It’s that time of year when sickness lurks around every corner. For those of us who are immunocompromised, run of the mill “regular people” sickness can hit us extra hard. Since the end of September, I’ve dealt with bronchitis for 5 weeks, followed by pink eye in both eyes, and I currently am dealing with a bacterial infection in my right eye. Being an IBD mom with young kids in preschool and elementary school brings extra germs into our house. While I’ve been under the weather, I keep second guessing what supplements are deemed “safe” and beneficial for me to take since I’m on a biologic. Even 18-plus years into the game, I still get confused about the gray area around supplements to help us improve or boost our immune systems and which we need to be careful of.

This week on Lights, Camera, Crohn’s we hear from three gastroenterologists who take a deep dive into this topic, along with a registered pediatric GI dietitian, and several people from the patient community. Before we get started, I want to preface this by saying this is a complex issue that is not black and white. Even after digging deep researching this topic—I’m still not completely clear on what’s best for myself.

There’s been conflicting beliefs on whether Elderberry is “smart” to take when you’re immunocompromised. I ran a poll on Instagram asking our community what they’ve been told. Of the 260 people who responded 72% said “This is a thing?!”, 21% of those polled said they were told to “Steer clear when on immunosuppressants”, and 7% of people were told by their provider that it’s “Safe and advised” to take Elderberry.

Let’s hear what patients have to say

Samantha: “I was advised not to boost my immune system. So, I focus on nourishing my body well when sick. I drink a lot of smoothies and fresh juice. I’d avoid Elderberry for sure. I take daily vitamins and get my levels checked regularly to make sure I’m getting enough of what I need. However, I have a kid in school who brings all those lovely germs home. I had a GI once explain it to me like this…my immune system is overactive; I have to take medication to weaken it, which brings it down to a “normal” range. If I try to “boost” it, I’m working against my medication.”

Cindy: “My mother-in-law purchased some Elderberry for my daughter with Crohn’s shortly after her diagnosis. “A woman at Whole Foods told me this could be good for her.” She meant well. Anyway, I understood that my daughter shouldn’t take Elderberry, after consulting with Dr. Google. I believe it was a reputable website that contraindicated Elderberry for patients on immune suppressing medications.”

Emily: “I have been told both—that Elderberry is safe and that it is not. My family doctor told me to avoid it and my GI nurse says that it’s ok sometimes when sick?! So confusing!”

Alyssa: “My husband has Crohn’s and is on Entyvio. He takes Elderberry if he has flu or cold symptoms, whereas I take it daily during the winter. Funny enough, I’m sick A LOT more than him!”

Jessie: “I’ve been told by some doctors not to take immune boosting supplements with biologics and others that it doesn’t matter, but I can’t find the concrete research/facts I need to be sure.”

Lindsey: “I find my symptoms flare when I have Elderberry!”

Rachel: “I’m always confused if I should be taking anything to “boost” my immune system when I’m on suppressive meds. I asked my provider years ago, but I didn’t really get a real answer. I’ve always thought it was good to take supplements to help my immune system, but then I get concerned about them counteracting my medication.”

Hermione: “I have been told it is a placebo effect by my immunologist.”

Kristen: “I read that you don’t want to boost your immune system since that’s the system you want suppressed and caused your disease in the first place.”

Bee: “I was told not to take things that will “boost” the immune system. In South Africa, it’s Echinacea. I was told not to take it. So, my approach has been to “indirectly boost” my immune system by taking vitamins and fresh fruit and vegetables as much as I can tolerate.”

Rocio: “I’ve had this conversation with providers, particularly when I had COVID. I was told NOT to take Elderberry because it has been shown to increase cytokine storm which is present in both COVID and IBD. From an IBD specific point of view, the anti-TNFs seem to calm that storm which is why some were used as COVID therapeutics. So, I wouldn’t say it’s because of being on immunosuppressants, but rather the disease itself.”

Julie: “I live on Elderberry but never asked my doctor, so I’m hoping it’s ok!”

Laura: “I’ve taken Elderberry for years on Remicade (also working as a nurse practitioner in pediatric primary care) and it has helped keep me well and my GI docs have never been opposed to me taking it. I do usually skip it the night before and after an infusion though.”

Jana: “I was told it could cause increased risk of cytokine storm for those with IBD in general, whether on immunosuppression or not.”

Heather: “My son’s GI said NO to Elderberry. We used to take it every winter, but once he was diagnosed with Crohn’s they said to stop using it. I always worry about this time of year and all the yucky stuff going around. My son takes the Liquid IV Vitamin C packets and puts those in his water. I don’t know if they help, but I feel better knowing he is taking something to maybe help give him a boost!”

Beth: “I’m so glad you’re covering this because there is so much confusion—should we try to boost our immunity or not? My personal experience is that I was taking it trying to boost my immunity before a busy event season when I needed to stay healthy. About three weeks later, I was wracking my brain trying to figure out what was flaring my Crohn’s because I’d been eating right, sleeping more, hydrating…and I think it was the Elderberry. In general, I have tried to shift my logic to “these are things that help keep me healthy” versus “how do I boost my immunity?”

Madison: “My first GI told me “No” if you’re on biologics. Not sure if that’s true, but I just trusted that guidance and still avoid it!”

Jess: “I was told to steer clear of Elderberry because of having IBD.”

Jaclyn: “I have asked so many times what I can take, and I’m always told there is basically nothing extra I can do. I have a 4-year-old and 5-month-old in daycare, so they are always bringing home sicknesses.”

Elderberry: To take or not to take?

After reading those firsthand experiences it’s clear—the patient population is unclear and hesitant about what is best when it comes to boosting immunity. While Elderberry has gained popularity for its potential immune-boosting properties, its safety for those of us with IBD is not well-established. Elderberry supplements are often promoted for their antiviral and immune-enhancing effects, primarily attributed to compounds like flavonoids and anthocyanins.

Before I became a patient advocate, I would take elderberry anytime I felt a sniffle or had a sore throat. I really felt like it made a positive difference. Fast forward a few years and I started hearing that Elderberry could interact with Humira and cause my immune system to become over-active, so I stopped taking it all together. To this day, I wonder about taking it—and I know many of you do, too!

There are a few considerations for those with IBD when it comes to Elderberry:

Sorbitol Content: Elderberry products, particularly some syrups and extracts, may contain sorbitol, a sugar alcohol. Sorbitol can have a laxative effect and may exacerbate symptoms for those with IBD, especially if you are sensitive to sugar alcohols.

Potential Interaction with Medications: Elderberry may interact with certain medications or treatments for IBD. Elderberry is believed to have immune-modulating properties. When taken with immunosuppressive medications like Humira or Remicade, there is a potential risk of enhancing the immunosuppressive effects, which might increase the susceptibility to infections. It’s important to discuss this with your healthcare provider to understand the potential implications.

Limited Research: There is limited research specifically addressing the safety and efficacy of Elderberry in individuals with IBD. The specific interactions can vary, and it’s essential you ensure there are no adverse effects or diminished efficacy of your prescribed medications.

The GI’s weigh in on the debate

Dr. Miguel Regueiro, M.D., Chief, Digestive Disease Institute, Cleveland Clinic, says that while he does not want to sound dismissive of supplements, that we lack good data to make claims for or against. Personally, he does not feel Elderberry is harmful, and does not have a problem with his patients taking it.

“I am not aware of good, randomized data to indicate true harm from Elderberry in immunosuppressive or immunomodulatory medications, even though there are warnings listed,” he said. “Theoretically, Elderberry will “stimulate” or “activate” the immune system and has been a popular supplement that some recommend for “cold/flu” or to prevent cold and flu.  If that theory is true, then potentially elderberry as an immune stimulant would offset or counteract an immunosuppressive.”

Without good, randomized safety data, it is difficult to make this strong claim one way or another. Given that Elderberry may or may not help with cold/flu, in an abundance of caution it would be reasonable to avoid in patients on immunosuppression. 

“My sense is that the dose of Elderberry is low enough that even with immunosuppression, there should not be a problem, but, again, without confirmatory evidence to say that Elderberry effectively “fights off” or “prevents” cold/flu, one could simply avoid it in patients who are immunosuppressed.”

Dr. Regueiro says the ideal health-related approach is to ensure that IBD patients are eating a whole food diet, avoiding processed/ultra processed foods, drinking plenty of water each day (1-2 liters), exercising regularly, and having good sleep hygiene.   

“Regarding additional supplements, based on a patient’s history and certain IBD meds, we recommend different supplements. For example, for patients who have been on steroids in the past, we recommend a bone densitometer for osteopenia (and osteoporosis). If bone mineralization is low, we recommend supplemental calcium and Vitamin D.  If a patient has had ileal (small bowel) surgery, we will check a vitamin B12 level and if it’s low, we recommend parenteral (subcutaneous) shots, as they will not be able to absorb oral B12.”

He went on to say that iron levels should be checked, as iron deficiency is common. If iron levels are low and a patient is anemic, parenteral (IV) form of iron is recommended, as oral iron can upset the stomach and even lead to more IBD symptoms.

“For patients with short bowel syndrome from extensive bowel surgery, they should be managed by a nutrition team who specializes in short gut as the evaluation of nutrients and  vitamins is more comprehensive and detailed. Finally, for most of our IBD pts who do not have any of the above vitamin deficiencies, as long as they’re eating a well-rounded, healthy diet, they need no other vitamins. However, I tell my patients that taking a once per day over the counter vitamin is generally safe and ensures all nutrients are covered.”

Dr. Yezaz Ghouri, M.D., Director of Inflammatory Bowel Disease Services, University of Missouri School of Medicine at Columbia, says elderberries seem to have high amounts of antioxidants.

“The main antioxidant seems to be a bioflavonoid called Anthocyanin. These give purple pigment in the berries and have powerful antioxidant properties. Antioxidants have an anti-inflammatory and anti-carcinogenic effect in the body. Patients with IBD have chronic ongoing inflammation and are at increased risk of developing colon cancer. Carcinogenesis refers to the conversion of normal tissues to cancer. In general, we recommend the use of berries in IBD patients, and these are a good source of minerals, vitamins, and healthy carbs. The Crohn’s and Colitis Foundation cautions the use of Elderberry in IBD patients due to concerns that this fruit increases production of certain types of chemicals in the body that can cause IBD type inflammation. One of these chemicals is called tumor necrosis factor (TNF), the same which is blocked by medications used to treat IBD.”

Immunosuppressive medications and antioxidants work hand in hand in preventing inflammation.

“But there have been some studies that showed the effect of Anthocyanins on a group of immunosuppressive medications used in IBD called anti-TNF alpha inhibitors (examples: infliximab, adalimumab, certolizumab, golimumab). There is inconclusive evidence in this matter and there are no large clinical human studies showing that use of Elderberry is linked with an effect on TNF alpha inhibitors ,” explained Dr. Ghouri. “Please consult with your GI specialist prior to their use. Taking Elderberry in moderation should be ok, but if one develops any signs of disease flare, then stop the use,” he said.

Dr. Ghouri agrees that it is “ok” for IBD patients to take Elderberry.

“Elderberry has very strong anti-inflammatory properties that may contribute towards preventing damage from chronic ongoing inflammation and free radical based tissue injury.” 

Dr. Ghouri recommends the following protocol for labs to indicate whether you need specific supplements/vitamins added to your regiment:

• Checking Vitamin D levels at least once a year
• Checking Vitamin B12, Folic acid and Iron (Ferritin) levels, if anemic
• Specifically checking Vitamin B12 level once every 6 to 12 months in patients with Crohn’s disease involving the small bowel

Checking other mineral or vitamin levels may be patient dependent, please check with your GI specialist or PCP. There is a need for checking vitamin and mineral levels more frequently in patients who have lost most of their small bowel, due to Crohn’s disease. These individuals have a diagnosis of short-gut syndrome and sometimes require IV nutrition. These patients are at higher risk for developing all sorts of vitamin and rare mineral deficiencies. They need to be seen by a specialist with a background in managing such patients and require frequent blood testing for several minerals and vitamins.

The Pediatric Perspective

With young people often being the carriers of so many germs and being susceptible as school age kids—I wanted to hear from Dr. Michael Dolinger, M.D., MBA, Assistant Professor of Pediatrics, Associate Pediatric Gastroenterology Fellowship Program Director, Icahn School of Medicine at Mount Sinai.

“For any patient on immunosuppressive medications, it is important to have an open discussion with your treating gastroenterologist about Elderberry, specifically Sambucus nigra, which is used in most herbal supplements. This could stimulate the production of components of the immune system that cause inflammation, mainly cytokines and tumor necrosis factor,” explained Dr. Dolinger. “Many effective therapies target these cytokines or tumor necrosis factor to treat inflammatory bowel disease, as they are often elevated. There is no clear evidence to support this either way, but if you are on a therapy that targets tumor necrosis factor or cytokines for your inflammatory bowel disease, I would certainly have a discussion with your gastroenterologists to review the potential risks and benefits first.”

He went on to say that one of the largest issues with using supplements, particularly in children, is that they are not regulated by the Federal Drug Administration, and you have no way of knowing if what is on the label is in the supplement you would be giving your child.

“I always encourage parents who are thinking about giving supplements to children to assess if there have been any studies of this particular supplement in children or ongoing studies and if not, I urge them to use the same caution they have surrounding any therapy and that is to place safety at the forefront and not give unregulated supplements to children,” said Dr. Dolinger.

For children with IBD, a well-balanced diet with adequate calories for growth and development is the most important recommendation. Supporting supplementation with iron, vitamin D, vitamin B12, and calcium is needed when these levels are low.

“Routine monitoring of vitamins and micronutrients is essential in the care of inflammatory bowel disease patients. For example, vitamin C deficiency often goes unrecognized. We see zinc or selenium deficiencies not uncommonly too. It is most important to have routine monitoring for vitamins and micronutrients at diagnosis and when doing well, at least yearly,” he said.

Erin Feldman, R.D., CSP is a pediatric dietitian. She looked up Elderberry on a database called NatMed. Here’s what she found:

“On the natural medicine database, under “interactions with drugs” immunosuppressants are listed and it states—theoretically, Elderberry might interfere with immunosuppressant therapy, due to its immunostimulant activity. Elderberry has immunostimulant activity, increasing the production of cytokines, including interleukin and tumor necrosis factor. On the patient handout it states that Elderberry might cause the immune system to become more active. This could increase symptoms of autoimmune diseases. If you have one of these conditions, it is best to avoid Elderberry.”

Supplements and Lifestyle Choices that may offer general immune support

If you plan to incorporate any supplements into your routine, please consult with your care team, preferably a gastroenterologist or a registered dietitian, who is familiar with IBD and how it manifests in our bodies. Here are some different supplements you may want to check out:

Probiotics: Probiotics are beneficial bacteria that can help maintain a healthy balance in the gut microbiome. Some studies suggest that certain probiotics may be helpful for individuals with IBD, but their effectiveness can vary. Different strains may have different effects, so it’s crucial to consult with a healthcare professional before using probiotics.

Vitamin D: Adequate levels of vitamin D are important for overall health and immune function. Many people with IBD may have lower levels of vitamin D. This can be determined by a simple blood test. I personally have been vitamin D deficient for years, so I’m prescribed 50,000 IU a week right now.

Omega-3 Fatty Acids: Omega-3 fatty acids, found in fish oil, flaxseed oil, and certain nuts and seeds, have anti-inflammatory properties. They may help support the immune system and reduce inflammation. Again, consult with your healthcare provider for appropriate dosages.

Zinc: Zinc is essential for immune function. Some people with IBD may have lower levels of zinc, so supplementation may be considered under the guidance of a healthcare professional.

Turmeric/Curcumin: Turmeric, and its active compound curcumin, have anti-inflammatory properties. Some studies suggest that curcumin may have potential benefits for those with IBD, but more research is needed. It’s essential to consult with a healthcare provider before using curcumin supplements.

Quercetin: Quercetin is a flavonoid with antioxidant and anti-inflammatory properties. It is found in various fruits and vegetables. Some studies suggest it may have potential benefits for individuals with IBD, but more research is needed.

Lifestyle Factors: Adequate sleep, stress management, and regular exercise are crucial for overall health and immune function. Ensure you are getting enough rest and engaging in stress-reducing activities.

Final Thoughts

Given the potential for interactions and the need to manage the delicate balance of the immune system in individuals with IBD, it is highly advisable to consult with your healthcare provider before adding Elderberry or any new supplement to your routine. A lot more research is needed in this field to better understand supplements and their effects on medications.

There is no clear evidence that immune boosting supplements such as elderberry produce cytokines and tumor necrosis factor to counteract medications, but there is also no strong evidence that they do not either. We don’t know the way in which supplements support or do not support individual immune systems in patients with inflammatory bowel disease on therapies that target the immune system.

Your healthcare provider may guide you on whether elderberry or other immune-supportive supplements are appropriate for you, and if so, what dosage is safe. Always follow their recommendations to ensure the best possible outcomes and to minimize the risk of complications.
