Hi all,

I know this is an old post, but I do take Corvalen M (with magnesium). I take it before breakfast and at night (one scoop each time). I find that it helps with some of my sugar cravings, so it probably does effect blood sugar in some form.

However, I am magnesium deficient in addition to CFS, so I have really found that it helps with energy levels.

Hope this helps!
