To maintain normal liver and metabolic functions, Liver Vital Pro combines choline, L-cysteine, sodium R-alpha lipoate and a powerful vitamin and mineral complex.

The formula is optimized with well-known herbal liver vital substances from artichoke extract*, milk thistle extract*, schisandra extract* and dandelion extract*. 

Liver Vital Pro contains choline in the form of the patented branded ingredient VitaCholine®. Choline is an important nutrient for liver function and also has a major influence on lipid and homocysteine metabolism. With a low-choline diet, healthy individuals can develop liver dysfunction. [[D172]] 

The European Food Safety Authority (EFSA) has scientifically investigated and confirmed the effect of choline:  

• Choline contributes to the maintenance of normal liver function 
• Choline contributes to normal fat metabolism 
• Choline contributes to normal homocysteine metabolism 

R-alpha lipoic acid is a powerful antioxidant that helps protect liver cells from oxidative stress. On the other hand, it promotes the body's natural synthesis of glutathione, much like L-cysteine, which serves as the primary precursor for glutathione formation.  

Glutathione, acting as an antioxidant, plays a vital role in shielding liver cells. More significantly, it directly bolsters the liver's detoxification capabilities. [[D032]] [[D033]] 

*While health claims regarding plants and plant substances haven't been conclusively evaluated, the abundance of research in this area leads many experts to believe in their proven effectiveness.  

• Milk thistle extract: Research suggests that silymarin, found in milk thistle, plays a significant role in safeguarding liver cells as an antioxidant. Additionally, it stimulates the production of enzymes essential for metabolizing harmful substances. [[B915]]  
• Artichoke extract contains cynarin and luteolin. These bitter compounds can stimulate appetite, alleviate bloating and indigestion, and provide relief to the liver. Artichokes are rich in antioxidants, which can also protect liver cells from oxidative stress. [[D173]] 
• Dandelion extract contributes to the normal function of the liver: Dandelion herb stimulates bile production in the liver, thereby supporting the organ's detoxification function within the body. Contains antioxidants that help protect liver cells from oxidative stress. [[D179]] [[D987]] 
• Schisandra extract: Schisandra contains secondary plant substances with positive effects on the liver. Flavonoids such as quercetin and hesperetin in particular are said to have antioxidant properties that help protect liver cells from oxidative stress. [[D985]] 

Vitamins and minerals support the functions of the liver both directly and indirectly.  

B vitamins  

... aid in the conversion of the metabolic intermediate homocysteine into cysteine. The body produces the amino acid glutathione from cysteine. From cysteine, the body produces the amino acid glutathione, which acts as an antioxidant, protecting liver cells and directly supporting liver detoxification: Glutathione's sulfur components cause it to become adhesive, allowing toxins to adhere to the glutathione molecule for transport through the body and eventual excretion. [[D032]] [[D033]] 

The health claims for vitamins have been scientifically examined and confirmed by the European Food Safety Authority (EFSA): 

• Vitamin B6 (pyridoxine) contributes to normal cysteine synthesis and normal homocysteine metabolism. [[D946]] 
• Vitamin B12 (cobalamin) contributes to normal homocysteine metabolism. [[D946]] 
• Quatrefolic® folic acid (vitamin B9) contributes to normal homocysteine metabolism. [[D946]] Liver Vital Pro contains milk thistle extract in the form of the patented branded ingredient Quatrefolic®. 

Minerals  

... like selenium and zinc function as antioxidants, shielding the liver from oxidative stress triggered by free radicals. As a component of glutathione peroxidase, selenium also plays an essential role in combating harmful oxygen radicals. Zinc is also important for normal metabolic functions; a zinc deficiency can therefore lead to a deterioration of numerous liver functions. [[D988]]  

The health claims for minerals have been scientifically examined and confirmed by the European Food Safety Authority (EFSA): 

• Selenium contributes to the protection of cells from oxidative stress. [[D946]]  

• Zinc plays a role in safeguarding cells against oxidative stress and supports normal fatty acid, carbohydrate, acid-base, and vitamin A metabolism, as well as the metabolism of macronutrients. [[D946]]
