there is no evidence that taking extra b vitamins helps or hinders weight loss. while these vitamins play an important role in metabolism taking extra does not rev of the metabolism. i suggest you see a registered dietitian to see what supplements you need by examining your diet. supplements should be taken when there is a shortfall in the diet. as for weight loss looking more at what and how much you are eating along with physical activity is key. for more information on troubleshooting your weight see this article. good luck!
can too much vitamin b and folic acid be detrimental to weight loss? . i am 52 and trying to lose weight. i take a multivitamin but to try and help my metabolism i'm taking folic acid daily plus i alternately take vitamin b6 and b12. i exercise and eat right but am not losing. a few years ago i was only taking a multivitamin along with green tea tablets and lost a lot of weight. my husband suggested that now i may be taking too much of the other supplements. could he be right? could i be getting all i need of these in my multivitamin?
