Doctor Life / 01

Colostrum

Made for your daily routine.

The formula uses proprietary liposomal encapsulation designed to protect sensitive colostrum components from digestive conditions and support their delivery to the small intestine. This describes the formulation’s intended function, not proof that all bioactive peptides remain intact or are absorbed.

The standard serving is 2 capsules daily between meals, increasing to 4 during periods of greater demand as directed. Each 120-capsule bottle provides 60 or 30 days of use, respectively.

Colostrum

Why is colostrum of interest?

Colostrum is the first milk produced after birth and contains bioactive proteins and peptides. Research examines mucosal immune responses and intestinal barrier function, including in active adults. Capsules provide a measured serving without mixing powder.

Colostrum

What does research say about Colostrum?

A meta-analysis in regularly exercising adults reported fewer days and episodes of upper respiratory symptoms with bovine colostrum supplementation. Other clinical studies and reviews examined intestinal permeability, including during intense exercise. The studies used specific preparations and doses, not this finished liposomal product. Their findings do not establish infection prevention or equivalent results for the capsule formula.

Science & sources

Understand the formula.

Colostrum is a naturally complex source of bioactive proteins and peptides. Studies in active people explore its potential in immune support, demanding periods, and intestinal barrier function.

These publications concern the studied ingredients or formulas. They do not all evaluate the finished Doctor Life product, and research results do not guarantee individual outcomes.

01Bovine colostrum supplementation and upper respiratory symptoms during exercise training: a systematic review and meta-analysis of randomised controlled trials

Arwel W. Jones, Daniel S. March, Ffion Curtis, Christopher Bridle

BMC Sports Science, Medicine and Rehabilitation (2016), 8, 21. DOI: 10.1186/s13102-016-0047-8; PMID: 27462401.

A meta-analysis of five randomized studies included 152 adults who exercised regularly. Over 8–12 weeks, colostrum supplementation was associated with fewer days with upper respiratory symptoms and fewer symptom episodes. The findings explore its role in active routines and intensive training.

02Oral Supplementation with Bovine Colostrum Decreases Intestinal Permeability and Stool Concentrations of Zonulin in Athletes

Maciej Hałasa, Dominika Maciejewska, Magdalena Baśkiewicz-Hałasa, Bogusław Machaliński, Krzysztof Safranow, Ewa Stachowska

Nutrients (2017), 9(4), 370. DOI: 10.3390/nu9040370; PMID: 28397754.

A double-blind study in athletes examined colostrum's effects on intestinal permeability and zonulin levels. Supplementation was associated with favorable changes in intestinal barrier measures. This is relevant to research on intensive exercise and digestive stress.

FAQ / Colostrum

Good questions. Clear answers.

Talk to us ↗

Why use liposomal encapsulation?

The technology is designed to protect sensitive colostrum proteins and peptides from digestive conditions and support delivery to the small intestine. It does not by itself establish how much reaches the intestine intact or is absorbed in humans.

When should I take two versus four capsules?

The standard serving is 2 capsules daily between meals. The directions allow 4 capsules daily during periods of greater demand. Do not exceed the stated maximum.

Is Colostrum suitable for vegans and vegetarians?

No. Colostrum comes from cows, and the capsule shell contains gelatin. The product is not classified as vegan or vegetarian.

Is it relevant to active people?

Colostrum research includes regularly exercising adults, with studies of upper respiratory symptoms and intestinal barrier measures. These findings provide context, but do not establish the effects of this finished product in athletes.

How long does the 120-capsule bottle last?

It lasts 60 days at the standard serving of 2 capsules daily or 30 days at 4 capsules daily.

Why take colostrum between meals?

That is the schedule specified for this formula: 2 capsules daily between meals, or 4 during periods of greater demand. Choose a consistent time between meals to support regular use.

Can I take Colostrum with medication?

If you take regular medication, have specific dietary needs, or are unsure about combining products, consult your doctor or pharmacist before use.
