Understanding the Human Microbiome Project:

A New Perspective on Gut Health



Introduction to the Human Microbiome Project (HMP)

The Human Microbiome Project, a monumental study, has revolutionized our understanding of the human microbiome over the past three years, providing insights far beyond what was known in the previous five decades. This project aimed to map the vast and intricate ecosystem of microbes that inhabit the human body, revealing critical findings about our microbiome’s size, complexity, and crucial role in our health.

Key Discoveries of the HMP

Microbiome and Human Cells

The human microbiome outnumbers human body cells by a ratio of 10 to 1, highlighting its significant presence.

Genetic Contribution

Microbes contribute more genes essential for human survival than our own human genes do.

Microbiome Dynamics

Our microbiome composition can change over time, influenced by factors such as disease states and medication use.

Diversity for Gut Health

One of the HMP’s most significant findings is the importance of microbial diversity in maintaining a healthy gut. Increasing the variety of microbial species in the gut is now recommended for optimal gut health.

Enhancing Microbiome Diversity: Prebiotics and Probiotics

To support microbiome diversity, the integration of specific prebiotics and probiotics into your diet is advised:


Partially hydrolyzed guar gum (PHGG) is highlighted as an effective prebiotic that selectively nourishes beneficial bacteria, promoting a diverse and healthy microbiome.


Bacillus Spore probiotics are preferred over dairy-based strains for their natural occurrence and compatibility with the human gut. These “human strain” probiotics are encased in an endospore, ensuring they survive stomach acid and bile to deliver health benefits effectively.

Perfect Pass Vitamins' Approach

Leveraging insights from the HMP, Perfect Pass Vitamins recommends a combination of PHGG soluble fiber prebiotic and human strain bacillus spore probiotic to foster optimal digestive health and function.

What should you take to increase your Microbiome Diversity?

Again, this is very different from what we understood even a few years ago.

Here are the important points when choosing your prebiotic and probiotic:

  • When choosing a prebiotic to increase the diversity of your microorganisms, you want to make sure it is partially hydrolyzed guar gum (PHGG), which is the most effective soluble fiber that selectively “fertilizes” and feeds the good bacteria of your microbiome.
  • Bacillus Spore probiotics, as opposed to dairy-based strains, are found in nature and are identical to those found in the gut. They are referred to as human strain. The endospore outer casing ensures a 100% survival rate through stomach acid and bile. This way you get all the health benefits without losing any potency. You only need 1 spore probiotic capsule per day. They are extremely stable so there is no need for refrigeration like dozens of probiotics you may have been taking to date.
