Adverse reactions and side effects of 7-keto-DHEA may include but are not limited to gastrointestinal upset/nausea, headache, decreased hemoglobin and hematocrit levels, sensitivity to mosquito bite, vertigo, and increased serum triiodothyronine (T3) levels.[6][16][17] Short-term studies in preclinical models revealed no adverse effects with 7-keto-DHEA.[20][21][22] Short-term studies in humans 7-keto-DHEA, administered as 3β-acetyl-7-oxo-DHEA, is safe and well tolerated.[6] The long-term safety of 7-keto-DHEA, in any form, or its metabolites have not been conducted. A safety study of 7-keto-DHEA administered as the acetyl ester (dose escalation: 50 mg/day for 7 days, 100 mg/day for 7 days, and 200 mg/day for 28 days) concluded that 3-acetyl-7-oxo-DHEA is safe and well tolerated.[6] In this study of 22 healthy male participants, 82% of participants in the 7-keto-DHEA group (n=16) and 100% of those in the placebo group (n=6) reported mild adverse events. The most common adverse event was gastrointestinal upset, occurring in 18% of the 7-keto-DHEA recipients and 33% of the placebo recipients. Headaches (n=4) were reported in the 7-keto-DHEA group. Two adverse events were deemed as possibly related to 7-keto-DHEA therapy, decreased hemoglobin and hematocrit levels (n=1) and heightened sensitivity to mosquito bite (n=1). Participants who received the 7-keto-DHEA acetyl ester also had significantly decreased blood pressure during treatment compared with their baseline values.[6] Nausea and vertigo and increased serum triiodothyronine (T3) levels have also been reported as adverse events and side effects, respectively, related to 7-keto-DHEA supplementation.[17][16]
