It is really hard to say. It may be easier to "map out" your ALK
usage over the course of a couple weeks to see what those levels do. Then you could adjust your dosing to match the depleting levels.
Or for the impatient...
Just begin using the recommended dosage and test your levels each day. If you see them starting to rise, cut back. If they are falling, dose more. It is really trial and error more than anything else.
I don't have any experience with B-Ionic. I use Kent's Tech CB series. I believe those two products are pretty much neck and neck with each other as far as popularity and usage.
