Evidence check: Fitness Vitality DNA in the context of fertility

The MyBody-X DNA Nutrition Test may include some genes related to lipid metabolism, such as APOE, but effect sizes are small. The results are not diagnostic and do not replace a blood test. LDL and HDL levels are primarily influenced by lifestyle, diet, and exercise. Evidence for direct cholesterol insights from such genetic tests is weak and based on marketing claims. A clinical lipid panel is required for reliable assessment. Caveat: genetic variants explain only a small fraction of cholesterol variance.
