Any brand will do: Counter to what a salesperson might tell you, there's not much money to be made selling vitamin D. As long as the label has a USP DSVP symbol on it, you're pretty assured of its quality. So don't buy fancy brands/names - just make sure it's D3, not D2. For most, 1,000-2,000units each day should be fine. Take enough to bring your 25OH vitamin D above 30ng/mL. Don't check 1,25 diOH vitamin D.
