Product Information


  • Stimulates enzymes that metabolize blood glucose
  • Promotes healthy blood glucose levels
  • Combats endotoxins

How it Works

Drawing from both Ayurvedic and Chinese traditions, Nature’s Sunshine Berberine IR promotes healthy levels of blood glucose. The formula regulates and activates enzymes that stimulate the metabolization of blood glucose. Modern diets, often high in carbohydrates, produce endotoxins that interfere with blood glucose levels. Berberine IR battles endotoxins to keep blood glucose metabolism functioning properly.


Berberine from Indian barberry

Recommended Use

Take 1 VegCap before a meal, three times daily.

Berberine benefits

Helps keep blood sugar under control. No medications.

Renee Place

Love all the Nature Sunshine Products. I have been with NSP since 1982. Added Berberine. And saw a big difference in my health. More energy and starting to lose weight.

More Investigation Needed

I'm not sure if this supplement gives me tremendous amounts of gas or not. I have since stop taking it, but will investigate it further in the future to make sure. Again, it could just be me, but it seems like my symptoms were worse when I started taking Berberine IR.
