What to Know About Colostrum Supplements

7. Who Shouldn’t Take Colostrum?

Colostrum supplements aren’t appropriate for everyone. People with a true dairy allergy — not just lactose intolerance — should avoid them entirely, as reactions can be severe. Even those with milder sensitivities may experience digestive symptoms depending on how the product is processed.

There’s also limited safety data for people with autoimmune conditions, suppressed immunity, or chronic illness. Because colostrum contains compounds that affect immune activity, it could interfere with medications or make some conditions harder to manage.

Most colostrum products haven’t been tested for use in children, during pregnancy, or while breastfeeding. That makes it especially important to check with a healthcare provider before starting.

Additionally, colostrum is not vegan, and may not be compatible with some religious or ethical dietary preferences.
