Higher score

Pros and cons

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

Iron Bisglycinate

  • Iron amino-acid chelate, a form NIH says may cause fewer GI side effects
  • NSF Certified for Sport
  • 25 mg dose sits below the 45 mg upper limit
  • Small 18 mm capsule with a short ingredient list
  • About $0.27 per day, more than generic ferrous sulfate
  • Some users still report nausea on an empty stomach
  • No vitamin C or other cofactors included
  • Not appropriate without a confirmed need for iron

Our verdicts

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.

Iron Bisglycinate

If you have documented low iron and struggle with conventional iron pills, this is one of the best-tolerated and best-verified options available, at a fair premium. It is not something to take without a reason: check ferritin first, and space it from calcium, thyroid medication and zinc.
