There are literally thousands of nutritional supplements out there in the world that claim they are the absolute best for this or that. I have tried a LOT of them over the past decade since originally being diagnosed with breast cancer – and prior to that as well. I have done a lot of reading, researching for myself and others, and asked a lot of questions of experts, all in an effort to sort out what actually does make a difference when going through breast cancer. And because it’s just as important, what will help you stay well in the long run. Here’s my list of the absolute best ones.
- American ginseng (Panax quinquefolius) – A tonic herb utilized by Native American peoples for hundreds of years, it is a good immune booster, helps with energy levels, and decreases recovery time post-surgery. A 2015 American study found that two of the phytochemicals in American ginseng, ginsenoside Rg3 and compound K, inhibited angiogenesis, the ability of cancer tumor cells to create new blood vessels to feed themselves. They also induced cancer cell apoptosis, or planned cell death, which is missing in cancer cells.  This is a good brand.
- Andrographis (Andrographis paniculata) – Studied recently for its immune stimulating and anti-inflammatory benefits. 2016 research from India also indicates it may be good for breast cancer. Researchers stated that the phytochemical andrographolide induced apoptosis in triple negative breast cancer cells but protected normal breast cells.  I like to take it in tincture form, this is a good brand.
- Ashwagandha (Withania somnifera) – An Ayurvedic herb useful for strengthening the immune system, it also combats the effects of stress, reduces anxiety and depression, and has anti-inflammatory benefits. Again, we have new research indicating it may have applications for breast cancer as well. The journal Molecular Immunology published a research paper by Chinese scientists dated January 2017 that indicates one of the phytochemicals in ashwagandha, withaferin A, induces apoptosis in triple negative breast cancer cells and also prostate cancer cells.  Here is a good brand, and it’s organic.
- Astragalus (Astragalus membranaceus) – Used for centuries in traditional Chinese medicine, astragalus is a potent enhancer of the immune system. There are now dozens of studies which also attest to the anti-cancer properties of astragalus in many different cancer cell lines, including estrogen receptor positive AND negative breast cancer cells. I’ve listed just one of the studies at  below. This is a good, organic one.
- Curcumin – One of the top ten anti-cancer nutrients, it is a yellow pigment derived from the root spice turmeric, a powerful antioxidant. We have dozens of research studies on its anti-cancer activity, and it also decreases the levels of two enzymes in the body that cause inflammation.  Because it is rather poorly absorbed, the best way to take curcumin is via supplementation because combining it with certain other nutrients helps to make it more bio-available. By all means, eat the fresh root too, but if you are depending upon it for your wellness regimen, supplementing with curcumin is more controllable and therapeutic doses easier to ingest. For dosage advice see my article Harvest The Power of Curcumin To Kill Breast Cancer Cells. I personally use and recommend this brand.
- Essential oils – Vast quantities of research now exist proving beyond a shadow of a doubt exactly how essential oils can be used to enhance immunity. Nearly every single essential oil contains phytochemicals that have research-backed anti-cancer and immune-stimulating properties. This is a huge subject, so if you’d like to know more about how to use essential oils, just subscribe to my information-packed newsletters, all free. Use the sign-up form on the right.
- Glyconutrients – Plant based and organic, glyconutrients supply all eight of the simple sugars our cells require for proper communication, thus assisting with brain function, immune function, etc. When the cells are communicating better, everything starts working at optimal levels. What I like about them is that they help to create healthy stem cells. See my article Breast Cancer Stem Cells – Stopping Them In Their Tracks.
- Goji or Wolfberry (Lycium barbarum) – Goji has good research which indicates its usefulness for increasing immunological responses  and for its usefulness for breast cancer . Best taken in a juice as it tends to preserve the polysaccharide content that dried fruit does not contain. This is a great brand. The other brands I love are Young Living’s NingXia Red (you can get that from me) and Freelife GoChi. Of the 3, the NingXia Red and the GoChi taste the best (they are blended with other things that create a synergy) and seem to work the best.
- Goldenseal (Hydrastis canadensis) – A natural antibiotic, goldenseal contains the phytochemical berberine. It’s wonderful for helping to prevent and fight infections, it is a potent anti-inflammatory, helps boost white blood cells, and one 2010 study found that berberine inhibited the growth of two different types of breast cancer cells better than the chemo drug doxorubicine .
- Green tea (Camellia sinensis) – Contains potent antioxidant compounds that neutralize free radicals and prevent damage to the immune system. In addition, green tea stimulates the liver to secrete interferon, an immune compound that helps fight infection. We also have numerous studies which attest to the cancer-fighting ability of the polyphenols and catechins in green tea. 2016 Chinese research  listed many of the ways tea catechins protect against breast cancer. They (1) protect against DNA damage; (2) regulate cell signalling pathways; (3) interact with estrogen receptors for natural anti-estrogen activity; (4) inhibit DNA methylation; (5) inhibit tumor angiogenesis; (6) inhibit cancer cell proliferation; (7) induce apoptosis of cancer cells; and (8) inhibit metastasis.
- Medicinal mushrooms – Provide amazing support for the immune system, see my article Medicinal Mushrooms – Fungi That Fight Cancer Cells for more information.
- Milk thistle (Silybum marianum) – Protects the liver from a toxic build-up of the drugs, chemicals and anesthetics used in surgery. Milk thistle helps to relieve the constipation associated with surgery. In addition, 2016 Turkish research  found that the phytochemical silibinin found in milk thistle induced apoptosis, inhibited proliferation and had anti-inflammatory effects on estrogen receptor positive, progesterone receptor positive and triple negative breast cancer cells. Please use this herb with caution though – one 2006 research study on animals found that compounds from milk thistle modestly increased mammary tumors in rats. 
- Pau d’arco (Tabebuia impetiginosa)- Herb from South American that stimulates the immune system, helps to detoxify and speed up the healing process post-surgery. It is also a natural antibacterial. Ongoing research on this herb is discovering some of its phytochemicals also have anti-tumor properties, anti-proliferation and anti-angiogenesis properties.
- 4Life Transfer Factors – A supplement specially formulated to help immune cells identify health threats and speed up the immune response to those threats. Transfer factors work by transferring immune memory and knowledge from one entity to another, a rather different approach to immune system support. I’ve taken these myself, have recommended them for hundreds of others and everyone loves how they feel when taking them. This is the particular product I took.
Other Great Supplements/Vitamins
Coenzyme Q10 – A coenzyme helps an enzyme (a protein that speeds up the rate at which natural chemical reactions take place in cells of the body) do its work. Natural sources of CoQ10 include organ meats such as liver, kidney, and heart, as well as beef, sardines, and mackerel. Vegetarians/vegans will get CoQ10 in spinach, broccoli, and cauliflower, as well as legumes such as peanuts and soybeans. Because so many breast cancer patients undergo chemotherapy, and because chemotherapy is so toxic to the heart, CoQ10 is recommended due to its protective effects on the heart. Research indicates low circulating levels of CoQ10 have been associated with increased cancer incidence and poor prognosis.  A 2008 study found that women taking Tamoxifen had higher triglyceride levels which could lead to cardiovascular disease but taking Tamoxifen along with 100 mg of CoQ10 reduced blood lipids and also reduced tumor invasiveness.  The best form to take is ubiquinol (best to avoid ubiquinone). Here is a good brand.
Vitamin D3 – Vitamin D3 influences nearly every cell in your body and most women are deficient, especially if they use sunscreens regularly or live in mostly cloudy conditions. Termed the “sunshine vitamin”, certain amounts of vitamin D come from sunshine in an interesting chemical reaction that happens in the skin. For more information, see my article Why Vitamin D Is So Important For Breast Health. Vitamin D3 also helps to offset some of the side effects of Tamoxifen. To see if you are deficient, get yourself tested at your doctor’s office, ask for the 25-hydroxyvitamin D test. If deficient, supplement. Here’s a good brand.
Selenium – An important nutrient for breast health and many of us are completely deficient. Recent studies confirm that the lower a person’s selenium levels, the greater their risk of cancer. Selenium alters the genes to make the body less susceptible to getting cancer, making this mineral perfect for our wellness regimen. Some forms of selenium also act as natural aromatase inhibitors, which is important for those whose tumors were fed by hormones. For more information on which forms of selenium are the most protective, see the article at  below. To purchase the supplement that contains all three forms as discussed in this article, click here. Note: this is a two-pack, or a 200-day supply. Recommended dosage is only 200 mcg per day. Cheap insurance!
Iodine – Because the thyroid is the main user of iodine and because there is usually a thyroid imbalance with breast cancer, either due to pre-existing conditions or due to breast cancer treatments, it is recommended to have your thyroid checked. If you are found to be in a state of either hyper- or hypothyroidism, iodine supplementation may be necessary. Some of the symptoms of an overactive thyroid include sudden weight loss, rapid heartbeat, increased appetite, nervousness and anxiety, tremors, sweating, changes in bowel patterns, fatigue, difficulty sleeping, skin thinning and fine, brittle hair. The symptoms of an underactive thyroid include weight gain, slow heartbeat, depression, fatigue, intolerance to cold temperatures, dry skin, constipation. If you are experiencing some of these symptoms, best to go and get your thyroid checked out. If you require supplementation, this is an excellent brand of iodine. For more info, you may care to read my article Why Iodine and Selenium Are Useful For Breast Cancer.
Freshly Ground Flaxseed – Flaxseed is broken down by your body into plant chemicals called lignans, which are chemically similar to the hormone estrogen. At first blush, if you have estrogen receptor positive breast cancer this might seem like a bad thing but what occurs is that lignans compete with the body’s own estrogen and, as a result, estrogen exerts less influence. Some researchers believe lignans may be able to slow down the progress of breast cancer and other types of cancer that is hormone driven. Flaxseed is also a great plant source of omega 3 fatty acids, which are natural anti-inflammatories, help to build healthy cells in the body, and often reduce the severity and frequency of hot flashes. Lastly, flaxseed enhances the drug Herceptin for those with HER2 positive breast cancer.  For more information and research links see my article Phytoestrogens – Harmful or Beneficial For Hormone Driven Breast Cancer?
Probiotics – The latest research indicates that taking probiotics is associated with a much reduced risk of breast cancer.  Probiotics are necessary for the proper functioning of a healthy digestive tract and if you have had any form of chemotherapy or radiation, your gut flora will be very much affected and in need of supplementation. Probiotics are also important for boosting your immune system, as much as 85% of your immune system is located in the intestines. For more information see my article How Beneficial Gut Bacteria Reduces Cancer Risk. Considering how inexpensive yet effective it is, this is a very good brand.
DIM – Short for di-indolyl-methane, DIM is a very useful supplement. A 2008 American study reported that DIM inhibits the growth of human cancer cells by interfering with multiple signaling pathways, reducing the invasion, migration, and metastasis (spread) of cancer cells, as well as promoting apoptosis. It is also a potent . Research published in October 2016 by Korean researchers examining the effect of DIM on mice with colitis found that DIM has anti-inflammatory properties (always a good thing for your anti-cancer arsenal). It also suppresses the expression of vascular endothelial growth factor, a growth factor associated with a tumor’s ability to create new blood vessels to feed itself, a process called angiogenesis.  Chinese research published in September 2016 investigating the effects of DIM on mice undergoing total body radiation found that DIM has radioprotective properties . DIM helps to offset the injury that occurs to hematopoiesis, our ability to create new blood cells. This is one of the reasons people can have alarming decreases in various blood cell types when undergoing radiation. Further, joint USA/Chinese research reported in September 2016 (again on mice) found that DIM reduces prostate tumor growth by suppressing a gene known as PCGEM1, while promoting apoptosis.  A joint USA/Indian study on animals released in August 2016 found that two derivatives from DIM (DIM-10 and DIM-14) possessed strong anti-cancer effects, and were responsible for a significant reduction in tumor size in triple negative breast cancer cells.  These are cells that are not affected by hormones or HER2 status. An older 2002 study also found that DIM could induce apoptosis in breast cancer cells independent of estrogen receptor status.  DIM may be beneficial for those carrying the BRCA1/2 gene mutation as well. A small 2014 Canadian research study investigated the ability of DIM to upregulate BRCA1 expression. Upregulating this gene, associated with an increased risk of breast cancer, translates to a reduced cancer risk. Although a small study, the women receiving 300 mg per day (150 mg twice per day) of DIM experienced a 34 percent increase in BRCA1 expression.  There are two brands of DIM I like to recommend: Cape Fear Naturals and Olympian Labs.
