    Would this supplement be more potent than nutrisorb A? And the best way to take this is drop on wrist and massage in?

    Similar question to above.
    I've read somewhere, about your MK4 supplement, that to achieve the same blood concentrations, one could use a smaller amount of the vitamin topically in DMSO than they take orally.
    Does this carry over to vitamin a as well? Could I use a smaller dose of retinil to achieve the same effects I do from Oral dose of vit a is?

    Retinil does not use DMSO, so the absorption is much lower through skin. However, given that vitamin A accumulates in the liver that lower topical absorption may still go a long way since even a high oral dose would deliver most of the vitamin to the liver and peripheral circulation. Don't know the exact ratio of topical-to-oral for vitamin A dissolved in water/ethanol but topical absorption is probably ~25% of the applied amount. And bioavailability from a large oral dose may be as low as 10%. So, an oral dose of 100,000 IU would be about the same as 40,000 IU topically. I am using these numbers just for convenience, not to suggest somebody should be taking that much.

    How long on skin to get this 80% absorption?

    Where do you see references to 80% absorption for Retinil?

    I hate liver, and I want to use Retinil to make up for the retinol I won't be getting from liver. Is there anything I'd be missing from liver apart from the copper, B12, folate, and retinol, and do you think a glandular would be more appropriate?

    Liver also has vitamins E, K and D, zinc, manganese, as well as some steroids (including thyroid). If you think you are good on these form other sources than I guess you can skip the liver.

    Thanks for the info; I didn't know about the steroids, but I'll give Retinil a shot.

    Try to find fresh liver in a local butcher, much better taste.

    Lamb and chicken liver also taste better than cow liver.
