Leptin isn't a vitamin or mineral. You can't absorb it from a pill. In fact, “leptin supplements” don't contain any actual leptin. If they did, your stomach would simply digest them before they could have any effect on your body.
In our study, vitamin A concentrations were associated with high concentrations of leptin in the overall population, and the same was observed in women that had low BMI, low body fat percent and low waist circumference.
Increasing physical activity, getting enough sleep, decreasing sugar intake and including more fish in your diet are some steps you can take to improve leptin sensitivity. Lowering your blood triglycerides is important, too.
Plasma leptin levels decrease during fasting[8] or energy restriction[9] and increase during refeeding,[10] overfeeding,[11] and surgical stress. [12,13] Insulin, glucocorticoids, serotonin, and estrogen have been reported to stimulate leptin secretion.
This study showed that vitamin D administration is associated with an increase in adiponectin and a decrease in leptin level in ESRD patients.
Zinc might play an important role in appetite regulation and its administration stimulates leptin production.
In terms of weight loss, more leptin is not necessarily what matters. How well your brain interprets its signal is much more significant. Therefore, taking a supplement that increases blood leptin levels does not necessarily lead to weight loss.

Leptin is a hormone produced naturally in the body that helps regulate feelings of satiety (fullness or hunger). Because of this, marketers commonly promote leptin supplements as a weight-loss aid. But these supplements don't actually contain leptin, which means they're unlikely to lead to weight loss.
Leptin receptor deficiency is caused by mutations in the LEPR gene. This gene provides instructions for making a protein called the leptin receptor, which is involved in the regulation of body weight.
Discovered in 1994, leptin is an adipokine, a protein that functions as a hormone (1). Two major producers and secretors of leptin are the adipose tissue and the gastric mucosa (1–4). Leptin promotes satiety and has a central role in energy balance and weight management.
Leptin is made by the adipose tissue (fat-storing cells) in your body. Its main role is to regulate fat storage and how many calories you eat and burn. Leptin released from adipose cells travels to the brain via the bloodstream. It acts on the hypothalamus in the brain, which regulates hormones in your body1.
In non-obese subjects, omega-3 is observed to decrease circulating levels of leptin; however, omega-3-associated increases in leptin levels have been observed in obese subjects. This may pose benefits in the prevention of weight regain in these subjects following calorie restriction.
Leptin. What it is: Leptin is derived from the Greek word for “thin,” because rising levels of this hormone signal the body to shed body fat. Leptin also helps regulate blood sugar, blood pressure, fertility and more.
Leptin is a peptide hormone that is produced by fat cells that plays a role in body weight regulation. It does this by acting on the hypothalamus (a region in the brain that controls homeostasis) to suppress appetite and burn fat stored in adipose tissue (body fat).
Probiotics can decrease circulating leptin levels by alteration of the gut microbiota. Thus, they may have anti-obesogenic effects.
[36] It was established that zinc deficiency significantly inhibited leptin secretion from the fatty tissue and IL-2 and TNF-α levels decreased parallel to inhibited leptin levels.
Eliman and Marcus, in an experimental fasting study (fasting for 48 hours), reported a rise in leptin levels after the evening fast-breaking meal [34]. This result is in contrast to that of the present study, which showed a significant reduction in leptin at 22:00.
Fish oil has been shown to reduce leptin levels (11) directly (mechanism not completely understood) probably through its effects on inflammation and on insulin. Bottom line: Fish oil helps lower leptin resistance and can help increase metabolism and reduce appetite through this mechanism.
Among the most recent studies that found that fish oil had a positive effect on weight or fat loss, daily dosages of 300–3,000 mg were used ( 27 , 28 ). According to the US Food and Drug Administration (FDA), intake of fish oil omega-3s is considered safe if the daily dose does not exceed 3,000 mg per day (29).
A high omega-6 fatty acid intake and a high omega-6/omega-3 ratio are associated with weight gain in both animal and human studies, whereas a high omega-3 fatty acid intake decreases the risk for weight gain.
