On the one hand, caffeine effects appear to be detrimental to short-term memory, working memory included, whereas the effects are somewhat positive for memory over the long term (for example, remembering something better many days later if caffeine was ingested during encoding as well as retrieval, as opposed to no caffeine [7]). Many of the ...

[ 114 ] [ 115 ] Studies have found a connection between elevated plasma tHcy and an increased risk of bone fractures, but is unknown whether this is related to the increased levels of tHcy or to vitamin B 12 levels (which are involved in ...
