Pros and cons
Vitamin D3 2000 IU Softgels
- USP Verified for ingredients, potency and manufacturing
- 2,000 IU of D3 is half the adult upper limit
- About $0.06 per day
- Small softgel with an oil base that supports absorption
- Gelatin shell, so not vegetarian
- Soybean oil base may not suit people avoiding soy-derived ingredients
- No vitamin K2 for those who want a combined formula
Vitamin B-12 1,000 mcg
- About $0.05 per day
- 1,000 mcg dose compensates for limited absorption of oral B12
- Small, coated tablets that are easy to swallow
- Non-GMO, gluten-free and suitable for vegetarians
- No USP or NSF certification
- Brand site shows an outdated %DV and the Amazon listing has copy errors
- Far more B12 than people with normal levels need
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.
Full review
Vitamin B-12 1,000 mcg
For most people who need extra B12, this is the simplest and cheapest effective option: a well-studied form at a dose that compensates for limited absorption, in a tablet anyone can swallow. It lacks independent certification and its listings are sloppy, but the formula itself is sound.
