Gluten Free Dietary Supplement Ultra Tested - Tested for More Than 950 Contaminants! Heavy Metals Bacteria Yeast Mold Pesticides & More... Kirkman offers Colostrum Gold Liquid in a raspberry flavored version. It is sweetened with sucralose to cover up the strong taste and odor of natural colostrum. Our Colostrum Gold may be one of the only casein and gluten free colostrum products available in the United States. Colostrum has been called "nature's first food" because female mammals produce colostrum just before they give birth. The yellow fluid is excreted in the milk for approximately three days following birth. After this, colostrum is no longer produced in the mammal. Colostrum supplies immune and growth factors and a perfect combination of vitamins and minerals to the newborn. Colostrum helps support the immune system and provides growth factors to stimulate growth of muscle, skin, cartilage, nerve and bone tissue. Kirkman's Colostrum Gold has been perfected by quality control methods to yield a pure and potent product. Colostrum is obtained from hormone-, pesticide- and antibiotic-free cows only during the first 24 hours after they give birth. A multiple filtration process makes Colostrum Gold casein free at detectable laboratory levels. Every batch is tested for casein by an independent laboratory before it is shipped to Kirkman. Kirkman's Colostrum Gold Liquid is: sourced from USDA and FDA inspected dairies collected within 12 hours of production free of synthetic hormones, pesticides and antibiotics processed using minimal heat to ensure the stability of its nutritional factors unadulterated to maintain its natural wholeness and nutrition formulated and purified to be gluten and casein free.
