What is 7-Keto DHEA?

7-Keto DHEA is a metabolite of DHEA — the hormone your body naturally makes from cholesterol. Unlike regular DHEA, 7-Keto doesn't convert into estrogen or testosterone, which makes it a popular option for people who want some of DHEA's metabolic benefits without affecting sex hormone levels. It's found naturally in small amounts in the body, but levels drop significantly as we age.

How does 7-Keto DHEA work?

7-Keto helps rev up your metabolism by activating enzymes in the liver that speed up how your body burns calories — a process called thermogenesis. It also appears to support immune function by promoting the activity of certain immune cells. Because it doesn't convert to estrogen or testosterone, it avoids many of the hormonal concerns associated with standard DHEA supplementation.

What forms does 7-Keto DHEA come in?

Most commonly found as oral capsules, typically in 25 mg, 50 mg, or 100 mg doses. Topical creams also exist and may support absorption through the skin, though oral forms are the most studied.

Where it comes from:

7-Keto DHEA was identified as a distinct DHEA metabolite in the 1950s but gained commercial attention after researchers in the 1990s found it could support metabolism without the hormonal side effects of DHEA. It was patented and developed specifically as a supplement targeting age-related metabolic decline.

What does 7-Keto DHEA help with?

• Weight management and stubborn fat: 7-Keto helps the body burn calories more efficiently by activating thermogenic enzymes in the liver. Clinical trials combining 7-Keto with calorie restriction and exercise have shown it can produce significantly more fat loss than diet and exercise alone.
• Slow metabolism (age-related): As 7-Keto levels naturally drop with age, metabolism tends to slow down. Supplementing can help counteract this by supporting your resting metabolic rate — how many calories your body burns even at rest.
• Immune system support: 7-Keto has been shown to enhance the activity of natural killer cells and other immune cells that help defend the body against infections and abnormal cells. This effect appears particularly relevant for older adults whose immune function has declined.
• Thyroid function support: Some evidence suggests 7-Keto may support the conversion of inactive thyroid hormone (T4) into active thyroid hormone (T3), which plays a key role in metabolism and energy. This is one reason it's often recommended for people with sluggish thyroid function.
• Cognitive decline (age-related): Early research suggests 7-Keto may support memory and mental sharpness in older adults, possibly by influencing certain brain chemicals. The evidence here is still limited but promising.
• Adrenal fatigue and low DHEA levels: People with low DHEA levels — common with chronic stress or aging — sometimes benefit from 7-Keto as a gentler alternative to DHEA supplementation that doesn't carry hormonal risks.
• Athletic performance and body composition: Some athletes use 7-Keto to support lean muscle mass and reduce body fat percentage, particularly during calorie restriction. Its thermogenic properties may help preserve metabolic rate during cutting phases.
• Stress and cortisol balance: There is some preliminary evidence suggesting 7-Keto may help modulate cortisol activity, which could be beneficial for people dealing with chronic stress, though this area needs more robust clinical research.

What can 7-Keto DHEA help prevent?

• Age-related metabolic slowdown (resting metabolic rate decline)

Which foods are rich in 7-Keto DHEA?

7-Keto DHEA is not found in any food — it's a specific metabolite produced inside the body. However, you can support your body's broader adrenal and metabolic health through foods that supply the raw materials. These include: (1) Eggs and fatty fish — rich in cholesterol and healthy fats, which are the building blocks for DHEA and its metabolites. (2) Cruciferous vegetables like broccoli and cauliflower — support healthy hormone metabolism. (3) Wild salmon and sardines — omega-3s help reduce inflammation that can suppress adrenal output. (4) Avocados — healthy fats support adrenal function and overall hormonal balance. (5) Foods to avoid: excess sugar and refined carbs, which raise cortisol and suppress DHEA production naturally.

What are the side effects of 7-Keto DHEA?

• Mild acne or oily skin (rare, especially at higher doses)
• Occasional digestive upset or nausea
• Headache (uncommon)
• Mild palpitations at higher doses in sensitive individuals
• Not recommended during pregnancy or breastfeeding due to insufficient safety data

Good to know:

7-Keto DHEA is considered safe and well-tolerated in clinical trials at standard doses. Because it doesn't convert to estrogen or testosterone, it avoids many of the hormonal side effects associated with regular DHEA.

How much 7-Keto DHEA should you take?

• Recommended daily: 100–200 mg per day, typically split into two doses
• Best time of day: Morning and early afternoon doses are preferred; avoid taking late in the day as it may mildly stimulate energy
• With or without food: Best taken with a meal containing some fat to support absorption
• Time to effect: 4–8 weeks for measurable changes in body composition or metabolism
• How long to take it: Often used in 8–12 week cycles with breaks in between, though some adults use it continuously at lower doses. Consult a healthcare provider for longer-term use.
