New Research on Manuka Honey and Breast Cancer
A research team at UCLA recently published a study in the peer-reviewed journal Nutrients exploring a potential link between Manuka honey and breast cancer. The findings suggest that this honey, which is particularly high in methylglyoxal (MGO), may affect the growth of certain breast cancer cells in laboratory and animal models.
Research into the relationship between Manuka honey and breast cancer is still in its early stages, but a recent study from UCLA has produced some genuinely interesting findings. Here is what the science shows, and where it currently stands.

Understanding the Study: Manuka Honey's Role in Breast Cancer
The research on Manuka honey and breast cancer focused on understanding how MGO-rich honey interacts with human breast cancer cells. Scientists conducted both in vitro (cell culture) and in vivo (living organism) testing to assess whether Manuka honey could slow the growth of cancerous cells. Their results showed that Manuka honey reduced the growth of certain breast cancer cells, particularly oestrogen receptor-positive cells, while appearing to leave healthy cells largely unaffected.
One of the notable findings related to Manuka honey and breast cancer was its interaction with tamoxifen, a drug commonly used to treat oestrogen receptor-positive breast cancer. When tested in combination, Manuka honey appeared to enhance tamoxifen's ability to suppress cancer cell growth more effectively than the drug alone.
The Science Behind Manuka Honey and Breast Cancer Cells
The researchers found that Manuka honey and breast cancer cells interact through a process known as apoptosis, which is essentially programmed cell death. In the context of cancer, this means the honey appeared to trigger a shutdown mechanism in certain cancer cells, reducing their ability to replicate and spread.
What makes the findings on Manuka honey and breast cancer particularly worth noting is the selectivity observed in the lab. Unlike many cancer treatments, which affect both healthy and cancerous cells, the honey appeared to act more selectively on cancer cells in this study. These results come from controlled laboratory conditions, and human clinical trials have not yet been conducted.
Combining Manuka Honey with Traditional Treatments
Another important aspect of the study on Manuka honey and breast cancer was the honey's interaction with tamoxifen. Over time, some patients develop resistance to tamoxifen, which limits its effectiveness. In laboratory conditions, when Manuka honey was combined with tamoxifen, the combination had a greater effect on slowing cancer cell growth than either substance alone.
This finding raises the possibility that Manuka honey could eventually be studied as a complement to existing treatments. That said, this remains a hypothesis for future research to explore, not a clinical recommendation. Anyone currently undergoing cancer treatment should discuss any dietary supplements with their oncologist before making changes.
Broader Implications: Manuka Honey’s Impact Beyond Breast Cancer
While this study focused primarily on Manuka honey and breast cancer, the research team also looked at the honey's effects on lung and pancreatic cancer cells. These cancers are generally aggressive and difficult to treat. The results showed similar anti-proliferative properties in those cell types as well, though the same caution about early-stage findings applies.
The researchers believe one mechanism involves the PI3K/AKT/mTOR pathway, a signalling route that many cancer cells rely on to grow and survive. By disrupting this pathway, Manuka honey may interfere with a key cancer cell survival mechanism. This adds a degree of scientific plausibility to the findings, though human trials would be needed to understand whether this effect is meaningful in practice.
Testing in Animal Models: What the Results Showed
The findings from laboratory cell cultures were followed up with animal model testing. Researchers administered Manuka honey orally to mice with breast cancer tumours and observed that tumour growth was reduced in the treated group compared to untreated mice.
These results with Manuka honey and breast cancer in animal models are a meaningful step beyond in vitro testing. They suggest the observed effects are not limited to a petri dish environment. However, results in mice do not automatically translate to outcomes in humans. Animal model studies are an important research stage, but they represent an early step in a long process before any clinical application could be considered.
What's Next for Manuka Honey and Breast Cancer Research?
The study provides an early scientific basis for further investigation into the relationship between Manuka honey and breast cancer. Human clinical trials would be required to establish whether the effects observed in lab and animal settings occur in people, at what doses, and with what safety profile.
At Manuka Hut, we think it is worth sharing research like this accurately and carefully. The connection between Manuka honey and breast cancer is a legitimate area of early scientific inquiry. We believe our customers deserve access to credible, balanced information about the natural foods they consume, and we will always present the science as it actually stands.
Choosing Quality Manuka Honey
If you are interested in incorporating Manuka honey into your diet, quality and certification matter. UMF (Unique Manuka Factor) and MGO ratings are the primary ways to verify that a Manuka honey product contains the active compounds found in research studies. Not all products labelled "Manuka honey" carry the same potency.
Manuka Hut stocks independently certified, UMF-graded Manuka honey sourced directly from New Zealand. If you have questions about UMF ratings, MGO levels, or how to select the right strength, our product pages and educational content are a good place to start.

The research discussed involves laboratory and animal model findings and has not been replicated in human clinical trials. Always consult a qualified healthcare professional before making any changes to your treatment plan or adding supplements (including Manuka honey) to your routine, particularly if you are managing a cancer diagnosis.
Frequently Asked Questions
How does Manuka honey work against breast cancer cells?
In laboratory studies, Manuka honey appeared to promote apoptosis (programmed cell death) in breast cancer cells, particularly oestrogen receptor-positive types. It also appeared to disrupt the PI3K/AKT/mTOR signalling pathway, which cancer cells rely on for growth and survival. These findings come from in vitro and animal research, not human trials.
What did the UCLA study find about Manuka honey and breast cancer?
The study, published in Nutrients, found that Manuka honey slowed the growth of oestrogen receptor-positive breast cancer cells in laboratory conditions and in mice. It also found that combining Manuka honey with tamoxifen produced a greater suppressive effect on cell growth than tamoxifen alone. Human clinical trials have not yet been conducted.
Can Manuka honey be used alongside traditional breast cancer treatments?
The study raises the question of whether Manuka honey might complement treatments such as tamoxifen, but this is not yet established. More research is needed before any recommendation could be made. Anyone undergoing cancer treatment should speak with their specialist before changing their diet or adding supplements.
Is Manuka honey effective against all types of breast cancer?
The most notable effects in the study were observed with oestrogen receptor-positive breast cancer cells. Effects on triple-negative breast cancer cells were less significant. The study does not support a conclusion that Manuka honey is broadly effective across all breast cancer types.
