As of Jun 2026, Unbox Health has lab tested and rated 17 products in the Vitamin C Supplements 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.
