Mag-10 Timing

I just started another round of Mag-10. I was looking at the label and I noticed that it recommends 6 caps 1x/day after day one.

Have you guys found it is better to take all 6 at once or to split it up into two doses of 3 taken 8-12 hours apart?

I take all 6 before my workout. On non-workout days I take them in the morniing when I get up.
