In a new study, researchers discovered that more than half of the nutritional supplements tested did not disintegrate properly. Included in the tests were 39 tablets and 10 capsules containing minerals and vitamins commercially available on the Canadian Market. The first disinteration test used simulated intestinal fluid (sif) at a pH of 6.8 for 20 minutes. Products which did not disintegrate were further analyzed using USP disintegration condition for dietary supplements.
Of the 39 tablets tested only 18 products (which included USANA's Multi-Mineral which I highly recommend) disintegrated fully at the first stage. The 21 tablets that failed the first stage were then tested using USP conditions. Nine tablets still failed to disintegrate, including all three time release products tested.
Forty percent of the capsules failed to pass the first test, but all ten eventually passed when subjected to the USP testing conditions.
