I need all the anti-aging news I can get (Part 2)

I still wish to stay young forever.

I wonder what happens if I eat a high-dose supplements every day the rest of my life. Will I soften the threat of premature aging, death and chronic diseases by doing that?

I’ve seen some confusing news in the paper about vitamin E and I now wonder about its safety.

I am an ordinary person; I want to find out what is true and what isn’t?

Here they claim that Science Says You Need High-Dose Supplements, is that correct? They use eight scientific studies, to show why you need supplements - but no useful references.

Top scientists call vitamin E safe and beneficial, this web page have testimonials and you can reorder their products. I see all the signs of quackery and nothing to prove that vitamin E is safe and beneficial.

Council for Responsible Nutrition (CRN) claim that vitamin E supplementation is safe and do no harm at all, because it's like all vitamins, essential for life. The benefits of vitamin E is protection against free radicals, heart disease, cancer, macular degeneration and it improves brain function enchancing short term memory while reducing the risk of developing Alzheimer’s disease.

Can I believe that? Possibly this web site is supported by the dietary supplements industry, and they do not present any information which would suggest that any supplements are unsafe or harmful.

I also found a study published in a refereed medical journal published by the National Cancer Institute. The study was double-blinded and placebo-controlled with 540 participants. I consider that must be pretty reliable information:

Vitamin E has adverse effects on recurrence of cancer and survival in cancer patients.

Read about it here:
A randomized trial of antioxidant vitamins to prevent second primary cancers in head and neck cancer patients.

CONCLUSIONS: alpha-Tocopherol supplementation produced unexpected adverse effects on the occurrence of second primary cancers and on cancer-free survival.

Meta-analysis: high-dosage vitamin E supplementation may increase all-cause mortality.

CONCLUSION: High-dosage (> or =400 IU/d) vitamin E supplements may increase all-cause mortality and should be avoided.

Many benefits of vitamin E found in previous studies are due to natural /gamma/ -tocopherol found in foods. Besides that, the health benefits of nut consumption are attributed partly to the tocotrienols they contain.

In this prospective study, higher concentrations of plasma gamma-tocopherol were associated with a statistically significant lower risk of developing prostate cancer.

CONCLUSIONS: The use of combined - and - tocopherol supplements should be considered in upcoming prostate cancer prevention trials, given the observed interaction between -tocopherol, -tocopherol, and selenium.

MY CONCLUSION, so far- is that eating high-dose supplements of E vitamin every day isn't always safe. In some cases E supplements may increase all-cause mortality and should directly be avoided and in other cases there are unexpected effects. Truly, E vitamin can be unsafe or harmful. Vitamins E from real food causes absolutely none of the artificially produced negative effects as seen in the mentioned studies.
