Nutritional supplements like Zeaxanthin 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 Zeaxanthin 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 Zeaxanthin supplements can benefit cancer patients with Endometrial Carcinoma on Cyclophosphamide treatment. But avoid Zeaxanthin supplements if on Etoposide treatment for Retinoblastoma. Similarly, taking nutritional supplement Zeaxanthin can benefit healthy individuals who are at genetic risk of cancer due to mutation of gene TP53. But avoid taking nutritional supplement Zeaxanthin when at genetic risk of cancer due to mutation of gene MRE11.
The takeaway being – your individual context will influence your decision if nutritional supplement Zeaxanthin 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.
Nutritional supplements – vitamins, herbs, minerals, probiotics, and other specialty categories are increasing. Supplements are high concentrations of active ingredients which are also found in different foods. The difference being foods contain more than one active ingredient at lower diffused concentrations. Remember that each of these ingredients has its own science and biological mechanism at molecular level – hence choose the right combination of supplements like Zeaxanthin based on individual context and conditions.
So the question is should you take the supplement Zeaxanthin? Should you take it when at genetic risk of cancer for mutation of gene MRE11? Should you take it when at genetic risk of cancer for mutation of gene TP53? Should you take it when diagnosed with Retinoblastoma? Should you take Zeaxanthin supplements when diagnosed with Endometrial Carcinoma? Should you take it when on Etoposide treatment? Should you continue taking Zeaxanthin supplements if you change your treatment from Etoposide to Cyclophosphamide? So a general explanation like – it is natural or it increases immunity may not be acceptable and sufficient for choosing Zeaxanthin.
Cancer remains an unsolved problem statement. The improved availability of personalized treatments and monitoring of cancer via blood and saliva have been significant factors to improve outcomes. The earlier the intervention – the better the influence on outcome. Genetic testing has the potential to assess cancer risk and susceptibility early. But besides regular monitoring in most cases there are no therapeutic intervention options available. After diagnosis with cancer such as Retinoblastoma or Endometrial Carcinoma, the treatments get personalized to tumor genomics and factors like staging of disease, age and gender. During cancer remission (after treatment cycle is complete) – monitoring is used for assessment of any relapse and accordingly decide next steps. A large majority of cancer patients and those at-risk do take nutritional supplements like Zeaxanthin.
So the question is that are all genetic mutation risks and types of cancers to be considered as one when deciding the use of Zeaxanthin? Are the biochemical pathway implications of genetic risk for cancer due to mutation of gene MRE11 the same as due to mutation of gene TP53? Are the implications of taking Zeaxanthin supplements in Retinoblastoma the same as Endometrial Carcinoma? Is it one and the same if you are on treatment Etoposide or on Cyclophosphamide?
Zeaxanthin – A Nutritional Supplement
Zeaxanthin is a yellow carotenoid with strong antioxidant properties and an essential component for eye health. It is available in the form of dietary supplements. Following are some of the potential health benefits of Zeaxanthin:
- May protect against age-related macular degeneration. (Catharine R Gale et al, Invest Ophthalmol Vis Sci., 2003)
- May protect against Non-Alcoholic Fatty Liver Disease (Krista Christensen et al, Nutrients., 2019)
Zeaxanthin is an active ingredient found in various food items. Papaya contains Zeaxanthin at different concentration levels along with other active ingredients. The molecular pathways which are regulated by Zeaxanthin include PI3K-AKT-MTOR Signaling, DNA Repair, Cell Cycle Checkpoints, JAK-STAT Signaling and Angiogenesis. These cellular pathways directly or indirectly regulate specific cancer molecular endpoints like growth, spread and death. Because of this biological regulation – for cancer nutrition, the right choice of supplements like Zeaxanthin individually or in combination is an important decision to be made. When making decisions on the use of supplement Zeaxanthin for cancer – do consider all these factors and explanations. Because just as true for cancer treatments – Zeaxanthin use cannot be a one-size-fits-all decision for all types of cancers.
Choosing Zeaxanthin Supplements for Your Cancer
The reason there is no easy way to answer the question “When should I avoid Zeaxanthin for Cancer” is because “It Depends!”. Just like the same treatment does not work for every cancer patient, based on your individual context the Zeaxanthin may be harmful or safe. Along with which cancer and associated genetics – the ongoing treatments, supplements, lifestyle habits, BMI and allergies are all factors deciding if Zeaxanthin should be avoided or not and why.
1. Will Zeaxanthin Supplements benefit Cancer Patients with Retinoblastoma undergoing Etoposide treatment?
Retinoblastoma is characterized and driven by specific genetic mutations like RB1 and CRTC1 leading to specific biochemical pathway changes. A cancer treatment like Etoposide works through a specific pathway mechanism of action. The goal is to have a good overlap between the treatment and cancer driving pathways for a personalized approach which is effective. In such a condition any food or nutritional supplement which has a contrary effect to the treatment or reduces the overlap should be avoided. As an example, Zeaxanthin should be avoided for Retinoblastoma along with treatment Etoposide. Zeaxanthin impacts specific pathways which either promote drivers of the disease and/or nullify the treatment effect. Some of the factors which should be considered when choosing nutrition are type of cancer, treatments and supplements being taken currently (if any), age, gender, BMI, lifestyle and any genetic mutation information (if available).
2. Will Zeaxanthin Supplements benefit Cancer Patients with Endometrial Carcinoma undergoing Cyclophosphamide Treatment?
Endometrial Carcinoma is characterized and driven by specific genetic mutations like PTEN and PIK3CA leading to biochemical pathway changes in PI3K-AKT-MTOR Signaling, JAK-STAT Signaling, P53 Signaling, Small Molecule Transport and MAPK Signaling. A cancer treatment like Cyclophosphamide works through specific pathway mechanisms. The goal is to have a good overlap between the treatment and cancer driving pathways for a personalized approach. In such a condition any food or nutritional supplement which has a compatible effect to the treatment or reduces the overlap should be considered. As an example, Zeaxanthin supplements should be considered for Endometrial Carcinoma along with treatment Cyclophosphamide. Zeaxanthin supplements impact pathways/processes like PI3K-AKT-MTOR Signaling and JAK-STAT Signaling which either obstruct drivers of Endometrial Carcinoma and/or improve Cyclophosphamide treatment effect.
Foods to Eat After Cancer Diagnosis!
No two cancers are the same. Go beyond the common nutrition guidelines for everyone and make personalized decisions about food and supplements with confidence.
3. Are Zeaxanthin Supplements Safe for Healthy Individuals with MRE11 Mutation Associated Genetic Risk?
Different companies offer panels of genes to be tested for assessing genetic risk to different cancers. These panels cover genes associated with cancers of the breast, ovary, uterus, prostate, and gastrointestinal system and others. Genetic testing of these genes may confirm a diagnosis and help guide treatment and management decisions. Identification of a disease-causing variant may also guide testing and diagnosis of at-risk relatives. MRE11 is one of the genes generally available in panels for cancer risk testing.
MRE11 mutation causes biochemical pathways/processes like DNA Repair, Stem Cell Signaling, Interferon Signaling, Estrogen Signaling and Angiogenesis to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Zeaxanthin should be avoided when the genetic panel identifies mutation of MRE11 for Breast Cancer. Zeaxanthin impacts pathways/processes like DNA Repair and Stem Cell Signaling and creates adverse effects with MRE11 and related conditions.
4. Are Zeaxanthin Supplements Safe for Healthy Individuals with TP53 Mutation Associated Genetic Risk?
TP53 is one of the genes available in panels for cancer risk testing. TP53 mutation causes biochemical pathways/processes like Cell Cycle Checkpoints, PI3K-AKT-MTOR Signaling, Stem Cell Signaling, TGFB Signaling and Autophagy to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Consider taking Zeaxanthin supplements when the genetic panel identifies mutation in TP53 for Breast Cancer and Lung Cancer. Zeaxanthin supplements impact pathways/processes like Cell Cycle Checkpoints and PI3K-AKT-MTOR Signaling and creates a supportive effect in those with TP53 mutation and related conditions.
* Other Factors are also included like BMI, Treatments, Lifestyle Habits
The two most important things to remember are that cancer treatments and nutrition are never the same for everyone. Nutrition which includes food and nutritional supplements like Zeaxanthin, is an effective tool which can be controlled by you, while facing cancer.
What food you eat and which supplements you take is a decision you make. Your decision should include consideration of the cancer gene mutations, which cancer, ongoing treatments and supplements, any allergies, lifestyle information, weight, height and habits.
