Niacin is a naturally occurring nutrient known as vitamin B3.

This vitamin supports and protects the nervous system, regulates blood circulation, and is essential for metabolizing proteins and carbohydrates.    

Receiving adequate amounts of niacin is crucial for overall health and wellness.

In this article, we’ll review a list of herbs high in niacin as well as the health benefits of niacin.

Herbs high in niacin

Niacin Overview:

Niacin is a water-soluble B vitamin found in plants, grains, animals, and dairy. It is essential for optimal human health. 

As one of the eight B vitamins, niacin plays a critical role in energy production, neuron health, and DNA production and repair. 

Niacin deficiency can lead to various health complications, like pellagra, skin and gastrointestinal issues, brain fog, headaches, and behavioral changes. 

Since niacin is water-soluble, the body doesn’t store the molecule in the body. Given this information, it’s crucial to ingest plants, foods, and herbs high in niacin to prevent complications and benefit from its numerous properties.

Below is a list of herbs high in niacin. Add these to your diet to improve your daily niacin intake.

Health Benefits of Niacin:

Niacin, or vitamin B3, is naturally found in many plant and animal sources and can be created from the amino acid tryptophan. Humans are able to absorb this vitamin when we consume plants and herbs high in niacin and can produce niacin internally from tryptophan. 

Other names for niacin incluse nicotinic acid or nicotinamide.

One of the primary niacin benefits is its ability to support the nervous system by protecting and supporting neurons through their life cycle (development, survival, and cell death).

Niacin is almost fully absorbed into the bloodstream by the small intestines and stomach, so niacin deficiency is rare in industrialized countries. 

Food sources of niacin include red meat, poultry, fish, brown rice, nuts, legumes, seeds, and bananas. Since the body can also convert the amino acid tryptophan into niacin, foods like dairy, oats, and chocolate are also beneficial.

Research shows that niacin supports energy and DNA production, regulates cholesterol levels, has antioxidant effects, protect against neurodegenerative diseases, and reduces blood pressure

Vitamin B3 deficiency may result in a health condition called pellagra, a systemic issue that causes mental confusion, abdominal pain, diarrhea, and skin sores, and may lead to death.  

Since niacin is water-soluble, the body easily absorbs it into the bloodstream. However, high water solubility means niacin is easily excreted and not stored in the body. This makes it important to eat vitamin B3 rich foods and herbs on daily basis.


Your daily niacin requirements differ based on your gender, age, and whether or not you are pregnant or breastfeeding. Niacin is measured in milligrams (mg) and niacin equivalents (NE). 1mg equals 1NE.  

Below is a helpful chart.

Age GroupRDA (mg or NE/day)
Men (19+ years) 15 – 20 NE/mg
Women (19+ years) 13 – 15 NE/mg
Children8 – 15 NE/mg
Infants 650 micrograms 
Pregnant Women 18 NE/mg 
Breastfeeding Women17 NE/mg

It is important to note that these are the recommended daily allowances, which are the minimum amount of a nutrient a person needs to avoid a deficiency. Some individuals may need more or less depending on their needs and health conditions.


Supplementing with herbs high in niacin may prevent detrimental health issues and support the nervous and circulatory systems.

Since the body absorbs high amounts of ingested niacin, consuming plants, foods, and herbs rich in niacin will support numerous health functions.

While niacin supplements are available and sufficient, it will benefit the body to consume a well-rounded diet of natural niacin sources to receive a full spectrum of benefits.
