No image communicates why K2 matters (directs calcium to bones, not arteries). Without this story, price-sensitive buyers choose cheaper plain D3.", "fix": "Add infographic: 'D3 + K2 — the essential combination. D3 raises your vitamin D levels. K2 (MK-7) directs calcium to your bones, not your arteries. Together, they work.'" },

Nothing in current imagery communicates 'as recommended by healthcare professionals'. Competitor Vitabiotics leads with clinical credibility badges.", "fix": "Add 'Recommended by healthcare professionals' badge or lifestyle image of consultation context. Alternatively, a review quote overlay: '\"My rheumatologist recommended this\" — Feefo 5-star review'." },

Ask your GP to test at your next appointment.'" },
