COGNUTRIN in Breast Cancer Survivors

The purpose of this study is to examine the safety and influence of an intervention (COGNUTRIN) using nutritional supplements (n-3 fatty acids and blueberry anthocyanins) on cognitive performance in breast cancer survivors following chemotherapy. The investigators' goal is to treat or lessen the late effects of cancer treatment. The supplement to be used will be a combination of the following: (1) VitaBlue (40% polyphenolics, 12.5% anthocyanins from blueberries (BB) and (2) n-3 fatty acids - Lovaza.

This pilot study will evaluate the feasibility of administration of the nutritional supplement and placebo in this patient population and performing cognitive function testing at baseline and post supplementation.

This is a randomized, double-blind pilot study of COGNUTRIN vs. Placebo.

Participants have an equal chance (like flipping a coin) of being in either of the study groups. Neither the participant nor the study doctor will be able to choose which study group the participant is in. Participants will not know and the study doctor will not know which study group the participants are in.

Eligibility Criteria:
Inclusion Criteria:

* Eastern Cooperative Oncology Group (ECOG) performance status of 0- 2 (Karnofsky score \>60%)
* Acceptable hemoglobin and hematocrit level based on complete blood count (CBC)
* Must be willing to be monitored for adequacy of nutritional intake during the intervention, as is the current standard of clinical practice

Exclusion Criteria:

* Use of estrogens (oral, dermal or vaginal), progesterone (oral or topical), androgens, Raloxifene or Tamoxifen during the previous 3 months
* Use of over the counter steroid hormonal supplements including dehydroepiandrosterone (DHEA)
* Patients with advanced or Stage IIIIB or IV breast cancer or other cancers
* Use of n-3 fatty acids or high dose antioxidant supplements other than what is provided in the trial

* Evidence of bleeding diathesis or coagulopathy
* Metabolic abnormalities (e.g. thyroid disorders, insulin dependent diabetes, rheumatologic disease etc.)
* Known claustrophobia, presence of pacemaker and/or ferromagnetic material in their body that would prohibit MRI imaging
