There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Conjugated Linoleic Acid (cla) Overview
Conjugated linoleic acid (CLA) is a type of polyunsaturated fatty acid found in small amounts in the meat and dairy products of certain animals. It is also found in small amounts in some plant-based oils, such as safflower and sunflower oil. The majority of dietary supplements utilize CLA obtained from safflower oil.
CLA has been the subject of numerous scientific studies and has been suggested to have a number of potential health benefits, including weight loss, improving body composition, reducing inflammation, and decreasing the risk of certain types of cancer. However, the evidence for these potential benefits is mixed and more research is needed to fully understand the effects of CLA on health.
Letrozole Overview
-
Letrozole is used treat early breast cancer in women who have experienced menopause (change of life; end of monthly menstrual periods) and who have had other treatments, such as radiation or surgery to remove the tumor. It is also used to treat early breast cancer in women who have experienced menopause and who have already been treated with a medication called tamoxifen (Nolvadex) for 5 years. Letrozole is also used in women who have experienced menopause as a first treatment of breast cancer that has spread within the breast or to other areas of the body or in women whose breast cancer has worsened while they were taking tamoxifen. Letrozole is in a class of medications called nonsteroidal aromatase inhibitors. It works by decreasing the amount of estrogen produced by the body. This can slow or stop the growth of some types of breast cancer cells that need estrogen to grow.
