Is Fitness Vitality DNA useful for fertility?

The usefulness of a 'Fitness Vitality DNA' test for fertility is questionable. These direct-to-consumer tests typically analyze SNPs related to metabolism, exercise response, or nutrient processing—not fertility. Fertility is a complex trait influenced by hormonal balance, age, lifestyle, environmental factors, and medical conditions. Some tested genes (e.g., ADRB3, GPX1) have weak mechanistic links to oxidative stress or energy metabolism, but no clinically validated relevance for conception. Evidence for such tests in fertility is largely marketing-driven; no controlled studies demonstrate benefit. A DNA test cannot replace medical fertility workup (hormone panels, ultrasound, semen analysis). Consumers should not rely on SNP-based 'fitness' tests for fertility decisions. Safety note: Do not change supplements or lifestyle based solely on these results without consulting a specialist.
