Any details on the “micronutrients and vitamins” they are studying?
Interventions
The active intervention (micronutrients) consisted of capsules containing a blend of ingredients comprising all vitamins and known essential minerals, plus amino acids and antioxidants. A total of 9 to 12 capsules per day accumulated to doses above the Recommended Dietary Allowance (RDA) but below the Upper Tolerable Intake Level (UL). The formula, Daily Essential Nutrients, was developed and provided without cost by Hardy Nutritionals (Raymond, AB, Canada; www.hardynutritionals.com). Hardy Nutritionals also provided visually identical capsules for placebo containing cellulose filler and 0.1 mg of riboflavin per capsule to mimic the color of urine as when supplemented with B-vitamins (see Tables S2 and S3, available online, for complete ingredient list).
