A New Study Highlights Probiotics' Potential in Addressing Folate Deficiency

    Folate deficiency remains a significant global health problem, prompting researchers to explore natural alternatives beyond traditional supplements. This recent survey highlights the potential of probiotics to increase folate levels and reduce health risks associated with folate deficiency.

     

    According to estimates of nutrient intake from food (excluding fortification and supplements), more than 4 billion people worldwide are deficient in folate, accounting for over 54% of the global population.

     

    Can Probiotics Help Bridge the Folate Gap?

     

    This systematic review, conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, compiles findings from 27 studies out of more than 2,700 scientific articles, highlighting the potential of probiotics as a natural source of folate.

    The analysis reveals that administering single-, double-, and multi-strain probiotic formulations can produce strain-specific effects on folate levels, homocysteine reduction, and hematological markers associated with anemia.

    Although effects vary by strain, evidence suggests that probiotic microorganisms can produce highly bioavailable folate and enhance the absorption of essential micronutrients, offering significant benefits in addressing nutritional deficiencies.

     

    Probiotics: A Promising Natural Approach to Folate Fortification

     

    Folate deficiency remains a significant global health issue, affecting over 40% of people in many regions. While mandatory folate fortification programs in food have been implemented to address this issue, research on natural approaches continues to expand.

     

    Emerging research highlights probiotics as a promising solution because these beneficial bacteria can produce folate directly in the colon. This naturally produced folate is more easily absorbed than synthetic forms, providing specific benefits for individuals with genetic variations that affect folate metabolism.

     

    The findings suggest the possibility of creating functional foods fortified with folate-producing probiotics. Such products could support existing fortification initiatives, naturally increase folate intake, and help prevent related health issues, including anemia and elevated homocysteine levels.

    Deep Dive Into Folate

    Folate, also known as vitamin B9 or folic acid, is a water-soluble essential nutrient that plays a crucial role in many physiological processes in the body, such as healthy cell growth, DNA synthesis, and red blood cell formation.
