Why take Immune Defense Power Packs?

Your first line of defense to ward off infections and fight diseases is a your immune system. The immune system protects against invading pathogens such as bacteria and viruses by recognizing them as foreign bodies and destroying them once they enter the body.

However, your body can only fight off and destroy microorganisms that cause diseases if your immune system is robust. The immune system, as the words imply, is comprised of many cells and organs that work together to defend the body when a foreign entity is encountered. The immune system recognizes these pathogens as invaders and releases antibodies that attach to antigens of the pathogen and kills them. Your best chance of beating infections is by building a strong immune system so that you have a chance of fighting off infections whenever you are exposed to them. A healthy lifestyle such as exercising regularly, minimizing stress, practicing general good hygiene and consuming a nutritious diet are beneficial to immune health. Some nutrients are especially known to help build and maintain your immune system.  If you feel you are not getting sufficient amounts of the essential nutrients that naturally boost immunity from your diet,  the Immune Defense Vitamin Pack may help.

The Immune Defense Power Pack is designed to improve your immune health and contains immune boosting nutrients  that can give you a good chance of fighting infections. Each packet in the Immune Defense Power Pack contains doctor recommended daily doses of Vitamin A, Vitamin C, Vitamin D, Zinc, NAC (N-acetyl-cysteine), Garlic and Bioflavonids to boost your immune health. 

Benefits of Immune Defense Power Pack

  • Promotes immune health*
  • Supports antioxidant activity*
  • Maintains healthy respiratory function*
  • Supports cardiovascular health*
  • Detoxifies many environmental toxins*
  • Promotes reproductive health*
  • Maintains healthy skin and mucous membranes*

Vitamin A

The role Vitamin A plays in immune health has been known for close to a 100 years. Although one of the best understood function of Vitamin A is its role in maintaining good vision, vitamin A plays a critical role in the development of the immune system and regulating immune response at the cellular level. It is also integral to maintaining health of mucosal lining of the respiratory, digestive and urinary tract, which are the body's first line of defense against infections. Vitamin A has been referred to as an "anti-inflammation vitamin" because it reduces inflammation and provides resistance to infection. Regular intake of Vitamin A is essential for maintaining immune health as its deficiency can lead to decreased immune cell activity and increased risk to infection. (1,2)

Key Benefits of Vitamin A

  • Promotes healthy vision*
  • Supports normal functioning of the immune system*
  • ­Maintains mucus membrane and skin health*

Vitamin C

Vitamin C, also known as ascorbic acid, is an essential water-soluble vitamin that needs to be part of your diet even though most mammals can synthesize it in their body. One of the key function of  Vitamin C in the body is to increase production of infection-fighting white blood cells, known as phagocytes and lymphocytes, which increase the body's ability to fight infection. Vitamin C also boosts immune health by increasing immune cell activity, especially function of T-cells and phagocytosis.  Additionally, vitamin C is as an antioxidant agent that prevents damage of white blood cells from free radicals by acting as a free radical scavenger, thereby strengthening and protecting the body's defense system. (4,5)

Key Benefits of Vitamin C

  • Boosts immunity*
  • Synthesizes collagen, an integral protein present in connective tissue, bones, teeth, blood vessels, gums, joints, ligaments and tendons*
  • Improves iron absorption*
  • Aids production of neurotransmitters and hormones*

Vitamin D3

Vitamin D3 or Cholecalciferol is a fat soluble vitamin that your body can synthesize naturally from 7-dehydrocholesterol when skin is exposed to sunlight. In spite of the ease of vitamin D availability, vitamin D deficiency is fairly prevalent. This is because several factors such as location, season, time of day, skin color, clothing, use of sunscreen and age can influence amount of vitamin D formed. It is important to get daily recommended amounts of vitamin D as it plays several important roles in your body.  One of its role is in the functioning of the immune system. Frequent colds or bouts of flu may be caused by low levels of vitamin D in your system as it interacts directly with cells that fight infection. Deficiency of vitamin D has also been linked respiratory tract infections like bronchitis and pneumonia.(6, 7)

Key Benefits of Vitamin D

  • Improves absorption of calcium and maintains bone health*
  • Maintains normal immune function*
  • Reduces risk of osteoporosis*
  • Supports normal cardiovascular health*


Even though zinc is a trace mineral, meaning it is required in very small amounts, it is essential for maintaining good health. Zinc is required as a cofactor for optimal activity of over 300 enzymes in the human body and plays a crucial role in metabolism of carbohydrates and protein. Zinc plays an important role in supporting immune function by regulating T lymphocytes, decreasing oxidative stress and fighting inflammation. Zinc deficiency decreases natural killer (NK) cell activity as well as interleukin-2 (IL-2) production. Zinc is also involved in DNA synthesis and wound healing, and is also required during periods of growth and development due to its role in cell growth and division. (8,9)

Key Benefits of Zinc

  • Maintains healthy immune function*
  • Promotes wound healing*
  • Supports normal growth and development*
  • Essential for maintaining cell membrane structure and function*

NAC (N-acetyl-cysteine)

NAC is a supplemental form of the amino acid, cysteine, which is a semi-essential amino acid that can be produced in your body from other sulfur-containing amino acids, methionine and serine. Although readily available in many foods, you may choose NAC supplements to increase intake of cysteine. Supplemental forms of cysteine such as NAC are used in the body to promote production of glutathione, which is incorporated into antioxidant enzymes, glutathione peroxidase and glutathione reductase and detoxification enzymes, glutahione S-tranferases. These enzymes help neutralize free radicals by enhancing antioxidant activity, detoxification and breakdown of toxins and other metabolites in the body. NAC supplements may increase immune function by restoring the body's natural killer cells and may reduce symptoms and duration of the flu. (10,11)

Key Benefits of NAC

  • Enhances glutathione production*
  • Detoxifies toxins and pollutants*
  • Supports respiratory, immune and hepatic health through production of glutathione*


Garlic is a root vegetable well known as a food ingredient than enhances flavor and taste. But garlic, which belongs to the Allium family of foods along with onions, chives, leeks and shallots, has been used for its medicinal properties for thousands of years. Garlic is rich in sulfur-containing compounds, namely alliin, allicin, allyl cysteine and allyl disulfide, that have antioxidant activity in the human body. Garlic supports heart health by maintaining blood pressure and normalizing levels of low-density lipoprotein (LDL), cholesterol and triglyceride. Compounds in garlic may also boost immune function by preventing infections, decreasing duration of colds and supporting normal microbial balance. (12,13)

Key Benefits of Garlic

  • Enhances immune functions*
  • Supports heart health*
  • Improves Cholesterol levels*


Bioflavonoids or flavonoids are polyphenolic compounds found naturally in many fruits and vegetables some of which are citrus fruits like oranges, lemons and limes; cherries, grapes, broccoli and onions. Flavonoids work in the body as antioxidants by scavenging free radicals and play a role in the normal response to inflammation, thus playing a role in supporting cardiovascular health. Bioflavonoids also increase vasodilatation, encourage  detoxification and maintain healthy platelet function. (14)

Key Benefits of Bioflavonoids

  • Associated with response to inflammation*
  • Supports healthy cell growth*
  • provide neuroprotective effects*

Count: 30 daily packets (30 AM, 30 PM, 30 garlic)

Recommended Dosage: Take 1 AM packet with your first meal of the day. Take 1 PM packet with your last meal of the day.  Take 1 garlic packet daily, with or without food.
