Colostrum VS. Milk: What’s the Difference?

colostrum vs. milk

Colostrum and milk are closely related compounds that all female mammals produce to breastfeed their offspring. But while they’re related, they’re not the same and therefore have different uses in health. So, what’s the difference when looking at colostrum vs. milk? Read on to find out.

What is Colostrum?

Colostrum is often referred to as “first milk,” and is produced by all mammals during pregnancy. It is a thick, yellowish form of milk, typically available in the days immediately after birth.

Colostrum is higher in both fat and protein than regular milk. It is an impressively concentrated substance, packed with important nutrients and antibodies that newborns need for protection. Colostrum is essential in strengthening both the immune and digestive systems of the baby. It is the first immune system defense they receive after birth.

The most common form of commercial colostrum is produced by cows, but other colostrum supplements exist.

What is Milk?

Colostrum’s more well-known cousin, milk, is also produced by all mammals, but after colostrum production has stopped. Unlike colostrum, milk can be produced for months or years after birth.

Much like colostrum, milk produced by cows is the most popular form of commercial milk consumed by humans. It is thinner and whiter than colostrum but is also rich in macro and micronutrients such as protein, calcium, potassium, iodine, phosphorus, and vitamins B2 and B12.

Colostrum’s Uses in Health

While both colostrum and milk have been consumed for thousands of years (whether knowingly or not), colostrum is experiencing a peak in public interest due to its health benefits and uses. This includes effective diarrhea relief, in both children and adults. Check out our recent blog article to learn more about the health benefits of colostrum.

    I recently benefited from DiaresQ on a trip to South Africa. However; my major ongoing problem is constipation: Is there anything in the works to treat this end of the spectrum of gut imbalance? Your product is amazing….Thank you!

  • I have heard so much about colostrum being powerful and all but never really experienced drinking it but i believe it would be something worth trying.
