About

I'm Witsanu Janjam, the founder and editor of NAD Health Guide. I am not a medical doctor or licensed clinician. I am a health content researcher who built this site to translate peer-reviewed longevity science into clear, useful information for general readers.

My interest in mitochondrial biology and NAD+ metabolism started with curating research for personal use — wanting to understand what supplements like NMN, NR, and sulforaphane actually do, what the clinical evidence actually shows, and where the marketing claims diverge from the science. NAD Health Guide grew out of those notes.

What I Do Here

• Select article topics based on emerging research and reader questions
• Review primary literature from PubMed, ClinicalTrials.gov, and peer-reviewed journals
• Curate and edit content to accurately reflect clinical evidence
• Fact-check dosages, mechanisms, and study results against original sources
• Maintain the editorial standards documented on this site

What I Am Not

I want to be clear about boundaries. I am not a physician, pharmacist, registered dietitian, or licensed healthcare provider. Nothing I publish should be treated as personalized medical advice. I am a researcher and content editor — my role is to help readers understand what the peer-reviewed evidence says so they can have better-informed conversations with their own healthcare providers.

Editorial Approach

The supplement industry often moves faster than the science supporting it. My editorial approach is to separate what has credible human clinical evidence from what remains speculative — even when a mechanism sounds compelling in mice or cell culture.

When the evidence is strong, I say so clearly. When it's preliminary — animal studies, small pilot trials, or emerging mechanisms — I label it that way. I believe readers deserve to know the difference between "clinically proven in large trials" and "theoretically plausible based on mouse studies."

Disclosure

I receive no compensation from supplement manufacturers, clinics, or longevity companies. NAD Health Guide may earn affiliate commissions from some retailer links (fully disclosed), but editorial content is never influenced by commercial relationships.

A Note on AI-Assisted Research

Like most modern publishers in 2025–2026, my workflow uses AI tools for literature summarization and drafting efficiency. Every article is reviewed by me against cited peer-reviewed sources before publication — AI does not make editorial or factual judgments independently. I believe transparency about this process is more responsible than concealing it.

Why I Started This Site

I grew up watching relatives age with conditions that were at least partly preventable — metabolic disease, cognitive decline, loss of mobility. In my thirties I started reading longevity research seriously, first out of personal curiosity, then to make better lifestyle and supplement decisions for myself and my family.

What I found was overwhelming: the genuine science is fascinating and fast-moving, but it's buried under a layer of supplement-company marketing that distorts what the studies actually say. A single compound might have three clinical trials showing modest effects, and a dozen influencer posts claiming it "reverses aging." Separating these two layers is tedious, but for anyone making real decisions about what they put in their body, it matters.

NAD Health Guide is my attempt to do that separation publicly — to write the kind of guides I wish had existed when I first waded into this topic.
