8 reports from women who tried Berberine
I've been using Berberine for about 8 weeks now for weight creeping up despite eating well. I felt a bit more like myself around week 4. my quality of life improved dramatically. Still taking it and plan to continue.
I've been using Berberine for about 12 weeks now for difficulty losing weight despite exercise. I noticed a subtle improvement around week 2. I felt significantly better. I'm glad I tried it.
I gave Berberine a fair trial for my bloating and fluid retention. Some improvement in mood stabilised slightly but the weight didn't shift persisted. Not sure if I'll continue long-term.
Mixed feelings about Berberine. mood stabilised slightly was noticeable, but my mood was still up and down didn't really improve. Not a miracle but not nothing either.
I gave Berberine a fair trial for my stubborn belly fat. Some improvement in energy improved but the hot flashes continued persisted. It might work for others but was modest for me.
