Mixed

Once-daily 100 mg ubiquinone in a water-and-fat-soluble base at a fair price, though CoQ10's evidence for statin aches and blood pressure is weak.

Pros and cons

Magnesium (Glycinate)

  • Minimal formula: magnesium glycinate, a cellulose capsule and ascorbyl palmitate
  • GFCO certified gluten-free, vegan and free of common allergens
  • Flexible 120 mg capsules make dosing easy
  • Detailed in-house and outside lab testing disclosures
  • About $0.30 per 120 mg capsule, pricier than many glycinates
  • The four-capsule maximum (480 mg) exceeds the supplemental magnesium upper limit
  • No USP or NSF certification
  • Capsules are fairly long at 0.905 inches

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

Magnesium (Glycinate)

This is the cleanest, most allergy-friendly magnesium glycinate you can easily buy, with unusually detailed testing disclosures and a formula that is kind to sensitive stomachs. You pay a premium for that, so budget buyers can get similar magnesium for less, but for people who react to fillers or other forms it is worth the money.

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.
