Sharmin,
You can take the B complex either way. It's more a matter of personal preference than anything. If you are feeling tired, you may want to try twice daily to see if it makes any difference by having a constant dose in your body.
Manal,
The amount of B vitamins in Yummi Bears is fairly low so it is OK to use a B complex also.
Umair,
Don't forget that there are also amounts of these minerals taken from diet. The ratio is only approximate so a bit more zinc is not a problem. The main thing is to make sure some copper is taken if on long term zinc supplements.
