Long-term or high doses of niacin (time-release preparations) have led to liver failure or hepatotoxicity in some individuals. It’s possible that niacin is changed into NAD, which can harm the liver in excessive amounts.

High levels of beta-carotene worsened alcohol-induced liver injury in rats, while lower doses were protective.

To sum it up, most vitamins aren’t dangerous in normal doses. Avoid megadoses, especially of niacin and beta-carotene.

A Note About Alcohol

Alcohol consumption is directly associated with liver disease.

It is safe to state that alcohol is possibly the most dangerous substance out there, based on the number of deaths it causes every year.

In Advanced nations, mortality due to liver diseases is directly proportional to alcohol consumption (30 grams of pure alcohol per day is seen as a”safe dose”). Serious alcoholic hepatitis has a mortality record of around 50 percent.

The fatty liver grows in 90 percent of individuals who drink more than 16 g of alcohol/day but resolves once they stop drinking.

Many Reports have promised that the liver toxicity of paracetamol (acetaminophen) is raised in chronic alcoholics. Individuals do not just carry an elevated risk of acute and fatal liver damage after acute overdoses, but liver damage can also occur at therapeutic doses.

This All goes to say that you need to avoid alcohol if you would like to look after your liver. An occasional drink is probably fine if you are healthy, but equally binge drinking and alcoholism may harm your liver faster than anything else.

Additionally, many of the supplements listed above become dangerous only when combined with alcohol or drugs.

Plus, some herbal products on the market don’t go through adequate quality control. Some may include heavy metals, poisonous solvents, and additives, or other contaminants — even if the real herbs recorded on the label are safe.

Herbal products are occasionally adulterated with additional toxic herbs of similar appearance (for example, germander utilized in skullcap goods ).

Blue-green algae species like spirulina could possibly be contaminated with liver-toxic compounds called microcystins, for which no greatest safe level is understood.

Some articles claim echinacea Is potentially poisonous to the liver, which is not true. Echinacea contains substances in the pyrrolizidine alkaloid family. However, its pyrrolizidine alkaloids in echinacea are benign.

If you have Liver disease, you have to be particularly careful of what you are taking. Ask for quality certificates, monitor your liver enzymes, and Talk to your physician about all of the supplements you’re taking to avoid drug interactions.
