NIH Office of Dietary Supplements
Tier: Authoritative (U.S. government)
What it is
The ODS, part of the U.S. National Institutes of Health, publishes evidence-based fact sheets on every major vitamin, mineral, and botanical.
Why we trust it
NIH ODS reviews the peer-reviewed literature, consults academic and clinical experts, and updates fact sheets on a rolling basis. It is the single most-cited non-regulatory reference for supplement science in the U.S.
What we use it for
Interactions (conflicts, synergies, companions), timing guidance, and backup Upper Limits when EFSA hasn't published one.
How Suvo applies it
NIH ODS is one of Suvo's main references for turning research into readable guidance. We use it to explain common nutrient interactions, food-related timing notes, and safety context for vitamins, minerals, and frequently logged botanicals.
Limits
NIH ODS fact sheets are broad references, not personalized medical advice. If a question involves a medication, pregnancy, surgery, or a diagnosed condition, Suvo treats the rule as educational and points users back to a qualified clinician.
