PharmaGuideFeatures
The supplement and medication co-pilot you actually need.
Most apps check one bottle at a time. PharmaGuide reads your full stack as a system — flagging interactions, depletions, dose accumulation, recalls, and quality issues across every supplement and medication you take.
- 01Medication Depletion
Your medication may be depleting nutrients. We catch it.
Maps supported prescriptions to the vitamins and minerals they may draw down over time.
- 02Stack Intelligence
Your full stack. Checked as a system.
Multi-way interactions, cross-product dose summation, timing conflicts — your stack analyzed together.
- 03Ingredient & Quality
Active and inactive ingredients. Including the ones most apps skip.
Active and inactive ingredients parsed, proprietary blends decomposed, 4-pillar PG Score per product.
- 04Personal Fit
What's safe for one person may not be for another.
Profile-gated warnings tuned to your conditions, medications, and goals — irrelevant alerts stay hidden.
- 05Nutrient Accumulation
When 'more' becomes too much.
Tracks every nutrient across your full stack against RDA and Tolerable Upper Intake Level.
- 06Recall & Safety
When the FDA pulls something, you find out.
FDA recall monitoring and adverse-event signal awareness on the products you actually scanned.
Your medication may be depleting nutrients. We catch it.
Some common prescriptions are associated with lower levels of specific vitamins and minerals over months and years — for example, metformin and B12, or PPIs and magnesium absorption. We map supported medications to the nutrients they may deplete, and surface what to consider discussing with your clinician.
- Add a medication → see which nutrients may be affected
- Evidence-graded depletion mappings from published research
- Replenishment suggestions you can discuss with your clinician
- Updated as new pharmacology research is published
In practice
- Statin (atorvastatin, simvastatin)CoQ10 — supplementation discussed in cardiology guidelines
- MetforminVitamin B12 + Folate — depletion well-documented over long-term use
- PPI (omeprazole, pantoprazole)Magnesium, Vitamin B12, Calcium absorption reduced
- Loop diuretic (furosemide)Potassium, Magnesium, Thiamine lost in urine
- Combined oral contraceptiveB-complex + Folate + Magnesium routinely depleted

Your full stack. Checked as a system.
Most apps check one bottle at a time. PharmaGuide reads your stack as a system — multi-way interactions, dose overlap across products, and the timing conflicts that don't show up in any single label. The result is a Stack Health verdict you can act on.
- Multi-way analysis — interactions between any pair AND beyond
- Cross-product dose summation — three caffeine products at 80 mg each won't slip past 200 mg/day
- Stack Health verdict: Optimized · Solid · Decent · Needs review · Unsafe
- Timing conflicts surfaced (e.g. calcium ↔ levothyroxine 4-hour separation)
In practice
- Magnesium AM + Magnesium PM + Multi w/ magnesiumTriple-counted — combined dose flagged against tolerable upper intake
- Pre-workout + green tea extract + dark chocolate squares~340 mg caffeine — 70% above 200 mg/day general guidance
- Iron supplement + calcium-rich multi + thyroid medication3-way timing conflict — separate iron and calcium from thyroid by 4 hours

Active and inactive ingredients. Including the ones most apps skip.
We parse the active ingredients AND the inactive ones — fillers, binders, allergens, and the proprietary blends most apps skip because the math is hard. Every product gets a 4-pillar PG Score so you can compare brands on substance, not packaging.
- Active and inactive ingredients parsed — fillers, allergens, excipients
- Proprietary-blend dose decomposition — most apps can't read these; we can
- Probiotic strain + CFU and prebiotic fiber checks — strains named, live counts and fiber type verified, not just 'blend'
- PG Score across 4 pillars: ingredient quality, safety & purity, evidence, brand trust
- Third-party testing flags (USP, NSF, Informed Sport) where verifiable
In practice
- "Energy Blend 850mg" with no per-ingredient doseDecomposed — we estimate per-ingredient ranges and flag what's hidden
- "50 billion CFU probiotic" with strains unnamedStrain-gap flag — CFU counts mean little without the specific strains the evidence is built on
- Capsule with magnesium stearate + titanium dioxideInactive-ingredient flag — relevant for some autoimmune conditions
- Two melatonin brands, same dosePG Score divergence — third-party tested vs. unverified, evidence weight differs

What's safe for one person may not be for another.
Your conditions, age, current medications, and goals reshape every recommendation. Pregnancy. Hypertension. Anticoagulant therapy. Each modifies the safety calculus. We profile-gate every interaction so you only see warnings that actually apply to you.
- Profile gating — irrelevant warnings stay hidden, relevant ones surface clearly
- Medication ↔ condition flags — surfaces when something in your stack is risky given a diagnosis you've entered
- Pregnancy + breastfeeding flags treated as separate, never combined
- Drug-class awareness: SSRIs, statins, anticoagulants, hypoglycemics, more
- Goal-driven stack recommendations (sleep, energy, recovery, longevity)
In practice
- St. John's Wort + sertraline + 'mood support' goalAvoid — serotonin syndrome risk; review with a clinician
- Potassium + ACE inhibitor + 'kidney disease' profileFlag — combined hyperkalemia risk; surfaced because all three are in your profile
- High-dose vitamin A + 'pregnancy' profile flagCaution — high-dose preformed vitamin A may not be appropriate; review before use
- Niacin + active statin therapyMonitor — interaction with certain hypoglycemic profiles

When 'more' becomes too much.
Fat-soluble vitamins accumulate. Mineral overdoses are real. We track nutrients across your stack against the **Recommended Daily Allowance (RDA)** and the **Tolerable Upper Intake Level (UL)** — and flag when your intake crosses into the zone where supplementation may do more harm than good.
- RDA + UL tracking per nutrient across the entire stack
- Fat-soluble accumulation flags (vitamin A, D, E, K)
- Mineral excess detection (iron, zinc, selenium)
- Visualized as a per-nutrient meter so you see the headroom
In practice
- Multi + dedicated vitamin D + cod liver oil~6,000 IU vitamin D/day — approaching adult UL of 4,000 IU
- Multi + zinc lozenges + zinc-forward immune blend~70 mg zinc — above 40 mg UL; chronic excess depletes copper
- Iron supplement + iron-fortified multi~80 mg iron — past UL of 45 mg; oxidative stress risk

When the FDA pulls something, you find out.
The FDA recalls dietary supplements regularly — adulterated formulations, undeclared pharmaceuticals, contamination, mislabeling. Most users never hear about it. PharmaGuide monitors active recalls and FDA Adverse Event Reporting System (FAERS) signals so a product in your stack doesn't quietly become unsafe without you noticing.
- FDA recall monitoring across dietary supplements and medications
- FAERS-linked safety signals — adverse event reports surfaced in-app
- Lot-level recall checking when manufacturers publish lot data
- FDA warning letter awareness for flagged brands
In practice
- Brand X recalled for undeclared sildenafilStack alert — flagged immediately if you've scanned that product
- Manufacturing recall by lot number 2026-AC-0814Lot match — your bottle's lot triggers the warning, others don't
- FAERS adverse event cluster on a kratom productPotential safety signal — surfaced for review with appropriate context
