The benefits of these tiny berries are numerous when you consume them in moderation, but with excess intake, there are also several side effects of goji berries. They may interact with certain drugs or cause an allergic reaction in some individuals (1). In this article, we have discussed the possible side effects of goji berries. Keep reading to know more!
What Are The Side Effects Of Goji Berries?
1. May Cause Drug Interactions
Goji berries can interact with certain drugs, including warfarin. In a study, a 71-year-old woman took goji berry juice while she was on warfarin therapy. The woman experienced symptoms of bruising, rectal bleeding, and bleeding from the nose (2). Her symptoms improved once she stopped taking the juice. Goji berry juice is a popular herbal drink that can increase bleeding. It interacts with and enhances the action of drugs like warfarin, which is an anticoagulant (3).
2. May Lower Blood Sugar Way Too Much
Goji berries can lower blood sugar levels. They have been identified as possible treatment options to manage diabetes (4). But if you are already on diabetes medication, they may cause your blood sugar levels to decrease way too much. There is no direct research stating that goji berries can cause hypoglycemia. However, it is better to exercise caution. Please check with your doctor before consuming goji berries if you are undergoing diabetes treatment.
3. May Cause Allergies
Goji berries can cause anaphylaxis, a condition in which the body becomes hypersensitive (5). The lipid transfer proteins in the berries could be responsible for these reactions. The symptoms of anaphylaxis include hives, airway obstruction, gastrointestinal issues, and shock (6). Individuals at risk of food allergies must not consume goji berries until they get approval from their doctor.
4. May Cause Hypotension
Studies show that goji berries can help lower blood pressure levels (7). This may be good news, but it can cause problems if the individual is already on medications for treating high blood pressure. Goji berries may enhance the action of medications that lower blood pressure. This can lead to hypotension or blood pressure levels plummeting to dangerously low levels. Though there is no direct research to establish this, there is a possibility. If you are already on medication to treat hypertension, please check with your doctor before you consume goji berries.
5. May Lead To Diarrhea
In one case report, an individual who had consumed goji berries (goji berry tea) had experienced non-bloody diarrhea and abdominal pain. The berries were found to modulate certain genes in the human body. Another possible reason for these side effects could be contamination (8). Hence, if you have digestive issues, please check with your doctor before consuming goji berries.
6. May Cause Miscarriage
Goji berries contain betaine (9). Betaine could also be used to induce menstruation and abortion. The berries also have an estrogen-mimicking effect. Hence, they must not be used by pregnant or lactating women or anyone with diseases sensitive to estrogen (10).
Are goji berries carcinogenic? Check out the infographic given below to learn about the side effects of Goji berries. Eva De Angelis, a dietitian nutritionist, says, “Goji berries have always been commonly used in traditional Chinese herbal medicine. They’ve also been labeled a superfood because of their high concentrations of bioactive compounds like polysaccharides, polyphenols, flavonoids, and carotenoids. Most of these compounds have the potential to be powerful allies in the fight against cancer.” Do goji berries have heavy metals? According to Eva De Angelis, a dietitian nutritionist, “Like any other crop, goji berry plants are treated with pesticides, which may be harmful to human health. Plus, some heavy metals could be absorbed by the plant, but the content is different for different areas of the world. Yet, there is insufficient evidence to suggest that this is the case, so eating goji berries does not pose a carcinogenic risk.” Do goji berries make you sleepy? Eva De Angelis says, “Goji berries have been linked to an improved sense of well-being and neurologic and psychological performance. Furthermore, because they are high in melatonin, the sleep hormone, they can improve our sleep quality with no side effects.” How many goji berries should you eat a day? You can eat 15 g of goji berries a day (8). This quantity is considered beneficial for eye health with 3 g of zeaxanthin in it. However, the safe daily limit of goji berries is not yet known.
