Our Editorial Standards

VitOptics publishes free guides about supplements, including how common prescription medicines and supplements fit together. This page explains who writes them, where the information comes from, how we keep them current and how to tell us about a mistake. VitOptics also sells personalized supplement packs, and the last section explains how that shows up in what we write.

Who writes our guides

Our articles are published under the byline VitOptics Staff. We research and draft them with AI tools, and every new article is checked against the sources it cites before we publish it.

No one who writes or approves our articles is a licensed clinician, and the articles are not reviewed by one. The guides explain what drug labels and public health sources say. They don't replace advice from your own doctor or pharmacist, who knows your health history.

How we choose topics

  • Supplements and the medicines you already take. For medication guides, we write about widely prescribed medicines whose labels or public health sources say something about vitamins, minerals or timing.
  • Questions people search for when choosing supplements. For example: what to look at before adding a supplement, how to check for duplicate ingredients, how personalized pack services compare, and what an online quiz can and can't tell you.
  • Only what we can source. We don't publish statements we can't support with a source. We don't publish articles that claim a supplement treats, cures or prevents a disease.

We never use customers' assessment answers, results or order details in our articles. If there's a question you'd like us to answer, email support@vitoptics.com.

The sources we use

  • Drug labels. For any instruction about timing, spacing or interactions, we go to the medicine's FDA-approved prescribing information, which we read on DailyMed, the National Library of Medicine's label database.
  • MedlinePlus. The National Library of Medicine's plain-language pages on medicines and supplements.
  • NIH Office of Dietary Supplements. Its fact sheets, for recommended amounts, upper limits and food sources of vitamins and minerals.
  • NIH National Center for Complementary and Integrative Health. For herbs and other supplements that aren't vitamins or minerals.
  • The FDA. For how dietary supplements are regulated and labeled.
  • Peer-reviewed research. Found through PubMed, when a question goes beyond what the sources above cover. We look first for systematic reviews and randomized trials in people, and we say plainly when the research is limited or mixed.

When a timing instruction comes from a drug label, we link the label so you can read the exact wording, and we often quote it directly. Our medication guides, and most of our other articles, end with a Sources list that links to each source, so you can read it yourself.

When we write about another company, we use its own website for facts about that company, such as its prices or what it sells. We never use it as evidence that a product works.

How we keep articles current

  • Every article shows the date it was first published.
  • When we change what an article says (a fact, an amount, a timing instruction or a source), we add or update its "Last updated" date.
  • Small edits that don't change the meaning, such as fixing a typo or a broken link, or adding a link to a related guide, don't change that date.
  • If we learn that a drug label or another source we cite has changed, we check the article against it.
  • Before we write about another company's prices, products or availability, we check its own website, and we give the date of that check where it matters most, as in our comparison table. Prices and services change, so confirm them on the company's site before you buy.

Corrections

If you spot an error, an outdated fact or a broken link, email support@vitoptics.com with the article's address and what looks wrong. We check every report against the source.

If we got something wrong, we fix the article and update its "Last updated" date. When a correction changes a fact, an amount or a timing instruction, we also add a short note at the end of the article saying what changed.

Please don't email us personal health details. Questions about your own medicines are best taken to your doctor or pharmacist.

Information, not medical advice

  • Our articles are general information. They are not medical advice, and they are not a substitute for advice from a doctor, pharmacist or other licensed clinician who knows your health history.
  • Don't start, stop or change a prescription medicine, or when you take it, because of something you read here. Take your questions and your supplement labels to your pharmacist or prescriber.
  • Supplements are not intended to diagnose, treat, cure or prevent any disease. The FDA does not approve dietary supplements for safety or effectiveness before they are sold.
  • If you think you may be having a medical emergency, call 911.

How we disclose that VitOptics sells supplements

VitOptics sells personalized daily supplement packs, built from a free online assessment. We publish these guides, and we benefit when readers become customers.

  • Many articles end with a section headed "Where VitOptics fits". It explains how our service handles the topic and links to our free assessment. We write the rest of the article to be useful whether or not you ever buy from us.
  • When an article compares VitOptics with other services, remember that we are one of the companies being compared. We link our sources so you can check them.
  • No company pays us to write about it, to include it or to rank it.

The guides are general. A VitOptics recommendation is built from your own assessment answers, and your result explains why each product is in your pack. About VitOptics explains how packs are built and checked.
