7-Keto DHEA


7-Keto DHEA, or 7-Keto DHEA is named after the compound 3-acetyl-7-Keto dehydroepiandrosterone, a substance found naturally in the body that is metabolized from the hormone DHEA (Marwah et al., 2002). Studies have indicated that 7-Keto is stable (does not convert to testosterone or estrogens), safe and effective as part of a weight loss program (Lardy et al., 1995, Davidson et al., 2000; Humanetics Corps, 2005, respectively). In fact, 7-Keto has shown in studies to activate 3 thermogenic enzymes, known to help the body convert stored fat to energy (Zenk et al., 2007, 2004). But since levels of DHEA and 7-Keto decline in our body with age, supplementation with 7-Keto helps maintain healthy levels for weight management (Lardy et al., 1998; 1995).*

7-Keto DHEA turns on fat burning mechanism and supports sustained energy. Take 1-2 capsules a half hour before meals.*

7-Keto DHEA has no fillers, binders, or other additives, it is purely 7-Keto. 


In the pre-clinical development (see Bobyleva et al., 1993), 7-Keto was found to behave similarly to the thyroid hormone which also activates the thermogenic enzymes in our body. 7-Keto DHEA showed similar ability to restore mitochondrial function (Bobyleva et al., 1997) and support weight loss by enhancing thermogenic enzyme activity.*

Clinical trials have been ongoing since 1999, in specific, two randomized, double-blinded, placebo-controlled (“RDBPC”) in 1999 and 2000 have shown that 7-keto significantly increased weight loss over a period of eight weeks compared to the placebo group (Zenk et al., 2002; see also Kaiman et al., 2000; Bobyleva et al., 1997).*

Thermogenesis is the creation of heat in the body; a form of energy that is produced when we eat and metabolize food. Kaiman et al. (2000; see also Zenk et al., 2002) conducted a RDBPC study of 30 healthy overweight adults for 8 weeks. The group taking the supplement of 7-Keto showed a significantly reduced body weight. The study included exercise (three times a week) and a reduced caloric diet for both placebo and 7-Keto groups. Zenk et al. (2004; 2007) similarly found that 7-Keto increased metabolism, which is shown in research to promote weight lose and support the management of weight overall. By up-regulating the activity of fat burning enzymes (the thermogenic effect), energy expenditure is increased, enhancing the process of weight loss (Gomez et al., 2002).*

Moreover, 7-Keto DHEA is also shown in research to enhance memory in young and old rats (Shi et al., 2000), immune modulation in older men (Hampl et al., 2000), and significantly enhance depressive symptoms and hypo-immunity of mice when induced by chronic mild stress (Liu et al., 2003).*

BioImmersion's 7-Keto is encapsulated without any other additives (binders, fillers of any kind). It is in its pure form, active, powerful, and at the same time, gentle.
