Evaluates dietary nutrition gaps and supplement safety by coordinating nutrition analysis, food alternatives, supplement interaction checks, adverse event screening, and effect tracking. Use when the user wants to optimize their supplement stack or check supplement safety.
Scenario orchestration skill for evaluating dietary nutrition gaps and optimizing supplement regimens. Coordinates nutrition analysis, food alternative queries, supplement-supplement and supplement-drug interaction checks, adverse event screening, genetic personalization (optional), and effect tracking. Targets users who want a complete assess-identify-optimize-track pipeline for their supplement stack.
This skill does not perform analysis directly. It orchestrates multiple sub-skills in sequence.
This skill is for nutritional management reference only and does not constitute medical diagnosis or treatment advice.

nutrition-analyzer. Analyze current dietary intake of each nutrient. Compare against RDA (Recommended Dietary Allowance) to assess achievement. Identify nutrients that are adequate vs deficient. Evaluate macronutrient ratios (carbohydrate/protein/fat).food-database-query. For each deficient nutrient, query foods rich in that nutrient. Provide "food-first" recommendations (e.g., "Calcium deficit -- 250ml milk + 100g tofu daily provides ~500mg calcium"). Compare feasibility of food supplementation vs pill supplementation.tooluniverse-drug-drug-interaction. Check supplement-supplement interactions (e.g., calcium and iron compete for absorption; vitamin D and calcium are synergistic; vitamin C enhances iron absorption). Check supplement-drug interactions (e.g., iron/calcium impair levothyroxine absorption; vitamin K antagonizes warfarin). Flag combinations that must be taken at separate times. Flag contraindicated combinations.tooluniverse-adverse-event-detection. Retrieve known adverse event signals for each supplement. Assess risk level at current dosage. Flag high-dose risks (e.g., vitamin A hepatotoxicity, excess iron GI effects, high-dose zinc causing copper deficiency). Evaluate long-term use risks.nutrigx_advisor (requires genetic testing data). Assess MTHFR variant (methylfolate vs standard folic acid). Assess VDR gene (individual vitamin D requirements). Assess FADS1/FADS2 (omega-3 conversion efficiency). Assess HFE (iron metabolism abnormality risk). Assess COMT/CYP (caffeine/supplement metabolism variation).health-trend-analyzer. Analyze fish oil use vs lipid panel trends. Analyze vitamin D supplementation vs 25(OH)D level changes. Analyze iron supplementation vs hemoglobin/ferritin changes. Analyze melatonin use vs sleep quality improvement. Correlate supplement duration with observed effects.goal-analyzer. Track supplement adherence (daily compliance). Evaluate health goal progress (bone density improvement, fatigue relief, etc.). Set 30-day re-evaluation timepoint.health-memory. Write supplement plan and assessment results to memory/health/daily/{YYYY-MM-DD}.md. Update memory/health/items/supplements.md (supplement list and change history). Update other relevant item files.The user provides the following in natural language:
Current supplements:
- Vitamin D3 2000 IU daily after breakfast

# Supplement Optimization Report -- YYYY-MM-DD
## 1. Current Supplement Assessment
| Supplement | Dose | Verdict | Rationale |
|-----------|------|---------|-----------|
| Vitamin D3 | 2000 IU/day | Necessary | Dietary vitamin D insufficient; bone density is a health goal |
| Fish oil | 1000mg/day | Optional | Dietary fish intake is moderate; could replace with 3x/week fish |
| Calcium | 600mg/day | Necessary | Dietary calcium ~500mg/day; supplement brings total to ~1100mg, near RDA |
| Iron | 60mg/day | Needs recheck | Dose is high; check ferritin to confirm ongoing need |
| B-complex | Standard dose | Redundant | Dietary B-vitamins already meet RDA; no clear deficiency |
Verdict categories:
- **Necessary**: Diet cannot meet need + clear health requirement
- **Optional**: Diet mostly sufficient; supplement provides extra assurance
- **Redundant**: Diet already adequate; supplement adds no benefit
- **Needs recheck**: Lab test needed to confirm whether to continue
- **Risk**: Current plan has safety concerns
## 2. Interaction Warnings
### Supplement x Supplement
| Combination | Type | Notes |
|-------------|------|-------|
| Calcium + Iron | Absorption competition | Calcium inhibits iron absorption by 40-50%; must take separately (>= 2h apart) |
| Vitamin D + Calcium | Synergistic | Vitamin D enhances calcium absorption; take together |
| Vitamin C + Iron | Synergistic | Vitamin C enhances non-heme iron absorption; consider pairing |
### Supplement x Medication
| Combination | Type | Notes |
|-------------|------|-------|
| Iron + Levothyroxine | Absorption interference | Iron severely impairs thyroid hormone absorption; separate by >= 4 hours |
| Calcium + Levothyroxine | Absorption interference | Calcium impairs thyroid hormone absorption; separate by >= 4 hours |
## 3. Optimized Dosing Schedule
| Supplement | Recommended Time | With food? | Notes |
|-----------|-----------------|------------|-------|
| Levothyroxine | 06:30 | Empty stomach | Take first; separate from all supplements by 4h |
| Iron | 10:30 | Empty stomach | 4h after levothyroxine; best absorbed on empty stomach |
| Vitamin D3 + Calcium | 12:00 (lunch) | With meal | Fat-soluble vitamin D needs dietary fat; calcium is synergistic |
| Fish oil | 12:00 (lunch) | With meal | Fat-soluble; better absorbed with food |
| B-complex | (recommend discontinuing) | -- | Dietary intake already sufficient |
## 4. Food-First Alternatives
| Nutrient | Current Gap | Food Alternative | Can fully replace supplement? |
|----------|------------|-----------------|------------------------------|
| Calcium | ~500mg/day | 250ml milk (300mg) + 100g firm tofu (200mg) daily | Yes, if consistently maintained |
| Iron | Needs lab check | Liver or beef 2-3x/week + pair with vitamin C source | If ferritin is normal, food can replace |
| Vitamin D | Very hard to meet via diet | Salmon/mushrooms + 15 min daily sun exposure | Difficult to fully replace; continue supplement |
| Omega-3 | Slightly low | Deep-sea fish 3x/week (salmon/mackerel/sardines) | Can replace fish oil supplement |
## 5. Dosage Recommendations
| Supplement | Current | RDA | UL | Recommended | Notes |
|-----------|---------|-----|-----|-------------|-------|
| Vitamin D3 | 2000 IU | 600 IU | 4000 IU | 2000 IU (maintain) | Safe range; supports bone density goal |
| Calcium | 600mg | 1000mg | 2500mg | 600mg (reduce to 300mg if food intake improves) | Diet + supplement total should not exceed 1500mg |
| Iron | 60mg | 18mg (F) / 8mg (M) | 45mg | Check ferritin first | Current dose exceeds UL; not recommended for non-anemic individuals |
| Fish oil | 1000mg | No RDA | 3000mg EPA+DHA | Discontinue if food intake is sufficient | Safe range |
## 6. Genetic Personalization
(Requires genetic testing data. If available, the following analysis will be shown:)
- **MTHFR**: C677T/A1298C variant status -- determines folate form (methylfolate vs standard folic acid)
- **VDR**: Vitamin D receptor gene variant -- adjusts vitamin D dosage
- **FADS1/FADS2**: Omega-3 conversion efficiency -- determines need for preformed EPA/DHA
- **HFE**: Iron metabolism gene -- iron supplementation safety assessment
## 7. 30-Day Tracking Plan
| Timepoint | Action |
|-----------|--------|
| Day 1 | Adjust dosing schedule per new plan |
| Week 1 | Monitor for GI discomfort or other reactions |
| Week 2 | Assess adherence + subjective improvement (fatigue relief?) |
| Week 4 | Re-evaluate: ferritin check, adherence stats, goal progress |
| Week 8 (optional) | Check 25(OH)D level, lipid panel |
### Recommended Follow-Up Labs
- Ferritin + serum iron + TIBC (confirm whether iron is still needed)
- 25(OH)D (confirm vitamin D adequacy; target 30-50 ng/mL)
- Bone density (recheck in 6-12 months)
| Severity | Condition | Action |
|---|---|---|
| High | Contraindicated supplement-drug combination (e.g., vitamin K + warfarin) | Discontinue the supplement immediately; contact physician |
| High | Supplement dose exceeds UL | Recommend dose reduction or discontinuation; warn of overdose risk |
| Medium | Competing supplements not taken separately | Adjust dosing schedule |
| Medium | Suspected adverse reaction reported | Recommend stopping the suspected supplement and observing |
| Low | Redundant supplement (dietary intake already sufficient) | Suggest evaluating whether to continue |
