Barberry reduces insulin levels

Dr. Rebecca Tocher-Richmond, ND

Insulin is a hormone that controls blood sugar levels.  A person can have normal blood sugar levels yet high insulin.  I will often test insulin levels in my patients with PCOS (polycystic ovarian syndrome) or any of my patients that are having difficulty losing weight without obvious cause.  A patient may be told that they have normal insulin based on standard lab values but it might still be too high to effectively manage weight.   If I determine that a patient has high insulin there are some very effective nutritional and supplement measures to help.  I often use Barberry in my practice for patients with high insulin and this review of research supports this use.  In total, 7 studies, comprising 452 participants, were included in this systematic review. The meta-analysis revealed that barberry significantly reduces insulin levels.  I will continue to use this herb with confidence to help with weight loss.
