Is the 100mg dosage per one capsule ?

Yes, the dosage of 100mg refers to the amount of Dehydroepiandrosterone (DHEA) in each capsule of the Life Extension DHEA - Optimal Hormone Balance supplement. The label suggests taking one to three capsules in the morning, but the exact number should be determined by blood testing and the advice of a physician. It's recommended to have DHEA serum blood tests 3 to 6 weeks after starting the supplement to optimize individual dosing.
