Abstract: A drink includes an edible liquid or semisolid preparation and transfer factor. The drink may also include lactoferrin and one or more preservatives. An edible preparation includes a fruit component and transfer factor. The fruit component may include at least one oligoproanthocyanidin-containing fruit. The edible preparation may also include lactoferrin. One or more preservatives may also be included in the edible preparation. The drink or the edible preparation may be sterilized or pasteurized.

Abstract: A composition for eliciting a T-cell mediated immune response in a subject includes transfer factor from at least two different types of source animals. For example, the composition may include mammalian transfer factor and nonmammalian transfer factor. An example of the composition includes a combination of a colostrum-derived product, which includes the mammalian transfer factor, and an egg-derived product, which includes the nonmammalian transfer factor. Additionally, the egg-derived product may be substantially free of fat. Methods for forming the composition and eliciting T-cell mediated immune responses in subjects that have been treated with the composition are also disclosed.

Abstract: Compositions, systems, and methods for enhancing the ability of a subject to heal itself following an infection include administering a composition that includes transfer factor to a subject. Administration of such a composition or combination of compositions to a subject may result in improving the subject's overall antioxidant profile, increasing the concentration of chemical antioxidants present in the subject, increasing the efficiency with which the treated subject's enzymatic antioxidants work, increasing the efficiency and/or activity of the treated subject's detoxification enzymes, and improving cellular and molecular health of the subject.
