Daily Recommended Dosage Needs: Based on Dietary Reference Intakes (DRIs) including RDA (Recommended Dietary Allowance), AI (Adequate Intake), and UL (Tolerable Upper Intake Level) for different age groups and genders.

Vitamin D Dosage Calculation: Adjusts based on sun exposure (low: 1000-2000 IU, moderate: 600-1000 IU, high: 400-600 IU), skin type, geographic location, and seasonal variations for optimal serum 25(OH)D levels (30-50 ng/mL).

Deficiency Risk Assessment: Analyzes symptoms, dietary patterns, lifestyle factors, and health conditions to calculate probability scores for specific vitamin deficiencies with medical accuracy.

Pregnancy Prenatal Requirements: Trimester-specific adjustments: Folate (600 mcg), Iron (27 mg), Vitamin D (600 IU), Iodine (220 mcg), Calcium (1000 mg) with enhanced absorption considerations.

AI Accuracy Enhancement: Our algorithms incorporate clinical research data across different populations, health conditions, and medication interactions to provide context-aware vitamin recommendations.
