If you take a daily medication,
your body may be depleted of
key nutrients you don't know about.

Most physicians don't discuss nutrient depletions. Most patients don't ask. This tool surfaces what the published research shows — for 50 common medications — in under 60 seconds.

Smoking depletes vitamin C (plasma levels run ~4× lower than non-smokers), vitamin E, folate, B6, and B12. Cadmium in smoke displaces zinc and lowers selenium bioavailability.

Do not take beta-carotene supplements if you smoke.

ATBC (29,133 smokers) and CARET (18,314 smokers) both showed 18–28% more lung cancers and higher all-cause mortality with beta-carotene supplementation. CARET was stopped early. Risk persisted after stopping. Get carotenoids from food.

Repletion targets
  • Vitamin C: 200–500 mg/day
  • B-complex with active folate, B6, B12
  • Vitamin D to 40–60 ng/mL 25(OH)D
  • Zinc 15–25 mg/day
  • Vitamin E and carotenoids from food only

Strongest intervention: cessation. Repletion mitigates; it does not neutralize.

Medications can interfere with how your body absorbs, uses, and retains nutrients.

This isn't obscure biochemistry. It's documented in peer-reviewed literature — and it matters more as you age, when baseline nutritional reserves decline and medication use typically increases.

CoQ10 (ubiquinol)
Metformin

Vitamin B12
Loop Diuretics
Documented consideration:

These are examples only. The full tool covers 50 medications. Results are educational, not diagnostic. Discuss with your clinician before making any changes.

Three steps. Under a minute.

1
Select your medication
Choose from 50 commonly prescribed medications across statins, antihypertensives, diabetes medications, antidepressants, and more.
2
See the nutrient considerations
Each result shows which nutrients may be affected, the mechanism of action, and the strength of evidence — graded A through D.
3
Review with your clinician
Results link to the source studies. Bring the output to your next appointment — this tool is designed to support that conversation, not replace it.

If you can't cite the trial, you can't make the claim.

Every entry in this tool is graded against the same standard applied to all EBL content: human trial data first, mechanistic data labeled as such, manufacturer claims excluded. The same methodology published publicly on our Methodology page.

"The longevity space floods patients with recommendations backed by nothing more than a cell study or a sales page. We apply one standard: what do human trials actually show, at the dose that was actually used?"
