Abstract: 
We found that a specific combination of ascorbic acid (AA, 100µM), proline (P, 140 µM) and lysine (L, 400 µM) had a significant antiproliferative and antimetastatic effect against some human cancer cell lines, breast (MDA-MB-231), colon (HCT116) and skin (melanoma, A2058). In the presence of this nutrient combination the invasion of the extracellular matrix by human breast cancer cells, melanoma cells and colon cancer cells was inhibited by 50%, 10% and 30% respectively. Addition of epigallocatechin gallate (EGCG) further enhanced this nutritional synergy producing a more pronounced inhibitory effect on both cellular proliferation and matrix invasion.
