Knowing that 1.5 mcg + 1% are absorbed, to calculate how much mcg you must take to absorb 7 mcg you must do:brimstoneSalad wrote:Any idea what kind of intake is needed to reach 7 mcg, since it's non-linear?
Maybe 600 mcg?
7 mcg - 1.5 mcg = 5.5 mcg
5.5 mcg * 100 + 1.5 mcg = about 550 mcg
The funny part about this is, if you take only 1.5 mcg at a time, you should absorb 1.5 mcg. If you take 250 mcg at a time, you absorb only 4 mcg.
Remember that it's approximated.
Definitely true. Better to take a supplement and be sure in those cases.brimstoneSalad wrote:But, it doesn't hurt to supplement, and I want to be able to have a vitamin that I know I can afford to eat a little junk food on now and then if I need to; and something I can recommend to others, who might be junk food vegans, or not understand the whole Omege3:6 ratio concept.
See the link in the last post I made- that person was talking about how she eats way too much Omega 6, but isn't willing to change her diet. I don't want people like that to get sick.
It's much easier to say "take this" rather than teach somebody nutritional science, or convince somebody who knows nutritional science but is obsessed with junk food to change his or her diet... I've known people who knowingly eat themselves to death.
But at the same time... if it tastes really bad, people won't take it, so including it would be counter-productive if that issue can't be solved.
I agree. That was only for those who can/want to have a well balanced diet.brimstoneSalad wrote:Choline isn't actually as easy, unless you eat a lot of soy and cruciferous vegetables.thebestofenergy wrote: Regarding Choline, you can have enough of it with a correct diet[...]Same goes for Zinc[...]B2[...]iodine[...]
I currently don't take supplements for these.
I tend to eat a lot of soy, so I probably get enough most of the time. I could afford to get more, though- as can most people.
Zinc, B2, iodine... that's all true.
A carefully planned vegan diet can provide everything except B-12. BUT that's not the point of a multivitamin.
A multivitamin is back up, it's a safety net that helps prevent malnutrition when you fall short of that carefully planned diet.
If I'm a poor college student and I eat ramen for a month, I'll almost keel over dead... but ramen and something like this... and I might live to see the next paycheck.
This wouldn't be needed or useful for people eating the ideal vegan diet. But for the rest, and that is most, vegans who eat less than an ideal diet, it could make a big difference.
The point of a genuinely useful vegan multivitamin is to have something to recommend to people who aren't eating the perfect diet, and something that can make that more sustainable and prevent serious nutritional problems down the line.
I thing that a mega-supplement multivitamin with all of those things included would cost a lot.
Probably in the future, when the number of vegans will increase, they will make one for a low price. Besides, that multivitamin would be really useful for non-vegans aswell.
EDIT: I should add that, in fact, you can take 2-3 mcg of cyanocobalamin twice a day, distant from one another, since it's absorbed 1.5-2 mcg at a time.
