I've been vegan since 2002 and haven't taken B12 supplements regularly for at least 10 years. My doctor wanted me to get my level checked since I'm vegan and not taking supplements. I'm in the healthy range.
When taking "a lot" of Vitamin D, one should also take an adequate amount of Vitamin K2 and Magnesium. They work synergistically and will prevent leaching of calcium into the bloodstream.

"Overdosing D is virtually impossible", they say and sell 100 µg capsules in supermarkets.
Recommendation is however 10 µg and even that is seasonal.
