7-alpha-hydroxy-DHEA is a by-product of dehydroepiandrosterone (DHEA) that is formed in the body. DHEA is a “parent” hormone produced by glands near the kidneys.
How does it work?
There is interest in using 7-alpha-hydroxy-DHEA to prevent aging because levels of this substance drop with age. Some people think replacing it might promote youthfulness. 7-alpha-hydroxy-DHEA might also stimulate the immune system and might act like an antioxidant.
Insufficient Evidence to Rate Effectiveness for...
- Promoting weight loss.
- Increasing lean body mass.
- Building muscle.
- Boosting the activity of the immune system.
- Improving memory.
- Preventing aging.
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
The appropriate dose of 7-alpha-hydroxy-DHEA depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for 7-alpha-hydroxy-DHEA. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
