I’ve been using the Marodyne for about 4 years and my DEXA scores improved significantly after two years of daily use. My hip score went from osteoporotic to osteopenic. My lumbar improved by 6%. Since that initial improvement, the scores were stable the following DEXA. I take no meds. I do supplement with calcium and turkey tail mushrooms, genestein , boron and MK7. I walk a lot and wear a 10 lb. weighted vest. I can’t say for sure if the LiV is the main reason but it certainly may be a factor. Best of luck!
