癌治療の高用量ビタミンC点滴治療は
ビタミンCの酸化作用←
（抗酸化とか活性酸素除去能、ではない）
を利用し癌細胞壊死目的で投与、なので
ビタミンC過量摂取は遷移金属と出会い酸化作用もつし（サプリで過量摂取をするな、と）
ビタミンCは生理的条件下で酸化促進するか？

抗酸化サプリメントの過量摂取は癌の腫瘍径を増加させたり（マウス実験）、
癌の遠隔転移速度を速める報告もあり
（NHK Eテレ加齢黄斑変性症の番組内で眼科の先生が、適量を飲んでくれ、飲み過ぎは逆に癌の径を大きくする報告も、と言って、適量を飲めとテロップも出たよ。加齢黄斑変性症の話しで、だけど。）
癌は個別医療の時代なので
サプリメントで効果がある人に水をさすつもりはないです。
効果がないのに「体にいいものだから」と漫然と飲むものではないんじゃないか、と。
保険薬もサプリも工場で製造してる工業製品だし
自分もクエン酸粉末を水に溶いて美味しく飲んだので全否定じゃないです。
「サラサラにするためにアルミニウムも入ってるんだろうなー」と思いながら飲んだけど（病院の保険薬も同じです）
Vitamin C and selenium had no significant effect on mortality.
Treatment with beta carotene, vitamin A, and vitamin E may increase mortality.

Antioxidant supplements are used for prevention of several diseases.
OBJECTIVE:
To assess the effect of antioxidant supplements on mortality in randomized primary and secondary prevention trials.
DATA SOURCES AND TRIAL SELECTION:
We searched electronic databases and bibliographies published by October 2005.
All randomized trials involving adults comparing beta carotene, vitamin A, vitamin C (ascorbic acid), vitamin E, and selenium either singly or combined vs placebo or vs no intervention were included in our analysis.
Randomization, blinding, and follow-up were considered markers of bias in the included trials.
The effect of antioxidant supplements on all-cause mortality was analyzed with random-effects meta-analyses and reported as relative risk (RR) with 95％ confidence intervals (CIs).
Meta-regression was used to assess the effect of covariates across the trials.
DATA EXTRACTION:
We included 68 randomized trials with 232 606 participants (385 publications).
DATA SYNTHESIS:
When all low- and high-bias risk trials of antioxidant supplements were pooled together there was no significant effect on mortality (RR, 1.02; 95％ CI,0.98-1.06).
Multivariate meta-regression analyses showed that low-bias risk trials (RR,1.16; 95％ CI, 1.04[corrected]-1.29) and selenium (RR, 0.998; 95％ CI, 0.997-0.9995) were significantly associated with mortality.
In 47 low-bias trials with 180 938 participants, the antioxidant supplements significantly increased mortality (RR, 1.05; 95％ CI, 1.02-1.08).
In low-bias risk trials, after exclusion of selenium trials, beta carotene (RR, 1.07; 95％ CI, 1.02-1.11), vitamin A (RR, 1.16; 95％ CI, 1.10-1.24), and vitamin E (RR, 1.04; 95％ CI, 1.01-1.07), singly or combined, significantly increased mortality.
Vitamin C and selenium had no significant effect on mortality.
CONCLUSIONS:
Treatment with beta carotene, vitamin A, and vitamin E may increase mortality.
The potential roles of vitamin C and selenium on mortality need further study.
