4Life's TF Canine Complete & TF Feline Complete - ensuring the best overall health for dogs and cats.

This is 4Life's original proprietary extract of transfer factors.  Derived from bovine colostrum, transfer factors are immune system molecules that contain the intelligence codes for immune recognition and balance.  They literally transfer immunity across species from a competent host to a recipient. 

ThyRx™  is 4Life's proprietary thymus complex which contains thymic factors.  ThyRx™ contains important proprietary thymic factors which support T-cells. 

Cordyvant™  is a proprietary combination of glyconutrients (IP6, Beta Glucans and Aloe Vera) which support the innate immune system.  In addition, glyconutrients activate white blood cells to produce antibodies without the help of T-cells. 

Montmorillonite:  Montmorillonite provides a rich spectrum of essential trace minerals that activates enzymes necessary for proper digestion and energy. These trace minerals also help your pet maintain strong bones and teeth. 

Brewers Yeast:   Brewers yeast contains important nutrients that help promote healthy-looking skin and coat.

Note: If your animal is sensitive or intolerant of brewers yeast, use the human formula, Transfer Factor Plus, which is yeast free. Many veterinarians give the human formula, TF Plus, to their animals. The content of the capsule can be sprinkled in the animal's food.

Price List

Some veterinarians recommend the human formula, Transfer Factor Plus, for very sick animals. (see testimonials above). Some people find it easier to give TF in capsules (or mix the small amount of powder in food or water) to very sick animals who have difficulty eating or swallowing. 

The added immune enhancing ingredients in TF plus: ThymuPro & Cordyvant

• ThymuPro: Contains important thymic factors to boost the thymus, which plays a crucial teaching role for your immune system. The thymus acts as the "grade school" of education for T-cells (important immune cells). This education becomes less effective as we get older.

Cordyvant: Provides ingredients that support the innate immune system, the first and instinctive response when your body is threatened. This blend contains important compounds like maitake and shiitake mushrooms, cordyceps, IP-6 and beta glucans.

30-60 lb. One capsule 2x daily

Note: Although Transfer Factor™  and Transfer Factor Plus™  are best given throughout the day, satisfactory results have been obtained by giving the dose once a day.
