7 keto DHEA is a dietary supplement that is manufactured by a company called InterHealth.  InterHealth Nutraceuticals develops, researchers and sell branded dietary supplements.  They sell their products worldwide to manufacturers and contract packagers to make finished dietary supplements to be sold to consumers.  They do not sell to consumers, only to packagers.

Here is the brand that I recommend.

Jarrow Formulas 7-Keto DHEA, Enhances Metabolism, 100 mg, 30 Caps

7 Keto DHEA is used as a weight loss supplement.  This is a patented and BRANDED ingredient and unfortunately one of the most counterfeited by the Chinese.  Thus you have to be very, very careful when you buy this product.

What is 7 Keto?

7 Keto DHEA is a metabolite that has been extensively studied in animals and humans for various benefits including weight, metabolic rate, memory and others. 7-Keto® is natural and is a metabolite of DHEA.    7 Keto promotes weight and fat loss and maintains metabolic rate.  7 Keto is patented for metabolic modulation and is has many published research studies showing that 7 Keto is almost 3 times more effective than exercise and dieting alone.

In another clinical study, 7 Keto DHEA decreased weight by about 6 pounds after 2 months.  Subjects participated in high-intensity exercise and followed a very good diet.  Thus you have to be realistic when you take this product and you cant be on a bad diet.  You have to exercise and eat right.  Avoid sugars, transfatty acids, nitrates, and processed carbs.

Research for 7 Keto DHEA




The purpose of this study was to determine the effects of 3-acetyl-7-oxo-dehydroepiandrosterone (7-oxo-DHEA) in healthy overweight adults.


In a double-blind, placebo-controlled protocol, 30 adults (28 women and 2 men; mean age, 44.5 ± 11.5 years) with a mean body mass index of 31.9 ± 6.2 kg/m2 were randomly divided into 2 groups of 15: Group 1 received 7-oxo-DHEA 100 mg twice daily and Group 2 received placebo for 8 weeks. All subjects participated in an exercise training program 3 times per week. Each exercise session consisted of 60 minutes of cross-training (aerobic and anaerobic exercise) under the supervision of an exercise physiologist. In addition, each subject was instructed to follow a diet of ~1800 kcal/d (20 kcal/[kg · d]) by a registered dietitian. Subjects received biweekly dietary counseling to encourage compliance. Study participants underwent serum multiple-assay chemistry testing, as well as body composition, blood pressure, and dietary analysis at baseline, week 4, and week 8.


Of the 30 subjects who entered the study, 23 completed the 8-week protocol. Seven subjects dropped out for personal reasons unrelated to the study. Group 1 lost a significant amount of body weight compared with Group 2 (−2.88 kg vs −0.97 kg; P = 0.01) over the 8 weeks. Group 1 also achieved a significant reduction in body fat compared with Group 2 (−1.8% vs −0.57%; P = 0.02). The rate of change in body fat per 4-week interval in Group 1 was 3.1 times that in Group 2 (−0.88% vs −0.28%; P < 0.01). Group 1 also experienced a significant increase in triiodothyronine (T3) levels compared with Group 2 over the 8-week study period (+17.88 ng/dL vs 2.75 ng/dL; P = 0.04). There were no significant changes in levels of thyroid-stimulating hormone (TSH) or thyroxine (T4) in either group. In addition, no significant changes were observed in vital signs, blood sugar, testosterone and estradiol levels, liver and renal function, or overall caloric intake during the study. No subjective adverse effects were reported throughout the study.


The results of the study suggest that 7-oxo-DHEA combined with moderate exercise and a reduced-calorie diet significantly reduces body weight and body fat compared with exercise and a reduced-calorie diet alone. In addition, 7-oxo-DHEA significantly elevated T3 levels but did not affect TSH or T4 levels, indicating that it does not adversely affect thyroid function in the short term.

The effect of 7-Keto Naturalean™ on weight loss: A randomized, double-blind, placebo-controlled trial


Background: A natural metabolite of dehydroepiandrosterone (DHEA), 3-acetyl-7-oxo-dehydroepiandrosterone (7-oxo-DHEA), has been shown to be effective in enhancing weight loss when combined with a diet and exercise program.

Objective: This study assessed the effects of a formula containing 7-oxo-DHEA, l-tyrosine, asparagus root extract, choline bitartrate, inositol, copper gluconate, manganese, and potassium iodide (7-Keto Naturalean™) on weight loss, body composition, and basal metabolic rate (BMR) in overweight patients following a weight-reduction diet and exercise regimen.

Methods: In this prospective, randomized, double-blind, placebo-controlled trial, healthy, overweight adults were given 7-Keto Naturalean (200 mg/d) or a placebo of maltodextrin and followed a calorie-restricted diet (105 kJ/kg) and an exercise program for 8 weeks. Body weight, body composition (by bioelectric impedance), and BMR (by indirect calorimetry) were measured at baseline, week 4, and week 8. A thyroid panel was done at baseline and week 8.

Results: Of 35 healthy, overweight adults enrolled, 33 completed the study (12 men, 21 women; age, 40–69 years; body mass index [BMI], 27.0–42.7 kg/m2). Patients taking 7-Keto Naturalean lost significantly more weight after 8 weeks than those taking placebo (mean ± SD loss, 2.15 ± 2.38 kg and 0.72 ± 2.12 kg, respectively) (P = 0.038). The change in BMI in the 7-Keto Naturalean-treated group was significant compared with the change in the placebo group (mean ± SD decrease, 0.71 ± 0.79 kg/m2 and 0.01 ± 1.05 kg/m2, respectively) (P = 0.036). There were no other statistically significant differences in any of the other measured variables. 7-Keto Naturalean was well tolerated, and there were no significant adverse events.

Conclusion: In this select population, 7-Keto Naturalean combined with a reduced-calorie diet and an exercise program resulted in a significant weight loss compared with diet and exercise alone.
