I have been using these for a couple of years, as recommended by my Naturopath. They taste vile!!! But do the job. I notice a difference in my energy levels and helps with mood stability. I add a drop of green-mandarin essential oil (not from this site) and it does disguise the taste better. I also take with Zinc mineral drops and Multi-Trace Mineral Drops. Together I think they are helping my body get what it needs but probably doesn't help with the taste.
