As of Jun 2026, Unbox Health has lab tested and rated 11 products in the Peanut Butters category.
We buy every product from the open market, with no brand involvement. Every product is tested at up to 3 NABL-accredited labs. Products are then rated D to A+, based on the following dimensions: their label accuracy, their toxicity and their nutritional profile (in the case of food products). All lab reports are published.
