1 vendor list TUDCA. Too few publish a comparable price to give a range. Last read Sep 28, 2026.
A bile acid sold for liver support, with an approval history worth reading.
Every offer, by form
None of these listings is a vial, so each form is shown in its own section and none is priced per milligram.Capsules and tablets
Priced per bottle. The size shown is what the listing states, usually one capsule or tablet, so a price per milligram would not compare with a vial.

Coverage record →Three things the price does not tell you
A cheap sticker price only counts if the package is right.The label is a claim, not a measurement
The amount printed on the pack is the vendor's claim, not a lab measurement. Compare offers by what each label states before judging value.
Shipping and card fees are not in these numbers
Shipping is often flat, so it hurts small orders most. Several vendors add a card fee and discount for crypto. Two offers a dollar apart can swap places at checkout.
Bigger packages look cheaper and expire just as fast
Compare capsules and tablets by the amount per unit and the count per pack. A larger package only saves money if you can use it within the product's labeled shelf life.
What you are actually buying
Regulatory status changes what a price means.
Supplement
Sold in the US as a dietary supplement, with no FDA approval for any use on its own. The molecule does have an approval history, and it is not the one vendors describe. Under the name taurursodiol it was one half of Relyvrio, a fixed combination with sodium phenylbutyrate that the FDA approved on 29 September 2022 for ALS on the strength of a single phase 2 trial. The confirmatory phase 3 trial, PHOENIX, missed both its primary and its secondary endpoints. The company reported that to the FDA on 30 April 2024, stopped marketing on 31 October 2024, and the approval was formally withdrawn on 29 August 2025. That approval belonged to a two-ingredient product and to one disease, and it no longer exists.
Full TUDCA record →Nobody stands behind a research product
There is no pharmacist behind it, no dispensing record, and nobody on the hook for what is inside the pack. The lab report is the whole quality system, which is why it sits next to the price here.
Research use only is a claim the seller has to keep making. A vendor that adds dosing instructions, health claims, or personal-use wording has stepped outside the framework it relies on, and that says something about the seller.
What customs and carriers do varies by state and by shipper. This describes how these products are sold and is not legal advice.
Before the pack arrives
The tracked offer is for capsules, not a vial.
Follow the pack's storage directions
Check the capsule pack's label for storage and use-by information. A freeze-dried vial's freezer and post-mixing timeline does not describe this listing.
No vial to mix
The tracked product is sold as capsules. Bacteriostatic water, syringes and reconstitution instructions are not part of this offer.
Check the count and amount per capsule
Compare the stated amount in each capsule and the number of capsules in the pack against its total price. A vial-size or per-milligram powder comparison would misrepresent this format.

How this table is built
What decides the order of the rows, and who gets to be in them.Cheapest per mg first, and nothing else
Rows sort on one number. There is no combined score and no weighting, so no vendor can be pushed up the table by a rating you cannot check.
Doing badly does not get a vendor removed
Vendors that publish nothing stay in the table, marked. Taking them out would make the market look tidier than we found it.
Every price has a date on it
Prices are read off public catalog pages and saved with the date. If a check runs late the row says so instead of showing an old price as current.
Sorting never reads who pays us
Commissioned links are marked on the row and listed on the disclosure page. They never move a listing up or down the table.
How these prices are collected
Prices on this site are read from vendor websites on the dates shown. A starting tag means the vendor publishes only a from price for that product. A wall means the vendor hides prices behind a login, and we publish that fact rather than hide the gap.
We report prices and never rate or score an offer. There is no value grade, no ranking of vendors by our opinion. A row carries its size, its price, its price per milligram, and any plain fact about the listing worth knowing.
When a vendor's site disappears, its rows stay in the tables as a dated record, drop out of every count, price range and ranking, and lose their links. Ninety days after a vendor's site disappears, its rows leave these tables and remain in our records.
Some vendors pay this site a commission when you buy through our links. Every one of those links is marked, and every vendor with that arrangement is labeled on the vendor page. Commissions never change the prices we show, the order of any table, a vendor's badge, or anything in the audit record. The data is collected the same way for every vendor, paid or not.
We accept no payment for coverage, placement, or ratings. Warning letters come from fda.gov. If a paying vendor earns a bad mark, the mark stays.
Questions about buying tudca
Cost, sizes, and how this table works.How much does TUDCA cost?+
We track 1 listing across 1 vendor, which is too few to publish a reliable per milligram range. The table above shows every price we have read.
Why is the same product so much cheaper at one vendor?+
Package size, sale cycles, payment method discounts, and how much testing evidence a seller publishes all move the number. A cheap price is only cheap if the product holds what the label claims, which no price column can tell you.
Do you make money if I buy?+
Sorting never reads whether a vendor pays us. Any commissioned link is marked on the row and listed on the disclosure page, and it never changes where a listing lands in the table.
Is tudca legal to buy?+

How current are these prices?+
Every price is read off a public catalog page and stored with its date; this compound was last read Sep 28, 2026. Nothing is overwritten, so a stale row says so rather than pretending to be current.
