What 'energy-boosting' supplements really contain

Unsafe hidden ingredients are cause for concern, say experts

Adrenal support supplements sold online or over the counter as energy or metabolism boosters may contain unlisted and potentially unsafe hidden ingredients, experts warn.

Warning sign

Lab tests of 12 popular dietary supplements marketed for so-called adrenal fatigue found that they all contained the thyroid hormone triiodothyronine, and seven had at least one steroid hormone.

The most commonly detected hormone was pregnenolone, which was in five products.

Budesonide, androstenedione, 17-OH progesterone, cortisone and cortisol were also found, in order of prevalence.
