Vitamin C
A daily dose of – wait for it – 7-10 g vitamin C [structural formula shown below] may protect steroids users against prostate cancer. Lower doses may protect the prostate of non-users, conclude researchers at Seoul National University College of Medicine after doing tests on rats. Their article will be published soon in the Journal of Nutritional Biochemistry.
The reason that the Koreans examined whether vitamin C cancels out the undesirable effect of testosterone on the prostate is a theoretical one. According to recent research, the prostate grows because cells that are influenced by androgens produce more of the transcription factor HIF-1alpha. This leads to an increase in the production of VEGF, a hormone that stimulates the creation of new blood vessels. If the prostate grows and prostate cells start to divide, the risk of errors occurring in the genetic material of the cells increases. And if that happens, cancer cells may start to form.
HIF-1alpha is deactivated by HIF-1-prolylhydroxylases. And the more vitamin C there is in the cells, the harder these enzymes work.
But the proof of the pudding is in the eating. So the researchers injected rats with testosterone [T]. The dose was 10 mg/kg/day. Some of the rats were also given a megadose of vitamin C [T+VC]. A control group was given nothing at all [C]. The figure below shows that testosterone increases the production of the prostate cancer protein PSA, and that vitamin C reduces this. The more PSA men have in their blood, the greater the chance of them developing prostate cancer.
After four weeks of supplementation, the researchers observed that the vitamin had reduced the growth of the prostate. The effect was noticeable but somewhat disappointing. The left-hand prostate in the photo below is from a C rat, the one in the centre is from a T rat, and the right-hand prostate comes from a T+VC rat. The researchers suspect that a longer course of vitamin C than the four weeks of the experiment would have had a greater inhibitory effect
The rats in the T group, exactly as the theory predicted, started to produce more HIF-1alpha. The addition of vitamin C reduced this effect
Vitamin C works primarily through the enzyme PHD2, the Koreans discovered during the experiment.
They believe that their discovery explains why, in epidemiological studies, men who consume large quantities of fruit and vegetables in their diet develop prostate cancer less often. They also think that their study will be of interest to doctors who treat prostate cancer, as it shows that high doses of vitamin C administered through a drip can help fight prostate cancer. We at Ergo-log thought of those of our readers who, for whatever reason, have higher levels of androgens in their bodies.
A normal person who takes oral supplements can manage about one gram a day of the cheap vitamin C analogues. With milder versions it’s possible to achieve much higher amounts.
