Dr. Atmika Paudel, PhD says... The functions of the immune system mentioned in the article below are medically correct.

Immune system supplements should be used by anyone who suffers from yeast infections so your natural killer (NK) cells can help in the fight against these infections. NK cells can destroy a yeast cell in 1/100th of a second.

They also kill bacteria, viruses, cancer cells, and all foreign pathogens. They literally patrol the body looking for foreign invaders that can adversely affect your health and kill them. Many people that have yeast infections have a low NK cell count as verified by medical lab testing and are also low on antioxidants in their blood plasma levels.
They sometimes have low white blood cell counts which includes the neutrophils and macrophages which are our first line of defense. Immunoglobulin antibody counts are usually low; especially IgA, which protects the mucous linings in the body.

As always, being the skeptic that I am, I always look for research and proof for any specific immune system supplement does what they say it does. I want to see the research on that brand, that product, not just the research on the contents. I want to know that it does indeed work, I want them to prove it to me, or I won't take it, or ever recommend it. But before I get to my recommendations to boost the immune system, I want to explain how NK cells work.

Dr. Vibhuti Rana, PhD says...

I agree with what the section above has to say about immune supplements. They strengthen the immune system and makes it capable of fighting off virulent pathogens or other disorders involving the immune system. A weakened immune system not only leads to adrenal fatigue or a leaky gut, it may also invite myriad of infections, including a persistent yeast attack by Candida species. Therefore, it’s best to incorporate healthy supplements in the diet and beat the fungal infections.

Natural Killer Cells To Boost the Immune System

Natural killer (NK) cells, white blood cells from our "immunologic army", are constantly on the alert, circulating throughout the body looking for cancer cells or cells infected with viruses, bacteria, or fungi. Approximately 15% of the white blood cells in the peripheral blood are NK cells. In addition to residing in the peripheral blood, these cells are abundant in the spleen, an organ that filters circulating blood. The NK cell's position in the peripheral circulation and the spleen enhances its chance of coming in contact with microorganisms that are trying to invade our bodies.

In addition to killing, NK cells have another major function. These cells help regulate the immune system response. They do so by secreting various cell to cell communication signals called cytokines. Cytokines alert other cells of the immune system immunologic army to the fact that there are abnormal cells present in the body, and then activate these cells.

For example, NK cells secrete particular cytokines that cause macrophages, another white blood cell, to kill an invader. The invader may be a cancerous cell or bacteria, viruses, yeast, or fungi. Regardless of the methods chosen, NK cells are usually successful at accomplishing the goal of killing their prey.

So, as you can see, if we boost the immune system with immune system supplements and increase the NK cell activity we can kill all of the yeast infection anywhere in the body, along with all foreign and harmful pathogens.

The effects of foods on the immune system might surprise you but everyone should read this and be aware of what effect foods can have on the immune system. However, to be absolutely certain of which foods affect you and your unique physiology, you must be blood allergy tested.

Metabolic acidosis will have an effect on your entire body leading to a weakened immune system and many diseases. These webpages talk about this condition and its relationship to yeast infections and how you can balance your pH levels.

Dr. Vibhuti Rana, PhD says...

The information mentioned regarding the role of natural killer (NK) cells in immune regulation is correct. Our body’s innate immune system has these NK cells that has a killing tendency for faulty cells of the body (e.g., cancer cells), or infected cells (e.g., virus, bacterium, or fungus-infected). Once the NK cells get activated, they function by releasing various cytokines like interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α), granulocyte macrophage colony-stimulating factor (GM-CSF), and chemokines. These cytokines can regulate the function of other innate and adaptive immune cells (1). Due to this cytolytic (cell-killing) ability, it has shown promising results for treating hematological malignancies.

Apart from their rapid response against infected cells, studies also suggest that NK cells are found in placenta and are involved substantially throughout pregnancy (2). As the name suggests, they do not require prior preparation like cytotoxic T lymphocytes. On their surface, they have activation and inhibition receptor molecules, which ultimately control their killing action upon encounter with another cell. These receptors switch on or off depending upon whether the encountered cell is ‘self’ or ‘non-self/infected’ (MHC-I induced NK cell education) (3).

The section above, and several other sources suggest the  role of NK cell modulation to improve organ transplantation, encourage antitumor therapy, and manage inflammatory and autoimmune disorders.

Immune System Supplements That Work

The next four links are about Glyconutrients that the cells use to talk to one another. Glyconutrients can calm an overactive immune system that doesn't recognize your own bodies cells. Or stimulate an under active immune system that just can't seem to get it together by 1743%.

Profase, I developed this probiotic myself and if you click on over and read the research on the bacteria in the formula; I think you will agree it definitely is medically proven to boost immune function.

Lactoferrin is very good immune system supplement for yeast infections since it not only directly kills yeast, but also stimulates the immune system to do the same. It is so strong that pregnant women are advised not to take it.

Ascorbates, Lysine, and Proline are used by the NK and T-cells in huge amounts when the body is under attack from any infection or disease. They are also absolutely necessary for cellular health since they are the raw material that makes collagen, which forms about 50 to 55% of every cell in the body. The other main component of cells is good fats, especially Omega 3's. This is the most basic vital nutrient that the body must have to remain healthy, because every virus, cancer, and many other diseases travel thru a weak Collagen Matrix.

Colostrum is the old standy immune system supplement for the immune system function because it works. I highly recommend it for babies and children with yeast infections. It works very well for those that are deficient in IgA antibodies, the antibody that defends the mucous lings in the body from yeast.

Beta Glucans is very good for stimulating neutrophils and macrophage activity. The two white blood cells directly responsible for killing yeast and fungi.

Thymic Protein A is an outstanding immune system supplement that activates immature t-cells that migrate from the bone marrow to the thymus gland to be activated. Thymic atrophy occurs in all of us after the age of 20 and is one of the biomarkers of aging.

Marine Phytoplankton is a complete whole food source for all life. The guy that developed the process to commercially grow this had a rare form of cancer, he says marine phytoplankton cured him.

Medical Review by Dr. Atmika Paudel, PhD

The article talks about immune system and the ways to boost the immune system. There are two strategies that human and vertebrates apply for immunity: innate immunity and acquired immunity. Innate immunity is the first line host defense that includes natural killer cell, which the article is focusing upon.

The functions of immune system mentioned in the article is true. Immune system is, indeed, required for fighting off pathogenic microorganisms. Maintaining the immune system is very critical for staying healthy. If the immunity is weakened and compromised, body is prone to infections. Yeasts such as Candida albicans, are commensal as well as opportunistic pathogen, which are waiting for an opportunity to invade the body to establish infection. Compromised immune system will provide that opportunity for pathogens and that is the reason why keeping immune system boosted is important. This becomes more important in cases of elderly and infants who have weak immunity. And it is also important in people who are taking other medicines such as corticosteroids.

The Centers for Disease Control and Prevention has mentioned about the medications that weaken the immune system and their relation to fungal infections on this webpage.

In summary, keeping your immune system boosted is very important to prevent infectious diseases, and prevention is always better than cure.
