Berberine is particularly well-known for its effects on blood sugar balance; multiple studies have validated these effects. In a 2009 study, for example, researchers found berberine significantly lowered fasting and postprandial blood sugar in a group of healthy adults. In the study, 48 adults with poorly controlled type 2 diabetes took 500mg of berberine daily for three months and experienced a significant improvement in blood sugar and cholesterol. Jenna Bush Hager Keto Gummies contains a much smaller dose of berberine: 30mg in a 4:1 ratio.
