Objective:

To analyze the composition of formulations of probiotics sold in establishments in the State of Tabasco or that can be purchased online.

Materials and methods:

A descriptive study in which formulations of probiotics sold in 21 establishments in the city of Villahermosa were identified and compared with 30 probiotic supplements sold online. Product information was organized in a database and analyzed according to the dosage form, probiotic genera, species/subspecies contained and their classification as probiotics or synbiotics and as drugs or supplements.

Results:

Thirty-one local products and 30 online products formulated with probiotics in 6 different dosage forms were analyzed. Only five local products and no online products are certified by COFEPRIS as drugs. Forty-eight percent of the formulations are monostrain and the rest are multistrain. Seventy-two percent of the formulations are probiotics and the rest are synbiotics. Among the 61 products analyzed, 46 species belonging to 13 different genera were identified, and 39% were common to local and online products. Many of products contain species of the Lactobacillus and Bifidobacterium genera. The genus Bacillus was the only genus that was never combined with other genera in the formulations analyzed in this study.

Conclusions:

The population of the state of Tabasco can find at least 31 formulations of probiotics in local establishments. The variety increases if we consider the dietary supplements available for sale online. Multistrain supplements are particularly abundant in online retailers. The products certified by COFEPRIS ensure that the benefits of the formulation are supported by clinical trials in humans and are manufactured following good manufacturing practices.
