I can't believe how many of you take vitamins!
Although I used to take vitamin C but stopped now i'm doing nutrition in uni.
Like other people have said you don't need suplements if you eat the right foods that already provide these vitamins.
Get your 5-a-day!
I read somewhere that it has been shown that taking Vit-b12 supplements can actually increase your deficiency. Which is not good! so its best to try and eat food which contain it;
For Vit-B12: eat meat, dairy products and eggs
If you DON'T eat dairy products/ meat: you can buy fortified foods with B12 in it.
Such as: veggieburgers, soya milks, vegetables, sunflower margarines and breakfast cereals.
