However, more recently, they have been incorporated into a non-dairy product that has gained popularity, known as Kombucha. Probiotics have been integrated into products or food supplements, highlighting the incorporation in fermented dairy products. They have also been reported in the literature as a way to prevent or even treat some diseases, such as cancer, cardiovascular diseases, diabetes, and allergic reactions. Probiotics are defined as a group of microorganisms (such as Bifidobacterium, Lactobacillus, Zygosaccharomyces, and others) that, when consumed in adequate amounts, provide some health benefits to the host organism, like boosting the immune system and balancing the intestinal microbiota. Nowadays, particular emphasis is being placed on including probiotics or prebiotics in the diet. Some functional foods examples include probiotics, prebiotics, dietary supplements, vitamins, and antioxidants. Functional foods are products that have the necessary nutrients for human survival, providing some health benefits related to physical and mental health. Furthermore, functional food research, i.e., a rising study field aiming to explore natural active components that provide health benefits beyond essential nutrition, has advanced drastically to prevent diseases and promote wellbeing and people’s quality of life. For example, the study of microbial protein has increased prominently and includes algae, yeast, bacteria, and fungi. There is a growing interest in food technologies to develop functional and bioactive ingredients for health promotion and guarantee food safety. It is expected that circular food-related technology, based on the 4R strategies of reducing, reusing, recycling, and recovering, will positively affect several SDGs. On the other hand, an unhealthy diet is responsible for micronutrient deficiencies or dietary excesses, and it contributes to creating and increasing the incidence of diet-related diseases or conditions, such as obesity, cardiovascular diseases, diabetes, cancer, and other pathologies. Another significant aspect of this reconfiguration process is to adopt a healthier diet based on more beneficial products, which is fundamental to reduce mortality and morbidity and improve quality of life. Reconfiguring food systems, and introducing new policies in line with the Sustainable Development Goals (SDG), is extremely important to deliver healthy and sustainable diets and new products to everyone in order improve their lives and the planet. For this, nowadays, there is a growing awareness of sustainable policies to promote the quality of life of the population and active and healthy aging. In the light of society’s evolution and modernization, there is the aspiration and idealization of a healthier community. Thus, this study focuses on a pertinent theme and alerts to the need for legislation for these products, to draw attention to the inexistent legislative control and the consequent need for regulatory guidelines for better and safer production and consumption. Likewise, it is important to spread awareness among the population of these products and their impacts on people’s health. Thus, it is essential to highlight the potential value of this product and invest in its development and marketing.

Key findings and conclusions: The lack of regulation and the low level of literacy about this product can limit its development, marketing, and impact on health.

Aim: The study intends to draw attention to the need for regulatory guidelines and the potential of this product in the market and peoples’ health. However, it needs regulatory guidelines to control the production and guarantee the product’s efficacy and safety. This natural product has been developed to improve or promote physical and mental health. Legislative efforts about these products remain confusing and without global harmonization. Background: Kombucha is an increasingly consumed product classified as a nutraceutical.
