FS-greens Mango and Tamoxifen

After starting Tamoxifen last July following Breast Cancer surgery I have been suffering from menopause symptom’s which I was told would happen so no big suprise. A friend of mine has started going through the menopause and recommended a product she had started taking called FS-Greens Mango that she feels has really helped her with some of her symptoms. I am thinking of giving this product a try but just wanted to check that there is nothing in the ingredients that I should be avoiding while taking Tamoxifen. I have had a look online but found conflicting information. I have included a photo of the product/ingredients which seem innocent enough but just wanted to double check.

Hi nichola78. It is so hard not knowing what is safe or not isn’t it. I have (and continue!) to tie myself up in knots over this. I was pointed the direction of the Memorial Sloan Kettering website as a reputable source so not sure if you have checked there? I would say that I have stopped taking a product with ashwaghanda in though as heard that ‘may’ be problematic. Pineapple I think is similar. However the quantities here may be small. As ever, I would check with your breast care team.

Hi nichola78

Thanks for posting.

Many people ask about products such as these as well as vitamins and herbs as they want to do as much as possible to be healthy and to help manage side effects of treatment for breast cancer.

There is often the belief that these types of products are safe as they are considered natural. However, there is much we don’t know about things like superfoods, supplements and herbal remedies as they don’t have to comply with the same regulations or rigorous testing that conventional medicines do. For many products there is a lack of research to support their use, and some can interfere with conventional medicines including cancer treatments.

It can be difficult to check the safety of products particularly when they contain so many ingredients. As @blue80 says, you can search this American website, Memorial Sloan Kettering Cancer Centre, for information about individual herbs and vitamins included. Each has sections on existing evidence and what known interaction there is with other medications. You may find that that some herbs have different names in America. You can also search herbal products and supplements on the European website Complementary and Alternative Medicine for cancer and on the American website Medicine Plus

However, as @blue80 also mentions, it’s important to check with your treatment team, oncology pharmacist or GP before taking any vitamins, supplements or herbal and superfood products.
