The diversity of the microbiome has profound implications for metabolic health. The micro-organisms that we host in our gastrointestinal tract maintain our gut integrity, break down complex carbohydrates to improve energy extraction from food, produce vitamins and minerals, aid in digestion and absorption, ferment dietary fibers and protect us against pathogens. Maintaining a delicate balance in the diversity of the host-microbiome relationship is crucial for disease prevention and healthy aging. 

Studies on the microbiome are emerging as a new and exciting frontier of science. However, how the microbiome interacts with the endocrine system to modulate metabolic health is still one of the less explored avenues in microbiome research. This blog aims to shed light on the intertwined roles of gut microbiota and estrogen on metabolic health for women as they transition into menopause.

Two months ago, a large team of scientists working on multiple continents published a research study that came to startling conclusions about breast cancer and natural progesterone. The team determined that unlike synthetic progestins, which increase breast cancer risks, natural progesterone has the potential to slow the growth of many breast cancer tumors or even shrink them.
