Colostrum Supplement - Nutrient Complex to Boost the Immune System
Colostrum is a dietary supplement containing colostrum standardised to 30% immunoglobulin G, the main type of antibody in the immune system. It is delivered in DRCaps™ to ensure optimal protection and absorption of colostrum’s delicate components.
What exactly is colostrum?
Colostrum is the first form of mother's milk produced by the mammary glands and the very first nourishment a breast-fed new-born baby receives, albeit for a very brief period – the first 24-48 hours of life (post-partum colostrum).
This honey-coloured substance contains fewer major minerals than milk (such as calcium and phosphorus) but a lot more trace elements including zinc (essential for good immune system function), iron and selenium. With its richness in immunoglobulins (antibodies) and essential nutrients, colostrum enables a new-born baby to fight infection from its new environment (1), while waiting for its own immune defences to start working.
What is colostrum composed of?
Few nutritional substances have as many essential elements as colostrum. It contains a large number of proteins, particularly immunoglobulins (antibodies) and albumin, is rich in lipids (primarily long-chain fatty acids) but low in sugar, and also contains vitamins (A, D3, E, C, B1, B2).
In addition to these vital elements, it is composed of substances that support good immune system function such as zinc, antibodies (IgG, IgA, IgM, IgE, IgD), and cytokines, a large group of important molecules that transmit intercellular signals. Cytokines are essential mediators in immune regulation, specific regulators of epithelial cell growth and development, and factors in negative inflammation control.
Last but not least, colostrum contains growth factors, substances that regulate the production and growth of certain cells.
The most important of these include:
- insulin-like like growth factor (IGF), which is the most abundant component in bovine colostrum and plays a key role in child growth;
- epidermal growth factor (EGF);
- fibroblast growth factor (FGF), which generates new blood vessels and supports their activity;
- platelet growth factor, which ensures cell division and growth as well as the formation of new blood vessels;
- transforming growth factor, alpha et beta, essential for tissue regeneration and cartilage formation.
The reasons why sportspeople choose to take colostrum
Athletes who train intensively or who have recently competed at an intense level are at increased risk of developing symptoms associated with respiratory infections (2-6) or temporary inflammation (linked to the cold, pollution, exertion … ). Repeated intense exercise actually leads to a temporary drop in white blood cells (leukocytes), making the immune system less effective.
Most of the time, this is just a simple cold, but these symptoms can disrupt training and impair short- and long-term performance.
Other factors can compromise an athlete’s immune system:
- competition-induced psychological stress;
- lack of sleep linked to exercise intensity and/or stress;
- exposure to extreme conditions (altitude, cold…) ;
- being under-nourished.
Three good reasons to try our supplement Colostrum
- Colostrum is a viscous liquid with a bitter taste and unpleasant odour: it is generally considered unsuitable for human consumption. Encapsulating it allows you to benefit from its rich composition without having to suffer its unpleasant taste.
- Compared with milk, it is 10-20 times richer in vitamin A, 17 times richer in iron (7) and 50-300 times richer in anti-infectious agents such as lactoferrin, lysozyme and lactoperoxidase.
- The use of DRCaps™ technology ensures optimal protection and absorption of colostrum’s fragile components.
How should the supplement Colostrum be taken?
We recommend taking 2 capsules a day, which equates to 1000mg of colostrum standardised to 30% immunoglobulin G.
Very few adverse side-effects have been reported in relation to taking colostrum, with the exception of mild gastrointestinal problems at the start of supplementation. The only contraindication to taking bovine colostrum concerns those allergic to dairy products.
Alongside colostrum supplementation, those engaged in intensive sports activity are advised to adopt the following measures (8) :
- eat a diet that meets their increased energy needs containing all essential nutrients;
- take care to consume enough protein to maintain or increase muscle mass;
- take a vitamin D supplement, from the beginning of autumn through to spring, to support healthy immune system function. Deficiency in vitamin D is common among athletes (9-10), especially those who do most of their training indoors;
- consume 30g-60g of carbohydrates an hour during intensive training sessions;
- take a zinc supplement a few days before the start of an important competition;
- avoid other sources of stress as much as possible on a daily basis;
- try to get good quality, restorative sleep (at least 7 hours a night) ;
- do not binge-drink.
