Mineral Absorption Calculator
Estimate how much of a mineral your body actually absorbs. Adjust dosage, mineral type, form bioavailability, and meal factors to see real absorbed amount.
Step 1: Mineral & Dosage
Base absorption varies
Calcium ~30%, iron ~15% (heme iron higher), magnesium ~45%, zinc ~25%. These are typical supplement averages. Custom allows for specific compounds.
Step 2: Absorption Factors

Understanding factors
Form: citrate (higher) vs oxide (lower). Meal: food can inhibit (phytates) or enhance (vitamin C). Metabolic: age, gut health, etc.

Absorption formula
Absorbed (mg) = Dosage × (Base%/100) × (Form/100) × (Meal/100) × (Metabolic/100)
All factors are percentages. Example: 500 mg × 0.45 × 1.0 × 1.0 × 1.0 = 225 mg absorbed.
