What is Hydroxytyrosol?
(3, 4-dihydroxyphenylethanol)
Hydroxytyrosol (3, 4-dihydroxyphenylethanol) is a phenolic phytochemical with highly therapeutic antioxidant properties, along with an amphiphilic structure (organic compound) that is concentrated in the cytosol and cell membranes. This indicates Hydroxytyrosol protects the cell cytoplasm in the water-lipid interface of the phospholipid bilayers of the cell cytoplasm, while the endogenous formation of Hydroxytyrosol (DOPET) via dopamine oxidative metabolism. Therefore, hydroxytyrosol is the only concentrated phenol that suprasses the blood brain barrier, mitochondrial biogenesis and function. Essentially this means hydroxytyrosol is a cell permeable nutrient molecule and cell energy compound that is endogenous (internally derived) and utilized on a cellular level.
Polyphenols and simple phenols are secondary metabolites of plants abundant in our diet, including fruits, vegetables, olive oil, wine, tea, legumes, dark coca, herbs and spices. Studies worldwide indicate that the risk of suffering certain diseases is reduced depending on the food categories consumed in our daily diet. Epidemiological data confirms that nutrients in our food groups confer protection against neurodegenerative diseases that are known to present an imbalance between reactive oxygen species (ROS) production and the antioxidant defense system. In nature, hydroxytyrosol (phenolic alcohol) is found much more concentrated in the olive leaves: 1450mg total phenolic/100g fresh leaves vs. 110mg/100g olive fruit and 23mg/100ml extra virgin olive oil. The primary active compounds in olive leaves are Hydroxytyrosol (phenolic alcohol) and Oleuropein (b-glycosidase), which is naturally hydrolyzed in the GI tract, then converts into an aglycone known as Hydroxytyrosol (DOPET).

Hydroxytyrosol Uses for Cancer Patients
Nutritional supplements like Hydroxytyrosol have many health benefits and are being widely used by cancer patients and those at-genetic-risk of cancer. But, is it safe to take Hydroxytyrosol supplements for all types of cancer and without considering any ongoing treatments and other lifestyle conditions? A common belief but only a myth is that anything natural can only benefit me or do no harm. As one example, the use of grapefruit with certain medications is not recommended. Another example, the use of spinach with some blood thinning medications can cause adverse interactions and should be avoided. For cancer, nutrition which includes the food and natural supplements has been shown to influence outcomes. Hence a frequently asked question by cancer patients to dieticians and doctors is “What Should I eat and What Should I Avoid?”.
Taking nutritional Hydroxytyrosol supplements can benefit cancer patients with Stomach Adenocarcinoma on Docetaxel treatment. But avoid Hydroxytyrosol supplements if on Cytarabine treatment for Myeloproliferative Neoplasms. Similarly, taking nutritional supplement Hydroxytyrosol can benefit healthy individuals who are at genetic risk of cancer due to mutation of gene TP53. But avoid taking nutritional supplement Hydroxytyrosol when at genetic risk of cancer due to mutation of gene TERT.
The takeaway being – your individual context will influence your decision if nutritional supplement Hydroxytyrosol is safe or not. And also that this decision needs to be constantly revisited as conditions change. Conditions like cancer type, current ongoing treatments and supplements, age, gender, weight, height, lifestyle and any genetic mutations identified matter. So a legitimate question for you to ask for any recommendation of food and natural supplement is how it is related to your individual context.
