Can LCT help with stress?

The question of whether LCT (lactase persistence gene) can help with stress lacks scientific support in the provided context. LCT is only discussed regarding lactose digestion, not stress regulation. No studies in the given materials link LCT variants to stress resilience or mental well-being. Any potential connection via the gut-brain axis remains speculative and unsubstantiated. Direct-to-consumer genetic tests for LCT are not validated for stress management. Consumers should not rely on such tests for stress relief; evidence-based approaches like exercise, sleep hygiene, and counseling are more appropriate.
