Pros and cons
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- Brand site shows an outdated %DV and the Amazon listing has copy errors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
Ultra CoQ10 100 mg Softgels
- Solubilized formula; the NAD found a reasonable basis for its higher-absorption claim versus standard powdered CoQ10
- Short, fully disclosed label: 100 mg CoQ10 plus vitamin E, no proprietary blend
- Inexpensive at about $0.29 per day from qunol.com
- Brand states third-party testing and cGMP manufacturing; labeled gluten-free
- 100 mg is below the 300 mg a day used in the key heart-failure and migraine trials
- Evidence for statin muscle aches is mixed and for blood pressure is negative
- Testing results are kept confidential, and the #1 cardiologist claim rests on a survey about the form, not the brand
- Bovine gelatin, polysorbate 80 and sorbitol; some buyers find the one-inch softgel large
Our verdicts
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.
Full review
Ultra CoQ10 100 mg Softgels
Qunol Ultra is a well-made, inexpensive way to take 100 mg of CoQ10 once a day, and solubilized formulas like this one generally absorb better than plain powdered CoQ10. The weak link is CoQ10 itself: evidence is mixed for statin aches and negative for blood pressure, and the heart-failure and migraine trials used 300 mg a day. Take it with food, and talk to your clinician first if you use warfarin or insulin.
