Evaluation of vitamins diversity produced by probiotics in the microbiome and introduction of selected species

Vitamins are important micronutrients and are often precursors of enzymes that living cells need to perform biochemical reactions. Because humans cannot biosynthesize most vitamins, therefore, they must be obtained exogenously. Although a variety of vitamins are found in most foods, many people's vitamin deficiencies still occur mainly due to malnutrition as a result of inadequate food consumption or poor eating habits. In this review article, the potential of lactic acid (LAB) and bifidobacteria probiotics is investigated as an inexpensive and terminating solution to this problem. Probiotics can produce important vitamins in the microbiome, including vitamin A, vitamin D, vitamin K, vitamin B12, and so on. Therefore, increasing the ratio of probiotics in the microbiome is one of the important ways to eliminate vitamin deficiency. The gut microbiome plays an important role in health and disease as personalized medicine. The results also showed that Lactobacillus reuteri and L. rhamnosus could be the best choices for producing a set of vitamins needed by a person in terms of diversity by producing B‐group vitamins, vitamin K2 and vitamin D.
