Bovine Colostrum and Transfer Factor – the Power of Nature in a Capsule

What is bovine colostrum?

Bovine colostrum (BC) is the main ingredient used in 4Life Research’s Transfer Factor dietary supplements. Its importance for health has been known since ancient times and is now being rediscovered by modern science. Studies confirm that bovine colostrum contains immune-active components that may be beneficial for both humans and animals. It’s a natural ingredient, and that means safety and versatility.

What do scientists say about colostrum?

In the journal Nutrients, researchers Raymond John Playford and Michael James Weiser write:

Bovine colostrum (BC) is the first milk produced after birth and is a rich natural source of macro- and micro-nutrients, immunoglobulins, antimicrobial peptides, and growth factors. There is strong evidence that BC is essential for the nutritional and immune support, growth, and development of newborn calves. It is commercially available to promote general health and immune support. Increasing evidence suggests it may also benefit children and adults, as well as athletes by supporting exercise and recovery. Its application is not limited to humans – data also confirm its role in animal husbandry and the wellbeing of livestock and pets.

What immune-active ingredients are found in colostrum?

Supplement producers use colostrum primarily for its immune-related substances. These include:

• Large immune molecules (immunoglobulins IgM, IgA, IgE, IgD, IgG)
• Medium-sized enzymes like lactoferrin and lactoperoxidase
• Small proteins called cytokines (e.g., interferon, interleukins, TNF)
• Very small peptides known as Transfer Factor – unique immune-supporting messengers

These last components – Transfer Factors – became the foundation of 4Life’s patented line of Transfer Factor supplements. They are the only such products on the global market.

Who can use colostrum-based supplements?

Bovine colostrum can be used by people of all ages – and even their two- and four-legged friends (and the feathered ones too!). It is considered safe and natural.

According to the above-cited research: Colostrum has a high safety profile, is suitable for all age groups, and is delivered in a natural form that limits self-deactivation after oral intake. This should support wider acceptance and compliance among consumers aiming to optimize their immune and digestive health.
