Coronavirus & IBD: Vitamins & Supplements
Should IBD Patients be taking vitamins, minerals, or supplements to help avoid becoming infected with SARS-CoV-2?
There are lots of questions about the novel coronavirus (SARS-CoV-2) and whether vitamins, minerals or supplements may help IBD patients avoid infection with the virus. In addition, people wonder if complementary approaches could help shorten or lessen the course of COVID-19. First and foremost, supplements should NOT replace medications, healthy diet, hydration, hand washing, and social distancing. There is currently no evidence supporting use of supplements including vitamins and minerals to prevent or treat infection with SARS-CoV-2. We hope the information below will help you, your family, and healthcare team discuss the current evidence related to COVID-19 and vitamin, minerals and supplements.
It’s important to stress that the decision to add complementary therapy approaches should be integrated and done in consultation with your healthcare provider. Every IBD patient is different, on different medications, and what’s right for one person may not be appropriate for another.
Know the facts: new treatments or therapies
The web is full of information and recommendations. Some information is written by experts, others by social influencers and the media. Sorting through this information and understanding what’s being researched vs. what is safe to use can be difficult. Now, with the rise of this pandemic comes those who are looking to profit off the fears of the masses through promoting “treatments” or “cures” that lack evidence and may possibly even cause harm. Any recommendation found on TV, on a website, or in social media should be discussed with your healthcare team. Click here to read more about complementary medicine.
Supplements and SARS-CoV-2
There is currently no evidence supporting use of supplements, including vitamins and minerals, to prevent or treat infection with SARS-CoV-2.
There are a few supplements that may support the immune system. The information below focuses on vitamins, minerals and other oral supplements and the research supporting use. Please note this is general immune support information. There are no studies currently available that demonstrate effectiveness of these supplements to support those infected with COVID-19.
As you review this information, please note that supplements can be marketed without approval of the FDA, which means claims about effectiveness are largely unproven (unlike the large randomized controlled trials required for FDA-approved medical therapies). Label claims that products are safe and effective may not be entirely accurate.
Before taking any supplements, including the ones below, please discuss the risks and benefits with your healthcare provider. You can learn more about evaluating risk and benefits of complementary medicine by visiting the Foundation’s Complementary Medicine resources: Risks and Benefits.
Lastly, Crohn’s disease and ulcerative colitis, collectively known as inflammatory bowel disease (IBD), are conditions of an overactive immune system. Boosting the immune system is not currently recommended, nor are available supplements proven to improve immune function. At this time there are no studies, or recommendations from IBD experts, to support supplements to prevent infection with SARS-CoV-2.
Adequate levels of micronutrients are important for preventing infection, supporting immune function, and maintaining health. Patients with IBD are at an increased risk of vitamin and mineral deficiencies, therefore, levels should be monitored on a routine basis and deficiencies should be corrected as needed. Long-term supplementation of certain nutrients (e.g. zinc) can decrease absorption of other nutrients (e.g. copper) and may cause harm, Always discuss supplement use with your healthcare provider.
While this is not an exhaustive list of supplements, these are the ones most commonly asked about by IBD patients. Your friends, family and the web may recommend a number of other supplements for preventing or easing the symptoms of an infection, but it is important to understand the research and evidence (or lack of evidence) to support such approaches.
IBD patients and caregivers are strongly encouraged to do research on any supplement they are interested in discussing with their healthcare team. There are lots of products on the market with claims to be remedies for COVID-19 or to be protective against the coronavirus. To this end, the FDA has issued warning letters to manufacturers making coronavirus claims. To learn more visit the FDA News Release: Coronavirus Update.
Please be careful as some of the products being promoted as “miracle” solutions can be - and have been - shown to be harmful.
