to meal start affects blood glucose. Learn about pre-bolusing and timing for different meal types.

Explore how splitting a bolus into two doses at different times can better match insulin action to the extended absorption of high-fat meals.

Understand how exercise lowers blood glucose and how the timing of food and insulin around workouts affects your response.

For insulin pump users: see how adjusting your basal rate before, during, and after exercise affects blood glucose management.

Plan for long workouts of 4+ hours. Model pre-exercise fueling, in-exercise nutrition, pump temp basals, and post-exercise recovery.

See how anaerobic effort — sprints, heavy lifts, intense intervals — raises blood sugar during the workout, then creates a delayed low risk hours later, the opposite of steady aerobic exercise.

Compare endogenous, inhaled, rapid-acting, and regular insulin covering the same meal. Same dose, very different peaks and durations — so each needs its own timing strategy.

Compare NPH, detemir, glargine, and degludec at a correct steady dose. See why NPH's peak can cause a low that flat long-acting insulins do not — they are not interchangeable.

Combine boluses, meals, exercise, and temp basals across a full day. See how decisions stack and compound — from morning dawn phenomenon to overnight sensitivity.
