The best colostrum to buy is true colostrum, harvested from the first milking within 6-8 hours following birth. Researchers at Cornell University confirm that colostrum collected during this time frame retains the highest levels of crucial growth and immune factors.
Why Timing Matters:
- First 6-8 Hours: True colostrum must be collected within 6-8 hours after birth. This early harvest ensures the product is rich in immunoglobulins, growth factors, and other essential nutrients.
- Changes After 8 Hours: After the initial 6-8 hours, the lactose content increases significantly, and the fat content changes, leading to a loss of vital growth and immune factors.
Common Market Practices:
- Many bovine colostrum powders available today are collected up to 72 hours after the calf’s birth. For example, some international imported brands harvest colostrum within 24 to 48 hours resulting in a product closer to “transitional milk” than true first-milking colostrum.
Lack of Regulation:
- Unfortunately, there is no legal definition for first-milking colostrum, and government regulations do not require labels to disclose the exact timing of colostrum collection. Non-disclosure makes it challenging for consumers to identify true colostrum products.
Consumer Advice:
- Ask your preferred brand of choice about the harvesting time frame to ensure you purchase true colostrum. Confirm whether their colostrum was collected within 6-8 hours following birth.
By choosing IMUMI first-milking colostrum harvested within the first 4-6 hours with a certified (minimum) 40% Immunoglobulin content, you can be confident in our product’s quality and effectiveness. Always verify the details with the distributor to ensure you get the best colostrum for maximum health benefits.
First-Milking Colostrum (6-8 hours):
Nutrient Content:
- Immunoglobulins: First-milking colostrum is exceptionally rich in immunoglobulins (IgG, IgA, IgM), which are critical for passive immunity.
- Growth Factors: It contains high levels of growth factors such as IGF-1 and TGF-beta, which aid in the development and healing of tissues.
- Vitamins and Minerals: This colostrum is dense with essential vitamins (A, E, B12) and minerals (zinc, magnesium) necessary for overall health.
- Enzymes and Hormones: Enzymes and hormones in first-milking colostrum are vital in digestive and metabolic processes.
- Lower Lactose Content: The lactose content in first-milking colostrum is lower, which is beneficial as it is easier on the digestive system.
Transitional Milk (8+ hours):
Nutrient Content:
- Reduced Immunoglobulins: The concentration of immunoglobulins decreases significantly after the first 6-8 hours, making it less potent in providing passive immunity.
- Altered Fat and Lactose Content: Lactose levels rise, and fat composition changes, making it more similar to regular milk.
- Diminished Growth Factors: The levels of growth factors decrease, reducing their beneficial effects on tissue development and healing.
- Vitamins and Minerals: While still present, the concentration of vitamins and minerals starts to shift towards those found in mature milk.
