Liver diseases reduce blood levels of vitamins

Summary This study evaluated the relationship between liver diseases and blood levels of vitamins in children. Vitamins A, D and E were investigated in young patients with hepatitis and biliary atresia, a childhood disease of the liver in which the biliary system is compromised. The results showed that children suffering from these liver diseases had…

Selenium and zinc protect against oxidative stress

Summary This study evaluated the protective effect of selenium and zinc against oxidative stress (imbalance between free radicals production and the body´s antioxidant defenses). The experiments were performed with rats that received cadmium, zinc and selenium in their drinking water for a period of 35 days. The results showed that selenium and zinc together protected…

Tea compounds protect against hepatitis

Summary This study examined the effects of catechins (tea compounds) against hepatitis, the inflammation of the liver. The experiments were performed with ducklings which were given either catechins or no treatment. The results showed that tea catechins had significant protective effects against hepatitis. More details can be found in the study. References J Li, L Zhou, Y…

Carnitine supports liver regeneration

Summary This study evaluated the effects of carnitine on liver regeneration. The experiments were performed with rats that were given either carnitine or no treatment after hepatectomy (resection of the liver by surgical operation). The results showed that carnitine increased the regeneration of the liver. Further details can be found in the study. References O…

Natural compounds are effective against liver disease

Summary This study investigated the effects of the natural compound silybin-phospholipids and vitamin E in 40 patients. The results showed that vitamin E and silybin-phospholipids had protective and anti-inflammatory effects in patients with liver disease. More details can be found in the study.

Liver diseases are associated with low levels of vitamin D

Summary This publication collected scientific studies on blood concentrations of vitamin D in patients with gastrointestinal and liver disorders. The researchers discovered that low blood levels of vitamin D (hypovitaminosis D) are common among patients with gastrointestinal and liver disease. More details can be found in the study.

Micronutrient supplementations decrease health risks associated with hepatitis

Summary This study analyzed the effects of the standard treatment of hepatitis (pegylated interferon combined with ribavirin) on the blood levels of specific micronutrients (i.e. B vitamins and iron). 152 healthy participants and 109 patients with hepatitis C, an inflammatory disease of the liver, were investigated. The results revealed that hepatitis treatment depleted micronutrient levels…

Micronutrients protect against liver damage

Summary This study evaluated the effects of a nutrient mixture on liver injury. The nutrient mixture contained micronutrients such as lysine, proline, vitamin C, and green tea extract. For 2 weeks, mice were given either a regular diet or a diet supplemented with micronutrients. The results showed that the nutrient mixture can be useful in…

Betaine protects the liver

Summary This study evaluated the effects of the natural compound betaine on liver diseases. The experiments were performed with rats. The results showed that betaine inhibited oxidative stress (imbalance between free radicals production and the body´s antioxidant defenses), which plays an important role in the development of liver injury. Further details can be found in…

Micronutrient supplementation prevents liver injury

Summary This study investigated the role of micronutrients, such as selenium, vitamin C (ascorbic acid), beta-carotene and alpha-tocopherol (vitamin E), on liver injury. The experiments were performed with rats. The results suggested that supplementation with micronutrients can prevent the development of liver injury. Further details can be found in the study. References Tunc Catal, Sehnaz Bolkent…

A green tea compound prevents liver toxicity

Summary This study evaluated the effects of epigallocatechin gallate (EGCG), a compound found in the green tea, on liver damage. The experiments were performed with rats. The results showed that EGCG prevents liver damage and can be useful in treating patients with liver diseases. Further details can be found in the study. References Jun-Won Yun, Young-Kyung…

Green tea extract inhibits liver fibrosis

Summary This study evaluated the effects of epigallocatechin gallate (EGCG, a compound found in green tea) on liver fibrosis, which is the development of scar tissue in the liver in response to injury or disease. The experiments were performed with rats. The results showed that EGCG can be useful in the prevention and treatment of…

Glutamine enhances the antioxidant defenses

Summary This study evaluated the effects of the amino acid glutamine on oxidative stress (imbalance between free radicals production and the body´s antioxidant defenses) during ischemia-reperfusion of the liver. Ischemia-reperfusion is the restoration of blood flow to body tissues that were blood flow-deficient. Ischemia-reperfusion damages organs and tissues (e.g. increasing oxidative stress) and is often…
