TUDCA (short for tauroursodeoxycholic acid) is a bile acid that's commonly sold as a "liver support" supplement. It's used clinically (in medication forms) for certain cholestatic liver conditions, and supplement brands often market it for bile flow, digestion, and general liver support. In the supplement aisle, TUDCA products range from simple single-ingredient capsules to high-dose blends that stack multiple "liver detox" ingredients together.
The rankings below use 500 mg/day as a consistent comparison point so products can be compared on the same monthly-cost basis. Typical supplement dosing often falls somewhere around 250-1500 mg/day, but the right choice depends on your goals, tolerance, and what your clinician recommends if you're using it for a specific medical reason.

1) Confirm the label says "tauroursodeoxycholic acid" (TUDCA), not just a look-alike. TUDCA is sometimes confused with other bile-acid terms. If you're shopping specifically for TUDCA, the Supplement Facts panel should spell out tauroursodeoxycholic acid (or use "TUDCA" clearly as the ingredient name), rather than relying only on front-label marketing.
2) Check the serving size before comparing value. Many products list the TUDCA amount per serving, but the serving might be 2 capsules instead of 1. That changes how long a bottle lasts and can make "60 capsules" look cheaper than it is. The tables account for servings-per-container, but it's still worth double-checking the serving size so you know what you'll actually take each day.
3) Decide whether you want single-ingredient TUDCA or a "liver support" blend. Some products pair TUDCA with ingredients like milk thistle, NAC, taurine, artichoke, choline, dandelion, or other bile salts. Combos aren't automatically bad, but they can raise cost and make it harder to judge value if you mainly want TUDCA. If you prefer a cleaner stack, it's often simpler to choose a standalone TUDCA and add other supplements intentionally (for example, NAC or Glutathione (Liposomal)) rather than paying for a bundle.
4) Treat "extra-high mg" products as a serving-size and tolerance question, not automatically a better deal. Some labels list 1000 mg, 1500 mg, or even more per serving. That can lower the monthly cost at a fixed comparison dose, but it may be more than you personally want to take at once. If you prefer a lower daily amount, or you want to split doses, a lower-milligram capsule can be easier to use consistently.
5) Use quality signals as tie-breakers after the label is clear. If multiple products look similar on cost, look for the basics: a straightforward Supplement Facts panel, clear dosing instructions, and whatever manufacturing/testing signals you personally value (for example, third-party testing claims, GMP language, and a brand you trust). These aren't proof of effectiveness, but they can help separate "cheap but unclear" from "reasonably priced and transparent."
Most TUDCA products are capsules. Powders can make dose adjustment easier, but they may be less convenient and can taste unpleasant. Gummies are available in some listings, but they often come with sweeteners and lower active amounts per serving - so check the table before paying extra for convenience.
Evidence for TUDCA supplementation is moderate overall. There's established clinical use of related bile acid therapies for specific cholestatic liver conditions, and supplement research is expanding, but the over-the-counter market includes many formulations that aren't standardized the same way as prescription products. The 500 mg/day benchmark here is for cost comparison, not a promise that 500 mg/day is the ideal dose for everyone.
Because TUDCA affects bile acids and digestion, some people experience gastrointestinal side effects (for example, loose stools or stomach upset), especially when starting or when using higher doses. If you are pregnant or breastfeeding, have liver or gallbladder disease, are planning surgery, or take prescription medications, talk with a clinician before adding TUDCA. If you choose a combo formula, review the full Supplement Facts panel carefully to avoid duplicated ingredients or interactions across your supplement stack.
