What kind of supplement has activated folate (folic acid) and is typically recommended over Folic Acid suppliments?

Green leafy plants. I'm more of an advocate of getting your vitamins from FOOD, not from a bottle - where the substances within have been processed. Folate (or folic acid) is found naturally in green leafy plants - the name actually derives from 'foliage' or 'leaves'. So I advocate eating fresh veggies/plants. That type of diet also provides different minerals, micronutrients, anti-oxidants, fiber etc. that you need.
