Is “normal” blood sugar truly safe for your brain? 🧠 Research shows cognitive decline risk can begin as low as an HbA1c of 5.5%—a level often labeled “healthy.” Multiple studies in non-diabetic adults have found a linear increase in memory decline and brain aging as HbA1c climbs above 5.5%, years before reaching diabetic levels. That’s why aiming for optimal, not just normal, matters for lifelong brain health.
