Key Benefits at a Glance:

  • Reduces cold and flu symptoms quickly
  • Reduces the frequency, severity and duration of upper respiratory tract infections
  • Combines Andrographis with advanced Nitric Oxide (NO) technology to prevent infection and improve energy levels
  • NO is an antimicrobial to help fight germs naturally
  • Increases circulation to support recovery from illness

Product Description:

ColdNOx is essential during cold and flu season for those who have a weakened immune system and are prone to falling ill. ColdNOx contains Andrographis paniculata extract in combination with a supplemental source of nitric oxide (NO), potassium nitrate. This formula is the World's First Andrographis paniculata enhanced with a natural source of supplemental nitric oxide. This novel formula reduces the frequency, severity and duration of upper respiratory tract infections. NO acts as a natural antimicrobial and increases circulation to support recovery. Green tea extract and citric acid are also included in AOR’s proprietary NOx3,2,1 Technology blend as synergistic agents to improve the body’s conversion of nitrate to nitric oxide and to enhance its effectiveness.

ColdNOx is our pick as the best cold & flu fighter available today.  It combines Andrographis, an immune-boosting herb with advanced nitric oxide technology. NO provides the same health benefits as eating several large servings of dark leafy greens  in one small capsule and is proven to prevent infection, protect the stomach, improve energy levels and  exercise performance, and prevent vascular disease. When combined together, Andrographis & NO help you naturally fight germs and relieve cold symptoms fast! 

Background Information:

Andrographis paniculata is a plant found primarily in Asia and India. In Traditional Chinese Medicine, it is used to remove heat, counteract toxicity and reduce swelling. In Ayurvedic and Thai medicine, it is used to treat fever associated with infectious diseases, and Scandinavians have used it as a cold and flu remedy.

Upper Respiratory Tract Infections, Pharyngotonsillitis, Cold and Flu

Andrographis has been shown to reduce the frequency of upper respiratory tract infections (URTIs) as well as the duration and severity of URTI symptoms of the common cold and sinusitis, bronchitis, pharyngotonsillitis and pneumonia in just 2-4 days. Such symptoms include tiredness, sleeplessness, sore throat, nasal secretions, earaches, phlegm, coughing and headaches. There is also preliminary evidence of a preventive effect. Adverse events were mild and infrequent. Collectively, the data from seven double-blind controlled trials suggest that A. paniculata is superior to a placebo in alleviating the subjective symptoms of uncomplicated URTIs.

What Is Nitric Oxide?

Nitric oxide is an essential molecule that has a wide range of beneficial effects throughout the body. Its primary role is to facilitate communication between the body’s cells. It’s known as a powerful effector molecule and functions as an EDRF (endothelium-derived relaxation factor). Green leafy vegetables contain very high levels of nitrates, for example, celery, spinach and beetroot contain over 250mg of nitrate per 100g serving. Diets rich in fruits and vegetables such as the DASH, Mediterranean and Japanese, are associated with good health and protect against disease due to their high levels of nitrates.


In a study of uncomplicated respiratory disease in 39 children between the ages of 4 and 11 years, A. paniculata significantly decreased the amount of nasal secretion and nasal congestion. It also accelerated the recovery time, whereas another herbal preparation containing Echinacea extract did not show the same efficacy. The treatment was well tolerated and the use of standard medication was significantly less in the group using Andrographis versus the groups using the other herbal brand or any other standard medication.

In another study in 107 school children, a randomized, placebo controlled, double-blind investigation evaluated a standardized extract of A. paniculata in the prophylaxis of the common cold during the winter season. The children received either 200 mg of the extract or a placebo daily for 3 months and were evaluated each week by a physician. During the first two months of treatment, there was no difference between the two groups. However, in the third month of treatment, there was significant difference in the occurrence of the common cold in the treated group (30%) when compared to the placebo group (62%).

A study of a treatment group consisting of 95 individuals involved taking an herbal preparation containing A. paniculata for 5 days. The results of this study also showed that A. paniculata has a positive effect in the treatment of acute URTIs and helps relieve the inflammatory symptoms of sinusitis.

One hundred and fifty-two adult patients with pharyngotonsillitis were enrolled in a randomized double blind study to assess the efficacy of Andrographis paniculata. The patients were randomized to receive either paracetamol or 3g/day of Andrographis paniculata or 6g/day of Andrographis paniculata for 7 days. The efficacy of paracetamol or high dose Andrographis paniculata was significantly more than that of low dose Andrographis paniculata at day 3 in terms of the relief of fever and sore throat. The clinical effects were not different at day 7.

Inhibiting Pathogens

Andrographis is thought to inhibit the growth of certain pathogens and inhibit access to cells by microbes and the toxins they produce. Studies have also found that Andrographis can reduce the symptoms and severity of colon issues such as acute diarrhea, bacillary dysentery (bacterial infection of the gut mucosa with blood in the stool) and urinary tract infections.

Most people turn to antibiotics for eliminating infections. However, alternatives such as Andrographis paniculata are beneficial for both bacterial and viral infections.

Healthy Tidbits

In this century, the world will have more people living into their 80s and 90s than ever before, with the number of people 80+ set to quadruple between 2000 and 2050.


Increased life expectancy is largely due to improvements in public health, and healthy ageing is linked directly to health in earlier stages of life.


Although it is natural for biological processes to decline with age, the rate at which our body’s decline is impacted by many controllable lifestyle factors such as how we eat, how we move, and how many toxic substances we are exposed to.
