Double Wood Supplements TUDCA is a tauroursodeoxycholic acid supplement designed to support liver wellness and healthy bile flow, with 250mg in each capsule.
TUDCA is a water-soluble bile acid for people looking to support liver and digestive wellness as part of a balanced routine. Its stated role includes supporting healthy bile flow from the liver to the intestines, making it relevant to buyers focused on bile flow as well as broader digestive support.
Double Wood Supplements TUDCA is formulated to support liver wellness and healthy bile flow from the liver to the intestines. Bile flow support also contributes to digestive wellness as part of a balanced routine. The product is a supplement for wellness support, not a stated treatment for a medical condition.
Take two capsules for a 500mg serving on an empty stomach, as directed. Each capsule contains 250mg, and the 60-capsule bottle provides a one-month supply at the stated serving size. This gives shoppers a clear way to plan the product within a regular routine.
Double Wood Supplements tests every batch for purity, potency, heavy metals, and microbial safety, using third-party ISO/IEC 17025 accredited labs and openly published certificates of analysis (COAs). The formula is tested at 99.7%+ purity and contains no proprietary blends. Authentic TUDCA has a distinctly bitter taste, a characteristic buyers may notice when taking the capsules.
TUDCA also pairs naturally with NAC and Milk Thistle in a liver wellness regimen; together, these ingredients support liver function and antioxidant defenses. This pairing is a routine option for shoppers who already use those supplements, rather than a required part of taking TUDCA.
This product suits adults seeking a measured TUDCA supplement for a liver and digestive wellness routine, particularly those who value batch testing and accessible COAs. Its defined serving, water-soluble bile acid ingredient, and stated empty-stomach direction make it straightforward to place in that routine.
