This infomercial from Albion Minerals is absolutely accurate except for one thing. Albion glycinated minerals are not effective in terms of improving health. The infomercial emphasizes that Albion glycinated minerals are not available in the gut which is totally accurate but rather bypass the gut, however, that is a huge drawback. Minerals from mineral supplements to be effective in terms of improving health must be both available in the gut and be available systematically.
Usually mineral supplements are supplemented when blood mineral levels are normal and more of a mineral can be helpful when blood levels are normal but more of the mineral must be available in the gut.
At this time the view expressed in this post is my personal opinion and not backed by peer-reviewed published scientific research.
