Hi all, does anyone know if its ok to take colagen supplements with letrazole
Hi polly5
Thank you for your post.
Many people ask about vitamins, supplements and herbal medicines, as they want to do as much as possible to be healthy following a diagnosis of breast cancer or to help manage the side effects from treatments such as letrozole. There is often the belief that these products are safe as they are considered natural.
However, most 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’s not possible for us to say if it is safe for you to take collagen supplements. There is research looking at collagen levels and breast cancer, but it is not clear if this would mean that collagen supplements should be avoided. There is currently not enough evidence to recommend taking collagen supplements after a cancer diagnosis or during treatment.
It’s important to speak to your breast care nurse, treatment team, GP, or a pharmacist before taking any supplements such as collagen when taking letrozole or other prescribed medicines.
You can search this American website, Memorial Sloan Kettering Cancer Centre, for information about individual supplements. 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
