Keto 7 Complex
Also known as: 7-keto-dehydroepiandrosterone, Keto 7 Complex, 7-keto-DHEA
Overview
7-keto-DHEA is a naturally occurring metabolite of dehydroepiandrosterone (DHEA), a steroid hormone produced by the adrenal glands. Unlike DHEA, 7-keto-DHEA is not hormonally active, meaning it does not convert into sex hormones like testosterone or estrogen. It is primarily used as a dietary supplement to support weight management by influencing metabolism. Its purported ability to enhance thermogenesis without hormonal conversion makes it an attractive option for individuals seeking fat loss support. Research on 7-keto-DHEA is moderately mature, with several randomized controlled trials and at least one systematic review available, indicating its potential to increase resting metabolic rate and modestly reduce body fat.
Benefits
The primary benefit of 7-keto-DHEA is its ability to increase resting metabolic rate (RMR). Studies have shown an increase in RMR ranging from approximately 1.4% to 7.2% compared to placebo in controlled trials, which suggests a potential for increased calorie expenditure. While statistically significant (p < 0.05), the clinical impact on long-term weight loss is considered modest and requires further investigation. Some research also reports reductions in body fat percentage and body mass index (BMI), though the effect sizes vary. These benefits are most relevant for overweight or obese adults seeking weight loss support. Secondary effects, such as potential improvements in immune function and antioxidant status, have been suggested but lack robust clinical confirmation. Effects on metabolic rate have been observed within weeks of supplementation, but longer-term outcomes on weight require more extensive study.
How it works
7-keto-DHEA is believed to enhance thermogenesis, the process of heat production in the body, by increasing the activity of specific enzymes involved in fat metabolism. These enzymes include mitochondrial glycerol-3-phosphate dehydrogenase and 18-hydroxylase, which contribute to increased energy expenditure. A key aspect of its mechanism is that it does not convert into testosterone or estrogen, thus avoiding hormonal side effects. It may also modulate thyroid hormone activity, which plays a crucial role in regulating the basal metabolic rate. The supplement is absorbed orally, though the specifics of its bioavailability are not yet fully characterized.
Side effects
7-keto-DHEA is generally considered safe when taken at studied doses, typically up to 200 mg per day, with a low incidence of reported adverse effects. Mild gastrointestinal discomfort has been occasionally reported, but common side effects occurring in more than 5% of users are rare. High-quality studies have not documented any significant drug interactions or contraindications. However, long-term safety data are limited, and caution is advised for pregnant or breastfeeding women, as well as individuals with pre-existing hormone-sensitive conditions due to insufficient research in these populations. It is important to consult a healthcare professional before starting supplementation, especially if you have underlying health conditions or are taking other medications.
Dosage
The minimum effective dose for 7-keto-DHEA appears to be around 100 mg per day, based on findings from randomized controlled trials. The optimal dosing range typically falls between 100 to 200 mg per day, often recommended to be split into two doses for consistent effects. While doses above 200 mg per day have been less studied, the maximum safe dose has not been definitively established. The timing of supplementation is flexible, but taking it with meals may improve absorption. No specific cofactors are required to enhance its effects, though general nutritional support can complement its metabolic benefits. It is always advisable to adhere to product label instructions or consult a healthcare professional for personalized dosage recommendations.
FAQs
Is 7-keto-DHEA hormonal?
No, 7-keto-DHEA is a metabolite of DHEA but does not convert into sex hormones like testosterone or estrogen, thus it is not considered hormonally active.
How soon will I see effects?
Increases in resting metabolic rate can be observed within weeks of consistent supplementation. However, noticeable weight loss effects may take a longer period to manifest.
Is it safe for long-term use?
While short-term use of 7-keto-DHEA appears safe at recommended doses, comprehensive long-term safety data are currently limited. Consult a healthcare professional for extended use.
Will it cause side effects?
Side effects are uncommon and generally mild if they occur, with occasional reports of mild gastrointestinal discomfort. It is well-tolerated by most individuals at studied dosages.
