Dr. Mercola Berberine and MircoPQQ Advanced - Offers Metabolic, Mitochondrial, Brain & Immune Support - GMO-Free, Gluten-Free & Soy-Free - 30 Capsules (30 Servings)

I think this stuff is amazing and I personally feel it has helped lower my A1C.

This product has been supporting my son’s gut health for 3 months now and waooo!

I have not been able to take this regularly. It makes me feel tired, instead of giving me energy.I think everyone has different chemistry. This doesn’t really work well with mine.I have had better results when taking this at night. It seems to help me get better sleep, and I can sleep better throughout the night.The taste isn’t so great, it tastes bitter. But I just a lot of drink water with it.

I use lots of Dr Mercola’s products. Quality is consistent.

Dr Mercola gets a lot of bad press but I find his supplements to be superior to other brands I’ve tried. It’s quite an investment but worth it…

Received in afternoon mail, I took two with dinner I know it says one but though I'd get it in my system. Woke up next morning omg no pain in my shoulder no pain in my knees no snap crackle and pop as I got out of bed. Will be taking one every day for the rest of my life. Product works as you described, can't thank you enough.Thank you,Pete Silveira.

Dr. Mercola's products are awesome. That's why I keep buying them.

I purchased this product mainly because the source of the Berberine is Phellodendron Amurense which is not a commonly used source. The PQQ is an added benefit. I have been very happy with the product so far.Overall benefit being more energy & in my opinion better detoxification.
