- About $0.06 per day
- 1,000 mg dose stays well under the 2,000 mg upper limit
- Vegan, kosher and halal, made without major allergens

Our verdicts
Vitamin D3 2000 IU Softgels
For most adults who want a daily vitamin D supplement, this is the benchmark: a sensible 2,000 IU dose, USP verification and a price that is hard to beat. Vegetarians should choose a gelatin-free option, and people who already have adequate levels should not expect broader health effects.

Vitamin C-1000 Sustained Release
An inexpensive, well-made way to take 1,000 mg of vitamin C a day from a manufacturer with solid quality systems. Most people get enough vitamin C from food, so it suits heavy exercisers, smokers and people with low fruit and vegetable intake best; others can take it less often.
