Why Use Grass-Fed Colostrum

Supports immune resilience, gut integrity, and muscle recovery with a clinically effective 20g dose of bioactive-rich, grass-fed bovine colostrum.

Optimize Immune Function

Help balance immune responses during intense exercise and reduce training-related inflammation.

Support Gut Health

Strengthen the gut barrier and reduce intestinal permeability (leaky gut) especially in high-stress training environments.

Enhance Muscle Recovery

Packed with growth factors that promote muscle protein synthesis, improve body composition, and support recovery from strenuous workouts.

Clinically-Dosed for Performance

At 20 grams per serving, this is one of the highest-potency colostrum supplements available—dosed in line with scientific studies to drive real results in active individuals.

Key Ingredients

Our formulas are made with clean, natural ingredients, with clinically-validated dosages to support health and performance.

Grass-Fed Bovine Colostrum

20 g
Grass-fed bovine colostrum is a bioactive-rich, immune-priming “first” milk produced by cows in the immediate postpartum period.

Grass-Fed Bovine Colostrum

20 g

Transparent Labs Grass-Fed Colostrum contains 100% pure bovine colostrum with a minimum 20% Immunoglobulin G (IgG) content, sourced exclusively from grass-fed cows. Bovine colostrum is the “first milk” cows produce and it’s incredibly  rich in biologically active compounds—immunoglobulins, growth factors like IGF-I, lactoferrin, and antimicrobial peptides—known to support immune modulation, gut barrier integrity, and muscle regeneration.

Clinical research shows that supplementation with 20g/day is the effective dosage required to provide benefits specific to digestive health and recovery—particulary in active individuals. [2] Bovine colostrum significantly reduces zonulin levels (a marker of gut permeability), enhances mucosal immunity, and supports the maintenance of lean muscle mass in athletes. [3, 4, 5, 6, 7]

Transparent Labs delivers this evidence-based dose in every serving—because when it comes to performance, underdosing isn’t an option.

Amazing Benefits

So I have tried Amara and it didn’t really seem to do anything at all except drain my bank account!! I decided to try this because its a higher dose and comparable price point. I have been on it for almost a month and at my age and having both my shoulders done, pain free was never something I thought I would ever get to enjoy again:(. Well I have got to say this is the reason Im able to finally do good workouts and Im overwhelmed at how good my shoulders and knees feel!! Even with arthritis in my left shoulder and ac joint. I have literally no pain at all!!! I have told everyone that I know about this because this is a much more enjoyable life than before!!! Please try this and hopefully it will do the same thing for you!! TL is a great quality supplement company!!

Only a few days in but love the stuff!

Tastes better than any protein powder I've ever taken and have already noticed gut health benefits. No bloated feeling after taking like most other whey supplements. I'll update again after a few weeks of taking this but so far so good.
