What to watch with BDNF and Blutzucker?

BDNF (brain-derived neurotrophic factor) and blood sugar are linked via glucose metabolism and neuronal health. Elevated blood glucose (e.g., in insulin resistance or diabetes) tends to reduce BDNF levels, which may impair cognitive function. Conversely, exercise, intermittent fasting, and low-glycemic diets can increase BDNF. However, direct blood BDNF measurement is not standardized and fluctuates widely (time of day, stress). MyBody-X does not offer a BDNF test; blood glucose and HbA1c are well-established markers. Be cautious of marketing that promotes BDNF supplements as 'brain boosters' – evidence is mostly mechanistic or from animal studies. Maintaining stable blood sugar is a more evidence-based goal. If your glucose values are abnormal, consult a physician.
