What Zynava Is

Zynava is a free supplement search and price-comparison engine. Tell us what you're looking for, and Zynava shows matching supplement options and prices from multiple retailers. Zynava does not independently verify product labels, evaluate research quality, or rate products for medical effectiveness.

Where Listings Come From

Product listings come from the catalogs of our participating retailers, which we access through affiliate partnerships. When you click out to a retailer and make a purchase, Zynava may earn a commission at no extra cost to you. See our Affiliate Disclosure for details.

Prices and product details come from retailer product feeds and are refreshed periodically. Prices can change at any time, so always confirm the final price on the retailer's site before buying.

How Search Results Are Ordered

Results are ordered by a combination of:

  • Relevance — how closely a product matches what you typed
  • Price — including price per serving, so a 500mg capsule and a 1000mg tablet can be compared fairly
  • Customer rating — as reported by the retailer
  • Availability — in-stock products are shown first

You can also sort and filter results yourself — for example by lowest price, best value per serving, or widest selection.

Ranking within results is never paid. Retailers and brands cannot pay to move a product up in Zynava's search results. Affiliate commissions do not affect ordering. Retailers are included on Zynava through affiliate partnerships, which is separate from how individual products are ranked within results.

What We Don't Do

  • We do not sell, manufacture, or distribute supplements.
  • We do not independently test products or verify what is inside any bottle. Product details shown on Zynava come from retailer listings.
  • We do not grade or rate the quality of scientific research. Our Research Library links to published studies for educational reference only.
  • We do not give medical advice. Nothing on Zynava is a diagnosis, treatment, or substitute for guidance from a qualified healthcare professional.
