I checked my 25(OH)D with different D3s. And for me dry preparations take about (or more than double) the dose to stay at the same level.
I was pushing for this, but the minimum quantity required for a run of softgels is insane. It would have made the multi financially impossible.
I see. So I better stick with separate softgels of D3, K2, A's, tocotrienols and tocopherols taken separately. Though I only tested the difference of dry and oil based D3 - no reason not to believe this wouldn't apply to all other fat soluble, important and partly expensive vitamins to some extent as well.
.. and its not meant for the average consumer. its meant for the 'connoisseur'.
Hmm.. Am I an average consumer if I'm willing to take more efforts, sometimes pay a higher price to get supplements in their best absorbed forms? - I think it's more the other way around.
Using D3 as an example, throwing in another 1-2000IU pill is a pretty negligible expense. But taking bioavailability into account (especially if in dry form), isn't ≤1100 IU a little on the low side, for most?
no... 1100 is a well studied dose and will put most people into the low-mid range. there is no arbitrarily good amount of vitamin D to ingest. what matters is blood levels... therefor we went with a low dose and allow people to add on what they need.
Well. All reports of 'real people' I've read seem to need quite a bid more than 1100 IU for reaching an advantageous blood level. Would be worthwhile making a public poll of how much IUs, dry or in oil, to reach a specific range (don't have the time at the moment).
Personally I need 8000 IU in oil - double!!! in the dry form - D3 to reach the same level. Could there be any good reason to take thousand of IUs, because they're only half absorbed? Other than having to take it to be able to get an uniquely formulated multi?
From my perspective, if it is financially impossible to have the best forms, and most anyway have to supplement additionally for the fat-solubles, it would be better to leave those worse forms of fat-solubles out from the beginning and the price would instantly come down.
On the other hand, a truly 'complete' (as far as possible, given the different needs for D3) Multi, with all fat soluble vitamins in oil seems to me what is really missing on the market.
