Niacin

Cholesterol and triglycerides is the main area connected here, and any felt benefit should be read together with the human evidence base.

Human evidence exists, but it is mostly in patient or disease contexts, so the score is handled conservatively.

Representative tier calculated from paper evidence that passed the collection audit.

Tolerable Upper Intake Level (UL)1 papers
The Norwegian Scientific Committee for Food Safety reviewed existing human dose-response studies to propose upper intake limits for nicotinic acid (10 mg/day) and nicotinamide (900 mg/day) to prevent adverse effects like flushing and liver toxicity.human · unknown

Generalized pruritus was reported in 75% of the niacin group versus 0% in the placebo group (P < .001).human · rct
Gastrointestinal upset1 papers
Gastrointestinal upset occurred in 30% of participants receiving niacin compared to 3% in the placebo group (P = .005), noted as the most severe adverse effect in the study.human · rct

Key Evidence #1
Public scholarly dataCitation signal: 662
observational

The risk of myopathy was increased by adding ERN/LRPT to simvastatin 40 mg daily (with or without ezetimibe), particularly in Chinese patients whose myopathy rates on simvastsatin were higher.

Key Evidence #2
Public scholarly dataCitation signal: 221
observational

In randomized controlled trials, triglyceride lowering is associated with lower risk of major vascular events, even after adjusting for LDL-C lowering, although the effect is attenuated when REDUCE-IT is excluded.

Key Evidence #3

It is suggested that nicotinamide will be useful as a cosmeceutical ingredient to attenuate skin aging and hyperpigmentation, especially in the elderly or patients with reduced NAD+ pool in the skin due to internal or external stressors.

The link between dietary niacin intake and migraine in US adults is L-shaped, with an inflection point of roughly 21.0 mg/day, and this study used cross-sectional data from people over 20 years old who took part in the National Health and Nutrition Examination
