Core Nutritionals | Lifeline Liver | 90 Capsules

Core Nutritionals Lifeline Liver is a focused, fully disclosed liver support formula designed around three major priorities: hepatocellular protection, bile flow support, and antioxidant defense. Instead of hiding behind a proprietary blend stuffed with low-cost botanicals, Core uses five targeted actives and tells you exactly how much of each you are getting. That matches the brand’s philosophy well: transparent formulas for serious users who want measurable formulation logic, not label decoration.

The anchor is Milk Thistle at 1,260mg, standardized to 80% silymarin. That is a serious dose. Silymarin is the active flavonolignan complex in milk thistle, and its value comes from membrane-stabilizing, antioxidant, and hepatoprotective effects. In practical terms, it helps protect liver cells from oxidative damage and toxic insult while supporting normal liver enzyme status. The standardization matters just as much as the raw milligrams because 80% silymarin gives this formula a high-purity hepatoprotective backbone. In the liver support category, many products rely on token milk thistle doses with no meaningful standardization. This one does not.

Katuki Extract follows at 400mg, standardized to 5% kutkin. Katuki is a classic Ayurvedic liver-support botanical with a long history of use for bile support and hepatic resilience. Modern data are not as extensive as milk thistle or TUDCA, but the ingredient is respected for supporting liver enzymes, digestive function, and bile movement. Its inclusion makes sense because liver support is not just about neutralizing oxidative stress; it is also about supporting the flow pathways that help the liver process and eliminate waste efficiently.

Setria® L-Glutathione is included at 250mg, which sits right at the bottom of the commonly used 250-500mg clinical range. Glutathione is the body’s master intracellular antioxidant, a tripeptide central to redox control, detoxification, and immune regulation. It donates electrons to neutralize reactive compounds and helps protect cellular proteins, lipids, and DNA from oxidative stress. Oral glutathione is an ingredient where form matters, and Setria® is one of the most established branded versions on the market. Evidence for standard oral glutathione in healthy people is mixed because absorption can be challenging, but using a branded ingredient at a clinically relevant entry dose is still a major step above generic, unstandardized material.

TUDCA at 250mg is one of the most compelling inclusions here mechanistically, though the dose is below the 500-1500mg range most often used in human studies. TUDCA is a hydrophilic bile acid that supports bile composition and flow while acting as a chemical chaperone that reduces endoplasmic reticulum stress and helps preserve mitochondrial integrity. That matters because liver stress is not only about toxins; it is also about cellular stress signaling, apoptosis risk, and bile acid balance. The honesty point: 250mg is useful and directionally smart, but it is not a full clinical TUDCA dose by the standards of most published human data.

BioPerine® at 10mg rounds out the formula as an absorption support ingredient. Piperine is widely used to improve uptake of certain compounds and strengthen overall formula efficiency. It is not the star here, but it is a practical addition in a capsule formula where maximizing ingredient utility matters.

The synergy is clean and intentional: milk thistle protects hepatocytes, Katuki supports bile and traditional hepatic function, TUDCA strengthens bile acid physiology and cellular stress handling, glutathione reinforces intracellular antioxidant capacity, and BioPerine® helps the system work harder per serving. The transparency assessment is excellent: no proprietary blends, all doses disclosed, branded raw materials where they matter. What to expect: day one is subtle, not stimulant-like. Most users notice nothing dramatic acutely beyond easy capsule use. Over 2-4 weeks, this is designed to support better day-to-day digestive comfort with richer meals, improved tolerance during heavy supplement periods, and a stronger baseline of liver-focused antioxidant and bile support.
