TUDCA (Tauroursodeoxycholic Acid) calculator
TUDCA (Tauroursodeoxycholic Acid) math uses the listed vial sizes on this card and the liquid you type. Concentration in mcg per mL is vial milligrams times 1000, divided by milliliters. A U-100 syringe has 100 marks per milliliter, so each unit is that concentration divided by 100. Example numbers so you can see the math: a 250 mg listing plus 2 mL of liquid. Change any number and the units change. Try the numbers. A research-market vial is not the same material used in a trial.

Units chart for listed TUDCA (Tauroursodeoxycholic Acid) sizes
U-100 math for listed TUDCA (Tauroursodeoxycholic Acid) sizes. Each cell is micrograms per syringe mark if you add that much liquid. The table does the same math as the calculator. It does not pick an amount for you.
| Listed vial | 1 mL liquid | 2 mL liquid | 3 mL liquid |
|---|---|---|---|
| 250 mg | 2500 | 1250 | 833.3 |
| 500 mg | 5000 | 2500 | 1666.7 |
What is TUDCA (Tauroursodeoxycholic Acid)?
Other names in the library: tauroursodeoxycholic acid, TUDCA - 250mg, TUDCA - 500mg, TUDCA. Evidence describes the named substance, not a quality certification or equivalence assessment of commercial stock. Listed sizes: 250 mg, 500 mg. A seller title is a listing. It does not prove the vial matches a paper.
Taurine-conjugated bile acid investigated in disease-specific settings.

What the cited papers actually measured
We mark the cited papers as C for 34 ALS patients receiving riluzole in an early proof-of-principle randomized trial. and An early small ALS study reported benefit, but the later 336-participant Phase 3 trial did not meet its primary or secondary endpoints.. The larger study did not confirm the early signal. Recruitment and attrition during COVID limited precision. These disease-specific trials do not establish general liver or wellness benefits. An early study examined functional decline. A small early disease-specific study is not proof of liver detoxification or a confirmed current ALS treatment. Later trial outcomes must be checked before any treatment conclusion. The Phase 3 TUDCA-ALS trial did not show significant benefit on its primary functional endpoint or secondary survival and biomarker endpoints. Top-line consortium report; pandemic recruitment and attrition limited precision. EU-funded research, not a commercial-product equivalence study. Risks on the record: Human safety for this exact preparation is incompletely characterized. A lack of reported problems does not establish safety.

Questions people ask
Is TUDCA (Tauroursodeoxycholic Acid) FDA-approved?
not established. No approval for this exact marketed preparation or claimed wellness indication is established in this source set.
Does PepBear pick an amount of TUDCA (Tauroursodeoxycholic Acid)?
The calculator turns numbers you type into U-100 units. Trial or label amounts stay as cited facts.
How many units is a listed TUDCA (Tauroursodeoxycholic Acid) vial after you add water?
Units = (amount in mcg ÷ (vial mg × 1000 ÷ water mL)) × 100 on a U-100 syringe. Enter the three numbers. The chart shows the same math for each listed vial size and 1, 2 or 3 mL of liquid.
Why flag amounts under 5 units?
A U-100 barrel is easy to misread below about 5 marks. That is a measuring warning. The page does not tell you to take more.
