Clinical studies show the efficacy of Colostrum

Colostrum is one of the most highly researched ingredients in the functional foods/dietary supplement marketplace with hundreds of published scientific and clinical studies demonstrating its health benefits. Human clinical studies specifically demonstrate the efficacy of PRP’s from bovine (cows) Colostrum in supporting the immune system.*

Studies show that the immune factors in Bovine (cows) Colostrum are nearly identical to that of humans. Symbiotics® by Naturade® is the world leader in Bovine Colostrum products offering a full range of high quality capsules, powders and chewables made with BIO-Lipid coated Colostrum Plus® with up to 8 times greater solubility than regular Colostrum.*

Your Body’s Remarkable Immune Defense System

Your immune system is a wonderfully complex defense network that employs a wide array of tactics to keep your body healthy. These include Natural Killer Cells and different Cytokines such as Tumor Necrosis Factors, Interleukins and Interferons. The body needs to optimize its immune system addressing the same effect from different angles. Coordination of this effort depends on good communication to keep everything in balance. Key messengers that carry out this communication are called Proline-Rich Polypeptides or PRP’s.

  1. Why Bovine (Cow) Colostrum?
    Research has shown that the immune and growth factors in cow’s colostrum are nearly identical to those in human colostrum. Since bovine colostrum is not species-specific, it works effectively in humans as well as other animals.

  2. Why Do I Need Colostrum, as an Adult?
    Once puberty has passed, our bodies begin the aging process by gradually producing less of the immune and growth factors that help us fight off disease and heal damaged body tissue. Colostrum is the only natural source of these life-giving components. Research has shown that colostrum not only supports immune function, but can help enhance fat utilization for fuel and optimize cellular reproduction). As far as we know, no other substance on the planet can provide all of these marvelous benefits.

  4. What If I’m Lactose Intolerant?
    The amount of lactose in colostrum is scant – 163 mg. in two capsules compared to 13,000 mg. in one 8-oz. glass of milk. Any discomfort would more likely be a sign that colostrum is working effectively in the digestive tract, but please consult your health care practicioner if discomfort persists or if it is serious.

  6. Can I Give Colostrum to my Children?
    Pediatricians recommend that infants, who have not been breastfed, be given colostrum to supplement their formula. We suggest that you consult with your pediatrician for proper dosage information. If your pediatrician is not aware of the importance of supplementing with colostrum, the Center for Nutritional Research can provide him/her with information.

  7. What about My Pets?
    Bovine colostrum works wonderfully with cats, dogs and other mammals because it is not species-specific. The colostrum powder can be sprinkled over their food or a small amount added to their water. Most pets love the taste of colostrum. Encourage them to drink water after they take colostrum.

  8. How Much Should I Take?
    Each person is unique (age, weight, health problems) as to the amount of colostrum needed to achieve an optimal benefit. Remember, colostrum is a food and can safely be taken taken when used as recommended on the label.

  9. Can I Take Colostrum With Other Supplements and Medications?
    Colostrum works in the digestive tract so that all substances taken internally (food, herbs, natural healing substances, and medications) will become more bio available to the body. Although colostrum has no known drug interactions, see your health care practicioner prior to use as you may find that the other supplements and medications that you are taking will have a more pronounced effect.

  10. What is the Difference Between the Powder and the Capsules?
    Research is pointing to the fact that to receive the maximum benefit from colostrum, it should be taken both encapsulated and in powder form. Colostrum should be taken encapsulated, on an empty stomach with a full glass of water to enable the colostrum to reach the small intestine where the immune factors have been shown to do their best work. To receive the optimal benefit from the growth factors (repair body tissue, fat utilization for fuel, anti-aging), colostrum should be taken in powder form so it can mix with the acid in the stomach or mouth. The powder can either be mixed as a shake with water or juice (possibly orange juice).

  11. Are There any Side Effects from Taking Colostrum?
    Side effects are very rare. If you experience any serious or undesirable side effects stop taking immediately and see your health care practioner before resuming use. Due to its detoxifying nature, certain side effects may occur. It’s possible for these toxins to produce minor rashes, bowel changes or flu-like symptoms until they are cleansed from the body.Most side effects stem from other supplements or medications that that are taken with the colostrum that are finally being utilized by the body. If taking any prescription drugs, over the counter medications, herbs or nutritional supplements, consult with your health care provider so that he can adjust or re-evaluate your supplements or medication needs.

  12. I’m a vegetarian. Isn’t Colostrum an Animal Food?
    Although colostrum is an animal food, it has been an important part of the strict vegan diet of India’s Hindu Rishis (spiritual leaders) for thousands of years. In present day India, the milkman delivers colostrum to the wealthy Vegans. It’s interesting that cows are sacred in India, a country where vegetarianism is most prevalent.

  13. Is Colostrum Nature’s Antibody?
    Colostrum has been shown to have many beneficial health effects. However, taking colostrum cannot change the inherent genetics of an individual. Colostrum supplementation does not change our DNA; our parents predetermine our genetic make-up. With any nutritional or dietary supplementation, the hope is to create a healthy being to discourage the proliferation of unhealthy cells. There are numerous studies that exist describing the health benefits of colostrum, and the advantages that are derived from the use of this supplement.

  14. Why is Some Colostrum De-fatted? Does This Minimize the Growth Factors?
    There are no growth factors in the fat content of colostrum. Growth factors are proteins and are not a part of the fat. De-fatting colostrum is important to keep the colostrum from going rancid on the shelf.

  16. Should Colostrum be Pasteurized?
    Absolutely! Cow manure can easily splash onto the udders contaminating them with E-coli, salmonella and other pathogenic bacteria. This creates the potential for contamination of dairy products. Dairy products (for human consumption) must be pasteurized to kill these pathogens. There are two ways of pasteurizing colostrum, the optimal flash (15 second) pasteurization and a slow 30-minute vat process. Flash pasteurization uses the expensive, high-tech equipment found in the modern dairy that does not denature the colostrum. With the less expensive, 30-minute pasteurization process, a huge vat of colostrum is heated from the outside. It takes a long time to heat a large kettle of colostrum to the required temperature. During this interval, bacteria grow in the colostrum. As the bacteria feed upon the colostrum, it denatures and destroys its effectiveness. Most colostrum that is being sold to the public today has been prepared for the animal feed market and has not been pasteurized. Check the label to make certain that the colostrum product you are choosing has been flash pasteurized.

  17. Why is Colostrum Better if it is Collected Over 48 Hours Rather Than the First 6 Hours?
    A high level of IgG (immunoglobulin) may be most important for a newborn calf as it is their sole source of immune protection at birth; however, for humans taking colostrum as a supplement, the level of IgG in a colostrum product is not a benchmark of quality. Although the first milking is higher in IgG, it is subsequently lower in many other important healing components, such as lactoferrin and PRP. In order to obtain a colostrum product that is perfectly balanced, with significant amounts of at least 90 beneficial components found naturally in colostrum, it should be collected over the first 48 hours.

  18. Is Estrogen found in colostrum?
    There is a scant amount of bovine estrogen in bovine colostrum. This form of estrogen is not bio available to humans when taken orally.

  19. Why Can’t I Get Colostrum From A Local Farmer?
    You can. It needs to be refrigerated and consumed before it spoils. Raw colostrum is not pasteurized and contains immune factors from just one cow. This differs from processed colostrum, which is concentrated and provides a broad base of immune factors that have been pooled from hundreds and sometimes thousands of cows.

  20. Why Should Colostrum be fresh processed (not frozen)?
    Quality dairy products, including colostrum, are never frozen because it changes the composition. This is noticeable with the look and taste of milk when you freeze and thaw it. Colostrum’s effectiveness is greatly changed in this freezing/thawing process. Check to make sure your colostrum is fresh processed and never frozen.
