I used to take a multivitamin called Usana. I believe the vitamin for my age group 15-21? was called something like Body Rox. My sports medicine guy recommended it to me and told me his friend started it. He showed me a study that was done on like a hundred common multivitamin products where they gave a score to them on a scale of 0-1.0 based on bioavailability, toxicity, what vitamins it had in it and if it had enough, etc. It had like 20 things the rating was based on. I don’t know the details of the study but most of the common multivitamins ppl take like Centrum, Mega-Men, etc. were rated very very low like 0.2 . Usana was near 0.9 and I believe Twinlabs might have been up there also around 0.8. Not sure, I’ll try to find the study online for you though. Don’t know if Usana has a website or what but it was good stuff. I slept a lot better and felt better during day (placebo effect?). Might be worth looking at though.[/quote]
bkerne,
The study you mentioned would definitely be useful to this and future multi discussions. Let us know if you’re able to find it. Thanks.
I have noticed a lot of people are taking multi-vitamins without iron. Is their a reason for this?
I am using Twinlab Daily Two Caps with iron. I have always heard that multiple servings per day result in better utilization of nutrients as compared to one mega dose.
For bioavailability, the best bet is a chewable childrens vitamin chewed with a meal, half with breakfast and half with your evening meal.
As for iron, it is toxic, so if you do lots of beef, you probably wouldn’t need to supplement with iron. Don’t supplement with more than 200% of the RDA with iron.
As far as bioavailability goes whatever your brand name is, if it is in tablet form, then it should not be on this list. Tablets are the absolute worst way to take in a nutrient. The best would be a whole form form like a greens powder. A good greens powder with a blend of the three cereal grasses and chlorella, etc. would contain every nutrient essential for life.
