Traffic: forms and doses, not the vitamin's name alone
Searches for a vitamin by name alone go to encyclopedias and pharmacies. The demand a brand can win is one step more specific: vitamin D3 5000 IU, methylcobalamin B12 drops, magnesium glycinate 400 mg, chewable vitamin C for kids, iron without constipation. Each of those is a page, and the page has to explain why that form, at that dose, in that format. Comparison content sits beside it, because glycinate versus citrate and D3 versus D2 are searched constantly and answered badly. The traffic lever is building the form and dose layer as indexable collections and the comparison layer as guide pages that link to them.
