What it is & primary uses

02

Main benefits

  • A small proof-of-concept ALS trial reported a signal when TUDCA was added to standard treatment.
  • That disease-specific result does not establish liver protection, longevity benefit or a routine supplement dose for healthy users.
03

Studied protocols

Research doses are grouped by outcome. They describe study designs—not a personal prescription.

Cholestatic-disease research

2 g/day in a small ALS adjunct trial; no general wellness dose

Very low confidence
Study duration
Commonly 4–12 weeks; protocol and outcome vary
Interpretation
That disease-specific result does not establish liver protection, longevity benefit or a routine supplement dose for healthy users.

Clinical or experimental context—professional guidance is especially appropriate.

04Food sources & equivalents
Food sources & equivalents

Can food provide a studied amount?

No direct food equivalent
Comparison target2 g/day in a small ALS adjunct trial; no general wellness dose

TUDCA in this supplemental form does not have a reliable one-to-one food equivalent.

No direct food equivalent for supplemental TUDCAFood amount varies

Dietary exposure; verify composition before comparing with a studied supplement dose

How this was estimated
Dose Radar compares the declared active ingredient with official composition data or the studied standardized extract—not with marketing names.
Important limitation
Natural content, preparation, bioavailability and formulation vary. This comparison does not prove equal physiological effect.

Food equivalents compare ingredient mass using published composition values. They do not prove equal absorption, formulation, physiological effect, safety or personal need.

05How to take it for absorption & tolerance
Meal relationship

With food

Evidence-informed
With food; formulation and tolerance remain part of the comparison.

Food commonly improves gastrointestinal tolerance, although it can change absorption for some ingredients.

Practical approach
Divided clinical dosing in the cited trial. Keep the formulation and daily total consistent with the evidence context shown above.
Watch for
Bile-acid medicines

Meal guidance reflects human pharmacokinetic, clinical, official-label or evidence-review sources where available. A food pairing can change absorption or tolerability, but does not make a supplement necessary, effective or safe for every person.

06Supplement interaction check
Library interaction context156 ingredients · 0 mapped signals for this guide

An unlisted pair means no established pair-specific interaction was identified in this review—not proof that every dose, product or person is safe.

No pair-specific signal listedNo established interaction with another Dose Radar ingredient was identified in this review.

This is not proof that every dose, product or user context is safe. Medication and condition checks still apply.

07Research notes
Evidence verdict

Insufficient evidence for the stated context. That disease-specific result does not establish liver protection, longevity benefit or a routine supplement dose for healthy users.

The displayed amount comes from human research or an official evidence summary. It is not a personalized prescription, and formulation can change whether the comparison is valid.
