What to watch with LCT and sleep?

The question about LCT (lactase persistence) and sleep is unusual because LCT primarily governs lactose digestion and has no direct established link to sleep. There is no strong human evidence connecting LCT variants to sleep quality or duration. Indirectly, lactose intolerance symptoms like bloating or discomfort might disturb sleep, but this is individual and not genetically predictive. MyBody-X tests for LCT are designed for lactose tolerance, not sleep. For sleep issues, focus on proven factors like melatonin, stress, and sleep hygiene. The evidence for an LCT-sleep connection is weak; be cautious of marketing claims that overstate such links.
