2. BERBERINE Sometimes called “nature’s Ozempic,” berberine has become a social media darling for its purported weight loss benefits. Berberine is a bitter-tasting chemical found in a
variety of plants, including barberry and goldenseal. In supplement form, it’s often sold as a pill or powder. WHAT DOES THE SCIENCE SAY? A systematic review published in 2022 in the journal
_Frontiers in Nutrition_ found that berberine may hold some benefits for people with diabetes and other cardiovascular risk factors. Other studies have similarly found it can help people
manage blood sugar levels and lower cholesterol. Evidence for weight loss, however, is thin so far, and many health experts say more research is needed. “While some preliminary studies have
suggested that berberine may play a role in losing weight, there haven’t been many clinical trials (studies conducted in people), so there isn’t enough rigorous scientific evidence to
determine whether it is effective,” says the National Center for Complementary and Integrative Health (NCCIH). ARE THERE SIDE EFFECTS? Common side effects include diarrhea, constipation, gas
and upset stomach. Be aware that berberine can interact with a number of medications. The supplement can affect how the body breaks down other drugs, potentially increasing their effects
and side effects. Medications for diabetes, high blood pressure, blood clots, anxiety, sleep disorders and more all interact with berberine. It can also interact with other herbs and
supplements, including cannabidiol (CBD) and probiotics. According to the NCCIH, people who are pregnant or breastfeeding should not use berberine, and it should not be given to infants, as
it can cause or worsen jaundice in infants and could lead to a type of brain damage called kernicterus. 3. BILBERRY Bilberry — which comes from a bush native to northern areas of Europe and
Asia, the northern United States and Canada — has been used to treat a variety of conditions since the Middle Ages, according to the NCCIH. It’s considered high in antioxidant properties, so
it is marketed to reduce inflammation, improve vision, and lower cholesterol or minimize cholesterol buildup in the blood vessels. WHAT DOES THE SCIENCE SAY? A few studies suggest there
are some health benefits to bilberry, “however these studies involved small numbers of people,” the NCCIH says, meaning more research is needed to confirm any findings. For example, a
clinical trial of 24 adults, published in 2015, found that consuming bilberries helped to reduce gum inflammation and bleeding. Another 2015 study out of Japan found that bilberry extract
helped with eye fatigue. Little scientific evidence is available, and many more studies are needed to support bilberry’s use for cholesterol and inflammation. ARE THERE SIDE EFFECTS?
Short-term use is generally safe, the NCCIH says, however bilberry leaves may be unsafe when taken orally in high doses or for long periods of time, the center warns. What’s more, bilberry
may interact with the cancer drug erlotinib, used to treat some lung and pancreatic cancers. It can also interact with diabetes drugs and medications that slow blood clotting.
