Turkey is probably the best-known source of tryptophan. To convert from tryptophan to niacin, you need to get adequate amounts of iron, riboflavin (B2), and pyridoxine (B6).

Niacin deficiency is rare in the U.S. because it is readily available in many foods, including meat, legumes, and grains. However, some people may have trouble getting enough niacin, especially those who are malnourished due to a health condition. In these cases, niacin supplements may be beneficial. Dietary supplements are not regulated in the United States, meaning the Food and Drug Administration does not approve them for safety and effectiveness before products are marketed. When possible, choose a supplement that has been tested by a trusted third party, such as USP, ConsumerLabs, or NSF. However, even if supplements are third-party tested, that doesn’t mean that they are necessarily safe for all people or effective in general. Therefore, it is important to talk to your healthcare provider about any supplements you plan to take and check in about any potential interactions with other supplements or medications. • Active ingredient(s): Nicotinic acid • Alternate name(s): B3, nicotinic acid, nicotinamide, nicotinamide riboside • Legal status: Available over the counter (OTC) • Suggested dose: 14-16 milligrams (mg)/day • Safety considerations: Niacin can interfere with some medications, and high doses can lead to complications In a 2020 study published in Alzheimer's and Dementia, researchers looked at whether niacin had therapeutic potential in Alzheimer's disease.

Niacin, or vitamin B3, is a water-soluble Recommended Amounts RDA: Niacin is measured in milligrams (mg) of niacin equivalents (NE). One NE equals 1 milligram of niacin or 60 mg of tryptophan. The Recommended Dietary Allowance (RDA) for adults 19+ years is 16 mg NE for men, 14 mg NE for women, 18 mg NE for pregnant women, and 17 mg NE for lactating women. UL: The Tolerable Upper Intake Level is the maximum daily intake unlikely to cause harmful effects on health. The UL for niacin for all adults 19+ years is 35 milligrams. Niacin and Health Cardiovascular disease For more than 40 years, niacin in the form of nicotinic acid has been given to patients to treat a condition called dyslipidemia, a major risk factor for Nicotinic acid supplements contain high amounts, up to 1,000-2,000 mg of niacin taken daily. Studies have shown that they can increase HDL cholesterol and lower LDL cholesterol and triglycerides. However, negative side effects (skin flushing, stomach upset, diarrhea) usually accompany the supplements, resulting in poor compliance from patients. Clinical trials have not consistently shown that nicotinic acid leads to less cardiovascular events or deaths from CVD. • Though earlier clinical trials showed a reduction in CVD events and deaths with niacin therapy, two more recent large clinical trials on CVD outcomes concluded differently. [3,4] Both were large randomized placebo-controlled trials, following participants for up to 4 years. Niacin supplements were given...
