This study doesn’t establish maximum safe dosages or what dosages are associated with liver damage, but only says that sometimes these nutrients are associated with liver damage. Mostly, presented this way, it is just a big pharma support piece. One of the compounds targeted is Tumeric, and it is almost impossible to find a reference for what the toxicity of Tumeric is, generally, the recommendations run 500mg to 2000mg of 95% Curcumin extract, which is one whopping amount of Tumeric as a spice. Nevertheless, most Curcumin or Tumeric just slides right through you unabsorbed. This is why they add Paprin (black pepper) to the mix, to get it past the gut. And then it flushes out of your system quickly.. so hard to know what to make of this study. Some of the items on this list are just plain bad, incontrovertibly. Garcinia cambogia for one.. just avoid it. But, this is kind of just bad talking and grouping things without any real information to give the people who are interested real tools to find their own safe dosages.
What I noticed is there is no attempt to determine if the damage is DUE to taking supplements, or because people experiencing problems are more likely to TAKE supplements.
Seems that makes the entire article worthless.
It may be the equivalent of saying wet roads cause rain...
