Quick question about the B-vitamins

[jayman2606]

I am seeking some advice about B vitamins. I struggle to get these because I am a vegetarianist. I used to take supplements but then realised the RDA's for some unknown reason are totally out on these. I checked them out earlier today again at Holland and Barrett and the standard B vitamin supplement has 2500% B12. Along with another two B vitamins that are like 500% of the RDA. I mean surely these are way out-can someone explain this? Also does anyone have any quick suggestions for B vitamin sources...I know about leafy green veg and fantastic marmite but there must be more!

Thanks in advance
