is it the thiamine/riboflavin giving the burst of energy? i've seen a guy or two mention they take a b-complex and after an hour or so they gain a big burst of energy that lasts throughout the afternoon. this sounds great but i'm wondering if there's a drawback longterm or any negatives to worry about. also maybe you don't need the entire b-complex then or perhaps the complex is beneficial rather than specific b vitamins singled out and used in higher doses. seen a lot of other good effects on the body that people have mentioned from taking a high dose b-complex aswell. a good quality b-complex in high dosages but correctly dosaged to each other is ideal it seems like.
