Colostrum vs Glycine
Expensive immune supplement vs cheap amino acid
The Verdict
The short answer: Glycine is a better value for most people. Colostrum is for specific gut/immune concerns.
Choose colostrum if: You have gut issues, frequent illness, or specific immune support needs.
Choose glycine if: You want better sleep, general health support, or best value supplementation.
The science says: Glycine has broad benefits at very low cost. Colostrum has more targeted benefits at much higher cost. For general health, glycine wins on value.

- Supports gut barrier function
- Contains bioactive compounds for immunity
Glycine
Mechanisms
- Lowers core body temperature for sleep
- Inhibitory neurotransmitter
- Required for collagen synthesis
- Precursor to glutathione
- Supports methylation
Key Research

Frequently Asked Questions
Is colostrum worth 4-6x the price of glycine?
Only if you have specific gut or immune issues. For general health and sleep, glycine provides better value. Most people should start with glycine.
Can I take both?
Yes, no interaction. Glycine at night for sleep; colostrum in morning for gut/immune. But for most people, glycine alone is sufficient.
What about dairy allergy with colostrum?
Colostrum contains dairy proteins. If you have dairy allergy or sensitivity, avoid colostrum. Glycine has no allergen concerns.
Which is better for athletes?
Glycine for sleep and recovery support. Colostrum may help prevent illness during heavy training or travel. Glycine is the better foundational choice.
How much glycine for sleep?
3g before bed is the standard dose from studies. Some use up to 5g. It's very safe - no serious side effects reported even at higher doses.
