This study tested the effect of vitamin C supplementation on tumor growth and metastasis.
Humans cannot produce vitamin C.
However, most animals can.
To investigate the effect of vitamin C supplementation on metastasis and tumor growth in mice, the researchers altered the mice in a way that they were not able to synthesize vitamin C anymore.
The mice were induced with melanoma or breast cancer cells. 4 weeks prior to and 2 weeks after cancer induction the mice were fed with either a standard diet or a standard diet enriched with vitamin C.
The results showed that vitamin C supplementation hindered metastasis, tumor growth and inflammation.
Further details can be found in the study.
