I found Chinese Chlorella (which seems to be Chlorella with ALA and other things included) a great help. I still experience highs and lows, but at least there are highs now, wheras before they're weren't any. Do make sure the Chlorella is good quality Chlorella -- perhaps you could test out different brands -- as I've heard Chlorella attracts mercury in its natural environment.

I've been taking Chlorella for around 3 months now, and I have seen improvements, particularly with my gut, but I'd still classify myself as ill.

I will also try taking garlic.
