This is just another lifestyle thing that is difficult to interupt fully. One thing I don't like about multi's is what really is the RDA of each component. For example, many multi's have vitamin D in them. The RDA is 200iu (some have 400iu). Well, now it is recommended to take 800iu and if I only took 800iu, I am sure that I would not be in the normal range (blood work wise) for vitamin D as I take about 4200iu per day and my levels are 46 (range is 32 - 100) so obviously, for me, my RDA is much higher (blood range in my family is a problem and those who are low or non-existant did get bc so I watch my daughters closely). So, my point is what is my folic acid requirement and if by taking a multi am I overdosing on some stuff and underdosing on others. I think if you eat a really balanced diet, then supplementing with Vitamin D, Omega 3 and perhaps some oddities like mushroom and curcumin would be just fine.

One day we will be like Star Trek where instantly you will be told what to do in regard to your unique genotype.
