Nov. 10, 2008 — An eight-year study involving about 15,000 male physicians fizzled to appear a benefit for vitamins C and E in preventing heart attacks or strokes.

The unused consider bolsters previous findings from other huge trials appearing no benefit for vitamin E. But it is one of the primary expansive thinks about to examine the affect of vitamin C supplementation on cardiovascular risk.

“We saw no impact for either vitamin E or C in this consider of men with a moo initial chance for cardiovascular infection,” researcher Howard D. Sesso, ScD, of Boston’s Brigham and Women’s Healing center, tells WebMD.
