Purchased Natures Bounty "Triple Strength Cranberry": 140mg Cranberry Concentrated Powder Blend (includes: 100mg ascorbic acid, 3 IU Vit E). 50:1 concentrate = 2000mg fresh cranberries.

Question: does this contain enough Vit C to = 1tsp Vit C if I administer 2 softgels daily? Or, should I still supplement an additional 1tsp of Vit C daily?
