UPDATE: My three family members have continued to take the Vita C since September 2015. It is now mid January 2016 and I am happy to say not one of them has gotten a cold or flu let alone being hospitalized for double pneumonia as my uncle was last year. He has Alpha 1 COPD so pneumonia is THAT much more serious for someone in his condition. He has stayed healthy and strong this winter thus far and had an AMAZING recovery since he came out of two weeks in ICU in August/September 2015. He has a rare disease, CIPD, in addition to the COPD, that caused his diaphragm to paralyze in late summer! He was on a ventilator for one of the two weeks he was in ICU back in August into September of 2015. He could only whisper when they removed the vent. The doctors said his voice may never return. Well, it's back! And it's been back for a long time now! My Grandmom (91 years old!) who had a chordoma tumor in her pituitary had it surgically removed in February 2015. It came back so fast. :( She had gammaknife radiation in early August 2015. Began the Lypo-Spheric C after she had gammaknife and has been doing very well since then. She gets brain MRIs regularly. On a side note... beauty wise.... My grandmom and uncle have been taking the highest doses (2-4 packets a day) and I have noticed their skin looks incredible! I like to review products after they have proven the test of time. That being said, Myself, and 3 of my family members, have been using Lypo-Spheric Vita C for several months now. We all love it. It has helped my family immensely that had been experiencing significant health problems. Their health problems range from: Brain Cancer (chordoma brain tumor), COPD, CIPD, Dystonia, and Neuropathy. Even though I personally live an organic holistic lifestyle for over 15 years, my family does not, and has numerous health struggles from living a "mainstream" lifestyle. The point is, when people do not want to change their lifestyle, yet can take supplements that offer REAL results, without additional lifestyle changes, it is a highly impressive thing! This is one of those products. I only take about 1 packet a day, and usually mix with other forms of vita c (including homemade liposomal C) throughout the day. My family with above mentioned health issues take 3-4 packets a day. It has REALLY made a difference. We all consume them on an empty stomach. My family does not make homemade liposomal C (like I do) in addition to this product, nor have they made any additional lifestyle changes, but they are all reaping the benefits strictly through the packets from Livon Labs
