Thaena

The Thaena Donor Program

Our donors are not suppliers.

They are partners in a regenerative healing ecosystem — individuals whose exceptional microbial biodiversity helps advance science, restore depleted microbiomes, and redefine what thriving human health can look like.

This is Humans Healing Humans, at scale.

We Built Our Donor Program From Scratch

Because regenerative health starts at the source.

Unlike conventional donation models, we:

  • Do not outsource donor screening
  • Do not rely on minimum-viability health definitions
  • Do not ignore health and wellness habits like diet and lifestyle

Instead, we curate a living reference for what thriving human biodiversity looks like in practice — and hold every downstream process to that same standard.

This allows us to set a higher bar for safety, consistency, and postbiotic diversity.

Most stool banks just screen for disease. We look for patterns of health across the whole system.

At Thaena, health is measured by resilience, regulation, and long-term balance — not just lack of disease. We look for individuals whose bodies demonstrate:

Stable, well-regulated digestion
Low baseline inflammation
Robust immune and metabolic signaling
Long-term physiological consistency, not short-term optimization

This level of biological coherence is rare. That rarity is exactly why it matters.

Who Qualifies

Eligibility for the Thaena Donor Program reflects whole-body health across time, not isolated metrics.

Thaena's Donor Program is constantly being improved upon by functional medicine professionals. Currently, candidates must meet strict criteria, including:

Age 18-45
Healthy, stable BMI
Vaginal birth and breastfed in infancy
Consistent, high-quality daily bowel movements
Long-term whole-food dietary patterns
Regular exercise and mindfulness-based practices
No history of chronic GI, autoimmune, metabolic, or inflammatory disease
No history of mental health conditions
Minimal antibiotics exposure over their lifetime
No prescription medications
No tobacco or recreational drug use

Final eligibility is determined through comprehensive clinical screening and advanced laboratory testing.

Fewer than 1% of applicants qualify.

Our standards are intentionally strict to ensure consistency, safety, and exceptional microbiome quality.

How the Selection Process Works

Every potential donor goes through a thoughtful, medically supervised process designed to protect both donors and customers.

1

Initial Application Review

A brief survey to ensure basic eligibility

2

Health & Lifestyle Questionnaires

Detailed history, bowel movement tracking, and food diary

3

Physician Interview

One-on-one review with our clinical team

4

Clinical Screening & Lab Testing

Blood, stool, and urine analysis

5

Ongoing Monitoring

Continued participation depends on sustained health over time, regular check ins, and follow up lab screenings

At Thaena, donor health is not a one-time decision — it's an ongoing relationship.

Because the microbiome responds to sleep, stress, diet, environment, and major life events, we monitor donors continuously and pause collection whenever balance may be temporarily disrupted.

"Everything affects the microbiome. When one of our donors experienced a significant loss in their family, we paused collection until their system returned to balance."

Dr. Andrea McBeth, CEO

This approach protects donors, preserves signal integrity, and reflects how seriously we take our responsibility to both sides of the healing relationship.

From Donor to Postbiotic Signal

Donor screening is only the first step in Thaena's broader safety and quality process.

From there, every batch undergoes:

1

Controlled collection

2

Patented sterilization for safety

3

Freeze-drying to preserve postbiotic signals

4

Third-party batch testing for safety, purity, and consistency
