When it comes to DHEA and DHEA supplements, you may immediately think of bodybuilders. That’s because DHEA (technically, dehydroepiandrosterone) is considered a “pro-hormone” tied to longevity, lean muscle mass and a strong body.
But DHEA’s uses go far beyond improving someone’s body composition — it also helps improve bone density, promotes heart health, controls cholesterol levels, fights fatigue and improves production of important sex hormones like testosterone and estrogen.
What Is DHEA?
The truth is we all (men and women) naturally create DHEA in our bodies — the hormone plays a role in more than 150 different metabolic functions. In fact, it’s one of the most abundant hormones in the human body! The adrenal glands are the primary producers of naturally occurring DHEA, but men also secrete it from their testes. Once produced, your body converts it to several other hormones, including androstenedione and several sex hormones, earning it the nick name “the parent hormone.”
In some ways, DHEA works like a natural anabolic steroid, since it boosts production of natural growth hormones that help build lean muscle mass and fight fat accumulation. That’s why the supplement form is popular among athletes and bodybuilders. In fact, although they’re normally very safe, the National Collegiate Athletic Association (NCAA) banned DHEA supplements because their benefits can be very strong.
DHEA levels naturally start to decline after the age of 30, which is precisely when many adults start to experience weight gain, sluggishness, lowered libido and other symptoms caused by higher levels of inflammation.
Considered to be one of the most rapidly-decreasing hormones in the human body, it pays to hold onto all the DHEA that you can. Every decade of life after the age of 30, DHEA loss accelerates. By the time someone reaches the age of about 75, they produce only about 10 to 20 percent of the original DHEA they created in their youth.
1. Lowers Inflammation
Inflammation is the root of most diseases and is tied to just about every age-related health problem that exists. Restoring DHEA production, both naturally with certain lifestyle habits and also through use of supplements, can improve many youthful qualities. DHEA’s ability to lower inflammation and balance hormones helps facilitate higher energy levels, a leaner body and more vitality. DHEA taken in supplement form boosts certain hormone levels (like testosterone and estrogen), helps prevent autoimmune reactions and mood disorders like depression and improves overall quality of life in many ways.
Research shows that people with metabolic syndrome — a term characterised by a combination of risk factors related to high inflammation such as obesity/being overweight, having high cholesterol, high blood pressure and diabetes — tend to have lower levels of DHEA. Studies also show that obese adults tend to produce less DHEA compared to healthy weight adults. Scientists also associate low DHEA with inflammatory autoimmune disorders like lupus and arthritis.
Studies involving women with autoimmune disorders like lupus and thyroid disorders suggest that low DHEA levels negatively impact internal organs, the skin and the immune system. Research also suggests that DHEA supplementation may help improve symptoms of aches and pain, ongoing fatigue and inflammatory skin reactions safely without many, or any, side effects in many adults.
2. Helps Improve Bone Density and Muscle Mass
DHEA is associated with anti-aging effects that help protect bone loss and lower the risk for fractures or conditions like osteoporosis. Apart from ageing, bone loss occurs at higher rates in people with thyroid or autoimmune disorders, poor diets, sedentary lifestyles, eating disorders and hormonal imbalances.
Some evidence suggests that higher DHEA levels improve estrogen production, resulting in higher bone mineral density in older or post-menopausal women. These women are most at risk for bone-related disorders.
Since sports organisations like the NCAA added DHEA supplements to their banned list, there’s been a lot of backlash. DHEA is not a synthetic steroid or performance enhancer that promotes abnormal muscle growth. It actually works more like a repair signal that helps the body recover from intense training and physical activity. It helps cells take up glucose for energy, supports many different functions of the metabolism and prevents fat accumulation, especially dangerous visceral fat.
3. Protects Against Depression, Cognitive Decline and Mood Swings
According to some studies, higher levels of DHEA may lower rates of major depression and improve overall emotional stability. Research suggests that supplementing with 200 milligrams of DHEA (depending on the individual case) can help lower depression and mood-related symptoms, including loss of pleasure (called anhedonia), loss of energy, lack of motivation, emotional “numbness,” sadness, irritability, inability to cope with stress and excessive worrying.
DHEA helps balance production of other hormones needed to maintain a positive outlook, energy and motivation, such as testosterone and estrogen. It also lowers the risk for many health conditions and symptoms, some of which contribute to depression. These include weight gain, sexual dysfunction, infertility and adrenal insufficiency (a serious condition in which the adrenal glands do not make enough hormones).
According to the National Institute of Health, DHEA can be used to slow or reverse cognitive decline as a result of ageing, including improving thinking skills in older people and slowing the progression of Alzheimer’s disease. However, high doses are often needed to achieve these results, which can be risky. Several studies found that taking 100 milligrams of DHEA daily for four weeks might also help improve vision and memory loss in middle-aged and older adults.
4. Aids in Weight Loss and Building Muscle Mass
DHEA supplements are often used to help promote weight loss and to support athletic training with a focus on building lean muscle mass. 7-Keto, one type of DHEA supplement, helps adults maintain strong metabolism levels while aiding in the prevention of age-associated fat gain and muscle loss. It’s certainly not a magic bullet for weight loss, but it can be helpful for some people.
While calorie intake and energy expenditure are important factors involved in managing your weight, hormones play a crucial role, too. DHEA helps improve the body’s natural ability to use energy and burn fat, two metabolic processes that usually decline as someone ages. DHEA helps shuttle glucose to cells for energy, reduce insulin levels and stimulate fat burning. As I mentioned earlier, DHEA improves lean muscle mass. This helps you more efficiently burn calories, even while resting.
5. Improves Heart Health and Lowers Diabetes Risk
Acquiring more DHEA is linked to a lower risk of clogged arteries, blood clots, high cholesterol, heart disease and insulin resistance/diabetes in adults, although researchers still aren’t exactly sure why. DHEA may improve blood vessel function and reduce the risk for heart disease and diabetes by lowering inflammation, supporting a healthy metabolism, improving use of glucose and insulin and improving production of sex hormones.
Results of studies suggest that DHEA protects against the increase in dangerous visceral fat and the development of insulin resistance induced by a poor diet and lifestyle. Other research shows DHEA plays a protective role in the development of atherosclerosis (hardening of the arteries) and coronary heart disease by interfering with atherogenic processes and enzymes such as glucoso-6-phosphate dehydrogenase.
6. Decreases Sexual Dysfunction and Can Improve Libido
Although it’s not fool-proof or without risk for side effects, DHEA has helped many people overcome sexual dysfunctions, loss of libido, erectile dysfunction, hormonal imbalances and menopause symptoms like vaginal dryness. Study results over the years have been mixed, but some research demonstrates that lower levels of DHEA occur in men with erectile dysfunction. DHEA supplementation can benefit both men and women with various symptoms related to declining sex hormones, according to some studies.
Low testosterone and hormone deficiency in men (also sometimes called partial androgen deficiency) contribute to problems like aches, pains, weight gain, loss of functioning and sexual problems, but some research suggests that taking 200 milligrams of DHEA daily for one year might improve these symptoms.
Other evidence shows that taking DHEA for six months helps lower sexual symptoms related to nerve damage and diabetes, such as impotence. Women taking 100 milligrams of DHEA daily could see a decrease in certain menopausal symptoms like hot flashes, vaginal dryness and weight gain.
