Nutritional supplements like Garcinia Cambogia 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 Garcinia Cambogia 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 Garcinia Cambogia supplements can benefit cancer patients with Stomach Adenocarcinoma on Docetaxel treatment. But avoid Garcinia Cambogia supplements if on Cytarabine treatment for Myeloproliferative Neoplasms. Similarly, taking nutritional supplement Garcinia Cambogia can benefit healthy individuals who are at genetic risk of cancer due to mutation of gene CDKN1B. 

The takeaway being – your individual context will influence your decision if nutritional supplement Garcinia Cambogia 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. 

Brief Overview

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 Garcinia Cambogia based on individual context and conditions. 

Which Cancer Types to Avoid Garcinia Cambogia Supplement

So the question is should you take supplement Garcinia Cambogia? Should you take it when at genetic risk of cancer for mutation of gene CDKN1B? Should you take it when diagnosed with Myeloproliferative Neoplasms? Should you take Garcinia Cambogia supplements when diagnosed with Stomach Adenocarcinoma? Should you take it when on Cytarabine treatment? Should you continue taking Garcinia Cambogia supplements if you change your treatment from Cytarabine to Docetaxel? So a general explanation like – it is natural or it increases immunity may not be acceptable and sufficient for choosing Garcinia Cambogia. 


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 Myeloproliferative Neoplasms or Stomach Adenocarcinoma, 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 Garcinia Cambogia.

So the question is that are all genetic mutation risks and types of cancers to be considered as one when deciding the use of Garcinia Cambogia? Are the implications of taking Garcinia Cambogia supplements in Myeloproliferative Neoplasms the same as Stomach Adenocarcinoma? Is it one and the same if you are on treatment Cytarabine or on Docetaxel? 

Garcinia Cambogia – A Nutritional Supplement

Garcinia Cambogia is a tropical fruit, native to India and Southeast Asia. It is also available in the form of dietary supplements and is commonly used as a weight loss supplement. Garcinia Cambogia contains hydroxycitric acid (HCA). Following are some of the potential health benefits of Garcinia Cambogia:

Excess intake of Garcinia Cambogia supplements may lead to certain side effects like  gastrointestinal problems, nausea, headache, and upper respiratory tract symptoms. Garcinia Cambogia supplements contain many active ingredients including Guttiferone A and Garcinol at different concentration levels. The molecular pathways which are regulated by Garcinia Cambogia include Extracellular Matrix Remodelling, Stem Cell Signaling, TGFB Signaling and Cell Cycle Checkpoints. 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 Garcinia Cambogia individually or in combination is an important decision to be made. When making decisions on the use of supplement Garcinia Cambogia for cancer – do consider all these factors and explanations. Because just as true for cancer treatments – Garcinia Cambogia use cannot be a one-size-fits-all decision for all types of cancers.

Choosing Garcinia Cambogia Supplements for Your Cancer

The reason there is no easy way to answer the question “When should I avoid Garcinia Cambogia for Cancer” is because “It Depends!”. Just like the same treatment does not work for every cancer patient, based on your individual context the Garcinia Cambogia 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 Garcinia Cambogia should be avoided or not and why.

1. Will Garcinia Cambogia Supplements benefit Myeloproliferative Neoplasms Patients undergoing Cytarabine treatment?

Myeloproliferative Neoplasms is characterized and driven by specific genetic mutations like JAK2 and CALR leading to specific biochemical pathway changes. A cancer treatment like Cytarabine 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, Garcinia Cambogia should be avoided for Myeloproliferative Neoplasms along with treatment Cytarabine. Garcinia Cambogia 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 Garcinia Cambogia Supplements benefit Stomach Adenocarcinoma Patients undergoing Docetaxel Treatment?

Stomach Adenocarcinoma is characterized and driven by specific genetic mutations like TP53 and MUC16 leading to biochemical pathway changes in Extracellular Matrix Remodelling, TGFB Signaling, JAK-STAT Signaling, Small Molecule Transport and PI3K-AKT-MTOR Signaling. A cancer treatment like Docetaxel 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, Garcinia Cambogia supplements should be considered for Stomach Adenocarcinoma along with treatment Docetaxel. Garcinia Cambogia supplements impact pathways/processes like Extracellular Matrix Remodelling and TGFB Signaling which either obstruct drivers of Stomach Adenocarcinoma and/or improve Docetaxel treatment effect.

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 Garcinia Cambogia Supplements Safe for Healthy Individuals with CDKN1B 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. TERT is one of the genes generally available in panels for cancer risk testing. 

CDKN1B is one of the genes available in panels for cancer risk testing. CDKN1B mutation causes biochemical pathways/processes like Stem Cell Signaling, Cell Cycle Checkpoints, FOXO Signaling, PI3K-AKT-MTOR Signaling and Angiogenesis to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Consider taking Garcinia Cambogia supplements when the genetic panel identifies mutation in CDKN1B for Neuroendocrine Cancer. Garcinia Cambogia impacts pathways/processes like Stem Cell Signaling and Cell Cycle Checkpoints and creates a supportive effect in those with CDKN1B mutation and related conditions.

In Conclusion

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 Garcinia Cambogia, 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.

The nutrition planning for cancer from addon is not based on internet searches. It automates the decision making for you based on molecular science implemented by our scientists and software engineers. Irrespective of whether you care to understand the underlying biochemical molecular pathways or not - for nutrition planning for cancer that understanding is needed.

Get started NOW with your nutrition planning by answering questions on the name of cancer, genetic mutations, ongoing treatments and supplements, any allergies, habits, lifestyle, age group and gender.
