4) Risk of Low Blood Pressure (Hypotension)
Goji berries may lower blood pressure, which could be problematic for individuals already on antihypertensive medications. Consuming them alongside blood pressure-lowering drugs could cause dangerously low blood pressure levels. If you are being treated for hypertension, make sure to discuss goji berry consumption with your doctor.
5) Digestive Issues, Including Diarrhea
There has been a reported case where consuming goji berry tea led to bloody diarrhea and abdominal pain. It's worth noting that contamination could also be a contributing factor. If you have existing digestive problems, it’s important to seek medical advice before adding goji berries to your diet.
6) Potential Risk of Miscarriage
Goji berries contain betaine, a compound known to induce menstruation and abortion. Therefore, pregnant or breastfeeding women, as well as individuals with estrogen-sensitive conditions, are advised to avoid goji berries.
Recommended Daily Intake of Goji Berries
Goji berries are thought to promote eye health thanks to their zeaxanthin content, which helps protect against macular degeneration and other age-related eye conditions, with 3 grams typically found in a standard serving. A daily intake of around 15 grams is considered appropriate. However, the maximum safe daily limit for goji berries has not been clearly established.
