Research now shows that melatonin may increase metabolism and improve our ability to lose weight. Melatonin fights fat in two major ways: it has the ability to assist in turning fat into energy rather than storing it and it improves thermogenic capacity of the mitochondria.
To quote the study, “In conclusion, we demonstrated that small doses of melatonin (1 and 3 mg/d) have beneficial effects on body composition in terms of reduced fat mass and borderline significantly increased lean mass in postmenopausal women.” (Clinical Endocrinology, September 2015) 5 mg/daily of melatonin has also ...
Stomach upset. You may feel stomach discomfort when you take melatonin. Melatonin can cause symptoms like nausea or stomach cramps. If your stomach discomfort worsens while taking melatonin, contact your healthcare provider.
Does melatonin cause weight gain? The short answer is no. In fact, melatonin may well do the opposite. Melatonin is an incredibly important hormone that all human bodies produce so that we can sleep.
The current clinical consensus is that daily melatonin consumption is considered safe. However, according to a 2020 article published in Antioxidants, more research is needed to determine the correct dose and time and understand potential long-term effects.
In the gut it seems that melatonin plays significant roles in regulating intestinal motility, the immune system, GI secretion, and the release of peptides involved in energy balance such as peptide YY[55].

Scientists found that taking a melatonin supplement over time increases the calorie-burning effects of exercise and exposure to cold, which can help people lose weight. This is due in part to the fact that melatonin supplements trigger the production of “good” fat that burns calories.
The results of many experimental studies and clinical trials suggest that in the case of obesity, the circadian and seasonal rhythm of melatonin secretion is disturbed [18, 19]. Lower levels of melatonin secretion in the autumn-winter period can increase appetite and lead to weight gain [20].
Melatonin has been shown to possess anti-inflammatory effects, among a number of actions. Melatonin reduces tissue destruction during inflammatory reactions by a number of means. Thus melatonin, by virtue of its ability to directly scavenge toxic free radicals, reduces macromolecular damage in all organs.
Less common melatonin side effects might include short-lasting feelings of depression, mild tremor, mild anxiety, abdominal cramps, irritability, reduced alertness, confusion or disorientation. Because melatonin can cause daytime drowsiness, don't drive or use machinery within five hours of taking the supplement.
Our results indicate that pharmacological doses of melatonin delay gastric emptying via mechanisms that involve CCK2 and 5-HT3 receptors. Moreover, it appears that exogenous melatonin inhibits gastric motility in part by activating sympathetic neurons.
Regardless of whether it truly helps with sleep or not, Dr. Ramkissoon doesn't recommend taking melatonin long-term. "Namely, because if you think you need to take melatonin every night to get to sleep, we need to understand why that's the case," explains Dr. Ramkissoon.
If you've been drinking alcohol, it's also not safe to take melatonin. Melatonin is also not for you if you're pregnant or breastfeeding. Researchers simply don't have enough data to know if it's safe for fetuses or breastfed babies.
Taking melatonin tablets adds to your body's natural supply of the hormone. This can help you get to sleep and improve the quality of your sleep. How long will it take to work? Melatonin takes around 1 to 2 hours to work.
Our finding that melatonin is positively associated with increased bloating and GI pain contrasts with studies showing that melatonin treatment reduces pain (38,39) and administration of melatonin in postmenopausal women with IBS-C reduces bloating (55).
1. Crunches: The most effective exercise to burn stomach fat is crunches. Crunches rank top when we talk of fat-burning exercises.
In addition to its rather well-established roles in the regulation of circadian rhythms, sleep, and reproduction, melatonin has also been identified as an important regulator of glucose metabolism.
Melatonin increased the thyroid gland size relative to body weight and increased the total T4 content and T4:T3 ratio in the thyroid gland. There was no effect of melatonin on TSH response to TRH or hypothalamic TRH content. Optic nerve section increases serum TSH and T3 levels.
Recently, it has been reported that melatonin can modulate specific gut microbiota activity and abundances [9]. It has been shown that melatonin can influence the swarming and motility of human intestinal bacteria, especially Enterobacter aerogenes [9].
