I received the damaged bottle. Asking them why, they reply just take it. Beware of this medicine. I don't believed it natural. It does have serious side effect exactly as all diabetes drugs. Even worse! My blood sugar drop so quick without any warning. Even after that I reduce only 1 pill per day. Please DO NOT fall for those scam on internet. This company is total scam. They are not in US. They are from Israel. You have no idea where are they. If you have any problem with this drugs you are out of luck! Go back to your Metformin ....or as your doctor prescription. It cheaper and safer. And forget about their return policy. This company not USA company. They are not follow the rule here.
