Consumer labs hasn't tested MultiV!
It largely depends on what forms were Vitamins and minerals made.
For example... Vitamin D is best to take as D3 (not D2).
Vitamin C absorption is only about 20% if done as ascorbic acid and other forms... the only form of Vitamin C which seems to be best absorbed is Liposomal Vitamin C which seems to achieve about 95% absorption into the body due to Liposomes which protect C from the harshness of the gut and deliver it to the cells.
In terms of Zinc... only Zinc Picolinate demonstrated in peer-reviewed studies elevated levels of Zinc after long term supplementation - no other form of Zinc did that.
In addition, Copper Sebacate also showed that it seems to be the most bioavailable form - though the info on this is a bit sketchy.
Additionally, Vitamin K2 is best taken as MK-7 form ... all other forms of K are not really useful to the body.
Selenium seems to be best absorbed as L-Selenomethionine form.
B vitamins in most multivitamins are well absorbed if I'm not mistaken.
I saw elevated Vitamin levels across the board after using NOW FOODS ADAM Superior Men's Multi (180 Softgels).
But I also made sure to take Zinc Picolinate 50mg separately as well as Copper Sebacate (3mg).
Even this multi-vitamin that I'm taking is not really using the best possible forms of all vitamins or balanced dosages (for example, most B vitamins are exceedingly high - they would do ok to be reduced by about 20% AT LEAST - leaving room to enhance the dosage of K2 as MK-7, then switch Zinc to Picolinate form and increase the dosage to say 30mg... accompanied by 3mg of copper, etc. - although, copper and zinc are best taken separately, I've noticed these effects on myself)
I'd love to try to do that though - to make a multivitamin with only the most biovailable forms which were checked to raise levels in the body by peer-reviewed studies.
Actually, you can do the check on google and pubmed.
They feature A LOT of this peer-reviewed data on which forms seem to be most bioavailable.
You can input on google something like:
Zinc picolinate bioavailability pubmed
Which leads to the first result being this:
Alternatively, I guess you can check which forms of vitamins and minerals are in a specific multivitamin (before buying them) and then check peer-reviewed studies
