The better than expected results of the latest cancer nutritional intervention study were published in the medical Journal European Urology Oncology. This, internationally acclaimed study is now the largest, comprehensive evaluation of the most up-to-date nutritional interventions in this field.
Intake of the new phytochemical rich food blend, YourPhyto, designed for this study, not only significantly slowed PSA progression to a higher degree than previously reported, but for the first time, also improved urinary symptoms and erectile function. In addition, this is the World’s first double blind RCT to show that a probiotic, Yourgutplus, aiming to improve gut health, further reduced PSA progression, improved markers of inflammation and grip strength (markers of overall health & longevity).
This trial provides essential scientific evidence for health professionals and practical guidance for people with cancer, interested in empowering themselves with the most effective strategies to improve their well-being and help alleviate the toxicities of hormonal, radiotherapy or surgical treatments. Men who stopped all other supplements and took 2 capsules of YourgutPlus with 2 capsules of YourPhyto a day had:
- A 44% slower rate prostate cancer progression measured by PSA
- MRI disease correlated with PSA & stabilised or shrunk in 91%
- A 25% improved urinary symptoms
- A 11% improvement in erectile function
- Reduced blood markers of systemic inflammation
- Enhanced grip strength and other markers of longevity

Novel features of the new supplements made for these studies:
YourPhyto contains pomegranate, broccoli, green tea and turmeric, shown to be beneficial in previous studies, by the same research group but now includes new ingredients and embraces advances in food fortification, safety and technology. This includes purification, measurement and standardisation of the candidate phytochemical ensuring each capsule maintains its effectiveness and safety. Traditionally supplements either have extracts of plants or dried whole plants – uniquely, this new supplement has both. This ensures a wide spectrum of synergistically acting natural elements from the whole plant, but also boosts levels of the most active phytochemicals responsible for the health benefits.

Yourgutplus, contains 5 non-histamine inducing, non-diary, lactose secreting lactobacillus bacterial strains, combined with inulin from chicory, and vitamin D. It was previously evaluated and found to be beneficial in the UK national COVID nutritional intervention study and was chosen for the current covid vaccine support study – so has an excellent track record.

Laboratory studies have already shown that manipulating gut bacteria can slow prostate cancer progression but until now, no clinical studies in men, up to now, had evaluated combining phytochemicals with probiotics.
High safety profile: As both these capsules were specifically made for national medical trials the ethical committee insisted on a level of quality assurance unprecedented in supplement manufacturing.
In this double blind randomised clinical trial, men with early but progressive prostate cancer were given the opportunity to try these nutritional interventions before considering treatments such as surgery, radiotherapy or hormone therapies, which have significant risks and toxicities that impact quality of life. 
Never seen before in a nutritional trial, was a finding that MRI scans taken before and after the interventions supported the PSA findings. In the combined group, disease on MRI actually reduced in size in 7% and stabilised in 84%.
Grip strength and Markers of longevity:

In conclusion:
YourPhyto, is now the most up-to-date, comprehensively researched supplement available over the counter. It’s acclaimed scientific evaluation, not only significantly slowed PSA progression to a higher degree than previously reported, but for the first time it, also improved urinary symptoms and erectile function. This is the World’s first double blind RCT to demonstrate that a probiotic intervention, Yourgutplus, aiming to improve gut health, further reduced PSA progression, reduced longevity markers of inflammation and improved grip strength. This combination has been choice for a major intervention study in Women (see below) and further trials are planned evaluating their role for enhancing sports performance, strength and longevity.
