 I'm taking a 25000IU dose once a week.
Do you think it's enough? I read articles saying that in the winter we must take 5000IU's a day with no problem.

You are better off with the 5,000IU daily than you are with a single dose of 25,000IU once a week. The body can only absorb a limited amount of a vitamin at one time. Taking massive doses at once can inhibit the absorption or utilization of vitamins. Therefore they are better taken in smaller frequent doses.

I was VERY low in vit D (10ng/ml) but now it's better. Around 35ng, still very low. Wich range is the best? Some studies say 50ng is ok, others 70...

Part of the problem is that different labs can have different standards depending on how they are making the measurements. So there is no simple answer.

And for the supplements, wich form? oil? powder? Oils often contain other substances like arachid oil, flavours...

I would go with powders. They are going to be a lot more stable than the oils. 

Also remember that many of the supplements on the market are inactive D₂, even if the front of the label says D₃. And even if they were to use D₃ it would be the inactive form. D₂ is converted in to D₃ by the liver then in to active D₃ by the kidneys. Therefore you should also be supporting the liver and kidneys with herbs like schisandra berry and licorice root.
