How We Research Supplement Products
Each WSNC listing helps you understand a particular product and reach its authorized store page. We separate product facts from ingredient background so you can see what a source actually establishes.
Start with the current product label
The manufacturer listing and the package you receive are the sources to consult for the current formula, serving directions, Supplement Facts, other ingredients, allergens and dietary suitability. We link to the matching product in the authorized WSNC inSITE store on each product page. Product formulations and package sizes can change; check the current label before purchasing or using a product.
What ingredient research means
When a product overview names a nutrient or botanical with a relevant public resource, the product page may link to an NIH Office of Dietary Supplements fact sheet ↗ or an NIH National Center for Complementary and Integrative Health resource ↗. Those resources explain ingredients in general. They do not establish that the finished WSNC product was tested, prove a benefit from its particular formula or confirm its ingredient amount.
Some products, including multi-item protocols, veterinary formulas and foods, do not have a suitable individual human supplement fact sheet. On those pages, the product-specific details and authorized WSNC store listing remain the primary references. We do not attach an unrelated human fact sheet simply to fill a citation slot.
Dates, claims and editorial review
A price-check date reflects when the price inventory was checked; it is not a date on which a practitioner reviewed every ingredient or claim. We do not assign an author, clinical reviewer or editorial review date to a product without a corresponding review record. General ingredient research does not substantiate every product benefit. Read product benefits alongside the authorized store listing and discuss questions about medical conditions, medication interactions or dietary fit with an appropriately licensed professional.
How to compare products
- Read the specific product overview and open its WSNC inSITE listing.
- Compare the serving size, formula and ingredients on the current label.
- Check allergens, animal-derived ingredients and other dietary considerations on the package.
- Use NIH references for background on named ingredients, then ask a practitioner whether the product fits your circumstances.
