The 3 ways your gut controls your hormones
Your gut is running your hormones. Here's what to do about it.

If your hormones feel out of control (think: moody, bloated, exhausted, irregular) the conversation usually starts in the wrong place. It starts with your cycle, your stress, your age, but rarely where it should: your gut.



THE 3 WAYS YOUR GUT CONTROLS YOUR HORMONES


Your gut metabolizes estrogen. A collection of gut bacteria called the estrobolome regulates circulating estrogen. When your microbiome is disrupted, estrogen metabolism breaks down, driving PMS, mood instability, and perimenopausal symptoms.

It produces your mood hormones. Roughly 90% of your body's serotonin is made in the gut. Low gut diversity means low serotonin and the mood swings, poor sleep, and exhaustion that come with it.

It drives inflammation that disrupts everything. A compromised gut lining allows inflammatory compounds into the bloodstream, impairing thyroid function, worsening insulin resistance, and amplifying every hormonal symptom. You can't out-supplement a chronically inflamed gut.



WHERE SUPER CORE COMES IN

Kroma Super Core Colostrum supplement facts and features on a brown background

Most gut supplements aren't built for women's biology. Super Core is.

It's dairy-free and human-optimized, combining three precision-fermented ingredients: effera® Lactoferrin to support gut barrier integrity and immune defense; ImmunoLin® IgG to neutralize inflammatory compounds before they enter the bloodstream; and GlyCare 2'FL HMO (the same prebiotic found in human breast milk) to feed the beneficial bacteria your hormonal balance depends on.

One scoop. No dairy. No bloat. No compromise.

Address the gut to change your hormonal picture.

P.S. Super Core is the most direct path to rebuilding your gut lining from the inside — and feeling the difference in your hormones. → SHOP NOW

Frequently Asked Questions

Is the colostrum dairy-free?

Yes — Super Core Colostrum is non-dairy, making it accessible for those avoiding traditional dairy products. Check the individual product page for full ingredient and allergen details.

Are all your ingredients organic?

We source organic whenever it’s available, but not every ingredient can be certified organic. For example, collagen isn’t available in organic form, and Chocho—a powerful plant protein grown sustainably at 10,000 feet in Ecuador—hasn’t yet been certified despite its pristine farming practices. Our standard is always the same: we source only the cleanest, most nutrient-dense, sustainable ingredients on the planet.

What makes it different from cow colostrum?

Super Core is 15x more bioavailable, cleaner, and more sustainable — no dairy required.

What is Super Core made of?

Super Core is made from : 

  • effera® - (Lactoferrin) High purity recombinant human milk protein made through precision fermentation. 
  • Immunolin (IgG) - ImmunoLin® is the branded ingredient serum-derived bovine immunoglobulin/protein isolate (SBI). 
  • Glycare (HMO 2FL) - GlyCare 2'FL is a commercially available human milk oligosaccharide (HMO) produced through precision fermentation
  • Allulose and Reb-M for sweeteners.
  • Vanilla Flavor 

How does gut health affect hormone balance?

Your gut helps regulate estrogen, serotonin, and inflammation levels. When the gut microbiome is disrupted, it can contribute to PMS, bloating, mood swings, fatigue, and other hormone-related symptoms.

What is the estrobolome and why is it important?

The estrobolome is a group of gut bacteria that helps metabolize estrogen. Poor gut health may disrupt this process, potentially leading to estrogen imbalance and worsening hormonal symptoms.

Can poor gut health cause mood swings and low energy?

Yes. Around 90% of the body’s serotonin is produced in the gut. Low gut diversity and inflammation may affect mood, sleep quality, stress response, and overall energy levels.

Why does inflammation in the gut affect hormones?

A weakened gut lining can allow inflammatory compounds into the bloodstream. This may interfere with thyroid function, insulin sensitivity, and hormone regulation throughout the body.

How does Super Core support gut and hormone health?

Super Core combines lactoferrin, IgG, and HMO prebiotics to help support gut barrier integrity, beneficial bacteria growth, and immune balance — all of which play a role in maintaining healthy hormone function.
