Hi John @bigjohnscho - I've been taking it since 2016 along with other recommended supplements but I don't have any pain with my neuropathy so can't say that it helps for everyone. I take it in hopes that it is slowing the progression or possibly has stopped the progression. I know starting out it causes nausea for some folks. A work around was to start with a lower dose capsules (100 mg) along with some food or a bite of a banana to help with the nausea until the body got used to it then keep adding to the dose until you reach the recommended dose - for me that is 600 mg morning and evening.

I think what really helped me more than any supplements I'm taking was a lifestyle change I made about 6 years ago after starting the supplements. I shared my weight loss journey in the Low-carb healthy fat living. Intermittent fasting. What’s your why? discussion here - https://connect.mayoclinic.org/comment/336050/.
Did your GP give you any suggestions on any changes you can make in your diet or lifestyle that will help improve your health and possibly get you out of the type 2 diabetes borderline category?
