About Transfer Factor

4Life Transfer Factor® products

Transfer Factors are a class of messenger molecules that provide valuable immune information to better help your immune system recognize, respond to, and remember potential health threats. These memory molecules are derived from colostrums—nature’s first supplement—and are the first nutrient you receive when you are born. Nature knows best what your body needs, and these products provide an effective level of health support unlike anything else.


A recent clinical study showed that 4Life Transfer products boost the production of the antibody IgA by an average of 73%. Another study revealed a 437% increase in the activity of Natural Killer cells.

Feline Complete - Transfer Factor for your Cat. It has been said that some of the best lessons in life can be learned from cats, like when you are hungry—eat, or when you are tired—nap in the sunlight. There are approximately 65.8 million cats in the U.S., with one out of four households in America owning at least one cat. Most cats will reach about 11 or 12 years of age and some, although very few, have been known to make it to 18 or 20. Put all of this together and you have tens of thousands of cat lovers enjoying years of quality companionship. Transfer Factor Feline Complete can help make those years even better by providing your cat with the vitamins and minerals, antioxidants, amino acids and protein necessary for health and longevity.
