This stack is ideal for individuals seeking to restore a weakened immune system, and boost natural defense mechanisms against viral, bacterial, and other foreign invaders.

  • Boost Immune Function

    Harnessing Thymopoietin, Thymulin, and Thymosin peptides to enhance immune cell programming and optimize defense mechanisms.

  • Improve Natural Response to Sickness

    Colostrinin and IgA, IgG antibodies synergize, fortifying the body's innate response against invading pathogens and threats.

  • Reduce Recovery Time

    LEAP-2 Peptide and Lactoferrin starve pathogens, supporting immune strength, reducing recovery time, and enhancing resilience.

  • Amplify Antimicrobial Defense

    Bovine Beta-Defensins, Cathelicidins, and Ergothioneine Peptide offer broad antimicrobial activity, fortifying against bacterial and viral invaders.

  • Bioavailable Nutrients

    Highly bioavailable micronutrients from natural sources deliver superior absorption, maximizing nutrient utiilization for immune system health.

Histamine & Immune

Histamine & Immune is the foundational supplement included in the Immune Support Stack. It provides unique and essential support found in grass-fed and grass-finished thymus, lung, spleen, liver and kidney.

Organ Nutrients

Thymus extracts contain hormones like thymopoietin and thymulin that can safeguard the body from the development of cancer, allergies, rheumatoid arthritis, and other autoimmune disorders by enhancing cell functioning.

Lung is rich in vitamin B12, which acts as an immunomodulator for cell immunity. It also contains antimicrobial peptides that have been shown to improve immune health.

Spleen has high levels of heme iron, the most bioavailable form of iron, to support the nervous system and immune health. It is also rich in niacin, which is crucial for metabolic health, and selenium, a key player in thyroid function.

Liver is the single most nutritious natural food on the planet, both in terms of density and variety. It is incredibly rich in vitamins, minerals, peptides and enzymes to support immune, reproductive, digestive, musculoskeletal, and nervous health.

Kidney contains high levels of vitamin B2 and the mineral selenium, which is required for optimal immune function, helps decrease oxidative stress, and is even associated with the prevention of certain cancers.

Immune Support Stack


The combined power of Histamine & Immune, Bone Marrow & Liver, and Grass-Fed Colostrum includes vital and potent essential nutrients.

Thymopoietin and Thymulin

Essential peptides for immune cell programming and activation of the immune system.

Diamine Oxidase (DAO)

Supports overall immune health, histamine metabolism, and digestion.

Thymosin fraction 5 and thymosin alpha-1

Peptides that are potent stimulators of the immune system and enhance immune cell functioning.

Liver Expressed Antimicrobial Peptide

Also known as LEAP-2. This peptide is involved in immune response and glucose metabolism.

Thymosin beta-4

Important peptide in stimulating pituitary hormones essential for reproductive function.

Hepcidin Peptide

A peptide directly involved in iron metabolism as well as the innate immune response.

Thymic humoral factor

Increases the immune response, especially to viruses.

Kidney-specific peptides

Reduce the concentration of oxalates in the urine and calcium deposits in the renal tissue, as well as preventing free-radical induced damage.

Bovine Beta-Defensins and Cathelicidins

Peptides known to have broad antimicrobial roles in the body.

Vitamins A, D, E, K2

Get these vitamins in a super bioavailable form that play critical roles in overall immune and bone health.

Splenin, Tuftsin and Splenopentin Peptides

Peptides exclusively found in splenic tissue which enhance immune function.

Riboflavin, Folate, B12, and Choline

Essential for red blood cell formation, brain, reproductive, and cardiovascular health.

Heme iron

Crucial for brain health, energy, and exercise performance, as well as immune function.

Copper, Biotin, and CoQ10

Crucial for metabolism, mood, and energy, as well as the health of skin, hair, and nails.


A B3 vitamin essential for cardiovascular health, mood, cognition, and energy.


A critical mineral for thyroid function (iodothyronine deiodinanses) and immune health/antioxidant defense (glutathione peroxidase, thioredoxin reductase).

Ergothioneine Peptide

An amino acid found in liver, kidney, and bone marrow found to support detoxification and longevity pathways.

Red and yellow bone marrow

Abundant in peptides, growth factors, and stem cells to promote and support the formation of red blood cells, cartilage cells (chondrocytes), bone cells (osteocytes, osteoblast & osteoclasts), and other vital tissues found throughout the body.

Essential fatty acids including omega-3 fatty acids, EPA & DHA

Play a critical role in the immune system, brain and cardiovascular health, as well as muscle recovery.


Support the immune system and formation of red blood cells, white blood cells, and platelets.


Peptide hormone shown to support immune, metabolic, and cardiovascular health.

Tissue-specific proteins, hormones, growth factors, and peptides such as bovine cathelicidins

Show broad antimicrobial activity and are involved in the immune response.

Immunoglobulins (IgA, IgG, IgM, IgD, IgE)

Antibodies that play an integral role in immune defense mechanisms.

Transforming Growth Factors - Alpha & Beta (TGF-a & b)

Stimulates growth and differentiation of various connective tissue, including bone and cartilage, and is crucial for wound healing, gut healing, as well as DNA synthesis and repair.

Proline-rich Polypeptides (PRPs), like Colostrinin

Crucial for thymus gland support (command center for immune defense), growth and differentiation of B lymphocytes, and modulating the immune response.

Insulin-like Growth Factor- I & II (IGF-I & -II)

Found abundantly in colostrum and helps balance blood sugar, increase HDL, build lean muscle, and aids in the metabolism of protein, fat, and carbs.


Crucial iron-binding protein which helps starve bacteria of iron needed to reproduce and modulates a powerful immune response to invading organisms.

Epithelial Growth Factor (EGF)

Crucial for skin health and wound healing.

Colony-stimulating Factor-1 (macrophage colony-stimulating factor)

Stimulates stem cells to differentiate into macrophages — immune cells that "eat" or clean up dead pathogens/debris from inflammation and infection.

Cytokines, Interleukins, Interferons, and Lymphokines

Cell signaling molecules crucial for balancing inflammation and boosting T cell activity as well as the production of antibodies. These communication molecules have been identified as important molecules for treatment of cancer, pain, and various diseases.


Identified through research to induce selective apoptosis (cell death) of cancer cells and highly effective against various viruses.

WOW!! I don’t have any allergy symptoms 
anymore. I began noticing an improvement almost immediately.
