DHEA is a naturally occurring hormone being synthesized by the adrenal glands. It is critical to consult with your prescribing physician if you are taking any psychotropic medication. We mentioned that, as we age, DHEA levels can decrease. The research available on 7-keto-DHEA has not shown an increase in muscle mass, strength, testosterone levels or any sex hormones for any section of the population. Cookies collect information about your preferences and your devices and are used to make the site work as you expect it to, to understand how you interact with the site, and to show advertisements that are targeted to your interests. People with severe diabetes should not use DHEA; others should monitor blood sugar levels carefully. Keep in mind that supplements haven't been tested for safety and dietary supplements are largely unregulated. Marenich LP (1979). Taking DHEA orally will usually restore the level of DHEA in the blood to a youthful level. How was this verified? The information provided by this website has not been evaluated by the Food and Drug Administration. In the year 1998, the Journal of Steroids published a landmark study proving that 7-keto-DHEA can cause dramatic fat loss in test subjects. Greater amounts of thermogenesis boost the bodys metabolic rate which increases the conversion of stored fat into energy. This, however, may not be the same for orally ingested 7-keto-DHEA due to the lack of studies available showing a similar result. 7-keto DHEA plays a role in reducing cortisol, the main catabolic hormone in the body. Our website is not intended to be a substitute for professional medical advice, diagnosis, or treatment. [25], 7-keto supplementation may have a small enhancement on thyroid hormones, Application of 25mg 7-keto via cream for 8 days in otherwise healthy males has been associated with a reduction in Luteinizing Hormone (LH) by 46% and Follicle Stimulating Hormone (FSH) by 25% when measured the day after the cream was starting to be appled, but were not reliably reduced in 100 days of followup (with a slight increase in FSH on day 100). They act as messengers in the body that help control and coordinate several internal activities. That's because DHEA is a "prohormone" -- a substance that can increase the level of steroid hormones such as testosterone. [34] One study suggests a spike n 7.2% of the metabolic rate, but this study used a subactive dose of 7-Keto (17mg) paired with a variety of stimulatory compounds (Yerba Mate at 167mg, piper nigrum at 1.7mg, 50mg Coleus Forskohlii, 100mg Citris Aurantium at 6% Synephrine, and 233mg Guarana at 22% caffeine).

However, research suggests that testosterone replacement therapy is a more effective therapy than DHEA for: Studies done on whether taking DHEA can increase testosterone are often limited with mixed results. Even more alarming, one study shows that when 7-keto-DHEA was applied via a skin patch it actually decreased testosterone and free testosterone levels. Lardy H, Henwood SM, Weeks CE. 2. These are glands just above your kidneys. One of the milder side effects of DHEA is mild acneiform dermatitis. In people with bipolar disorder, DHEA should be used with caution and only in low doses because it can exacerbate mania, irritability, and aggression. [6][7], The World Anti-Doping Agency lists 7-keto-DHEA as a prohibited anabolic agent. As for other conditions, both National Standard and the NIH say the evidence is unclear whether DHEA has any significant benefit in treating conditions such as: Both agencies also say there is little evidence to support claims that DHEA has value in treating conditions such as fibromyalgia, addressing issues with memory or muscle strength, or enhancing and stimulating the immune system. 2002 May;87(5):2225-31. There are currently no studies using supplementation to assess this claim, In rats conditioned to respond to alcohol ingestion (operant conditioning), acute consumption of 7-keto (10-56mg/kg) was able to reduce responding to alcohol, suggesting of possible anti-alcoholic effects; these effects were also noted with DHEA (10-180mg/kg). Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit. 7-oxodehydroepiandrosterone (7-oxo DHEA and more commonly known as the brand name 7-keto) is one of three oxygenated metabolites of dehydroepiandrosterone, and these three oxygenated metabolites interconvert with one another but do not convert back into parent DHEA; 7-keto supplementation is a way to get these three oxygenated metabolites without using DHEA supplementation, and DHEA may form . (4-5), In fact, 7-Keto was 2.5 times more active than DHEA at inducing the activity of thermogenic (calorie burning) enzymes in later work by Marenich. 7-keto-DHEA is one of the best supplements for boosting testosterone levels. [10], 7-keto and the oxygenated DHEA metabolites interconvert using some of the enzymes used in cortisol metabolism (11-HSD1,[10] which also reduces cortisone into cortisol[37][38]). [35], One study using 7-keto at 200mg (alongside green tea catechins, chromium, Vitamin D, Vitamin C and calcium) during a period of caloric restriction in obese adults noted that the supplement was associated with a 3.4% increase in metabolic rate (59+/-118kcal) while placebo decreased 3.4%. While consumers face such risks when purchasing any dietary supplement, these risks may be of greater magnitude when buying products containing a variety of ingredients and marketed for bodybuilding or weight loss. Verifiable Science. [26], Endogenous 7-keto and the oxygenated DHEA metabolite appear to be reduced in the brain during a menstrual cycle, and are thought to be related to mood changes (as they are neurohormones). These side effects include: Taking DHEA supplements in high doses for extended periods of time is not recommended. Safety and pharmacokinetic study with escalating doses of 3-acetyl-7-oxo-dehydroepiandrosterone in healthy male volunteers. DHEA supplementation may help with depression, but it has a long list of potential side effects and drug interactions. However, 7-Keto has also been shown to be effective when used for weight loss. Given the potential health risks, it's important to take caution when using DHEA supplements for any purpose. There are risks associated with using any pre-steroid enhancer. Weeks C, Lardy H, Henwood S. Preclinical toxicology evaluation of 3-acetyl-7-oxo-dehydroepiandrosterone (7-keto DHEA). . The advantage of 7-keto-DHEA is that, unlike its "parent" hormone, it does not affect sex hormone levels in the body. Steroids 1998;63:158-65. Can They Increase Muscle?

Overview of 7-Keto DHEA Capsules Dosage Strengths of 7-Keto DHEA Capsules. 7-Keto exhibits a functional profile that is distinct from other forms of DHEA. 1 Star Davidson MH, Weeks CE, Lardy H, et al. A safety study in humans has shown that 7-KETO did not raise estrogen or testosterone levels or produce any other negative effects at levels up to 200 mg per day for eight weeks.3 Short-term animal studies also revealed no adverse effects with large amounts of 7-KETO.4, 5, 6 However, the long-term safety of 7-KETO for humans has not been demonstrated, and, because it is chemically related to steroid hormones, the potential for adverse effects must be considered. In some cases,the product may deliver doses that differ from the specified amount for each herb. DHEA may interfere with a wide variety of prescription medications, over-the-counter medications, and other herbal supplements. Its use is banned by sports organizations such as the National Football League, Major League Baseball, and the National Collegiate Athletic Association. Leading researchers (Mischoulon and Rosenbaum) recommend that people taking DHEA should be regularly monitored for occasional development of aggressive or disinhibited behavior. Clin Invest Med. A safe and more active form of an essential . Precursors are substances that are converted by the body into a hormone. Namely, the mitochondrial Glycerol-3-Phosphate Dehydrogenase, Malic Enzyme and Fatty Acyl CoA Oxidase . By clicking Subscribe, I agree to the WebMD, A Look at Alli (Orlistat) for Weight Loss, Slowing natural changes in the body that come with age, Myalgic encephalomyelitis/Chronic Fatigue Syndrome, Aggressive behavior, known as "roid rage", Mood swings and other psychological symptoms, Many of the claims for DHEA involve serious medical conditions. [16][17] Due to the irreversibility of the Oxysterol 7-hydroxylase and CYP3A4/5 enzymes, there is no conversion of these three molecules back into parent DHEA, and the metabolism of DHEA into androgenic or estrogenic precursors (into androstenedione via 3-HSD) cannot occur following 7-keto supplementation. DHEA (dehydroepiandrosterone) is used by the body as a building block in the production of estrogen, testosterone, and progesterone. 7-Ketodehydroepiandrosterone (7-keto-DHEA,7-oxo-DHEA), also known as 7-oxoprasterone, is a prohormone produced by metabolism of the prohormone dehydroepiandrosterone (DHEA). 7-keto-DHEA is formed from dehydroepiandrosterone (DHEA) in the body. Havlikova H, Hill M, Hampl R, Starka L. Sex- and age-related changes in epitestosterone in relation to pregnenolone sulfate and testosterone in normal subjects. DHEA (5-Dehydroepiandrosterone) is a natural steroid produced in the adrenal glands, the gonads and the brain. In addition, DHEA is often touted as an alternative to testosterone replacement therapy. Its external administration also helps in the treatment of systemic lupus erythematosus, osteoporosis, Addisons disease, schizophrenia, multiple sclerosis and slowing down Parkinsons disease. Adrenal glands are the endocrine glands located above the kidneys which synthesize hormones related to stress. Studies show that in certain cases, DHEA might contribute to liver damage or even liver cancer. By the age of 50, our production is only half of our youth. Additionally, there's some concern that DHEA supplements may be harmful to people with conditions like depression, bipolar disorder, diabetes, heart disease, and liver disease, as well as those with or at risk for hormone-sensitive conditions like prostate cancer. One of these supplements is 7-keto-dehydroepiandrosterone (7-keto-DHEA) . ", National Center for Complementary and Alternative Medicine: "Menopausal Symptoms and Complementary Health Practices. It is twice as effective as DHEA. [1], 7-oxo-DHEA is even more effective than DHEA for inducing heat production (thermogenesis). Using DHEA with this sedative might increase the effects of this drug, causing excessive sedation and . [30], In regards to activation of 'thermogenic enzymes' (mitochondrial sn-glycerol-3-phosphate dehydrogenase and cytosolic malic enzyme, their induction decreasing efficiency of the TCA cycle and acts as an uncoupling agent[6][31][32]) 7-keto as well as the similar structures 7-hydroxyDHEA and 7-hydroxyDHEA are all active, although 7-keto moreso; DHEA per se is ineffective. Effect of acute DHEA administration on free testosterone in middle-aged and young men following high-intensity interval training, Dehydroepiandrosterone in the treatment of erectile dysfunction: a prospective, double-blind, randomized, placebo-controlled study, Decreased fat mass andobesity prevention. [41], At least one study has suggested that this effect may only have a role in a state of poor health,[18], This inhibition appears to be mutual, with higher concentrations of glucocorticoids inhibiting the interconversion of oxygenated DHEA metabolites,[42] and when assessing 7-hydroxyDHEA and the isomer, they do not appear to directly interfere with the cortisol receptor or its activation, similar to parent DHEA. Green tea alone can increase weight loss of 3lbs over 12 weeks even when theres not been a change in diet or physical activity. I.e those who are likely to be participating in competitive sports.
