I assume food grown sources are better… however I needed to ask a question about a product and was offered a free 15 minute consultation. The nutritionist I spoke to obviously knew her subject but I was told certain information could not be sent to me unless I completed a form and opened an account… This is a bit hard sell isn’t it!!?? On another matter, around the same time I was going to purchase the Bone Complex. I have looked up several retailers who list this item, including Wild Nutrition but I cannot see a list of ingredients/nutrients/Vitamins and minerals and the amount & percentage of RDA, etc. I also cannot see what form of calcium is used… calcium carbonate, citrate… or other source…. I find it very odd…. I guess the only way I’ll find out is to find the nearest shop that stocks it and travel there to read the label
