Oooh vitamins. Don't do that - my other half had a blood test and was told he was seriously deficient in folate and vitamin D and went on a course of nice strong women's vitamins (men's ones don't have folate). A few weeks later I got pregnant from a 1 shot several days pre-ovulation.

So you really don't want to be doing that vitamin thing, mmmkay. Now what was this thread about again?
