Apart from caffeine stimulation, there is no warning of any side effects that the Leptiburn supplement may have, according to the manufacturer. However, the product contains irvingia gabonesis, panax notoginseng, green tea and yerba mate extracts, which may cause side effects in certain individuals.
Irvingia gabonensis is used to treat diabetes, high cholesterol and obesity but can cause side effects like flatulence, headaches and sleep problems, explains WebMD. In people with diabetes, the herb can lower blood sugar levels too much, so it is best to monitor blood sugar levels regularly while taking it.
Panax notoginseng is used to treat various blood disorders, but several side effects, such as allergic shock, have been reported, notes Dr. Subhuti Dharmananda. These reactions usually go away on their own, unless a person experiences anaphylactic shock and has dangerously low blood pressure.
Green tea extract is safe to use in the short term, but people may experience stomach upset and constipation from taking it, according to RxList. Side effects from the caffeine in the herb include headache, sleep problems and confusion. Green tea also reduces iron absorption from food.
Yerba mate extract can increase the risk of certain cancers if it is taken long-term in large amounts, explains Memorial Sloan Kettering Cancer Center. People who smoke or drink too much alcohol have an additional risk of cancer when they supplement their diets with yerba mate.
