Gut microbiota and calcium balance

Area of Science:

• Microbiology
• Human Physiology
• Nutritional Science

Background:

• The human body hosts a vast community of microorganisms, collectively known as the microbiome, with the gut microbiome being the largest and most influential.
• Disruptions in calcium homeostasis are implicated in various diseases, including chronic renal insufficiency with secondary hyperparathyroidism and liver conditions like cirrhosis.
• Emerging evidence suggests a link between calcium dysregulation and lipid metabolism via specific cellular pathways.

Purpose of the Study:

• To review the multifaceted roles of the gut microbiome in regulating calcium balance within the human body.
• To explore the influence of key gut-derived factors, including short-chain fatty acids, on calcium homeostasis.
• To examine the interplay between the gut microbiota, immune factors, vitamin D, and estrogen in maintaining calcium equilibrium.

Main Methods:

• Literature review of studies investigating the gut microbiome and calcium metabolism.
• Analysis of research on probiotics and their impact on calcium absorption.
• Synthesis of findings on short-chain fatty acids, estrogen, immune factors, and vitamin D in relation to calcium balance.

Main Results:

• Probiotics have demonstrated efficacy in improving calcium absorption.
• Gut microbiota metabolites, such as short-chain fatty acids, play a significant role in modulating calcium levels.
• Factors like estrogen, immune mediators, and vitamin D interact with the gut environment to influence calcium balance.

Conclusions:

• The gut microbiome is a critical determinant of calcium homeostasis.
• Targeting the gut microbiota and its metabolites presents a promising therapeutic avenue for managing calcium-related disorders.
• Further research into the complex interactions between the gut flora and host factors is warranted for optimizing calcium balance.
