Speculation why Selenium didn't help
[edit]https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3022975/ Published online 2010: SELECT was a phase III randomized, placebo-controlled trial of selenium (200 μg/d from L-selenomethionine), vitamin E (400 IU/d of α-tocopheryl acetate) or both. Possible reasons Selenium didn't work:
- The use of L-selenomethionine rather than high-selenium brewer’s yeast was influenced by logistic factors. L-selenomethionine is only one of >20 selenium-containing species in brewer’s yeast.
- The NPC study participants who clearly benefited from selenium administration had lower baseline selenium levels, but the relevance of this finding to SELECT is unclear.
- Too large daily dose of Selenium. Much over daily requirement.
