Does 7-Keto® have any effect on T3, one of the thyroid hormones?
No. One clinical study for weight loss showed a slight elevation in T3 (within the normal range) in the subjects taking 7-Keto®. Subsequent clinical studies have shown no effect on T3 compared to placebo or compared to baseline values in the subjects taking 7-Keto®. Therefore, there is no convincing positive or negative effect on T3 in individuals taking 7-Keto® at 200 mg per day.
