We support federal, provincial and local public health authority recommendations that promote the health of Canadians.
We encourage early intervention with integrative medicine therapies and consultation with integrative medicine physicians and other healthcare professionals. This is particularly relevant when there are limited conventional therapies that can be recommended to patients.
We hold that informed consent, without coercion, is essential for all medical treatments and procedures including integrative medicine options.
We encourage all lifestyle measures that reduce the risk of infection and, if infected, increase the likelihood of rapid and full recovery. These include access to shelter, good food, adequate sleep, sufficient fluid intake, fresh air, exercise, interaction with friends, relatives and community, exposure to nature, smoking cessation, and moderation of alcohol intake.
We emphasize the importance of psychological wellbeing, particularly with quarantine and social distancing protocols. Activities such as yoga, mindfulness training, dance, music, social interaction at a distance, and prayer are known to reduce stress emotions such as fear, anxiety, anger, despair, and depression.
We identify psychological counseling and support as essential for ameliorating the mental and emotional trauma that some people are experiencing during this pandemic and the resultant social isolation protocols.
We recommend nutritious food. We also encourage the use of supplements to both improve health generally and to increase resistance to viral infections, as per the current recommendations of the International Society for Orthomolecular Medicine (ISOM)1-25 and in accord with the Institute for Functional Medicine 26.
We emphasize the importance of vitamin D3 and vitamin C supplements in the elderly population and residents of Care Homes in Canada because of the absence of sun exposure and poor nutritional status in this population.
We recommend that healthcare providers and hospital staff, who have increased risk of exposure to SARS-CoV-2, be provided with nutritional supplements to enhance their resistance to infection and inflammation.
We recommend baseline serum 25-hydroxyvitamin D3 testing for all patients in long-term care and for anyone admitted to hospital in order to determine if vitamin D3 deficiency is a contributing factor to severe COVID-19 infection and to gauge the need for supplementation.
We support the current recommendations of ISOM for optimizing immune function for all Canadians, with modifications for children. For adults, these recommendations are:
- A minimum of Vitamin C 500-1000 mg 1-3 times daily. This dose can be increased to bowel tolerance* to optimize prevention and support treatment of active infection.
- Vitamin D3 4000 IU daily from October to May, with serum 25-hydroxyvitamin D testing to ensure a level of 100–150 nmol/L.
- Canadians should continue vitamin D3 supplementation year-round if they have inadequate sunshine exposure in the summer months. This is likely to occur in office workers, the elderly, and skin cancer patients (who are avoiding sun exposure).
- Zinc 20 mg daily. This is often contained in a good-quality multivitamin.
- Magnesium: Start with 50-100 mg daily and increase to bowel tolerance* (preferably magnesium bisglycinate). Caution: If you have any kidney disease, consult your healthcare provider before starting Mg.
- Selenium 100 mcg daily
[*bowel tolerance: increase dose until loose stools, then reduce dose slightly to maximize intestinal absorption.]
We support the early use of “low risk – high benefit” therapies for treating suspected or confirmed Covid-19 patients. At this time, these therapies include:
- High dose intravenous vitamin C at sufficient doses to be effective (from 12 gm/day to 1.5 grams per kg/day). [Recommendation based on best-available evidence, biological plausibility, low risk, and based on clinical experience of ICU physicians]
- In some cases, oral dosing may be adequate.

- Nutritional supplementation. [Recommendation based on best available evidence, biological plausibility, and low risk]

Hydroxychloroquine27 and zinc, with or without azithromycin should be considered, based on best-available evidence and ongoing clinical trials. Zinc becomes a powerful anti-viral agent after it is carried into cells by transporters, like hydroxychloroquine, where it disrupts viral replication.
We recommend frequent review of the use of conventional medications known to increase susceptibility to pneumonia and respiratory failure through various mechanisms, such as suppression of respiration and immunosuppression.27 This is particularly important for elderly patients.
We advise minimizing the use of anti-fever drugs, such as acetaminophen (Tylenol), ibuprofen (Advil), and aspirin, for mild-moderate fever29. Most viruses are temperature sensitive and fever is considered to be a component of the body’s defence response. We recommend caution using anti-inflammatories, such as ibuprofen, in Covid-19 disease.30,31
