If you are going to fly on a plane; if I’m going to be in big crowds; if I feel like I’ve been around a whole bunch of people that are sick, if you already have a weakened immune system. This is when we recommend you take Pur Immunity™.

We suggest taking one Pur Immunity™ daily, in the fall when school starts. This is when we see the most Viral Infections, and throughout the winter seasons from February – March as the flu & cold season starts to end.

As soon as you get sick, start to feel under the weather or have an ongoing infection; we suggest taking up to 3 capsules, 2 times a day.

Always consult your Physician or A Health Care provider before taking.


Houttuynia cordata is used in folk medicine for diuresis and detoxification and herbal medicine for its antiviral, antibacterial and antileukemic activities. Houttuynia cordata was used by Chinese scientists to tackle SARS as it is conventionally used to treat pneumonia. Houttuynia cordata is ranked among the top ten medicinal herbs in Japan and has been used traditionally to treat various types of infections, inflammation, hypertension, sinusitis, pulmonary tuberculosis, etc. A study published in November, 2008 demonstrated that Houttuynia cordata is non-toxic to laboratory animals. Houttuynia is also an effective antihistamine and anti-inflammatory.

As we age, the thymus gland, which is charged with the task of managing immune function, begins to decrease in size. This decrease in size has been linked to immune dysfunction and has been closely correlated to a decline in CoQ10 production. When CoQ10 is returned to optimal levels, the thymus appears to become more youthful in appearance and function. In one study on elderly subjects, a deficiency of coenzyme Q10 was linked to a decrease in the function of natural killer cells. These cells are critical in the fight against viral infection and cancer. Other studies demonstrated that coenzyme Q10 was important in the function of both T-cells and macrophages-two important classes of immune cells. Coenzyme Q10 plays a very important role in a healthy immune response. A deficiency in this vital nutrient can have catastrophic effects on health and vitality.

Quercetin has been the subject of recent studies of its potential anti-flu properties. A recent animal study showed that quercetin significantly reduces susceptibility to the flu. Mice were exposed to the influenza virus A/Puerto Rico/8/34 (H1N1) flu virus under various conditions, including increased stress from exercise. The mice given quercetin were able to offset the adverse effects of stress and showed much less susceptibility to the flu.

There have been a number of studies showing that quercetin directly interacts with different types of viral infections, reducing their ability to infect. An August 2009 cell study showed that quercetin interfered with the gene signals that enable hepatitis C virus production. The researchers concluded that “Quercetin may allow for dissection of the viral life cycle and has potential therapeutic use to reduce virus production with low associated toxicity.”

ALA has the ability to recycle key antioxidants, including vitamins C and E, glutathione, coenzyme Q10 and even itself. Dubbed "the universal antioxidant," ALA assists B vitamins in producing energy from proteins, carbohydrates and fats. ALA also helps the body convert glucose to energy. ALA is the only antioxidant that has been demonstrated to increase Glutathione production, essential for healthy immune system functioning. Glutathione is the body's main water-soluble antioxidant and a major liver detoxification agent. Glutathione breaks down in the digestive tract before it reaches cells. Therefore, ALA's ability to boost glutathione levels is important. ALA also plays an important role in the Krebs cycle, the body's main process for turning carbohydrates into energy. Alpha lipoic acid neutralizes a wide variety of free radicals circulating through the body, molecules that can damage cell membranes.

N,N-dimethylglycine HCl is derived from the original amino acid glycine through a methylation process. The structure of its chemical makeup is very similar to choline, a related chemical. Dimethylglycine is part of the B-chain of vitamins, and thus is given the name Vitamin B-15. It is also known to be called pangamic acid and can be useful in reducing recovery time after difficult exercise and also improves the body's ability to intake and use oxygen.

Similar to the effects of betaine, dimethylglycine is able to donate a methyl towards necessary enzymatic reactions. This ability to donate one of its methyl groups is very crucial in the synthesis and production of important brain chemicals. Decent levels of glycine in the body are responsible for a general overall feeling of health or well-being. DMG improves oxygen utilization, detoxification, cell protection, immune system modulation, and enhances healing.
