Do Fat Burners Affect Women’s Period?

If you're a woman looking to shed some pounds you might consider giving burners a try. These supplements claim to enhance your metabolism, curb your cravings and boost your energy levels for increased burning. Do they actually deliver on these promises? Perhaps more importantly, do they have any impact on your menstrual cycle?

What Are Fat Burners?

Fat burners are products that contain various ingredients that are supposed to help you burn more fat. Some of the common ingredients are caffeine, green tea extract, capsaicin, garcinia cambogia, and raspberry ketones. 

How Do Fat Burners Affect Your Period?

The occurrence of your cycle is influenced by a complex interplay between your ovaries and brain. Changes in hormone levels trigger ovulation while further hormonal changes lead to menstruation. Any disruptions in this interaction can prevent ovulation resulting in the skipping of a period.

Hormone levels are influenced by factors such as weight and body percentage. If you are underweight or overweight it is more likely for your periods to become irregular or even absent altogether.

The impact of burners on your menstrual cycle can vary depending on their ingredients and dosage. Different effects may be observed as a result.


Caffeine has the potential to impact your cycle by influencing stress hormones like cortisol and adrenaline. These hormones can potentially disrupt the process of ovulation and your overall menstrual cycle. Additionally caffeine may interfere with the absorption of iron which is crucial, for maintaining healthy blood flow during your period.

Green tea extract

Green tea extract has the potential to impact your cycle in different ways depending on the dosage. It contains phytoestrogens, which are plant compounds that imitate the effects of estrogen as well as anti estrogens that hinder estrogens activity. Phytoestrogens can assist in maintaining hormone balance and regulating your cycle. On the other hand anti estrogens can lower estrogen levels and potentially lead to irregular or missed periods.


Capsaicin has the potential to impact your cycle by enhancing blood circulation in your pelvic region potentially resulting in longer or heavier periods. Additionally capsaicin may stimulate contractions within the uterus leading to cramps or symptoms associated with syndrome (PMS).

Garcinia cambogia

Garcinia cambogia may impact your cycle by reducing the levels of progesterone, a hormone responsible for preparing your uterus for pregnancy. Decreased progesterone levels can lead to spotting, missed periods or challenges, in conceiving a baby. A safe dose of this ingredient must be maintained to avoid the said effects. Fat burners like SHRED with MCT Fat Burner have a safe dosage for women in avoiding the likelihood of experiencing side-effects.

Raspberry ketones

Raspberry ketones might affect your cycle by increasing estrogen. Estrogen controls uterine lining growth. High estrogen levels can cause period lengthening, breast pain, bloating, and mood swings. Luckily, Shred Fat Burner is formulated to avoid such side-effects.

Fat burners are supplements that can aid in weight loss by boosting your metabolism, curbing your appetite and increasing your energy levels. However they may also have an impact on your cycle depending on their ingredients and dosage. Some of these effects can be advantageous, for both weight loss and overall health while others may be detrimental or counterproductive.

Therefore it is important to consult with your doctor. Carefully read the product label before using any fat burner. Additionally it is recommended to maintain a diet and exercise routine to achieve optimal results. It's essential to remember that fat burners are not pills that guarantee instant slimming. They should be viewed as tools that can assist you on your weight loss journey.
