I have been supplementing with Nutrisorb A from Inter plexus ( retinol palmitate) with great results. I haven' used it in a long time since it's not available (I have contacted them and they said it will probably be ready for sale again from the beggining of the next year), so I am looking for another good vitamin A source. I have read here that Haidut has a good product Estroban that contains vitamin A and that health Natura also made one, both of then being retinyl palmitate. Is that correct? I was wondering on your thoughts on that form of vitamin A and why do you prefer it over retinol? I have always thought that retinol is way better form of vitamin A. The internet these days is full of retinyl supplements and it is very easy to find them as of retinol is nowhere to be found any more.
