Helps Relieve Cough & Mucus Build Up*

ImmunityMD® Plus formula stimulates lung tissue function and helps alleviate excess mucus accumulation, aiding respiratory health.* This first-of-its-kind, scientifically proven supplement includes clinically effective dosages of South African Geranium, elderberry, NAC, vitamin E, vitamin D, and vitamin C, working synergistically to support the function of every single cell involved in the body’s immune response system, particularly as it relates to lung health. *

Stimulates Immune System Response & Promotes Respiratory Tract Relief*

  • South African Geranium also known as wild geranium, is traditionally used to soothe the upper respiratory tract.* This powerful botanical is clinically proven to help increase the body’s natural healing rate and has been scientifically shown to help relieve common headache, fatigue, cough, and nasal drippage, making it extremely effective at stimulating the immune system. *
  • NAC, an essential compound due to its powerful ability to help improve glutathione production. Glutathione is one of the most important antioxidant enzymes in the body that helps clean and fix damaged tissues. NAC helps thin out overly thick mucus, allowing for it to be coughed up and removed from obstructing the respiratory pathways. *
  • Vitamin E is essential for maintaining immune health. As we age, our ability to retain vitamin E diminishes and with it our ability to promote immune system function. Multiple clinical studies show the key benefit of vitamin E is its ability to improve t-cell production in the thymus. T-cells are a broad class of immune cells responsible for identifying and taking out non-host cells. When the body’s T-cell populations are healthy, our immune response is properly maintained. *
  • Vitamin C amplifies the effects of vitamin E by helping recycle spent vitamin E while also positively influencing the adaptive and innate immune system by strengthening epithelial tissue as well as improving immune cell activity. Epithelial tissue is the lining of the digestive and respiratory tracts and is the first main defense of our immune system. The epithelial cells form a physical barrier that keeps bad things out while allowing nutrients to freely pass. As the epithelial cells degrade, this barrier becomes weaker and weaker allowing higher levels of contaminants to pass. By promoting epithelial health, vitamin C stimulates this first line of defense. *
  • Vitamin D3 in the form of cholecalciferol, is an integral part of respiratory and immune health, due to its ability to encourage production of specific molecules responsible for harming lung tissue and support the function of immune cells, including T-cells and macrophages, that protect your body from foreign cells. *
  • Packed with antioxidants, elderberry berries and flowers are packed with immune-boosting properties that can help the body heal faster, lessen stress, while also helping protect your heart. *
  • Zinc is an essential trace mineral necessary for almost 100 enzymes to carry out vital chemical reactions. It is vital in the creation of DNA, growth of cells, building proteins, and supporting a healthy immune system.
  • An essential micronutrient, chromium has been shown to play a significant role in boosting the immune response by supporting increased production of T-Cells, B-Cells, cytokine, and macrophages. *
  • Marshmallow root helps increase the body’s healing time and activates the immune system, specifically by expediting a process called phagocytosis, which cleans up damaged or dead cells from the body. Marshmallow root also supports the mucosal relief activity of NAC by being a natural source of mucilage, a lubricating compound that alleviates irritation of the respiratory tract sometimes caused by excessive coughing. *

ImmunityMD® Plus is Potent Immune and Respiratory System Support*

In clinical trials, significant improvement began at the 3 month marker.*

  • Month 1

    In more than 11 clinical trials, improvements in common cough, shortness of breath, fatigue, and wheezing began to occur between 1 to 2 weeks after starting supplementation.*

  • Month 2

    Increase in the production of glutathione, a powerful antioxidant found in every cell of the body, which supports vital functions, including immunity, regeneration, and lung health.*

  • Month 3 & Beyond 

    Strengthened T-cell and white blood cell production work to dramatically stimulate immune and respiratory system functions.*

Dr. Brian Greenberg

As a UCLA trained Pediatrician, Allergist and Immunologist I have spent almost 30 years helping patients of all ages maintain their respiratory health. In my quest to stay cutting-edge and to utilize all vehicles possible to take care of my patients, I helped introduce groundbreaking therapies and have championed the use of natural methods to improve our body’s own immune system to promote health and healing.

This is why I stand behind 1MD’s ImmunityMD® Plus, a truly revolutionary immune and respiratory system supplement, clinically proven to promote proper lung function, stimulate and maintain the body’s proper immune response, and effectively stop foreign cells from gaining a foothold in our body.

This one-of-a-kind immunity and respiratory formula contains clinically effective dosages of wild geranium, elderberry, NAC, vitamin E, vitamin D, and vitamin C, that work synergistically with the recommended daily allowance of zinc, chromium, and marshmallow root to provide unparalleled whole body health.

In my opinion, 1MD has created the best immune and respiratory health supplement on the market, by combining these highly bioavailable, clinically proven nutrients. I recommend ImmunityMD® Plus to anyone looking to encourage increased antioxidant activity, aid respiratory system performance, and maintain a strong healthy immune system.

A Groundbreaking Formula with Clinically Effective Ingredients That Actually Make a Difference*

ImmunityMD® Plus combines clinically studied dosages of six powerful, immune-support ingredients shown to promote effective lung function and health.*

You can rest assured knowing there are never any harmful fillers or additives

What are people saying?

Using IMmunity MD has really helped my respiratory system...

I feel stronger & healthier after taking 1MD Complete Probiotics and 1MD Immunity for over a month...I think the Immunity supplement is helping my overall health. I’m Jazzercising, playing tennis and enjoying life.

This is an amazing product. I decided to buy one bottle and see if there was a change in my breathing...I feel better than I had been feeling. I recommend this product to everyone. I have energy now as well.

We started using this Immunity MD Plus a few months ago and feel the boost required to fight off seasonal issues. We are very pleased with this product.

I truly recomend this product to everyone

I do seem to have more energy. I was just concerned with the amount of vitamin D3 (4000 IU per capsule), so am taking only one capsule per day. I reviewed the ingredients and am pleased that this contains elderberry, which is so important in [winter].

Seriously find this product especially useful now...I definately make sure to take this product everyday. Have been reordering for both me and my husband. Highly recommend it. And I will be reordering again.

On my second bottle. It’s amazing how it makes me feel...At almost 69, working night shift, working out 4 times a week. This has made a great difference in how I feel. Don’t hesitate to order this.

With the current [situation] this product has helped build up my immunity. So far, so good! Would recommend highly.
