What role does BDNF play in Blutzucker?

BDNF (Brain-Derived Neurotrophic Factor) is a protein expressed in the brain and peripheral tissues such as muscle and adipose tissue. It plays a significant role in blood sugar regulation by enhancing insulin sensitivity, promoting glucose uptake into skeletal muscle, and supporting pancreatic beta-cell function. Observational studies have consistently linked low BDNF levels with insulin resistance, impaired glucose tolerance, and increased risk of type 2 diabetes. However, the evidence is primarily correlational; few randomized controlled trials confirm a direct causal effect. MyBody-X does not currently offer a specific BDNF test for blood sugar. Direct-to-consumer genetic tests that include BDNF variants should be interpreted cautiously, as their clinical utility for individual glucose management is not well established. A balanced diet and regular physical activity remain the most effective strategies for blood sugar control.
