See If You Qualify

This is a 20-week randomized, double-blind, placebo-controlled study of a daily bovine colostrum powder, run entirely from home through the Alethios platform. Colostrum has become one of the most talked-about supplements for gut and immune health. This study is designed to add to the growing body of research by generating controlled, real-world data on its impact in healthy adults.

About This Study

At-Home Remote Study
Everything is completed remotely through the Alethios app: a one-tap daily dose log, a short weekly check-in, and six longer surveys across 20 weeks.
At-Home Blood and Gut Testing
You collect two finger-prick blood samples and two stool samples. Each blood sample kit ships with lancets, a collection card, an alcohol wipe, a bandage, and a prepaid return envelope.
Compensation Available
Participants who meet study requirements will receive up to $100 in Amazon gift cards: $25 after Week 4, $25 after Week 12 and $50 at the end of the study. Each stage is released at 75% task completion or above and is emailed within 14 days.
Data Available at Study Conclusion
When the study ends, you'll get copies of your bloodwork, microbiome tests and a skin health report.

What's Involved

You take your daily serving for 16 weeks and log it with one tap each evening, complete a short check-in on the same day each week, and fill in six longer surveys at Weeks 2, 4, 8, 12, 16 and 20 covering digestive comfort, bowel habits, reflux, immune resilience, energy and sleep. You collect a fasted finger-prick blood sample and a stool sample at home in Week 1 and Week 16, all returned in prepaid envelopes.

Check Eligibility and Enroll

Complete a 21-question screening questionnaire, about 7 minutes, to confirm you qualify. If eligible, you will be emailed a link to set up your Alethios account, review the study details and sign your electronic consent form through the platform.

Complete Onboarding and Day 1 Blood and Stool Collections

Complete your Onboarding to start your study including your baseline questionnaires on digestive comfort, immune resilience, energy and sleep through the Alethios platform. Your supplement tub and three kits then ship, and once you confirm receipt of all three in the app your schedule begins the next day with a fasted finger-prick blood collection and a stool collection on Day 1.

Take Your Daily Serving and Complete Weekly and Periodic Surveys

Take one scoop as shown on your tub label once a day for 16 weeks and log it with one tap each evening, plus a short check-in on the same day every week for the full 20 weeks. Longer surveys on gut and immune health run at Weeks 2, 4, 8, 12, 16 and 20, take about 20 minutes and are announced two days in advance.

Complete Final Assessment and Receive Compensation

After a four-week washout with no supplement, complete your final surveys. Adherent participants receive up to $100 in Amazon gift cards: $25 after Week 4, $25 after Week 12 and $50 at the end of the study.

What's Being Studied?

Bovine colostrum is widely used for digestive comfort and immune support, and early work points to effects on gut barrier function and immune signalling. What is far less clear is whether a daily serving changes how people actually feel over months rather than weeks, and how that compares to a placebo. This study tracks self-reported digestive comfort and immune resilience across 16 weeks of daily use plus a four-week washout, alongside at-home metabolic panels, gut microbiome samples, and passively collected sleep, step and heart rate variability data.
