Can Immune Support Supplements Help Fight Cancer?

Hiya Gorgeous!

Getting the daily nutrition we need can be challenging for many reasons (both in and out of our control). Even the most vigilant health enthusiasts can have nutritional gaps in their diets. And when you add a cancer diagnosis to the mix, it’s even more important to identify the missing pieces that can support our overall well-being, recovery and longevity.

That’s where quality supplements come in. The right kinds of supplements are like targeted wellness support, designed to address those gaps and cover the bases so we can thrive.

Supplements are an important part of my own wellness practice, but there’s a lot of uncertainty surrounding the supplements industry.

• Can you trust the manufacturer?
• Are the ingredients high quality?
• Are all the ingredients plant-based?
• Do they include enough of the active ingredient to actually support your health?

The questions multiply for the cancer patients in our community (myself included!).

• Should cancer patients take immune support supplements?
• Are there any interactions with cancer treatments to be concerned about?
• Can supplements actually help you fight cancer?

To provide some much-needed clarity, I’ve invited my brilliant friend, Lizabeth Gold, to join us today. She’s a Registered Dietitian at the Block Center for Integrative Cancer Treatment.

She’ll share the risks we need to know about, then detail 5 ways supplements can help cancer patients (and 6 types you should explore).

I’ll let Liz share her brilliance with us now.

Can Immune Support Supplements Help Fight Cancer?

There’s some controversy around supplements for cancer patients.

After so many years of research and clinical trials, it’s hard to believe there isn’t more of a consensus in the healthcare community regarding supplements and the role they play in immune support for patients.

Opinions still vary widely among doctors with many conventional oncologists discouraging supplements altogether. Their main concern is whether certain supplements will interfere with treatments or radiation. Others are just unsure what to recommend, so they take an ultraconservative approach.

It’s important to remember that many of these doctors are experts in their particular specialty for a reason—they focus all of their attention on knowing and understanding the disease they treat and, of course, that’s a good thing! Keeping up with the latest developments in the ever-progressing world of cancer is a huge challenge all by itself.

I can understand why it might not be a priority for them to try and sift through all of the latest research from the supplement world. Admittedly, conflicting information does exist and new information from clinical trials is continuously changing what we know about supplements and their role in immune support for cancer patients.

Are There Any Risks to Consider?

Yes, sometimes.

• The FDA doesn’t regulate supplements in the same way it regulates prescription drugs, which is not surprising since the supplements industry is so vast. The FDA will pull a product off the market if it is found to be misbranded or adulterated, but it might be after those contaminants have already harmed someone.
• Some manufacturers make unsubstantiated claims about the benefits of their supplements so consumers don’t always get what they pay for. This may be especially true when wondering whether a supplement can actually help cancer patients.
• There are certain supplements that cancer patients should avoid altogether. For example, high doses of beta carotene, a form of Vitamin A, is associated with higher risk of lung cancer progression in men who smoke and a recent study found that patients taking probiotics were less likely to respond to immunotherapy. St. John’s Wort is a good example of one supplement that all cancer patients should avoid as it interferes with several common drugs and can produce serious side effects. Although not definitive, a study done in 2009 in mice found that green tea may interfere with Velcade, a drug used to treat Multiple Myeloma and Mantle Cell Lymphoma.
• Research is sometimes sparse regarding interactions between supplements and some of the newer cancer drugs, making it difficult to evaluate safety. In these cases, the decision to take a supplement or not, requires a deep understanding of the mechanism of action of both the drug and the supplement. Sometimes it might also be necessary to weigh the benefits (and quality of life) against potential risk.

It is critical that every patient work with someone they trust to create a supplement regimen tailored specifically for their individual needs as they fight cancer.

These recommendations should take into consideration their particular disease, type of therapy, medications, side effects, stage of cancer, tumor histology, nutritional deficiencies, labs, and overall goals. A well-rounded regimen should include agents that help decrease inflammation, provide immune support, display anti-cancer properties, and address side effects and nutritional deficiencies. Let’s unpack each of those in greater depth now.

5 Ways Supplements Can Help Cancer Patients

Benefit 1: Reduce Inflammation

Chronic and unresolved inflammation is linked to cancer growth and progression. Plus, chemotherapy and radiation can make inflammation worse. Boswellia, scutellaria, green tea, omega-3 fatty acids from algae oil, curcumin, and alpha lipoic acid can all help cancer patients control inflammation.

Benefit 2: Nutrient Support

Nutritional deficiencies are common among cancer patients due to various side effects such as nausea, pain and loss of appetite. Vitamin D deficiency is found in about 75% of cancer patients and Vitamin D deficiency is linked to advanced forms of cancer. Simple vitamin and mineral supplementation can improve quality of life, deter weight loss, and help prevent treatment delays. Zinc, iron, Vitamin C, Vitamin D, potassium, CoQ10, magnesium, and B vitamins often appear at low levels in patients with advanced cancer and should be tested. A high-quality multivitamin may be all you need to get to optimal nutrient levels.

Benefit 3: Anti-Cancer Effects

Although highly debated, real data does exist regarding various compounds and their impact on the cellular pathways that contribute to cancer growth and progression. One good example, Indole 3-carbinol (the same compound found in cruciferous vegetables), is a known regulator of estrogen metabolism and signaling pathways in breast cancer. Curcumin, resveratrol, quercetin, green tea, and melatonin, among others, have been extensively studied for their modulatory effects that can support your body as you fight cancer.

Benefit 4: Immune Support

Breakdowns within our very complicated immune system play a big role in cancer initiation and proliferation. Our immune system is constantly working to fight cancer, and experts believe that if we didn’t have an immune system, every person would end up with cancer of some form. Advancements in drugs aimed at the immune system (immunotherapies) are significantly improving outcomes in deadly cancers like non-small cell lung cancer, kidney, and some melanomas. Immune support supplements like medicinal mushrooms, beta glucans, Vitamin D, zinc, antioxidants, flavonoids, resveratrol, and fiber may help strengthen several immune pathways.

Benefit 5: Reduce Side Effects

Many of the supplements mentioned above can also be used to reduce side effects like fatigue, brain fog, neuropathy, diarrhea, constipation, insomnia, and general malaise. They can help cancer patients enjoy a higher quality of life while undergoing treatment.

Yes, Supplements Can Help Cancer Patients

Altogether, the research demonstrates that supplements deserve a place in cancer support. But again, regimens should be customized and carefully monitored by someone with experience.

Never take supplements that claim to “cure cancer” and be skeptical of anecdotal evidence where one or two people make unsubstantiated claims about a product. Randomized, controlled trials in humans are the most reliable evidence, but even these types of studies can be conducted improperly. Before taking any supplement, you should always review all supplements with your entire medical team to check for safety.

Now you’re likely wondering, “What are some specific supplements I should explore and how can they support me?”

6 Types of Supplements That May Help Cancer Patients

Type 1: Vitamin D

This is one vitamin supported by a lot of research. A large number of population-based studies and randomized, controlled trials found Vitamin D is able to slow or control the growth of various types of cancer cells by stimulating cancer cell death, promoting cellular differentiation, and reducing the supply of blood vessels to tumors. Vitamin D also plays an important role in regulating and controlling inflammation, and providing immune support. Cancer patients are often noted to have lower circulating levels of Vitamin D in their blood and many drugs can damage bone health making this one of the most important supplements in your regimen. Since Vitamin D is a fat-soluble vitamin and can build up over time, it’s important to get your Vitamin D levels tested regularly to make sure your dose is just right for you.

Type 2: Multivitamins

A healthy, whole food, plant-based diet is one of the most important things you can do to take care of yourself during your cancer journey. But certain conditions or drugs can cause loss of appetite and taste changes, along with nausea and pain, making it difficult to get every nutrient necessary for optimal health. Choosing a good multivitamin is key to filling in those gaps.

Look for a multivitamin that is potent, pure and third-party tested for toxins and heavy metals. If someone is iron or copper deficient, it is best to take these minerals separately in only the amount necessary to get back to optimal levels. As well, look for one that contains B vitamins in their “active” form* and in reasonable amounts. Try to avoid folic acid, a form of folate, unless specifically prescribed by your doctor.

• *Active form of B9 (Folate): 5-Methyltetrahydrafolate
• *Active forms of B12: Methylcobalamin or Adenosylcobalamin

Type 3: Omega-3 Fatty Acids

A potent anti-inflammatory, omega-3 fatty acids provide additional nutritional support and help cancer patients address the side effects from chemotherapy. Various randomized, controlled trials found that patients taking supplemental fatty acids experienced less peripheral neuropathy, stomatitis, and diarrhea. There are currently several clinical trials to assess how omega-3s can address various other cancer-associated complications such as cachexia (muscle wasting), pain, and depression.

Type 4: Turkey Tail and Reishi Mushrooms

Turkey Tail (Coriolus) and Reishi (Ganoderma) mushrooms are known for their immune boosting properties. Because medicinal mushrooms are traditionally used in the practice of Eastern medicine, the most comprehensive studies come from China or Japan. The National Institute of Health conducted a clinical trial among breast cancer patients and found that Turkey Tail “increased natural killer cells and other cancer-fighting cells in the immune system”.

Both Reishi mushrooms and Polysaccharide K (PSK), the active compound in Turkey Tail, were studied in various trials of breast, gastric, lung, and colorectal cancer and found to have several benefits such as improved immune function and overall well-being, as well as a reduction in tumor size and a higher survival rate. That means these supplements can both offer you immune support and help your body fight cancer.

Mushrooms and mushroom supplements, if sourced properly and safely, are generally very well tolerated with no apparent side effects. Other mushrooms like Shiitake, Maitake, and Cordyceps are also beneficial, although the research is less robust.

Type 5: Green Tea

Green tea contains the polyphenol/catechin EGCG and is considered a powerful antioxidant and chemopreventative agent. Significant research has documented the suppressive effects of EGCG in various cancers including breast, colon, lung and prostate through the regulation of cancer signaling pathways.

Some doctors fear antioxidants will interfere with the efficacy of certain cancer treatments or radiation and recommend avoiding green tea completely along with all other antioxidants like Vitamin C and CoQ10.

In reality, there’s not a lot of evidence proving that antioxidants interfere with treatments at all. If your doctor doesn’t like the idea of green tea during treatment, she might be open to allowing it on the days in between cycles, so don’t be afraid to ask.

Type 6: L-Glutamine

This is perhaps the best supplement available for gastrointestinal side effects and neuropathy.

An important building block for protein in the body, L-Glutamine is the major fuel source for cells that line the gastrointestinal tract and are necessary for optimal immune function. It can be helpful for several side effects caused by chemotherapy such as mucositis, gastrointestinal toxicity, muscle wasting, neuropathy, and diarrhea.

A small study conducted in 2010 suggested that tumor cells exhibit “glutamine addiction” and that taking glutamine in excess may contribute to cancer growth and progression, but follow-up studies found conflicting results. Until further research is conducted, it is recommended that patients take L-Glutamine only on the days right before, during, and after treatment just to be cautious.

Final Notes for Evaluating Supplements for Cancer Support

Investigate and Research Your Supplements

• Are you able to easily contact the company for information about their product?
• Look for good manufacturing processes and the symbols below.
  
• Buy organic and vegan when you can. Make sure to check the label and ingredient list for allergens like soy or nuts and unhealthy fillers like maltodextrin.
• Be especially careful with herbals and imported supplements. Only buy reputable brands.
• Buy from companies that are transparent about where they source their ingredients. If they don’t tell you where it comes from, it might mean they have something to hide.
• Check for expiration dates. Supplements are less effective when their date is passed.
• Never buy a supplement that promises to “cure cancer” or claims to be a “breakthrough” or “miracle”.
• Avoid complex mixtures of ingredients as these are generally of low value and have potential to cause more harm.
• Always incorporate supplements slowly and watch for negative side effects.

Don’t Forget About Healing Foods!

Certain foods can also help fight cancer. Here are some to consider:

• Fresh Ginger: A miracle worker when it comes to nausea, ginger can be added to smoothies to soothe the tummy and aid in digestion. A great recipe to try is 1 cup of rice milk, 1 cup of frozen peaches and a chunk of fresh ginger.
• Garlic: Garlic contains a biologically active compound called allicin that has anti-cancer, anti-inflammatory properties. Note that garlic is also a known blood thinner and should be avoided in large amounts when undergoing surgery or taking blood-thinning medications.
• Prebiotic Foods: Fermented foods like miso, kimchi and sauerkraut, plus root vegetables like jicama, chicory root, onions, carrots, and sunchokes help to diversify the gut microbiome and provide immune support.
• Cruciferous Veggies: Broccoli sprouts, cauliflower, cabbage, kale and bok choy all contain sulforaphanes and glucosinolates believed to have anticancer, antioxidant properties.
• Green Tea: Drink plenty of green tea for all the reasons shared above!
