Liver, Herbal supplement, Clinical trial, Liver enzymes


Background: The liver is responsible for many critical functions within the body. If the liver becomes diseased or injured, loss of those critical functions can cause significant damage to the body. KaraLivTM is a novel herbal formulation which contains a blend of different herbal extract ingredients. The current study tested the safety and efficacy of KaraLivTM versus a placebo control in supporting liver function.

Methods: The study is a randomized, double-blind, parallel, and placebo-controlled study. A total of 60 patients were divided into 2 groups of 30 each. One group was given KaraLivTM and the other group was given a placebo for a period of 56 days. Treatment results were assessed by evaluating the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, and alkaline phosphatase (ALP) in both groups.

Results: The herbal supplement KaraLivTM significantly supported healthy liver function compared to the placebo following the 56 days of treatment. The treatment (KaraLivTM) group showed a statistically significant improvement in assessed liver enzyme levels compared to the placebo group.

Conclusions: The all-natural herbal supplement KaraLivTM is a safe and effective product that can significantly help support healthy liver function.
