Adiponectin
What Does Adiponectin Measure?
Adiponectin is a protein hormone produced and secreted exclusively by fat (adipose) tissue. A blood test for adiponectin measures the concentration of this hormone circulating in your bloodstream, typically expressed in micrograms per milliliter (µg/mL). Unlike most hormones produced by fat cells, adiponectin levels are paradoxically lower in people with more body fat and higher in leaner individuals, making it a unique and informative marker of metabolic health.
Why Does Adiponectin Matter?
Adiponectin plays a critical role in regulating glucose metabolism and fatty acid oxidation, and it has powerful anti-inflammatory and insulin-sensitizing effects throughout the body. Low adiponectin levels are strongly associated with insulin resistance, type 2 diabetes, metabolic syndrome, cardiovascular disease, and certain cancers. High adiponectin levels, on the other hand, are generally protective—linked to reduced inflammation, better insulin sensitivity, and a lower risk of heart disease. Because it reflects the functional health of adipose tissue rather than simply how much fat is present, adiponectin is considered one of the most clinically meaningful markers of cardiometabolic risk available through a standard blood test.
Normal Ranges
Males
3–14 µg/mL (adult males typically have lower levels than females)
Females
5–20 µg/mL (adult females generally have higher levels)
Children
Varies by age and puberty stage; generally 8–20 µg/mL in prepubertal children, declining during puberty
Causes of High Levels
- Low body fat percentage or lean body composition
- Caloric restriction and fasting states
- Regular aerobic exercise and physical activity
- Use of thiazolidinedione (TZD) medications such as pioglitazone
- Anorexia nervosa or severe malnutrition
- Chronic kidney disease (reduced renal clearance of the hormone)
Causes of Low Levels
- Obesity, particularly central (abdominal) obesity
- Type 2 diabetes and insulin resistance
- Metabolic syndrome
- Polycystic ovary syndrome (PCOS)
How to Improve Your Adiponectin
Diet
- Follow a Mediterranean-style diet rich in olive oil, fish, nuts, and vegetables, which is associated with higher adiponectin levels
- Increase intake of omega-3 fatty acids from fatty fish (salmon, mackerel, sardines) at least 2–3 times per week
- Consume high-fiber foods such as legumes, whole grains, fruits, and vegetables to improve insulin sensitivity
- Include magnesium-rich foods like spinach, pumpkin seeds, almonds, and dark chocolate, as magnesium intake correlates with adiponectin levels
- Reduce intake of refined carbohydrates, added sugars, and trans fats, which suppress adiponectin production
Supplements
- Fish oil (omega-3 fatty acids): 2–4 g per day of combined EPA and DHA has been shown to raise adiponectin levels
- Magnesium glycinate or citrate: 200–400 mg per day may improve adiponectin levels, especially in those with deficiency
- Berberine: 500 mg two to three times daily has demonstrated ability to increase adiponectin while improving insulin sensitivity
- Curcumin (turmeric extract): 500–1,000 mg per day with piperine may raise adiponectin and reduce inflammation

Frequently Asked Questions
What does it mean if my adiponectin is low?
Low adiponectin levels generally indicate that your adipose (fat) tissue is not functioning optimally, often because there is too much of it—particularly visceral fat around the organs. Low levels are strongly linked to insulin resistance, increased inflammation, a higher risk of type 2 diabetes, and cardiovascular disease. If your adiponectin is low, it is a signal worth discussing with your doctor alongside other metabolic markers like fasting insulin, HbA1c, and triglycerides to get a fuller picture of your cardiometabolic health.
Why do women have higher adiponectin levels than men?
Women naturally have higher circulating adiponectin levels than men, and the exact reasons are not fully understood. Estrogen is thought to stimulate adiponectin production, while testosterone may suppress it, which partly explains the sex difference. Additionally, women tend to store more subcutaneous fat (under the skin) compared to visceral fat, and subcutaneous fat produces more adiponectin than the metabolically harmful visceral fat that is more common in men. This difference is one reason premenopausal women have lower cardiovascular disease risk compared to men of the same age.
Can you have adiponectin levels that are too high?
While high adiponectin is generally considered beneficial and protective against metabolic disease, extremely elevated levels can sometimes occur in pathological conditions. In chronic kidney disease, reduced clearance of adiponectin causes levels to rise significantly, which in this context is associated with poor outcomes rather than protection. Very high levels can also be seen in severe malnutrition or eating disorders like anorexia nervosa. In otherwise healthy people, high adiponectin from lifestyle factors like regular exercise and a healthy diet is not a concern.
