Micronutrient Opt. Calculator Description
What Are Micronutrients?
Micronutrients are essential dietary components required in small amounts. They support:
- Enzymatic reactions and metabolic cycles
- Hormonal production and signaling
- Genetic expression and repair
- Neurological performance
- Immune modulation
Micronutrient Categories
- Fat-soluble vitamins: A, D, E, K
- Water-soluble vitamins: B-complex, C
- Major minerals: Calcium, magnesium, sodium, potassium
- Trace elements: Iron, zinc, selenium, iodine, copper
Why Optimize Micronutrient Intake?
Even mild deficiencies can hinder physical and cognitive performance. Optimization benefits include:
- Energy Metabolism: Enhanced mitochondrial function
- Brain Function: Stable neurotransmitter production
- Bone & Skin Health: Strengthened structural integrity
- Detoxification: Antioxidant defense via glutathione, SOD
Pro Tip: Food labels show total nutrient content—not what's actually absorbed. For example, plant-based iron may be only 10% bioavailable.
How We Quantify Intake: NDI & EAD
Micronutrient Density Index (NDI)
NDI expresses how well your intake meets biological needs:
NDI (%) = [(Intake / RDI) × Bioavailability Factor] × 100
Effective Absorbed Dose (EAD)
EAD adjusts further for gut health, inhibitors, and retention:
EAD = Intake × Bioavailability × Retention Coefficient
Key Terms
- Intake: Amount consumed per day
- RDI: Recommended Daily Intake
- Bioavailability: % absorbed from food/supplement
- Retention Coefficient: Fraction retained after digestion and competition
Enhancers & Inhibitors of Absorption
Enhancers
- Vitamin C increases non-heme iron uptake
- Healthy gut microbiota promotes K2, biotin synthesis
- Magnesium supports vitamin D activation
Inhibitors
- Phytates reduce zinc, calcium, iron absorption
- High-dose calcium competes with magnesium and iron
- Antacids/PPIs decrease stomach acid and impair nutrient release
Edge Cases That Alter Nutrient Needs
Bariatric Surgery
- Reduced stomach acid and intrinsic factor → B12, iron, and fat-soluble vitamin deficiency risk
- Typical need: 200–300% of RDI
Endurance Athletes
- Increased sweat loss → sodium, magnesium depletion
- Elevated oxidative stress → higher B2 and B6 demand
Chronic Alcoholism
- Blocks thiamine and folate absorption
- Recommended: 200 mg/day thiamine + 1 mg folate
Vegan Diet
- Lower absorption of B12, iron, zinc
- Suggested forms: methylcobalamin, iron bisglycinate
Celiac Disease
- Gut lining damage → malabsorption of fat-soluble vitamins, iron, and folate
- Increase intake to 2–3× RDI
Mini Case Studies
Ultra-Endurance Vegan Runner (28F)
- Symptoms: Fatigue, low ferritin, high MCV
- Deficits: Iron, B12
- Protocol: 25 mg iron bisglycinate + 500 mg vitamin C, 1000 µg methylcobalamin daily
Senior Male with Osteopenia & CKD (67M)
- Findings: Vitamin D = 18 ng/mL, low-normal magnesium
- Protocol: 2000 IU vitamin D3, 600 mg calcium citrate, 400 mg magnesium glycinate
