Who Should Take Probiotics?

Probiotics for Healthy Adults

Probiotics, which are live microorganisms that confer health benefits when consumed in adequate amounts, have been shown to positively impact several health outcomes in healthy adults. Research indicates that probiotics can lead to transient improvements in gut microbiota, enhance immune system responses, improve stool consistency and bowel movements, and increase vaginal lactobacilli concentration in women. However, there is insufficient evidence to support their role in improving blood lipid profiles in healthy adults.

Probiotics for Older Adults

In older adults, probiotics have been found to improve cognitive function and mood. A study involving community-dwelling older adults demonstrated that probiotics could reduce the relative abundance of inflammation-causing gut bacteria, improve mental flexibility, and alleviate stress. Additionally, probiotics significantly increased serum levels of brain-derived neurotrophic factor (BDNF), which is associated with improved brain function.

Probiotics for Gastrointestinal Disorders

Probiotics are commonly used to manage various gastrointestinal (GI) disorders. They have been shown to be beneficial in treating conditions such as diarrhea, inflammatory bowel diseases (IBD), and liver diseases by modifying the gut microbiota. However, the effectiveness of probiotics can vary depending on the specific GI condition and the probiotic strain used .

Probiotics for Patients with Specific Health Conditions

Probiotics have been found useful in the treatment and prevention of several infections and disorders, including gastrointestinal diseases, pneumonia, urogenital infections, depression, anxiety, cancer metastasis, and obesity. However, their use should be approached with caution in high-risk groups, such as seriously ill and hospitalized patients, as there have been documented cases of probiotics causing opportunistic infections like sepsis and endocarditis in these populations .

Safety and Efficacy Concerns

While probiotics are generally considered safe for the general population, their efficacy and safety can vary. Some studies have reported adverse effects, particularly in vulnerable groups such as neonates, individuals with malignancies, and those with compromised immune systems. Additionally, the unregulated use of probiotics carries the risk of antibiotic resistance transfer to gut pathogens.

Conclusion

Probiotics can offer health benefits to various groups, including healthy adults, older adults, and individuals with specific health conditions, particularly gastrointestinal disorders. However, their use should be tailored to the individual's health status and specific needs. High-risk groups should use probiotics with caution due to potential adverse effects. Further research is needed to fully understand the long-term benefits and risks associated with probiotic supplementation.
