Pravastatin and Vitamin B3: what the published research says

PubMed indexes 4 records that name Pravastatin and Vitamin B3 together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Pravastatin and Vitamin B3. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

4 studies naming Pravastatin and Vitamin B3.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Effects of pravastatin with niacin or magnesium on lipid levels and postprandial lipemia.

The American journal of cardiology · 1995 · PMID 7653448

Clinical TrialComparative StudyRandomized Controlled Trial

“Thus, in this group of patients with clustered risk factors, the combination of pravastatin and niacin resulted in significant improvements in HDL and triglyceride levels, total cholesterol to HDL ratio, small dense LDL levels, and postprandial lipemia. Pravastatin alone or in combination with magnesium resulted in less significant changes that were largely limited to LDL cholesterol reduction.”

O'Keefe et al. · From the abstract

Names both Pravastatin and Vitamin B3 in its title.

Comparison table: Some lipid-lowering drugs.

The Medical letter on drugs and therapeutics · 2019 · PMID 30845107

Comparative StudyHuman subjects

Names Pravastatin and Vitamin B3 together in an interaction, co-administration, or pharmacokinetic context.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Pravastatin, Vitamin B3, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
