Practical D3 Decision Framework#

1) Deficiency context first#

Use labs and physician context where possible before prolonged high-dose use.

2) Dose strategy matters#

Daily, weekly, and high-IU formats are not interchangeable without context.

3) Label quality matters#

Prefer products with clear IU disclosure, serving size, and quality transparency.

Data Gaps You Should Know#

• D3 subgroup is currently thin (3 strongly identifiable D3 products), limiting broad rank confidence.
• DB lacks a standardized micronutrient taxonomy field (e.g., primary_nutrient = Vitamin D3) for better retrieval.
• No serum-marker integration fields (e.g., baseline/target 25(OH)D context), so this remains educational, not personalized.

Recommended DB Additions#

• primary_nutrient (enum/text) on products
• nutrient_amount_per_serving + unit normalization
• maintenance_vs_correction_dose_band (tag)
