I take them both at breakfast too - but someone once told me you're meant to take one with breakfast and one with dinner - the idea being that your body can't store some of the goodies in the pills so if you take them all at once and your body doesn't need that high a dose, the rest just goes to waste. But that was just their opinion!
I'm sure if it was important it would say 'take 1 tablet twice a day with meals' instead of just 'take 2 tablets a day.'
I have always taken mine together since it is easier to remember that way and I always feel sick at night anyway so mornings are best for me.
