Although probiotics are not new, 5 new commercially available products have been launched onto the South African market in the last 2 years. Evaluations of products in the USA and Europe shown poor correlation between label claims and actual contents. We undertook an evaluation of 9 products currently available on the shelves in South Africa. ⋯ This evaluation confirms that the contents of several probiotics available in South Africa do not correspond to the label claims. This is of concern as clinical efficacy is dependent on strain specificity and organism numbers. Current regulatory requirements do not address this discrepancy. As such, we recommend that commercially available probiotic products be screened annually and the results of such quality control measures be made available to the Medicines Control Council (MCC).
