Nos a cikk szerint "Now these guidelines aren't designed for athletes. Those folks that are active obviously need more C than the non-active person would.". Lefordítva magyarra: semmi se támasztja alá, de mi így gondoljuk

Nézzük mit mond a tudomány:

"Participants were randomly allocated to one of two groups. The first group was required to take 1,000 mg of vitamin C and 235 mg of vitamin E each day, which the researchers say is consistent with the amount found in store-bought supplements. The second group received a placebo pill each day."

"The researchers note that the supplements had no impact on the participants' maximal oxygen uptake or their results in a 20-meter shuttle test."

"The variables used have included maximum oxygen uptake, blood lactic acid levels, and heart rate after exercise, and in some cases performance was assessed in competitive events. The results have been equivocal: Most studies could not demonstrate an effect."

"Although there is some evidence to show that both antioxidants can reduce indices of oxidative stress, there is little evidence to support a role for vitamin C and/or vitamin E in protecting against muscle damage. Indeed, antioxidant supplementation may actually interfere with the cellular signalling functions of ROS, thereby adversely affecting muscle performance."

"Since the potential for long-term harm does exist, the casual use of high doses of antioxidants by athletes and others should perhaps be curtailed."

"Thirty-two recreationally strength-trained men and women were randomly allocated to receive a vitamin C and E supplement (1000 mg day−1 and 235 mg day−1, respectively), or a placebo, for 10 weeks."

"The supplementation did not affect the increase in muscle mass or the acute change in protein synthesis, but it hampered certain strength increases (biceps curl)."

"vitamin C and E supplements in high dosages should be avoided by healthy, young individuals engaged in strength training."

De ez csak egy gyors keresés volt, valószínűleg lehetne még találni. Nem lesz valami attól igaz, hogy az interneten leírják (ugye a klasszikus idézet ). Utána kell nézni, hogy vannak-e mögötte tények, meg elég sok mindenről kiderül, hogy nincs. Még akkor is, ha amúgy az adott területen "magától értetődő", hogy így van.
