I have been taking their vitamins for more than 5 years and so do my sisters. It's the first vitamin that doesn't upset my stomach. I noticed the difference if I don't take them. I have dry skin that seriously improved. I have them on auto ship since they come from New Zealand and in all the years they never failed to show up. I get an email notification from a person who replies to me in their words, not a form letter if I need to change anything. I was first attracted because their label quantities are generally lower that the name brands but that's because they are designed to be released at the right time. I worried about taking too much of any thing. You take more pills every day with Xtend life but I never really thought one teeny little pill a day had all the stuff on the label. Anyway I'm not a health practitioner, just an ordinary person with zero qualifications, but I love this stuff and I smoke and besides the mercy of God I credit it for keeping me on my feet and well. I'm 58 and I am rarely sick. Maybe there's not a lot of information out there about Xtend life but bad news travels fast and I haven't heard any of that either.
