Yes, Cholecalciferol is D3... It is in most supplements now, as they have been reformulated. It is also now in milk and dairy products (which used to be D2).
D2= ergocalciferol and remains on RX-- this is an old historical product that has never been re-evaluated. So the 50,000IU given by doctors as an RX is mostly ineffective today --according to new studies.
The general rule for D3 supplements is 1000IU D3 daily for every 10 points you need to raise. So use a level of 50 as your goal.
At 38, you may only need 1000 IU D3 daily.
So your NatureMade is fine.
