Looking for a proven metabolism booster that will not leave you jittery or disrupt your hormone levels? NOW 7-KETO 25mg delivers a patented, naturally occurring metabolite of DHEA (dehydroepiandrosterone). It is clinically demonstrated to support thermogenesis (cellular heat and calorie burning) and resting metabolic rate without converting into estrogen or testosterone.
Medical & Nutritional Evidence Summary:
Unlike standard DHEA, 7-Oxo-DHEA does not alter circulating sex hormones. In peer-reviewed, double-blind trials, participants pairing 7-Keto with moderate diet and exercise burned up to 3 times more body fat than diet and exercise alone while protecting against metabolic slowdown.
✓100% Non-Hormonal: Zero conversion to estrogen or testosterone
✓Thermogenic Action: Activates liver enzymes that convert fat into heat
✓Stimulant-Free: Does not cause heart racing, insomnia, or jitters
✓Flexible Dosing: 25 mg micro-capsules allow personalized, split daily use
What is 7-KETO 25mg? (In Plain English)
To understand 7-KETO DHEA, think of your adrenal glands as a factory that naturally produces DHEA—one of the body's most abundant master hormones. As you enter your late 20s and 30s, your body's natural production of DHEA and its down-stream compounds begins a steady decline. By age 50, blood levels are often down by more than 50%. This decline frequently coincides with age-related weight gain, slower recovery, and stubborn midsection fat.
When the body breaks down DHEA, it splits it into several byproducts. One path turns into sex hormones (androgens and estrogens). The other path creates 7-Oxo-dehydroepiandrosterone, commonly known by its patented trademark name: 7-Keto®.

How 7-KETO Works: Turning Up Your Cellular Furnace
When you cut calories to lose weight, your body senses a food shortage and enters survival mode. It compensates by dropping your Resting Metabolic Rate (RMR)—burning fewer calories every minute you sit, sleep, and breathe. This evolutionary defense mechanism is why most weight-loss efforts hit an abrupt plateau.
7-KETO 25mg works around this defense mechanism through two distinct, scientifically mapped cellular biological pathways:
1. Activating Thermogenic Enzymes
Research spearheaded by Henry Lardy, Ph.D., demonstrated that 7-Oxo-DHEA significantly stimulates three critical fat-burning enzymes in the liver:
Mitochondrial Glycerol-3-Phosphate Dehydrogenase: Diverts fats directly toward cellular energy generation.
Cytosolic Malic Enzyme: Accelerates the breakdown of fatty acids.
Fatty Acyl-CoA Oxidase: Drives fatty acids into the mitochondria to be burned as body heat rather than stored in adipocytes (fat cells).
2. Preserving Active Thyroid (T3) Hormone
During dieting, your thyroid frequently down-regulates its active hormone (Triiodothyronine, or T3), slowing total calorie burn. Human trials indicate that 7-Keto supplementation helps support healthy circulating T3 levels without raising Thyroid-Stimulating Hormone (TSH) or interfering with the thyroid gland's negative feedback loop. This keeps your daily metabolic engine running at baseline during calorie reduction.
Unlike many herbal "fat burners" supported only by test-tube experiments, the active 7-Keto compound in this formula has undergone rigorous, double-blind, placebo-controlled human clinical trials.
Study 1: 300% Greater Fat Loss in an 8-Week Double-Blind Trial
In a landmark randomized, double-blind, placebo-controlled clinical study, researchers evaluated 30 healthy, overweight adults who exercised 3 days per week for 45 minutes and followed an 1,800-calorie diet. Half received 100 mg of 7-Keto twice daily, while the other half received an inert placebo.
Clinical Outcome: The 7-Keto group lost an average of 6.34 lbs (2.88 kg) and reduced body fat by 1.8%, compared to just 2.13 lbs (0.97 kg) and 0.57% body fat in the placebo group (P < 0.05). Thyroid T3 levels rose significantly without any change in TSH, heart rate, or blood pressure.

Study 2: Preventing Diet-Induced Metabolic Crash (RMR Preservation)
A clinical study measured the resting metabolic rate of calorie-restricted adults over 7 days of supplementation with 7-Keto versus placebo. While the placebo group experienced the anticipated drop in resting metabolism from calorie restriction, the group taking 7-Keto experienced an elevated metabolic rate.
Clinical Outcome: 7-Keto increased Resting Metabolic Rate (RMR) by +1.4% above baseline, counteracting the expected –3.9% metabolic decline observed during dietary caloric reduction.

Study 3: Safety, Tolerability, and Lack of Hormonal Conversion
A clinical safety and pharmacokinetic trial analyzed volunteers receiving oral doses up to 200 mg daily for 28 days to determine whether 7-Keto had any impact on circulating sex hormones or vital organs.
Clinical Outcome: Total and free testosterone, estradiol, estrone, progesterone, and sex-hormone-binding globulin (SHBG) remained unchanged. Liver enzymes, kidney filtration, and blood glucose remained within normal, healthy parameters throughout the study.

Pro-Tip for Maximum Absorption: Because 7-Oxo-DHEA is fat-soluble, always take your capsules with a small amount of dietary fat (such as avocado, whole eggs, nuts, or fish oil) to optimize intestinal uptake. Avoid taking late in the evening if you are exceptionally sensitive to metabolic energy shifts.
Safety Profile, Drug Interactions & Athlete Advisory
Because 7-Keto does not convert into active estrogens or androgens, it does not carry the typical risks linked to steroid precursor supplementation (such as gynecomastia, hirsutism, prostate enlargement, or female voice deepening). However, professional responsibility requires transparent medical guidance:
Thyroid Medication Considerations
7-Keto may upregulate T3 hormone activity. If you currently take prescription thyroid hormone replacements (such as levothyroxine, Synthroid, or Armour Thyroid), consult your endocrinologist before starting, as dose adjustments may be warranted.
Competitive Athletes: WADA Prohibited List
The World Anti-Doping Agency (WADA), NCAA, and various military bodies categorize 7-Keto DHEA under Section S1. Anabolic Agents due to its steroidal backbone structure. If you are subject to drug testing, do not take this product.

Frequently Asked Questions (FAQ)
Direct, doctor-reviewed answers to the most common customer questions about 7-KETO 25mg.
Will NOW 7-KETO 25mg show up on a drug test?
For standard civilian workplace drug screenings (5-panel or 10-panel SAMHSA tests looking for opiates, amphetamines, THC, cocaine, etc.), 7-Keto will not trigger a false positive. However, for competitive athletes subject to World Anti-Doping Agency (WADA) or collegiate NCAA testing, 7-Keto is on the banned list of anabolic agents and will cause a failed sports test.
Can women safely take 7-KETO 25mg without growing facial hair or breaking out?
Yes. Unlike ordinary DHEA, which frequently metabolizes into testosterone and dihydrotestosterone (DHT) causing hormonal breakouts and coarse hair growth in women, 7-Keto is biochemically unable to convert back into active androgens. It safely supports thermogenesis without masculinizing side effects.
Why should I choose 25mg capsules over 100mg capsules?
The 25mg capsule offers optimal dosing flexibility. Those who are lighter in body weight, new to thermogenic supplements, or sensitive to metabolic changes can begin conservatively with a single 25mg or 50mg dose. You can step up your dose gradually to 75mg or 100mg as needed, which is impossible with fixed 100mg tablets.
Does 7-KETO contain caffeine or cause jitters?
No. NOW 7-KETO 25mg is 100% stimulant-free. It does not contain caffeine, synephrine, ephedra, or yohimbine. It elevates calorie expenditure by stimulating liver and mitochondrial enzymes, not by overstimulating your central nervous system or elevating your resting heart rate.
How long does it take to see results with 7-KETO?
In double-blind human clinical trials, measurable differences in body composition, fat loss, and resting metabolic rate were documented between weeks 4 and 8 of continuous supplementation alongside regular exercise and calorie control. Consistent daily intake is essential to maintain elevated thermogenic enzyme activity.
Can I take 7-KETO alongside other weight management supplements?
Yes. Because 7-KETO works via liver mitochondrial enzymes rather than the central nervous system, it can be stacked with fat-transport nutrients like L-Carnitine, fiber supplements (like glucomannan), or green tea extract without overstimulating the nervous system.
