As of Jun 2026, Unbox Health has lab tested and rated 7 products in the Apple Cider Vinegar 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.

There are no RDA (Recommended Dietary Allowance) guidelines for Apple Cider Vinegar. Due to ACV's highly acidic nature, research suggests that the average adult should consume no more than 1–2 tablespoons of ACV per day.
